Then here is your chance to ask someone face to face! With around 2 months to go until the 2014 NovoPulp deadline passes, we wanted to give everyone a chance to raise their hand and ask the questions that the rest of us didn't. Even if you can't attend the Hangout live, please leave your questions so you can watch the video afterwards and still get the information you need. As the last HOA was aimed at the USA/Australian time-zones we have decided to make this Hangout more European friendly. The HOA will be on:SATURDAY 7th OF JUNE 2014 - 16:00 CET / 10:00 EDT Submission Status:We are still in need of more short stories for this year but in particular WE NEED ART. So don't be shy, step forward :DFor more information on NovoPulp: The Speculative Fiction Anthology visit: http://www.NovoPulp.comFor more frequent updates subscribe to our email list: http://eepurl.com/C_-QfComing soon: FREE Bonus Content Only For Newsletter Subscribers!See you on air!Notifications:You have been notified of this HOA because you have circled the +NovoPulp page at some point.

NASA Goddard80,247On March 29, 2014, an X-class flare burst off the right side of the sun . . . and NASA was watching.Coordinating their observations, five NASA observatories and one ground-based telescope were able to see things in the flare they'd never seen before.  Numerous other NASA spacecraft provided additional data about what was happening on the sun during the event and what the effects were at Earth. Join us at 2:30 p.m. EDT on Thursday, May 8, 2014, as researchers describe how multiple missions worked together to explore the sun's surface and atmosphere, layer by layer, providing unprecedented images of the onset of a solar flare.  In addition to the colorful pictures of the sun that NASA will share, participants will explain how such research can help scientists better understand what sets off these large explosions on the sun. Perhaps, someday scientists may be able to predict their onset, forewarning of the radio blackouts they can cause near Earth – blackouts that can interfere with military, airplane and ship communications.Participants include: Adrian Daw: IRIS project scientist at NASA GoddardAlbert Shih: RHESSI scientist at NASA GoddardSabrina Savage: Hinode deputy project scientist at NASA MarshallLucia Kleint: Bay Area Environmental Research Institute Jeffrey Newmark: NASA HeadquartersNASA Hangout: All Eyes on the Sun2014-05-08 20:30:00652G+

Show everyone your own sky! The best, the worst. I've seen people mention avoiding it because it means they have no "object" to shoot. Don't listen to those people.

James Honzik20,444Sharers Meta-circle VII:  This is a super circle, a meta circle of active , circle sharers, focusing on photography and art. This is version VII, bigger,  better, faster, wilder.  It's the only circle I share, and it's a good one. (and if you could, please look at my art and photography, that's why I do this - scroll down, I have lots of new and old good things)Thanks to everyone who looked, shared, and commented.Special kudos out to those who not only share, but post their own good things.I am trying out informing those included in this one, so if you have concerns please comment.Peace.

Marlo Angelo Tito99,896Sadie (SpectAcular rounD of Interesting plussErs)The next edition of this circle will undergo the 'usual' reboot of this circle. So the next one would be more likely to have a number of 380 members or something that is close to 400 or 350. And yea, the reboot of the named circle is kind of reversed...Note: If you want to suggest some people or yourself to be added in this circle, just tag them in the comments. :-D(let me copy-paste this one... lol)So folks, this is circle Saide. And yes, you know it, this circle is filled with normal folks here in G+. Well that is, it's your definition of normal! :-D. Since this is not a themed circle or whatsoever, this circle has a pretty great mix as it shows a great diversity among the people.

Lego for adults: At least for building houses : While the claims of green building seems a little over the top, the whole concept of the 'Smart Bricks' does bring out the geek in me. And getting a huge robot to build something for you is even cooler ;)

Article extract: Kite Bricks is currently developing a modular construction system that is so much like Lego, I’m not sure what’s harder to believe: the fact that this is serious proposal, that it doesn’t infringe the toymaker’s patent, or that no one has done it yet. The patent (pending) for their "Smart Bricks" reads like a legally binding contract for a particularly prescriptive playdate.

In comparison to standard bricks or concrete blocks, the Smart Brick claims to offer greater thermal energy control, lower construction costs and greater versatility. The specially formulated concrete blocks  aredesigned ... more »

Babies' Practice Speech before they are able to speak : Fascinating study coupled with some earlier posts about the way human babies recognize language. While I was first quite interested in how toddlers learn (see SAF - A Change of Mind.m4v ), there is more research now in this area, which is amazing to know about. University of Washington researchers have published a new paper which is linked to this post as well.

Article Extract: “Most babies babble by 7 months, but don’t utter their first words until after their first birthdays,” said lead author Patricia Kuhl, who is the co-director of the UW’s Institute for Learning and Brain Sciences. “Finding activation in motor areas of the brain when infants are simply listening is significant, because it means the baby brain is engaged in trying to talk back right from the start and suggests that 7-month-olds’ brains are alreadytrying to f... more »

Airwaveguide : While lasers have been used before to send information to satellites, this relatively new discovery is quite fascinating. Fibre optic cables are usually preferred due to having a high refractive index, and with fibre optic cables being encased in material having lower refractive index, it is possible to reflect the light back to the core of the cable, preventing the beam from losing focus. Now researchers are trying to do the same thing with air. How? Read more to figure it out...

Focusing the beam : Milchberg and colleagues' made the equivalent of an optical fibre out of air by generating a laser with its light split into a ring of multiple beams forming a 'pipe'. They used very short and powerful pulses from the laser to heat the air molecules along the beam extremely quickly. Such rapid heating produced sound waves that took about a microsecond to... more »

Focusing the beam : Milchberg and colleagues' made the equivalent of an optical fibre out of air by generating a laser with its light split into a ring of multiple beams forming a 'pipe'. They used very short and powerful pulses from the laser to heat the air molecules along the beam extremely quickly. Such rapid heating produced sound waves that took about a microsecond to converge to the centre of the pipe, creating a high-density area surrounded by a low-density area left behind in the wake of the laser beams.

Air 'Pipe' : "A microsecond is a long time compared to how far light propagates, so the light is gone and a microsecond later those sound waves collide in the centre, enhancing the air density there," says Milchberg. The lower density region of air surrounding the centre of the air waveguide had a lower refractive index, keeping the light focused. "Any structure [even air] which has a higher density will have a higher index of refraction and thereby act like an optical fibre," says Milchberg.

The findings : The researchers found the signal was 50 per cent stronger than a signal obtained without an air waveguide. The findings show the air waveguide can be used as a "remote collection optic," says Milchberg. "This is an optical fibre cable that you can reel out at the speed of light and place next to [something] that you want to measure remotely, and have the signal come all the way back to where you are."

The Prism : The prism fascinated me in school. I wondered how it would 'break' up light into it's constituent colors. That was what we were taught. But of course, there is so much more to why that happens. White light is not 'pristine'... it already has all the colors. In fact the colors are part of white light. To understand this, one has to ask 'what is color'. Color is nothing but our perception of the different wavelengths of light. Our perception of color is not the same as the perception of color which a mantis shrimp has for example (which sees much more of the EM spectrum than us) or a cat (which sees less of the spectrum than humans).

Of course the prism is just glass (or some transparent material). It sits on a triangular base and has rectangular sides. In school I imagined it was some special material !

Of course the prism is just glass (or some transparent material). It sits on a triangular base and has rectangular sides. In school I imagined it was some special material !

Refraction and speed of light in materials : Refraction simply means that light travels at a different speed in different materials. It's fast in air, and slower in water or glass. This has the effect of changing the direction of light, or bending it, when it moves from one material to the other.

But why do different colors go in different directions?  This is because different colors of light travel at different speeds in the glass. So from the analogy above, slower speeds in the glass make the light bend more. We call this effect dispersion, since it disperses the colors in different directions. Blue light travels slightly slower in glass than red light, so it bends a sharper angle when it enters the glass from air. In physics, we say the glass has a higher refractive index for blue light than red light. There is a formula (Snell's Law) that you can use to calculate angles from refractive index, or the other way around.

How refraction actually works (Quantum Electrodynamics) : Another way to answer this is through QED which talks about how light interacts with atoms of the material it is traversing. I will not even attempt to explain this here. But Richard Feynman got a nobel prize in Physics explaining the phenomenon. See Richard Feynman Lecture on Quantum Electrodynamics: QED. 1/8 . You can even get his book and read about it.

Deflector shields are a common Sci-Fi trope. Isaac Asimov actually used deflector shields as one of the key advances in the Foundation series. 

What are your favorite space opera stories with deflector shields?

Star Wars deflector shields : This is not news really. We have our own deflector shield on Earth. One which keeps us safe from harmful cosmic rays. Earlier posts on the Earth's shields here http://goo.gl/0E6j4W and here http://goo.gl/vb4uyY... Now Physics students have designed a concept for a deflector shield. With one problem...

Article Extract: Those fancy light shields they use in Star Wars to protect themselves against laser attacks aren't necessarily the stuff of science fiction after all. According to three fourth-year physics students at the University of Leicester, not only is the technology scientifically feasible, the science behind the principle is already in use today.

The students worked from the assumption that surrounding an object with a field of super-hot plasma, held in place by an electromagnetic field, would work in the same way. The denser the plasma, the higher the frequency of electromagnetic radiation (the laser blasts) would be deflected. There are a few problems, though. The first is that the magnetic field would have to be pretty strong to hold the plasma in place — requiring a larger generator than could fit on, say, an X-Wing. The other is that the shield deflects electromagnetic radiation — which includes, well, light. This would leave whoever was inside the shield unable to see anything outside.

Science Posts : are often about new discoveries or about science and related technology. I post a lot within this area. I have often found that while my posts have engagement, it gets hard to explain why the commenter has to stick to the science.

Why can't I talk about my experience : Of course you can, but one has to preface it by saying it is my experience, or its not something backed by research. And be ready to be called on it. Very often commenters will continue to talk about their experiences as if that 'proves' something. Experiences do not make science. It is an experience. What you observe may not be what another person observes. Or it may not be repeatable. (See the Scientific method here http://en.citizendium.org/wiki/scientific_method )

What you observe may not be what another person observes. Or it may not be repeatable. (See the Scientific method here http://en.citizendium.org/wiki/scientific_method )

How to make your point scientifically : Science posts may be wrong. That is the nature of science. Sometimes the science may be based on hypothesis which may have counterpoints, but these are continuously tested and refined. Theories are based on observations, so they have a body of work behind them. These are not 'guesses.' Be respectful to the original poster, since often science posts have a lot of work and research which has gone into it. Make your point with research from reputable sites and link back to the research. If you are not sure about it's veracity, ask an expert (There are many on Google Plus).

Does a study make it true : This one is fraught with issues. Often studies may not have a large enough sample size. Or the conclusions one may draw from a study may not be correct. Most scientists are extremely wary of making assertions, even in their own field. They know that there are a lot of variables which need to be taken into account. Science begins with skepticism. Every study needs to be evaluated.

Making your point : Oftentimes, you can make your point with just one comment on a post. Sometimes you make need to make a followup comment. Don't keep repeating your point, making the same assertion again and again. Talking over people does not make you right. It only makes them lose respect for what you are trying to say. Calling someone names is the lowest form of engagement. Do not let it sink to that level.

'Converting' someone : Don't comment to 'convert' someone to your point of view. Science is not about who talks louder or says it more often or cites more studies. Its about relevance, facts, study and repetition. (See my earlier post here How to do science : https://plus.google.com/110884604033336753419/posts/VJrxUt6gUmi )

Science doesn't play favorites : Mentioning Einstein does not make you right. Any scientist would tell you that there are things they do not know. The journey in science is the finding out. One has to live with things which are still not known, and scientists are the best at this way of being.

Join in the journey of finding out, rather than knowing : Science is fascinating. It is incredible. It really is. There is so much I learn just by reading and writing (researching) about how things work, its really something everyone should indulge in. It's brain food. Knowing something is the end of asking. Revel in the journey, not the end.

Food choices : This one is a doozy. Apparently we may be influenced by our gut microbiota to devour food, even some which may not be good for us. Researchers are not very clear how this happens, but the study is interesting. So we may not be zombies, but we can be controlled..... I say we are pwned !

Controlled : New research published this week in the journal BioEssays from researchers from UC San Francisco, Arizona State University, and the University of New Mexico says that the microbes that grow in our guts (known as the microbiome) might direct us to make food choices that will help them grow big and strong -- even if those foods make us grow big and fat.

Microbes manipulate us : Some of the foods that can enhance the fitness of the microbes include fat and sugar, which obviously isn't so great for the rest of our body. The exact way in which the microbes exert their influence over us isn't entirely clear, but the researchers postulate that they release some type of signaling molecule. "Microbes have the capacity to manipulate behavior and mood through altering the neural signals in the vagus nerve, changing taste receptors, producing toxins to make us feel bad, and releasing chemical rewards to make us feel good," says a statement about the research.

Balance of power : The speed with which the microbiome can change may be encouraging to those who seek to improve health by altering microbial populations. Optimizing the balance of power among bacterial species in our gut might allow us to lead less obese and healthier lives, according to the authors.

Possible Applications : "Targeting the microbiome could open up possibilities for preventing a variety of disease from obesity and diabetes to cancers of the gastro-intestinal tract. We are only beginning to scratch the surface of the importance of the microbiome for human health," she said.

How trees get ready for winter : Trees often have to survive -30 F temperatures. Some can even live through colder climes. Surprisingly, if the same trees had to live through the same cold temperatures in the wrong season, they would die. Trees have evolved to meet with all kinds of challenges. And while it looks like nothing much is happening in winter, there is a lot of science happening in the background.

Dormancy : The period of dormancy, where plants are ticking over but not growing, comes with the falling temperatures and reduced day length that winter brings. Dormancy is part survival mechanism, part housekeeping exercise, all meant to help plants gear up for warmer days ahead.

How trees get ready for winter : Trees often have to survive -30 F temperatures. Some can even live through colder climes.

And while it looks like nothing much is happening in winter, there is a lot of science happening in the background.

Dormancy : The period of dormancy, where plants are ticking over but not growing, comes with the falling temperatures and reduced day length that winter brings. Dormancy is part survival mechanism, part housekeeping exercise, all meant to help plants gear up for warmer days ahead.

Cold Hardiness : Scientists have found that short days and cold temperatures trigger the development of cold hardiness. But it isn't known whether the plant mechanism that slows growth also starts cold hardiness development or whether they just happen to occur simultaneously.

Slowing metabolism : A drop in temperature slows down a plant's metabolism largely because the enzymes that drive these biochemical reactions don't work so well in the cold. Photosynthesis slows, respiration slows, growth stops. A classic example is your backyard lawn, Atwell says, which stops growing over winter if the temperature is low for long enough. Being exposed to less sunlight also plays a role in grass growth this time of year due to the lower angle of the winter sun and shorter winter days, he says. That means less photosynthesis, which in turn means fewer sugars to metabolise.

Falling leaves : As winter approaches, leaves lose chlorophyll and the tree salvages its constituents — mainly nitrogen, magnesium and phosphates — for recycling. The nutrients are carried back from the leaves into the branches where they're deposited in the bark. Plant hormones (first auxin, then ethylene) then trigger the leaves, which are now largely stripped of nutrients, to fall off the tree.

Seeds : While there may be a little growth in the late summer, growth virtually ceases in the fall in preparation for winter. Entering a dormant state protects the buds from freezing temperatures. Mature seeds contain a complete embryo along with a reserve food supply—and mature seeds are formed within ripened fruit. If it were not for germination inhibitors present in the fruit or seed, the seeds would begin to germinate while still in the fruit.

Not just a predator, Terminator level achieved : The red lionfish ( Pterois volitans ) was assumed to be a just another predatory fish. Since it is an invasive species, it often decimates local fish populations. However, researchers have found that unlike most other predators, they do not move if their prey species dwindle and prey are harder to find. They actually wipe out the prey species to local extinction.... a very Terminator-like behaviour.

Article Extract: The finding of behavior that was called “alarming” was presented today by Kurt Ingeman, a researcher from Oregon State University, at the annual meeting of the Ecological Society of America. The new research concludes that lionfish, by comparison, appear to stay in one area even as the numbers of prey diminish, and in some cases can eat the population to local extinction.

Article Extract: The finding of behavior that was called “alarming” was presented today by Kurt Ingeman, a researcher from Oregon State University, at the annual meeting of the Ecological Society of America. The new research concludes that lionfish, by comparison, appear to stay in one area even as the numbers of prey diminish, and in some cases can eat the population to local extinction. They have unique characteristics that make this possible, and like the terminator, they simply will not stop until the last of their prey is dead.

The lionfish invasion in the Atlantic Ocean is believed to have begun in the 1980s and now covers an area larger than the entirety of the United States. Ingeman’s adviser, Mark Hixon, and fellow graduate students have shown that lionfish can wipe out more than 90 percent of the native fish in some hard-hit areas.

The arsenal : The Red Lionfish is a venomous coral reef fish. As with many species within the Scopaenidae family, it has large, venomous spines that protrude from the body, similar to a mane, giving it the common name lionfish. The venomous spines make the fish inedible or deter most potential predators.

Patents - is it time for a revamp? : Scientists and researchers have depended on patents from a long time ago. Science has progressed with the ability to protect an idea. But things have changed rapidly. Most recently +Elon Musk has famously gone open source. Is it time for us to work in an environment which fosters innovation? Are patent trolls and companies like Apple killing the whole concept? You decide. Maybe it is time to go back to defensive publishing, I'm not a lawyer, but its a real problem. I do understand that scientific institutions still depend on patents, and it has it's place.

Some of the issues are serious and will stop us from developing new drugs, increasing the cost of goods, get more people into legal tangles and stifle innovators and inventors. Read on....

Are patent trolls and companies like Apple killing the whole concept? You decide. Maybe it is time to go back to defensive publishing, I'm not a lawyer, but its a real problem. I do understand that scientific institutions still depend on patents, and it has it's place.

Some of the issues are serious and will stop us from developing new drugs, increasing the cost of goods, get more people into legal tangles and stifle innovators and inventors. Read on....

What is a patent? : A patent is a set of exclusive rights granted by a sovereign state to an inventor or assignee for a period of for an invention.

The Issue : Major companies are spending more on patent lawyers than research and development. Apple currently looks like the worst abuser among companies that actually make things.

Lawyers win : It is a machine created and run by lawyers, for lawyers, and which has absolutely no incentive to reform itself.

Unused patent-squatting : Of today’s 2.1 million active patents, 95 percent fail to be licensed or commercialized.  These unlicensed patents include over 50,000 high-quality patented inventions developed by universities.

Bloating the cost of research : More than $5 trillion has been spent in the U.S. alone on research and development over the past 20 years, much of which went to create the very patents that remain unlicensed.

Ignoring technologies : Rather than leveraging America’s patent database for useful ideas that could be licensed and turned to profit, U.S. businesses and their R&D teams are actually incentivized to avert their eyes to potentially helpful innovations.  Prior knowledge of a patent could result in increased penalties if companies are later deemed to be infringing that patent. So they ignore a goldmine of technologies.

Cost of frivolous lawsuits : In 2003, Apple patented the glass staircase that appears in some of their stores. In 2012, Apple successfully sued Samsung for creating a screen that can distinguish between 1 or 2 fingers touching it. They also sued Samsung for copying the iPhone shapes among other things.

Taste test : The sensation of taste is far more complex process than one had earlier imagined. It involves not only taste from the mouth, but involves smell, sound, texture and even memory. In the mouth, the tongue is covered with papillae which are composed of hundreds of taste buds. What role does taste play? And how is it important? Read on to know more. h/t to +Knut Torgersen for leading me down this path.

Article Extract: A bitter pill, sour grapes or sweet nothings – descriptions of taste are very often associated with strong emotions. They express in words states of intense pleasure as well as displeasure. The sense of taste influences food preferences and food choices. When people describe how food tastes, they are actually talking about food flavor which also includes aroma, texture, and mouth ‘‘feel’’—and, some would say, even the pleasantness of foods.

Taste test : The sensation of taste is far more complex process than one had earlier imagined. It involves not only taste from the mouth, but involves smell, sound, texture and even memory.

Article Extract: A bitter pill, sour grapes or sweet nothings – descriptions of taste are very often associated with strong emotions. They express in words states of intense pleasure as well as displeasure. The sense of taste influences food preferences and food choices. When people describe how food tastes, they are actually talking about food flavor which also includes aroma, texture, and mouth ‘‘feel’’—and, some would say, even the pleasantness of foods.

Where does taste come from? : Mouths also detect the texture and temperature of foods, and the chemical burn of chili peppers and other irritants. Other components of flavor (such as the aroma of vanilla or orange) are airborne particles that come directly through the nasal passages, or enter the nose from the back of the mouth. In more accurate terms, the basic tastes contribute only partially to the sensation and flavor of food in the mouth — other factors include smell, detected by the olfactory epithelium of the nose; texture, detected through a variety of mechanoreceptors, muscle nerves, etc.; temperature, detected by thermoreceptors; and "coolness" (such as of menthol) and "hotness" (pungency), through chemesthesis.

An evolutionary link : This strong link connecting taste with emotion and drive has to do with our evolution: Taste was a sense that aided us in testing the food we were consuming. It was therefore a matter of survival. A bitter or sour taste was an indication of poisonous inedible plants or of rotting protein-rich food. The tastes sweet and salty, on the other hand, are often a sign of food rich in nutrients.

Different tastes come from different chemicals : Saltiness is a taste produced primarily by the presence of sodium ions, Research has shown that TAS2Rs (taste receptors, type 2, also known as T2Rs) such as TAS2R38 coupled to the G protein gustducin are responsible for the human ability to taste bitter substances. Umami is the response to salts of glutamic acid, Sweetness is detected by a variety of G protein coupled receptors coupled to the G protein gustducin found on the taste buds. (for the sake of brevity, I have edited this from a number of sources. To know more, look at the links).

Other things you may not have known which play a part : Language, Utensils, Temperature, Color, Environment, Memory and expectations all play a part in the experience of taste. See http://www.popsci.com/article/science/7-things-affecting-your-sense-taste.

Neuroscientists object to EU's Human Brain Project : This one was a bit of a surprise for me, but, in hindsight, it is logical that the predictive simulations and direct research into human behavior issues would come to a head at some point.

While human behaviour is extremely complex, the two large HBPs are aimed at investigating the nature of the brain via simulations and fMRI results. A lofty goal indeed. Is it a genuine issue, or is it a storm in a teacup? Only time will tell; though the funding at stake is huge. But here are the facts:

Is it a genuine issue, or is it a storm in a teacup? Only time will tell; though the funding at stake is huge. But here are the facts:

Article Extract: More than 180 neuroscientists have signed an open letter to the European Commission calling on it to reconsider the technical goals and oversight of one of the world’s largest brain-mapping projects, predicting it is likely to fail. Governments, including those of the United States and China, have all launched large neuroscience projects to study the brain. But the brain is so massively complex—it has roughly 86 billion neurons and trillions of connections—that there’s little consensus on how to study it. “Why should an information technology project determine neuroscience funding?” says Zachary Mainen, a researcher at the Champalimaud Centre for the Unknown in Portugal, which gathered the signatures after a component of the project it was involved with was cancelled. “It’s not a project that was planned by the neuroscience community. They say they are going to simulate the brain, but I don’t think anyone believes that.”

The HBP : The European Union agreed last year to invest more than one billion euros in the Human Brain Project (HBP), a 10-year effort involving dozens of research institutions to create a simulation of how the human brain works, using supercomputers.

The criticism : That focus on computer simulations is what’s generating the most withering criticism. Konrad Kording, a neuroscientist at Northwestern University, calls the European project “useless and misleading” and says there is “genuine concern that the neuroscience community in Europe will be damaged by a very high-profile project that is deeply misguided.”

Response from the HBP : There is no question that cognition and behaviour are vital for the HBP. A group of cognitive neuroscientists was recently repositioned to what are called HBP Partnering Projects, where they can continue their independent investigations. The core HBP project will focus on building the ICT platforms. As they become established and evolve with detailed biological and theoretically inspired models, cognitive neuroscientists will be essential to experiment with the models and to perform biological
experiments.

Instead of mobile phone towers and street lights, imagine a world where trees light our way at night, are producers of oxygen and energy; and branches are antennae.

Boosting the signal : Chloroplasts aren't very efficient. They do not absorb green light (which is why most plants appear green) as well as the sun's heat, also known as infrared light. They generally waste a lot more sunlight than they use; photosynthesis maxes out at roughly 10 percent of the incoming sunshine.  What have scientists done? They have boosted plant's photosynthesis activity so that the efficiency is boosted by a factor of three.

Sensors and self-repair : In addition researchers have been able to make plants sensitive to certain substances, opening the path to their use as sensors; and enhance plant repair, allowing for the possible harnessing of plant energy as a fuel.

Nanoparticle infusion into plants : The first technique is known as "vascular infusion" and involves forcing under pressure a cerium oxide nanoparticle solution through the pores in the leaf from which water normally evaporates. In the second method, known as lipid exchange envelope penetration or LEEP, nanoparticles are coated with a highly negative or highly positive polymer coating that promotes absorption of the nanoparticle through the chloroplast membrane. Strano says as the membrane "re-heals" after absorption the nanoparticle is trapped within the chloroplast, which he calls the "engine of the plant".

Before the birth of the Sun : Monash University researchers have been investigating the period before the appearance of the Sun. While this is a combination of archeology and geology and astronomy. It only highlights that astronomers peer into the past - sometimes far beyond what anyone else does,  to come up with viable hypothesis on how our Sun was born. Interesting story which is part of our history.

Prehistory of the solar system : "Using heavy radioactive nuclei found in meteorites to time these final additions, we have got a clearer understanding of the prehistory of the solar system," Lugaro said.

Before the birth of the Sun : Monash University researchers have been investigating the period before the appearance of the Sun. While this is a combination of archeology and geology and astronomy.

Interesting story which is part of our history.

Prehistory of the solar system : "Using heavy radioactive nuclei found in meteorites to time these final additions, we have got a clearer understanding of the prehistory of the solar system," Lugaro said. "We can now tell with confidence the final one per cent of gold, silver and platinum, were added to the solar system matter roughly 100 million years before the birth of the sun. "The final one per cent of lead and rare-earth elements, such as those that make your smart phone, was added much later - at most, 30 million years before the birth of the sun."

Stellar nursery : Some time after the last addition of heavy elements the solar system matter went into an 'incubation' period, during which time the stellar nursery formed - where the sun was born together with a number of other stars. "We now know this incubation period could not have lasted more than 30 million years. This offers us the chance to determine the lifespan of the nursery where the sun was born, how massive it was and how many stars were born there together," Dr Lugaro said. "Ultimately, we want to have a clear understanding of the circumstances of the birth of our star and the prehistory of the solar system.

Stellar nucleosynthesis : The process by which the natural abundances of the chemical elements within stars vary due to nuclear fusion reactions in the cores and overlying mantles of stars. Stars are said to evolve (age) with changes in the abundances of the elements within. Core fusion increases the atomic weight of its gaseous elements, causing pressure loss and contraction accompanied by increase of temperature. Structural changes of the star (evolution) become necessary to stabilize it. Stars lose most of their mass when it is ejected late in their stellar lifetimes, thereby increasing the abundance of elements heavier than helium in the interstellar medium.

In comparison to standard bricks or concrete blocks, the Smart Brick claims to offer greater thermal energy control, lower construction costs and greater versatility. The specially formulated concrete blocks  are designed to be easily connected and include an internal space for the building’s insulation, mechanical, plumbing and electrical systems. Removable panels make it easy to install and access the building’s infrastructure. They can be easily assembled with just a little industrial double-sided tape and fit with custom finishing, so, like Lego, there’s “no additional need to paint, hang wallpaper or otherwise treat the outer and inner walls of the final structure."

Change Blindness : a surprising perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it. For example, observers often fail to notice major differences introduced into an image while it flickers off and on again. People's poor ability to detect changes has been argued to reflect fundamental limitations of human attention. Change blindness has become a highly researched topic and some have argued that it may have important practical implications in areas such as eyewitness testimony and distractions while driving.

How did Dinosaurs get Supersized? : I remember this kid who was really interested in Dinosaurs asking me this question. I did some digging and came up with some guesses. We still don't know for sure. But we have better answers to possible causes. Largely the higher levels of oxygen, the types of plants which existed (lack of flowers) the development of longer necks in Sauropods; all contributed to the supersized dinosaurs.

New information: The gigantism of these vertebrates, unique in the history of the Earth, raises many questions, such as why no other land creatures have ever achieved this size and what their bauplan, physiology, and life cycle would have been like. Although the bone structure and the density of certain tissues of sauropods were similar to those of today's mammals, the results do not conclusively demonstrate that sauropods were also endothermic animals.... more »

New information: The gigantism of these vertebrates, unique in the history of the Earth, raises many questions, such as why no other land creatures have ever achieved this size and what their bauplan, physiology, and life cycle would have been like. Although the bone structure and the density of certain tissues of sauropods were similar to those of today's mammals, the results do not conclusively demonstrate that sauropods were also endothermic animals. Werner and Griebeler discuss the hypothesis that a high rate of reproduction contributed to the gigantism of the large dinosaurs. They discovered that the reproductive pattern of most dinosaurs was similar to that of modern reptiles and birds. (http://goo.gl/OtAwuy)

Arms race : Some species of dinosaurs may have evolved to a larger stature as a way of escaping predators or gaining a competitive advantage. Studies of growth rings in dinosaur bones by Greg Erickson of Florida State University and others show that baby dinosaurs grew to maturity at dazzling speed. They practically exploded from their eggs. A bouncy little apatosaur could become a 30-ton beast in just 20 years.  Tyrannosaurs, the dominant meat-eaters of the late Cretaceous, grew steadily until they were teenagers and then went through a growth spurt, becoming five times larger in just seven years. That meant that one species came in two lethal sizes—medium and large—and could effectively dominate two ecological niches. But there's a problem with the simple bigger-is-better explanation: Most dinosaurs weren't giants. Small bones don't preserve as well, so the fossils (and museum displays) tend to overrepresent the behemoths. There were plenty of dog-size and even chicken-size dinosaurs, and one, known as Microraptor, no bigger than a pigeon. That guy was a real terror. (http://goo.gl/rdmPXt)

Long necks : In modern mammals, chewing muscles and the heads that have to support them have to grow larger relative to body size as absolute body size increases. Thus free from this constraint, sauropods were able to evolve relatively small heads that required far less energy to carry and to move around, thus allowing necks to elongate and feeding envelopes - the amount of food ("browse") that an animal can reach without having to walk - to increase. By swinging their tiny head around on a very long neck, a huge amount of browse is available at little energetic cost, allowing the evolution of faster food intake rates, larger guts and larger body mass. (http://goo.gl/x64Enm)

Flora : (Some) paleontologists suggest that some plant-eating dinosaurs might have gotten so big because the foliage in that era was extremely tough and woody: A larger body frame meant a longer digestive tract and more time for bacteria to do its work, allowing the dinosaur to extract as much nutritional value as possible from each bite.

Article Extract: Russian physicist Leonid Shkadov presented the megastructure concept in a 1987 paper at the 38th Congress of the International Astronautical Federation. In about a billion years our aging sun will become hot enough to boil off Earth's oceans. But we needn't let our world bake to death. By devising a megastructure called a Shkadov Thruster, we could cruise our solar system—sun, planets, and all—close enough to a younger star for it to gravitationally capture Earth. By enabling us to swap our sun for another, the Shkadov Thruster could give the planet's biota a brand new lease on life.

The Shkadov Thruster setup is simple (in theory): It's just a colossal, arc-shaped mirror, with the concave side facing the sun. Builders would place the mirror at an arbitrary distance where gravitational attraction from the sun is balanced out by the outward pressure of its radiation. The mirror thus becomes a stable, static satellite in equilibrium between gravity's tug and sunlight's push. Solar radiation reflects off the mirror's inner, curved surface back toward the sun, effectively pushing our star with its own sunlight—the reflected energy produces a tiny net thrust. Voilà, a Shkadov Thruster, and humanity is ready to hit the galactic trail.

'Minor Problems' : If humanity were ever crazy or desperate enough to build a Shkadov, the first order of business would be deciding where to place the megastructure. Much of the space-facing side of the thruster would probably need to be lined with cooling fins. These fins would radiate away excess solar heat in order to keep the mirror from deforming or melting, depending upon its material.

The thruster, of course, could not be positioned in Earth's orbital path. A logical spot for it would be above or below the plane of Earth's orbit, with the reflective mirror beaming energy mostly perpendicularly. For a thruster with a mirror angle of 30 degrees, the usual presumed curvature, Earth would still catch some extra rays.

The other problem is simply acquiring enough material to build the behemoth structure. Badescu estimated that 1/10,000 of Earth's mass would be required—probably about a sextillion pounds. Shkadov's figure is a bit higher, more like septillion pounds. Either way, it's hefty.

Space travelling a whole new way : Lining up our speeding solar system with the target star so that Earth seamlessly transfers into a nice, circular orbit around its new host would surely make for some hairy course correcting en route. Exquisite timing would be needed so that Earth, in its regular orbit, is situated on the side of our sun as near as possible to the other star for gravitational capture during the stars' close pass. Shkadov's original paper, however, suggested it could be done.

The Em-drive: NASA dabbles in speculation : The Em-drive was earlier called the Q-Drive. The claim that the Em-drive can convert electricity into thrust has been around for some time. But this time, NASA is paying attention. Apparently a Chinese team has built it's own Em-drive though most physicists remain skeptical. I am too.

Article Extract: Nasa is a major player in space science, so when a team from the agency this week presents evidence that "impossible" microwave thrusters seem to work, something strange is definitely going on.

Shawyer claims the EmDrive converts electric power into thrust, without the need for any propellant by bouncing microwaves around in a closed container. He has built a number of demonstration systems, but critics reject his relativity-based theory and insist that, according to the law of conservation of momentum, it cannot work.

A US scientist, Guido Fetta, has built his own propellant-less microwave thruster, and managed to persuade Nasa to test it out. The test results were presented on July 30 at the 50th Joint Propulsion Conference in Cleveland, Ohio. Astonishingly enough, they are positive.

'Refrigerator magnets' : The name is misleading ... just a tad, and the technology is a little ways off, but it's an interesting line of enquiry which is being followed by researchers at MIT. What they have done is shown theoretically that the motion of magnons (quasi-particles, which are actually collective rotations of magnetic moments in ferromagnetic materials ) are capable of carrying heat. This is the basic way that all refrigerators work. Except they do not use magnets!

Article extract: “You can pump heat from one side to the other, so you can essentially use a magnet as a refrigerator,” says Bolin Liao, a graduate student in MIT’s Department of Mechanical Engineering. “You can envision wireless cooling where you apply a magnetic field to a magnet one or two meters away to, say, cool your laptop.”

This is the basic way that all refrigerators work. Except they do not use magnets!

Article extract: “You can pump heat from one side to the other, so you can essentially use a magnet as a refrigerator,” says Bolin Liao, a graduate student in MIT’s Department of Mechanical Engineering. “You can envision wireless cooling where you apply a magnetic field to a magnet one or two meters away to, say, cool your laptop.”

In theory, Liao says, such a magnetically driven refrigerator would require no moving parts, unlike conventional iceboxes that pump fluid through a set of pipes to keep things cool. In many ways, magnons are similar to electrons, which can simultaneously carry electrical charge and conduct heat. Electrons move in response to either an electric field or a temperature gradient — a phenomenon known as the thermoelectric effect. In recent years, scientists have investigated this effect for applications such as thermoelectric generators, which can be used to convert heat directly into electricity, or to deliver cooling without any moving parts.

Liao and his colleagues recognized a similar “coupled” phenomenon in magnons, which move in response to two forces: a temperature gradient or a magnetic field. Because magnons behave much like electrons in this aspect, the researchers developed a theory of magnon transport based on a widely established equation for electron transport in thermoelectrics, called the Boltzmann transport equation.

“There’s still a long way to go for thermoelectrics to compete with traditional technologies,” Liao says. “Studying the magnetic degree of freedom could potentially help optimize existing systems and improve the thermoelectric efficiency.”

How to Science : Recently, I have been trolled pinged by a number of people who have asked me to talk about perpetual motion machines, thunderbolt universes, how magnetism affects mood, niburu or somesuch and a lot of other such stuff. One chap even 'debunked' the second law of thermodynamics based on a youtube video.... (keep your baloney detection kit ready).

Why science is important : Science is a method. Yes, we make mistakes, make assumptions, make hypothesis, which when supported by observations are elevated to theories.... and here is the main thing, we have to have observations that are repeatable, free of bias and need to be analyzed. This is an iterative process and involves external checks and balances, data recording and rigor.

Why science is important : Science is a method. Yes, we make mistakes, make assumptions, make hypothesis, which when supported by observations are elevated to theories.... and here is the main thing, we have to have observations that are repeatable, free of bias and need to be analyzed. This is an iterative process and involves external checks and balances, data recording and rigor. The first such process recorded (from Wikipedia) In the 7th century BCE, Daniel, a Jewish captive of the Babylonian king Nebuchadnezzar, conducted a scientific experiment complete with a hypothesis, a control group, a treatment group, and a conclusion.

Is there a way to find verifiable information : Sure, but it still needs to have rigor. A youtube reference is not a good benchmark. Most news sites are also not good indicators. Reputed science sites, reference papers and peer reviewed publications are good places to look. Even then not all of them are the best quality.

Why shouldn't I believe in flying chariots? The Nazca lines prove that chariots can fly : You are free to believe whatever you want. But remember, it is not something anyone will take seriously since your claim is based on belief, not proof or a method which involves rigor, repeatability and removal of bias.

Who should I ask? : Ask people who are experts in their field. There are quality scientists, chemists, biologists, physicists here on G+.... reach out and ask them. There are also sources like askamathematician where you can post your queries. They really do respond.

Black Holes: I had the distinct feeling of being trolled : But I read this article some time back, about how black holes may not have an event horizon. While it is a radical proposal, Stephen Hawking suggests that there may be an 'apparent horizon' which does release matter and energy, albeit in an garbled form. While others have reported this earlier, I wanted to digest some of the implications before I posted, so this is not news. Just interesting to know :)

Article Extract : “There is no escape from a black hole in classical theory,” Hawking told Nature. Quantum theory, however, “enables energy and information to escape from a black hole”. A full explanation of the process, the physicist admits, would require a theory that successfully merges gravity with the other fundamental forces of nature. But that is a goal that has eluded physicists for nearly a century. “The correct treatment,” Hawking says, “remains a mystery.”

The issue : Hawking's new work is an attempt to solve what is known as the black-hole firewall paradox, which has been vexing physicists for almost two years. In a thought experiment, researchers asked what would happen to an astronaut falling into a black hole. Physicists had long assumed, the astronaut would happily pass through the event horizon, unaware of his or her impending doom, before gradually being pulled inwards — stretched out along the way, like spaghetti — and eventually crushed at the 'singularity'. Polchinski’s team came to the startling realization that the laws of quantum mechanics, change the situation completely. Quantum theory dictates that the event horizon must actually be transformed into a highly energetic region, or 'firewall', that would burn the astronaut to a crisp. This was alarming because, although the firewall obeyed quantum rules, it flouted Einstein’s general theory of relativity. According to that theory, someone in free fall should perceive the laws of physics as being identical everywhere in the Universe — whether they are falling into a black hole or floating in empty intergalactic space. As far as Einstein is concerned, the event horizon should be an unremarkable place.

'Apparent Horizon' : Now Hawking proposes a third, tantalizingly simple, option. Quantum mechanics and general relativity remain intact, but black holes simply do not have an event horizon to catch fire. The key to his claim is that quantum effects around the black hole cause space-time to fluctuate too wildly for a sharp boundary surface to exist.

How carbon nanostructures can make better batteries : Lithium in today's batteries are in the electrolyte, not the anode.

Nanospheres to protect the Li anode : To solve these problems the Stanford researchers built a protective layer of interconnected carbon domes on top of their lithium anode. This layer is what the team has called nanospheres. The nanosphere layer resembles a honeycomb: it creates a flexible, uniform and non-reactive film that protects the unstable lithium from the drawbacks that have made it such a challenge. The carbon nanosphere wall is just 20 nanometers thick. The nanosphere layer is made of amorphous carbon, which is chemically stable, yet strong and flexible so as to move freely up and down with the lithium as it expands and contracts during the battery’s normal charge-discharge cycle.

Protection against expansion leads to efficiency : In technical terms, the nanospheres improve the coulombic efficiency of the battery—a ratio of the amount of lithium that can be extracted from the anode when the battery is in use compared to the amount put in during charging. A single round of this give-and-take process is called a cycle. Generally, to be commercially viable, a battery must have a coulombic efficiency of 99.9 percent or more, ideally over as many cycles as possible. Previous anodes of unprotected lithium metal achieved approximately 96 percent efficiency, which dropped to less than 50 percent in just 100 cycles—not nearly good enough. The Stanford team’s new lithium metal anode achieves 99 percent efficiency even at 150 cycles.

Inspiration from pomegranates : The story of this breakthrough spanned 8 years at the Stanford labs. Over the past eight years, Cui’s team has tackled the breakage problem by using silicon nanowires or nanoparticles that are too small to break into even smaller bits and encasing the nanoparticles in carbon “yolk shells” that give them room to swell and shrink during charging. The study builds on that work. Graduate student Nian Liu and postdoctoral researcher Zhenda Lu used a microemulsion technique common in the oil, paint and cosmetic industries to gather silicon yolk shells into clusters, and coated each cluster with a second, thicker layer of carbon. These carbon rinds hold the pomegranate clusters together and provide a sturdy highway for electrical currents.

Google X embarks on 'Baseline Study': An endeavor to pin down biomarkers : Reports suggest that Google X has launched a new 'moonshot' which is intended to better understand the human body.

Your guess is as good as mine.

Proactive medicine : The plan is to collect a massive amount of information on healthy people and to use that data to proactively identify and address health problems. Most medicine today is reactive rather than focusing on the prevention of illness—something goes wrong and then you get treatment. Once Google has a good baseline of what a healthy human looks like, that data can be compared to data from other individuals to discover potential problems before symptoms become obvious. +Larry Page has frequently spoken about the possibility of using big data techniques to improve healthcare while lamenting that privacy laws limit searches through medical data.

Long Shot : The report describes the project as being in the "early stage." The human body is influenced by very complex interactions among diet, DNA, and proteins, so the leaders of the project admit that it's a jump into the unknown. Like Calico and self-driving cars, this is a long-term effort that will take many years before we see if anything comes of it.

Privacy concerns : Information that is collected will include participants' full genomes and entire genetic history. Google has promised that all data collected as part of the research will remain private and will not be handed over to insurance companies. The medical school boards at Duke and Stanford Universities, which are involved in the project will oversee the research, recruiting the volunteers and ensuring that their data is anonymised before it is handed over to Google.

Bats use polarized light: Biologists in Germany and the UK moved some female greater mouse-eared bats around at sunset to demonstrate that they use polarized light to calibrate their internal compasses. The nocturnal animals calibrate themselves when they’re gearing up to be active, and this enables them to fly in the right direction when in search of food. If you could see these patterns, they would look like bands of light stretching 90 degrees away from the sun, across the zenith (top of the sky) and heading 90 degrees west. As you get very close and very far from the sun, the patterns are a little weaker. Like birds, bats apparently look at these patterns and use them to calibrate their magnetic compass.

What is Polarized light?: Polarized light is a characteristic of light bouncing around in Earth’s atmosphere. Water droplets, dust, airborne particles, and the air itself scatter light from the sun (literally why the sky is blue), but this scattering follows a defined pattern. The patterns depend on where the sun is in the sky. Polarization patterns are harder to distinguish during the day when the sun is high in the sky, and are much stronger at sunset and sunrise, when the sun is closer to the horizon.

How do they do it? : It’s not clear how the bats discern the polarized light, but it may be related to the type or alignment of light-detecting pigments in their retinas, the team suggests. The bats may have evolved to reset their navigation system using polarized light because that cue persists long after sunset and is available even when skies are cloudy.

Researchers have found that certain insects, birds, reptiles, and amphibians can also navigate using polarized light.

Other superpowers: Echolocation : To track down prey, avoid predators and find their way home in the dark, most bats depend on echolocation. They broadcast high-pitched sonar signals and listen for the echoes of sound waves bouncing off objects they’re looking for or obstacles in their path. Bats’ brains then process the auditory information within those echoes as visual maps. Scientists know a lot about the finer points of how echolocation works, but they differ on whether that sense evolved before or after bat’s ability to fly.

Earlier approaches : People have known for hundreds of years that it's possible to store energy using simple methods—pumping water up a hill and then allowing the force of gravity to turn cogs on its way down later to recoup energy, for example, or on a bigger scale, pumping air into a cavern then using its force at a later time to drive a turbine, is another. Until recently, however, such methods of energy storage have not been able to compete with batteries—at least on a large scale. That might be about to change, however, as the new ICAES system in New Hampshire demonstrates.

High Stakes : The stakes are high. If a company such as SustainX can deliver a system that can cheaply store energy for even a few hours at a time, it would turn wind and solar into dependable power providers, more like fossil fuel plants. Fluctuations in wind and solar output could be smoothed out and excess power from nighttime winds, for instance, could be dispatched later when demand is higher.

How it works : Researchers have looked into using compressed air as a battery before, what's new this time is the proprietary design created by the team at SustainX—its more efficient and is done at a much larger scale (it's capable of producing 1.6 MW of power when releasing the compressed air) than ever before. Also, they have developed a technique of spraying water into air filled cylinder chambers which allows for capture of heat generated by the compression process. SustainX says its ICAES systems are better than other methods of energy storage because they can be sited virtually anywhere (no need for a cavern), because they are flexible (easily scaled), because of the low installation and ongoing costs, and because installations will last for 20 years. It's also far cleaner than batteries or other systems that store compressed air.

The key is to contain the temperatures : Water’s properties make it a highly suitable heatexchange liquid: it is nontoxic and low-cost, has extraordinarily high heat capacity (joules of heat needed to heat or cool a kilogram by one kelvin), and is almost incompressible, i.e., can coexist with a gas that is undergoing pressure changes without itself changing in volume. SustainX has therefore opted for aqueous foam-based heat exchange in its isothermal compressed-air system (ICAES) technology.

Happy creatures : Well not really! :) While watching a TV show, I came upon these two creatures. The markings on the 'Happy-faced spider' makes it look like a cartoon version of a spider. The spider is actually a tiny little fellow (around 5 mm) from the Island of Maui. The fish is actually a Ray, called the thornback ray or it's scientific name Raja clavata. It is also called the Thornback Skate and is actually quite a common species. The so-called smiling face is a misnomer, as its 'eyes' which you see in the picture are actually gills.

Article link: The Happy-Faced Spider is a charismatic arachnid endemic to the Hawaiian Islands. T. grallator belongs to the comb-footed spiders (Theridiidae), a family which also includes the famous Black Widow. Happy-Faced Spiders are highly derived members of this group but do not share the venom toxicity of their more feared relatives. These are small spiders, about a quarter of an inch long, who prefer to live on the underside of leaves at elevations from 1,000 to 6,000 feet. Theridion grallator's common name comes from the interesting pattern on its abdomen, which closely resembles a 'smiley face'.

The thornback skate is probably one of the commonest skates encountered by divers, being among the most abundant rajids in the north-eastern Atlantic and Mediterranean. As with all skates, the body is flattened and disc-shaped, with the pectoral fins broadly expanded and joined to the head and body. The tail is distinctly demarcated from the disc-like body, relatively narrow, and about as long as body length. The upper surface of the disc and tail are covered with numerous thorns, which become thickened with button-like bases (known as bucklers) once the skate is sexually mature, hence the species' common name.

Water from thin air : A huge number of people on our planet do not have access to clean drinking water. I remember posting about this quite some time back, where two Italian designers carried forward a MIT concept of using bamboo and nylon to create a 'water condensation tower'. Christened "Warkawater" the structure was touted to collect as much as 25 gallons of water a day. Somehow it seems to have got buried. I was wondering if the proof of concept failed or they just did not have the connections to get funded.

Article Extract: The invention from Arturo Vittori, an industrial designer, and his colleague Andreas Vogler doesn't involve complicated gadgetry or feats of engineering, but instead relies on basic elements like shape and material and the ways in which they work together. At first glance, the 30-foot-tall, vase-shaped towers, named after a fig tree native to Ethiopia, have the look and feel of a showy art installation. But every detail, from carefully-placed curves to unique materials, has a functional purpose.

Process : The rigid outer housing of each tower is comprised of lightweight and elastic juncus stalks, woven in a pattern that offers stability in the face of strong wind gusts while still allowing air to flow through. A mesh net made of nylon or  polypropylene, which calls to mind a large Chinese lantern, hangs inside, collecting droplets of dew that form along the surface. As cold air condenses, the droplets roll down into a container at the bottom of the tower. The water in the container then passes through a tube that functions as a faucet, carrying the water to those waiting on the ground.

Funding constraints : In all, it costs about $500 to set up a tower—less than a quarter of the cost of something like the Gates toilet, which costs about $2,200 to install and more to maintain. If the tower is mass produced, the price would be even lower, Vittori says. His team hopes to install two Warka Towers in Ethiopia by next year and is currently searching for investors who may be interested in scaling the water harvesting technology across the region.

Dinosaurs and Dragons : This is not a new discovery, but the similarity to mythical dragons is striking. And no, humans and dinosaurs did not walk the Earth at the same time.

There’s no denying that Dracorex’s long muzzle and spiky horns conjure up visions of a magical beast, but the museum needed an expert to confirm that it wasn’t a coincidence that Dracorex looked more like a dragon than a dinosaur.

Dracorex is named Dracorex hogwartsia in honor of children’s author J.K.

Dracorex has a remarkable resemblance to the dragons of ancient China and medieval Europe.”

Dracorex may be a juvenile : Dracorex may actually be an individual of the closely related Stygimoloch and/or Pachycephalosaurus in which the dome and horns are not well-developed, either because the animal was a juvenile or a female. This consideration was supported at the 2007 annual meeting of the Society of Vertebrate Paleontology.

The find : The Dracorex Hogwartsia is known from one nearly complete skull and other fragments. It was discovered in the Hell Creek Formation in South Dakota by three inexperienced paleontologists and donated to the Children's Museum of Indianapolis in 2004 for study.

DARPA funds development of space plane for cheaper, faster satellite launches : The cost of putting up satellites in space is huge - not only from a viewpoint of the money involved, but also the effort and fuel expended.

Article extract: The Defense Advanced Research Projects Agency is looking for a way to reduce the cost and scheduling constraints that affect satellite launches. This week, DARPA announced the kickoff of the Experimental Spaceplane (XS-1) program, an unmanned reusable hypersonic vehicle that would carry a disposable second stage into suborbital space, launch it, and glide back to Earth—and be ready to be relaunched the next day. The goal of the program is to dramatically shrink the cost of putting 3,000- to 5,000-pound satellites into orbit, down to under $5 million per launch. That’s pocket change compared to current space launches, which can cost from 10 to nearly 100 times that amount.

The Department of Defense has already been testing a smaller experimental reusable spacecraft, the Boeing X-37B space "drone," which is in effect a robotic space shuttle. The X-37 rides to orbit on a traditional rocket first stage, however.

One of the few causes I think is excellent. +Charlie Hoover is the most helpful chap ever. No kidding, he actually did a custom check for my antivirus software. And I'm on the other side of the planet.

Calling All Geeks: Can I borrow five bucks? =)
TLDR: http://bit.ly/btckiva .

First off I want to apologize if this comes across as being spammy. I don't generally post things here that are self promotional but in this case I hope you'll all forgive me!

As some of you know, I quit my full time gig over a year ago to start my own business; a worker-owned tech support cooperative based in Somerville, MA called +Boston TechCollective. It's been a hell of a ride and I love not only what I do but my co-owners are some of the best people I've ever worked with!

We've grown considerably in a little over a year and at this point we could really use two people manning the shop and two people doing on-site/remote support. There are only three of us though! As you might imagine, it's stretching us very thin. We've got too much work but not enough revenue to justify hiring a part time person to lighten the load.

That's where Kiva comes in. It's a social lending site that allows people and organizations to get loans of up to $5000. Anyone who wants to support a project will eventually get their money back once the loan is repaid.

For us this relatively small amount of money will mean we can hire a part timer for our shop. That will mean that my co-owner +Yochai Gal will be freed up to do more on-site work (my primary job) which will generate more revenue. In the shop it would mean that +Matt Gabrenya would get some breathing room as well. Eventually we hope to make this part timer a member of our coop which would obviously be good for them as well!

In short it would give us the small boost we need to really get ourselves established!

So What Do You Want From Me?

All I ask is that if you can lend us even five bucks it would be wonderful. I know that times are tough so even if you can't lend, a reshare would be fantastic too!

Here is the link: http://bit.ly/btckiva

Thanks in advance to all of you. From the amazing crew that participates in my #gqotd  to the writers and assorted folks who follow my #gsotd  posts to the friends I've made via Hangouts I feel grateful to you all regardless!___One of the few causes I think is excellent. +Charlie Hoover is the most helpful chap ever.

Babies' Practice Speech before they are able to speak : Fascinating study coupled with some earlier posts about the way human babies recognize language. While I was first quite interested in how toddlers learn (see SAF - A Change of Mind.m4v ), there is more research now in this area, which is amazing to know about. University of Washington researchers have published a new paper which is linked to this post as well.

Article Extract: “Most babies babble by 7 months, but don’t utter their first words until after their first birthdays,” said lead author Patricia Kuhl, who is the co-director of the UW’s Institute for Learning and Brain Sciences. “Finding activation in motor areas of the brain when infants are simply listening is significant, because it means the baby brain is engaged in trying to talk back right from the start and suggests that 7-month-olds’ brains are alreadytrying to f... more »

The results emphasize the importance of talking to kids during social interactions even if they aren’t talking back yet. “Hearing us talk exercises the action areas of infants’ brains, going beyond what we thought happens when we talk to them,” Kuhl said. “Infants’ brains are preparing them to act on the world by practicing how to speak before they actually say a word.”

Motherese : Babies of parents who used more sound effects and motherese actually had better vocabularies when they were 2. The effects were the strongest when moms used sound effects around the 10 and 11-month babies.

"So much of science fiction has now moved to the realm of reality. We already have a real light saber, a real tricorder (well almost), holographic images, and replicators through 3D printing. 

"These are exciting times; as technology marches forward, so many of the science fiction tropes are coming to pass. If it's possible, someone is making it. For the first time makers and scientists are working in tandem to create what looked like an impossibility not too many years ago... What is next for science fiction?"

If you would like to read more it is as easy as joining our mailing list: http://eepurl.com/C_-Qf

Article Extract: Google first unveiled its smart contact lenses -- one of many projects to emerge from the mysterious Google X lab -- in January, but in an announcement today (15 July) it has revealed it will collaborate with global healthcare provider Novartis on the development of the lenses.

Novartis has licensed the technology from and will continue to develop the lenses designed by Google into a commercial healthcare product. Its eye care division Alcon will start to use the non-invasive sensors in the lenses to analyse tear fluid, which allows for constant measuring of blood glucose levels. This information will be wirelessly transmitted to smartphones or other devices with the idea being diabetes sufferers will be able to monitor their glucose levels in real time.

The second thing Alcon hopes to use the lenses for is to help people who are living with presbyopia -- a condition that means they can no longer read without glasses. By restoring the eye's natural autofocus, the smart lenses have the ability to provide "accommodative vision correction" either in the form of a contact lens, or an intraocular lens that can be implanted directly into the eyeball as part of refractive cataract treatment.

From Business Insider: A new patent application details how Google could add sensors and a micro-camera to the surface of a contact lens. The wearer would be able to control the lens by blinking, according to the application, which was unearthed by Patent Bolt.

If commercially made, it would mean your cellphone battery would last for three days.

Article Extract: Beach sand can be used to make lithium-ion batteries that last three times longer than current models. “This is the holy grail: a low-cost, non-toxic, environmentally friendly way to produce high performance lithium-ion battery anodes,” said Zachary Favors, a graduate student.

Typically the negative side, or anode, of lithium-ion batteries are made with graphite. Silicon has been eyed as a replacement material, since it can store about 10 times more energy--only it's difficult to produce in large quantities and degrades quickly. But perhaps the silicon in sand could provide a cheap, abundant source of silicon.

[Favors] ground salt and magnesium into the purified quartz and heated the resulting powder. In this very simple process, the salt acted as a heat absorber while the magnesium removed oxygen from the quartz, resulting in pure silicon. More than that, the pure nano-silicon formed in a very porous, 3D silicon sponge-like consistency. Porosity is one of the keys to improving the performance of battery anodes as it provides a large surface area and allows lithium ions to travel through them more quickly.

But I must admit I was astonished when one of the classic works in developmental biology — Peter Lawrence's book The Making Of A Fly — was offered on Amazon.com for $23,698,655.93.

Sure, that 1992 book is a classic and it is out of print. However, developmental biology, while it is fundamental to evolution, is a fairly narrow field. So overall, $23 million is more than you would reasonably expect to pay. And I was flabbergasted at how cheap the shipping price was — only $3.99, for a book costing $23 million.

The mystery was solved by Michael Eisen, an evolutionary biologist at the University of California at Berkeley. There were actually two different sellers or retailers offering the book. They were fairly substantial retailers, with over 8000 and 125,000 seller ratings respectively in the previous calendar year. When Dr Eisen first checked, the smaller retailer was charging $1.7 million, while the larger retailer had it for about $400,000 more, at $2.2 million. But the next time he checked, they had both gone up to about $2.8 million, with the bigger retailer only $5000 ahead. Then, the higher priced copy jumped to about $3.5 million. After a delay, the smaller retailer relentlessly followed their larger competitor upward.

It took a while, but Dr Eisen worked out the pattern. The retailer with 8000 seller ratings would, once a day, deliberately reset their price to be 99.83 per cent of the bigger retailer's price — they would always undercut them by the same tiny margin.

You'd have to think that anyone who fancied this book, and was keeping an eye on the price war, had another option. Once the book had reached 10 million dollars, surely it would have been cheaper to simply approach the author, Peter Lawrence, and offer him $5 million to move in next door and be available to answer your questions 24 hours a day? These computerised re-pricing programs continue to roam Amazon.com. Of course law books are expensive, but $84 million is a lot, even for a book called The Law of Mortgages.

60 Trillion Dollars : But the record seems to be held by a bioscience book, Recent Advances in Epilepsy. It was priced at around $60 trillion dollars — almost four times the US national debt.

Surprisingly, a few weeks later this book on epilepsy had dropped in price to just two cents — with, of course, $3.99 shipping.

How to attract a Jaguar to a camera trap : Apparently all you have to do is use Obsession for Men by Calvin Klein around the camera and wait for the magic. Jaguars are largely solitary animals and  is often described as nocturnal, but is more specifically crepuscular (peak activity around dawn and dusk). It's solitary and elusive nature makes it a hard animal to study, especially since sighting it is so difficult.

Article extract: According to Miguel Ordeñana a biologist from the Natural History Museum of Los Angeles you spray a men's cologne — that's right Calvin Klein Obsession for Men on a tree branch near the centre of your camera's field of view. This odd preference was discovered by a researcher at the Bronx Zoo in New York who tried a whole bunch of different scents and found that the jaguars really, really liked Obsession.

This odd preference was discovered by a researcher at the Bronx Zoo in New York who tried a whole bunch of different scents and found that the jaguars really, really liked Obsession.

Why? Well we're not really sure. But the best guess is related to the fact that Obsession contains two chemicals: civetone and vanilla extract. Perhaps the vanilla triggers the curiosity of the jaguar — we really don't know. But we know a lot more about civetone, one of the oldest-known perfume ingredients.

It's a musky chemical collected by glands near the anus of the civet, and it's widely used as a fragrance and stabilising chemical in perfumes. The poor animal that supplies the much valued civetone is the civet, a mostly nocturnal animal from tropical Africa and Asia. It looks like a cat but it's more closely related to a mongoose. Why would a jaguar be interested in civetone? Well, jaguars like to mark out their territory, and the civetone probably smells like the territorial marker of a potential invader. So the jaguar responds by rubbing its own scent on top of the cologne Calvin Klein Obsession for Men and bingo, it unknowlingly gets photographed.

So if you are on a bushwalk through the jungles of Nicaragua you might be better off not wearing Calvin Klein Obsession for Men.

Cube lightsail: Lightsail cubesat to be launched by Falcon Heavy : In a recent blogpost, +The Planetary Society announced that they would be launching a light sail (or solar sail) in Cubesat form via the +SpaceX Falcon Heavy. Why is this news? This would be the first time a Cubesat would demonstrate controlled solar sailing capability.

In a live webcast, The Planetary Society CEO Bill Nye announced that its long-awaited LightSail solar sail mission will launch to Earth orbit on a SpaceX Falcon Heavy, currently scheduled for an April 2016 liftoff.

LightSail will go to an orbit about 720 km above Earth, stored inside the Prox-1, which was developed by the Georgia Institute of Technology to demonstrate new technologies enabling two spacecraft to work in close proximity. After ejecting LightSail, the largely student-built Prox-1 will track and image LightSail, including the sail deployment.

There might be a test flight of a prototype LightSail-A on a smaller rocket, perhaps in 2015. This flight will only reach low earth orbit, where the atmosphere is too thick for a solar sail to function, but it will allow the LightSail team to check the operation of vital systems in the extreme environment of space.

Once at the comet Rosetta will follow it on its journey around the sun, performing extensive studies of the coma and the surface. And in November it will release the Philae lander, which if successful will be the first vehicle ever to land on a comet.

Rosetta will execute a pyramid-shaped orbit around the object, and it will employ the navcams to look for “landmarks” on the surface to understand where it is in space and how it is moving. Already, the science is beginning to flow. The probe’s Miro (Microwave Instrument for Rosetta Orbiter) spectrometer has reported the first detection of water vapour at 67P.

Rosetta is at a distance of about 43,000 kilometres from comet 67P/C-G, and by the end of the weekend will be less than 36 000 km; equivalent to the altitude that geostationary satellites orbit Earth. Rosetta completed the fifth in a series of ten rendezvous manoeuvres required to ensure the spacecraft’s arrival at the comet on 6 August.

The Onion :  The onion (Allium cepa) is used as a vegetable and is the most widely cultivated species of the genus Allium. The humble Onion has been cultivated and modified by humans for over 5000 years.  Onions have been used for their medicinal properties and in food down the ages.

What makes you cry when cutting an Onion? : The component in an onion that makes your eyes water is called lachrymatory factor, from Latin lacrima, or “tear.” (How appropriate is that!) Lachrymatory factor irritates the eyes and stimulate the tear glands to produce tears, much like the action of a tear gas. Onions are rich in two health-benefiting compounds: flavonoids and sulfur-containing compounds. Flavonoids are potential antioxidants that could protect us against cancer, heart disease, and aging.

Onions are rich in two health-benefiting compounds: flavonoids and sulfur-containing compounds. Flavonoids are potential antioxidants that could protect us against cancer, heart disease, and aging. They are often found at high concentrations in the skins and outer layers of onions with yellow or brown color (but some are masked by red or purple color). http://goo.gl/T7mPtI

Tear-free (GM) onions have been developed by Crop & Food Research (NZ) and in Japan : As a matter of fact, inhibiting lachrymatory-factor synthase would not only stop onions from making your eyes water, but would also increase the yield of thiosulfinate because all the sulfur compounds released from onions will be converted into thiosulfinate. So the onions lacking lachrymatory-factor synthase activity would be tear-free but retain that odor and flavor distinct to fresh onions. http://goo.gl/T7mPtI

How temperature affects potency : When temperatures drop, reactions take place more slowly because all the molecules have less energy. So, chilling onions in the fridge before chopping them reduces the amount of syn-propanethial-S-oxide that can be produced. Freezing the onions works even better, in fact it completely disables the enzyme, although it might make chopping a bit more challenging. http://goo.gl/zqhNxL

Common myths : Powering an Ipod with an onion, rubbing your hands with stainless steel reduces the smell of onions (This is a commonly held belief, but there is no scientific evidence to support it, though one can theorize why it may happen). Rub an onion on your foot and you can smell it 30 minutes later....This is definitely not true. Can onions reduce the smell of fresh paint (fumes)? .... there is some truth in this, though part of it is psychological.

Medicinal uses : Onions have been shown to improve cardiovascular health, blood sugar lowering abilities and blood thinning properties.

A Solar Home : Inspired by Ted Ewen's post (http://goo.gl/lfEaxu), I decided to investigate the possibility of living off grid. Considering there are many variables to look at, it may not be possible in all places. But here is some interesting information which you can look at from the viewpoint of Solar Energy.

Build in the costs : First look at the property you are looking at. There are many ways in which one can implement solar panels. Unfortunately, there are varying degrees of quality and efficiency as well as stability and irradiance. So it needs to be sized for the area you have available and the kind of power you consume.

Unfortunately, there are varying degrees of quality and efficiency as well as stability and irradiance. So it needs to be sized for the area you have available and the kind of power you consume.

Off-grid may not be ideal : Considering solar is is coming close to the price of grid power, you may want to sell to the grid. This is an ideal situation, so you would not require to have batteries to store power. You would still need an inverter to convert the DC to AC.... but that is unavoidable. If you keep moving power back to the grid, you can end up with a nice annuity income.

Capital costs: The highest costs are those of the land. Other costs such as the actual house, solar cells and the installation are usually a fraction of the land costs. In some countries, there are subsidies to allow you to lease the cells. If you do not consider the land and building costs, the cost of the project would depend on what you use. For a 1kWh system the pricing is around $2,000 in some countries.  This used to be $30,000 just 5 years back!

Future technologies : The case for solar technology is that power costs are always on the rise. We are also on the cusp of some very exciting tech such as OPV (Organic Photovoltaics) which are expected to crash the pricing down due to the lower cost of material and bulk processing (Roll to roll). These are semi-transparent flexible solar cells which are being refined. (Degradation and efficiency is still an issue). While the costs are expected to be less than 1/3rd of the current 1st and 2nd generation solar cells, the lifetime is also not more than 3-4 years (80% efficiency) and efficiencies are being improved as I write this. But organic photovoltaics may one day be on the roof of your car or the blinds on your windows.

Article Extract: This amazing microscope — a bookmark-sized piece of layered cardstock with a micro-lens — only costs about 50 cents in materials to make. Prakash’s dream is that this ultra-low-cost microscope will someday be distributed widely to detect dangerous blood-borne diseases like malaria, African sleeping sickness, schistosomiasis and Chagas.

“What came out of this project is what we call use-and-throw microscopy.” The Foldscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after use to safely dispose of infectious biological samples. With minor design modifications, it can be used for bright-field, multi-fluorescence or projection microscopy.

Twelve Foldscope variants are available, each designed to aid the identification of a particular disease-causing organism. To enable several people to use them at once, each microscope can project images with a built-in projector. The Foldscope is designed to be assembled by the end user, and hence is colour-coded to help with the assembly. Each unit costs less than one US dollar to build, with estimates varying from 50 cents to 97 cents.

What is a ferrofluid? : We have been seeing these gifs for some time now... often called 'science gifs' and 'amazing.' But what is the science behind ferrofluids? Ferrofluids are actually ferromagnetic particles (particles which can be magnetized) by means of an external field - often forming permanent magnets. At slightly larger than 15 nanometers, these particles act as domains and individual atoms clump together to display magnetism.

But smaller than 15 nm, the particles do not retain any alignment to an externally applied field. They 'flip' once the external magnetic field is removed. A ferrofluid uses this effect of superparamagnetism and once nano-sized particles of a ferromagnetic material are suspended in a surfactant, you have a fluid which can be easily magnetized and demagnetized.

But smaller than 15 nm, the particles do not retain any alignment to an externally applied field. They 'flip' once the external magnetic field is removed. A ferrofluid uses this effect of superparamagnetism and once nano-sized particles of a ferromagnetic material are suspended in a surfactant, you have a fluid which can be easily magnetized and demagnetized.

Superparamagnets: Superparamagnets have fluctuating magnetic moments with no applied field, but with an applied external magnetic field they become magnetized easily. This effect is size dependent. What are magnetic moments? These are nothing but the spin of the electrons in a material.
                                                         
Uses: Ferrofluids are made up of tiny magnetic fragments of iron suspended in oil (often kerosene) with a surfactant to prevent clumping (usually oleic acid). There are many commercial applications for ferrofluids--speakers and hard drives being the most common. The oily fluid prevents debris from entering hard drives when a small amount is placed between the magnets and shaft. In the case of speakers ferrofluids remove heat from the voice coils and help dampen the cone movement. They are also being studied as a contrast agent in MRI scans.

Mind-Controlled Quadcopter  : A team of researchers at the University of Minnesota has just created a quadcopter that can perform feats of aerial agility, controlled entirely by the pilot’s thoughts. Using electroencephalography (EEG), a non-invasive cap fitted with 64 electrodes reads the electrical impulses of the brain to control the copter. Thinking of making a fist with the left hand, for example, fires off certain neurons in the brain’s motor cortex; the cap interprets this pattern and sends a command to the copter to turn left. (http://goo.gl/ob8EVj)

Using the brain to control rats : Researchers at a Cambridge, Mass.based university were able to use a human mind to control the physical movement of a live rat. A human wears a standard EEG-based "brain-to-computer interface" (BCI) while the rat wears the reverse "computer-to-brain interface" (CBI,) according to a report from ExtremeTech.com. The rat's interface also includes non-invasive technology that can excite a specific region of neurons the wearer's brain using an ultrasound signal. (http://goo.gl/SHlYGN)

Pilots of the future could be able to control their aircraft by merely thinking commands : The scientists have logged their first breakthrough: They succeeded in demonstrating that brain-controlled flight is indeed possible - with amazing precision. Seven subjects took part in the flight simulator tests. They had varying levels of flight experience, including one person without any practical cockpit experience whatsoever. The accuracy with which the test subjects stayed on course by merely thinking commands would have sufficed, in part, to fulfill the requirements of a flying license test. "One of the subjects was able to follow eight out of ten target headings with a deviation of only 10 degrees," reports Fricke. Several of the subjects also managed the landing approach under poor visibility. One test pilot even landed within only few meters of the centerline. (http://goo.gl/fUfZd3)

What are Plasmons? : Consider a thought experiment. If we have a sheet of metal with holes in it (pic bottom right) and we shine a torch through it, we find that the amount of light which makes it through to the other side depends on the size of the holes. Smaller the holes, less is the light which makes it through. But when the size of the holes is around half the wavelength of light, almost 80% of the light makes it through. This is even though the holes are less than 30% of the metal plate. How is this possible?

Plasmons are surface waves on the metal plate itself : The incident light on the metal plate excites the electron waves on the surface of the plate. The sloshing electrons on the metal plate behave like a fluid and propagates along the metal plates and through it. (See pic top right)

So what is special about plasmons? : They are coupled excitation and also give... more »

Smaller the holes, less is the light which makes it through. But when the size of the holes is around half the wavelength of light, almost 80% of the light makes it through. This is even though the holes are less than 30% of the metal plate. How is this possible?

Plasmons are surface waves on the metal plate itself : The incident light on the metal plate excites the electron waves on the surface of the plate. The sloshing electrons on the metal plate behave like a fluid and propagates along the metal plates and through it. (See pic top right)

So what is special about plasmons? : They are coupled excitation and also give rise to an oscillating electromagnetic field. This field can be huge near the surface.

Ripples : A plasmon is a collective excitation of the electronic "fluid" in a piece of conducting material, like ripples on the surface of a pond are a collective mode of the water molecules of the liquid. These electronic ripples can have a well-defined wavelength (which quantum mechanics tells us is related to their momentum). What makes them have a frequency? That is, what makes the plasmon waves wave? When the electrons are displaced, the positive charge left behind exerts an attractive force on the electrons, trying to pull them back to their original positions. This interaction is what makes the plasmons oscillate once they're excited. (See pic right middle, courtesy Wikipedia)

Other uses: Plasmons have also been proposed as a means of high-resolution lithography and microscopy due to their extremely small wavelengths. Surface plasmons are very sensitive to the properties of the materials on which they propagate. This has led to their use to measure the thickness of monolayers on colloid films, such as screening and quantifying protein binding events.

Nanoprobes as explorers and more : Getting to asteroids is an expensive business, especially the cost per weight in sending anything out of earth's orbit is around $1 million for every kilogram. Space agencies and researchers are always looking for cheaper, more efficient ways to explore asteroids. One such proposal caught my eye. Especially since it involves the Nano world.

Visiting Asteroids With Fleets of Nanoprobes : The proposal, known as the Swarm Flyby Gravimetry, was recently awarded a Phase I grant in the NASA Innovative Advanced Concepts (NIAC) program. The goal of the swarm is to create a cheap, fast way to study asteroids by using dozens of microprobes that would scatter around an object in space. A larger probe would gather all the measurements of their movements around the asteroid and combine them into a more complete picture. (Nanoprobes need to be small and... more »

The goal of the swarm is to create a cheap, fast way to study asteroids by using dozens of microprobes that would scatter around an object in space. A larger probe would gather all the measurements of their movements around the asteroid and combine them into a more complete picture. (Nanoprobes need to be small and cheap, since losing a few in the process of taking the measurements is par for the course.)

The probes could simply reflect light, which would help infer gravity by their position and the way they scatter around the asteroid. Another version might use simple probes armed with LEDs, which would use a similar concept, but light up rather than use reflective light, and use different LED colors to track movements of particular swarm members. (From +Popular Mechanics : http://goo.gl/g1O9uG )

Using NanoFET Propulsion : The Nano-particle field extraction thruster or NanoFET is an experimental high-speed spacecraft engine under development by the University of Michigan. It provides thrust by emitting charged particles. These particles are cylindrical carbon nanotubes which can either be contained in tanks or manufactured in-flight. By varying the size of these particles, the nanoFET can vary its fuel efficiency (specific impulse), and consequently the amount of thrust output, while maintaining high power efficiency. This adjustability gives the nanoFET the performance characteristics of all the electric thrusters in one. Like other electric propulsion systems, the nanoFET is not intended for operation inside earth's atmosphere but for operations in orbit and deep space. (From Wikipedia : http://goo.gl/x0aYgJ )

While the pic shows a concept for ground vehicles, manufacture of nanomachines is the true challenge. We are still some time away from being able to do this.

Infrared Dawn : I have been following the next big story in astronomy, and that is undoubtedly the emergence of the James Webb Space Telescope (JWST) which is an origami-inspired infrared telescope which will be placed most probably in the Lagrange point (L2) which means after unfolding, the telescope will keep up with the Earth's revolution around the Sun. Why is it exciting? It is like a Hubble on steroids. Astronomers don't even know how much they will learn once the JWST sees first light.

Article Extract: Ball Aerospace had delivered all 18 hexagonal segments of the observatory’s honeycomb-like, 6.5-meter primary mirror, designed to look into a past 13 billion years distant. From an observation platform, you could see one of the mirrors on display in the Spacecraft Systems Development and Integration Facility, the largest clean room in the world.

Article Extract: Ball Aerospace had delivered all 18 hexagonal segments of the observatory’s honeycomb-like, 6.5-meter primary mirror, designed to look into a past 13 billion years distant. From an observation platform, you could see one of the mirrors on display in the Spacecraft Systems Development and Integration Facility, the largest clean room in the world.

Two decades after astronomers first convened to discuss what sort of space-based observatory should succeed the Hubble Space Telescope, Hubble’s three-times-as-large, 100-times-as-powerful replacement, whose fabrication was overseen by primary contractor Northrop Grumman, finally seemed to be coming together. “Going from Hubble to the James Webb Space Telescope is like going from a biplane to the jet engine,” said Mikulski.

No one disputes that the Webb will be an extraordinary machine, one that will allow astronomers to look farther back in time than they’ve ever been able to see, to the earliest galaxies that formed after the Big Bang. The gold coating on its mirror segments, totalling about a golf ball’s worth and spread in a thin layer across the surface of each segment, will absorb light on the blue end of the spectrum, allowing the observatory to see a bandwidth between 0.6 to 28 microns, firmly in the infrared and stretching just slightly into the visible spectrum.

Amazing discoveries ahead : Once [we] started seeing things with Hubble that [we'd] never seen before, [we] pushed it harder and harder to do new things. The same will happen with the James Webb Space Telescope. We will discover new things that we have no way of knowing about today, no way of guessing [because] our intuition isn't able to take us there. And those will be the great discoveries that actually show up in the coming 20 years, in the coming 30 years. It is really, in many ways, the golden age of astronomy — it's the very best time ever to be an astronomer. (Michael Shara)

Love me love my microbiome : Some researchers are now considering the microbiome as a separate organ.  What is the microbiome really? The human microbiome is the is the sum total of microorganisms, that resides in the skin, saliva, GI tract, in fact all over and inside the body. They include bacteria, fungi, and archaea. Some of these organisms perform tasks that are useful for us. However, the majority have been too poorly researched for us to understand the role they play.

How does it all work? : We used to think our relationship with bacteria was simple; there were good ones that kept our digestive tracts healthy and there were bad ones that made us sick. We now know that many bacteria can play both roles, living happily in us or on us as part of a healthy microbiome, but capable of turning nasty under certain conditions.

We now know that many bacteria can play both roles, living happily in us or on us as part of a healthy microbiome, but capable of turning nasty under certain conditions. Now there are claims that a truly villainous bacterium – Mycobacterium tuberculosis, which causes TB – is actually symbiotic and helped us evolve our large brains.

Your mobile phone carries your microbiome : James Meadow and colleagues from University of Oregon used DNA sequencing to compare bacteria living on the skin of smartphone users with those living on their phones. “We found that we each have more bacteria in common with our own phones than with anyone else’s,” Dr Meadow said. “This opens up the possibility that we might be able to use this biological connection to understand more about the microbes that are carried around on our bodies and on our personal effects.”  (Article source: http://goo.gl/KZr4Au and related paper https://peerj.com/articles/447/ )

You share your microbiomes with your pets : Well dogs at least.... A new study finds that families share skin, tongue and gut microbes with each other... and their dogs. The study shows how the people and pets you live with affect the microscopic bacteria, fungi and other creatures living all over your body. As with other family members, adults share more microbes with their own dogs than they do with other people's dogs. But the researchers also found that simply owning a dog seems to have an effect on overall microbe-sharing. Cohabiting couples shared more microbes with one another if they had a dog, compared with couples that didn't have dogs. Dog owners also had more species in common with other dog owners than they did with puppy-less people. ( Popsci source: http://goo.gl/kxjyfs )

Soil microbiomes can set plant flowering times : Scientists grew plants in soil inoculated with microbes to study the flowering time phenotype. Researchers wanted to learn more about the impact of soil, and specifically of the microbial communities in soil, on a plant's flowering time. Flowering time has been known to been affected by factors such as temperature, water availability and pathogens, and the team wondered if microbes could also affect this particular trait in a plant's phenotype.
