NASA Goddard117,839On 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 20:30:00650

Marlo Angelo Tito110,118Xena (eXtraordinary circlE of eNgAgers)I'm very sorry for the delay of this circle. I got confused on the "release dates" of this circle and my snowball circle, thinking my snowball circle gets to be released on a Wednesday/Thursday and this circle gets to be released on a weekend. I've already fixed that problem so you have nothing to worry about. :-D(let me copy-paste this one... lol)So folks, this is circle Jameson. 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. As I am done introducing these folks to you, you're might want to add them to know more! :-D  If you want to get into this circle, just tell me!And also if you want to be excluded from this circle, please also do tell me!This circle rolls every Wednesday or Thursday.SongS for the Week! Hungry Ghosts - I Don't Think About You Anymore But, I Don't Think About You AnylessDeerhunter - Helicopter (Official Video)Have a nice day and God bless! :-D #CIrcle   #circleshare   #circlesharing   #circleoftheday   #shared   #sharedcircles   #sharedpubliccircles   #sharedcircleoftheday   #sharing   #sharingcircles   #sharingiscaring   #sharingmeansthankyou   #add   #addcircle   #addpeople   #justanaverageteenagerwhoexpresseshisopinionsovertheinternetcircle  2014-10-09 14:25:57335119102152

Urgently looking for some information / help : I am sending this post out for a  friend who is currently battling with cancer. I wanted to help, and ask our G+ community at large if there are people who understand how this works (preferably oncologists, radiologists and similar people in the field) and who might be able to guide me as to what are the therapies which are possible.

Of course I realize that this is not one disease, and therefore much more information needs to be shared (privately), but I am making a public post to appeal to people who have knowledge of the therapies, maybe are doctors and could help with clinical trials or guiding my friend in Europe of what can be done and how to go about it.

Frankly, I am not an expert, and I don’t even know the right questions to ask. If someone is able to even frame those questions, even that would help with my friend, whoca... more »

EU Researchers look for alternate means of controlling pests : In an interesting article. some of the ideas are quite fascinating. Researchers are working on using sound, odor and other methods to reduce the amount of pesticides used. As of now, this is all under study and is not proven technology. But the ideas sound promising.

Article Extract: Scientists in Northern Italy are experimenting with unusual and totally eco-friendly sound and odor devices to fight off insects from their cultivated fields. And their studies suggest that these methods could be as efficient in protecting crops as using chemical based pesticides. In the meantime, in a field study near Pisa, Italy, researchers are learning how important it is to keep semi-natural habitats next to cultivated fields. These areas are an important resource for pollinators and it now seems they even have an impact on the yield of the... more »

Bad research : No sense in putting this any other way. I have often come upon some paper which talks about a small sample size, where sample size is important to understanding statistically significant effects. Sometimes the bias in an experiment has not been addressed. In other cases, repeatability is a problem.

Why does this matter? : Imagine a simple thought experiment. First we make an assumption - e.g. eggs come from birds. We need to first define 'eggs' and 'birds'. Is this rigorous? When an experimenter finds that a fish lays an egg, the assumption is clearly not specific enough. What does 'comes from' mean?

Assuming for this example, that only birds lay eggs, and we have defined the terms adequately, we then need to go on and test this idea.... if an idea is testable, repeatable, has some logic and has a clear explanation, we can call this... more »

Assuming for this example, that only birds lay eggs, and we have defined the terms adequately, we then need to go on and test this idea.... if an idea is testable, repeatable, has some logic and has a clear explanation, we can call this a 'hypothesis'. But we need to check; do all birds lays eggs everywhere we test? Does a bird give birth any other way? Has there been a single case of a bird not laying an egg? Has it been done in all kinds of conditions, multiple times, by different researchers? Is there some bias that can creep into the way we observe this egg-laying phenomena? Hypothesis are based on the scientific method, and means something in science.

Hypothesis --> Theory ---> Law : This is a long journey from our initial assumption. The UC Berkeley website says " Occasionally, scientific ideas (such as biological evolution) are written off with the putdown "it's just a theory." This slur is misleading and conflates two separate meanings of the word theory: in common usage, the word theory means just a hunch, but in science, a theory is a powerful explanation for a broad set of observations. To be accepted by the scientific community, a theory (in the scientific sense of the word) must be strongly supported by many different lines of evidence. So biological evolution is a theory (it is a well-supported, widely accepted, and powerful explanation for the diversity of life on Earth), but it is not "just" a theory. "

Feynman explains : Richard Feynman describes the way the scientific method works (Feynman on Scientific Method. ) and here he is again on the social sciences : R. P. Feynman on social sciences

Researchers published results damaging their own work : This is how science works. Things change and researchers like Sarah Brown-Schmidt and Sid Horton actually published a paper saying their own work was not repeatable. This is all kinds of awesome . Read more about it here http://goo.gl/wVXYdK

What to look for : Matter of belief and opinion cannot be researched. If that is the basis of the study, its bad science. Sample population is important and how it was selected. Did the researchers study one variable at a time? Did they have a control group to test against? Were all the variables controlled? Was it a double blind test? (not always possible). Was the conclusion statistically significant?  ------- There are many other basic ideas you can check for. I saw a research on an effect, where the experiment was done only once. The experimenter was himself a part of the experiment and the conclusions seemed to be a matter of opinion. That is just bad research. No other way to call it.

Car of the future : In keeping with some of the thoughts I've been having on technology and what role it plays in our lives as to lowering carbon emission and providing cheaper and more reliable energy, here is my view of what would make a car of the future... besides the obvious improvements on weight, safety and 'smart cars' what powers the ubiquitous car for humanity will be key to managing carbon emissions. I am very aware that this needs to look at LCA for each type of vehicle.

Virus powered batteries : Biological engineer Angela Belcher is genetically modifying viruses to create batteries that can be recharged thousands of times and then decay harmlessly.

See earlier post 'My dream is to make a virus powered car' (http://goo.gl/hPZ7Bd). Belcher speaks regularly about her work and inspirations. To her, evolution is a billion year nanotech experiment. The physical features of every living thing on earth are built from the bottom up by our genetic code. Viruses are the simplest living things to work with. Belcher has three main viral-battery innovations to her name: the lithium battery with virus electrodes, the water-splitting virus fuel cells, and the virus-nanotube solar cell.

The Hyundai 'Photosynthesis car' concept : The car’s body consists of transparent solar panels, which "collect ambient light" and create electricity. Now, that current doesn’t simply power an electric motor. The electricity is fed into a water tank to split the hydrogen from the oxygen. The hydrogen is stored and used to power the vehicle while the pure oxygen comes out the exhaust. The car essential functions like a plant does, with its own version of photosynthesis. (http://goo.gl/NZaRu4)

Regulation plays a role : In the 1970s to early 1980s, we doubled the fuel economy of cars. And then starting in the mid-80s, we stopped. Mileage standards remained unchanged from 1985 to 2007, and truck and S.U.V. sales almost doubled. Because these vehicles have lower standards than cars, average fuel economy today is actually a bit less than it was 20 years ago, despite hard-won gains in engine efficiency. (PBS transcript of 'Car of the future' http://goo.gl/j8Dvbw)

3D Printed cars : the 3D printed car ‘the strati’ was printed and assembled at a exhibition, the full-scale and fully functional vehicle is an investigation for the usage capabilities of a hybrid additive/subtractive machine developed at oak ridge national laboratory, and the car was driven off after printing.

Low-carbon economy : As a part of my Climate change course, a peer-reviewed essay on what a low-carbon economy would look like was part of the requirement. Instead of writing about climate change refugees (which was the other option), I decided to look at how I would envision such an economy. I must confess, I would have included organic-inorganic buildings and more radical solutions if I had more leeway, but as per the rubric, here is my essay....

A Low-Carbon Economy would be one which invests in new technology as well as in managing consumption. As a counterpoint to the heavy energy draining economies, a low-carbon economy would be one which creates jobs and resources in areas such as nuclear fission and fusion research[1].

Instead of using coal, natural gas and petroleum, it would focus on hydroelectricity, solar and wind power as well as harnessing the energy from... more »

A Low-Carbon Economy would be one which invests in new technology as well as in managing consumption. As a counterpoint to the heavy energy draining economies, a low-carbon economy would be one which creates jobs and resources in areas such as nuclear fission and fusion research[1].

Instead of using coal, natural gas and petroleum, it would focus on hydroelectricity, solar and wind power as well as harnessing the energy from the sea (both from wave energy as well as temperature differential) as well as other newer tech[2]. More than anything, a low-carbon economy would look at trying to achieve a life-cycle assessment for all power sources to come to as close to zero as possible[3].

Very different from a traditional economy, one would get rewarded for low-carbon choices and actions taken to reduce one's footprint. Some of the choices made in this scenario may not be comfortable, but it would be for the well-being of their children and their future generations.

Ideally, a low-carbon economy should aim to reduce carbon emissions in all areas of industry, while investing in cleaner technology which would reduce the burden on cost. Private industry can be given subsidies which are currently being given to coal and petroleum industry for lower carbon LCA alternatives[4].

Any economy which takes the leadership position in creating new technology automatically becomes a growth economy, and first movers can take this pole position. Early adopters also have an advantage in this scenario, as there may be niche areas in the alternate energy area and land management, management of mitigating strategies etc. which can be refined and developed.

Least attractive is the late adopters. Typically developed countries have been late adopters and other than the China story, the solar cell technology has benefited developed countries as far as technology leadership, patents and manufacture is concerned.

Technology is changing very rapidly now, and there are low-carbon alternatives in almost all areas. Growing more trees and creating rapid ability to harness water in the air along with creating alternate energy sources will be key to managing carbon emissions[5]. As mentioned before fusion and fission power is something we may need to use safely. A lot of the technologies exist today, while some vital technologies need a decade of work to see fruition[6].

Some of the basic ways we operate may change, but the idea is fundamentally change our consumption, while managing the change in such a way that we all have access to food, water, electricity, transport and communication, with managing the carbon emissions. Such an economy does not need to be a zero-growth economy, it just needs to have different values and systems. Growth would be measured in terms of reducing carbon emissions while also creating new jobs and opportunities in the alternate energy industry.

It may be impossible to exist in silos as we have done for so many years, and in some ways, the world is all in this together. It may be time to create a global governing body, especially with regards to climate change as this is probably the only way that countries will buy into, and participate in reducing their respective carbon emissions.

One of the other new research areas are how the microbiome affects climate[7]. This may be an area of opportunity in the future, and how we can understand and manipulate microorganisms around us, may be crucial to managing the climate. Every spoonful of dirt has millions of microorganisms, and what role they play in climate change is just starting to be researched.

The social and cultural ethos of such a society would be highly ethical and very measured. The populace would be highly educated in science and especially in the understanding of how the climate change can be managed. As such, it is more likely that such a society would voluntarily travel by public transport, plant trees and plants, practice rain water harvesting, using local produce, practice city and vertical farming[8], using LED lights, waste less food per person and use electricity sparingly. While it is not always possible to extrapolate such an economy, the drivers of such an economy would have to be very different from the consumerist and consumptive economies we have spawned today.

It is most likely that populations will continue to be concentrated in cities, but there is less need for people to travel and commute, which would make it a very different kind of life experience for people who live in our low-carbon economy.

Fusion news : I normally don't post about breaking news, but this one is interesting, and I'm cautiously optimistic. I owe this post to +Gary Ray R and +Aaron Coakley who commented on some other posts and on the new announcement from Lockheed at the Skunkworks facility.

Commentary from discussion on other posts :  Looking into the Skunkworks claim, it seems that they have a theoretical idea of the geometries, but they are still 5-10 years away from a working model. I do know they have some of the best engineers, and they take big risks, so I'm sanguine. I do hope they have something, since the ITER is dogged with delays and the Lawrence Livermore facility is scaling back. We do need some cutting edge engineers working on the problem. The theory is not the issue - its the engineering.

The theory is not the issue - its the engineering.

Fusion is the holy grail of our times. If someone does create a commercial system, it can change the whole issue with carbon emissions. Technically, fusion is possible even now, but bootstrapping and net gain are the issues, and as the LLNL folks found, its one thing to theoretically make assumptions of the engineering, and quite another to actually demonstrate it in the lab. Fusion is possible. Its just very hard to replicate what the Sun does!

From +Gary Ray R's research : "I did find the patent application for the new Lockheed Compact Fusion Reactor by the lead scientist at Lockheed, Thomas John Mcguire. There are drawings on the first 15 pages, description starts on page 16. http://www.freepatentsonline.com/20140301518.pdf." (Talks about the diagrams as well as the text of the patent). Btw if you're not following Gary you probably should!

From the Article: Most existing fusion devices slam together atoms using a tokamak, a magnetic device that contains the superheated plasma required for fusion to occur. The problem is, the energy required to sustain the reaction is almost as much as what's created by the reaction. Lockheed says they've figured out how to solve that problem, using their CFR, a jet-engine-sized device. They've changed the process for holding the plasma in a way they say has 10 times the output of a tokamak.They also say there's no risk of a meltdown, and that radioactive waste will be considerably lessened.

No prototype has been built or tested yet, though, and this research field is littered with failures, despite millions of dollars of investment.

Climate Change : Whether we like it or not, we are responsible for the increase in CO2 in the atmosphere. I've been trolled on an earlier post which was purely about the science of greenhouse gases. And this post is in response to that. Like a lot of people, I was uninformed about how exactly the science works. It's all about the retention of heat by the Earth. To know more, and to cut out the politics of the money behind the subject I enrolled in a course (https://class.coursera.org/climatechange-002 ). It seemed the logical thing to do. I asked the difficult questions and came back with some idea of the scope of the problem. 10 weeks of the lectures have given some idea of the issue.

I am not defending the science, too many naysayers have not even done their basic homework to polarize people into defensive attitudes rather than be able to make a logical and reasoned argument.... more »

I am not defending the science, too many naysayers have not even done their basic homework to polarize people into defensive attitudes rather than be able to make a logical and reasoned argument. Yes, we don't know everything, but science works in bits and pieces. We see evidence, make assumptions, test them without bias and try to achieve a hypothesis. I will keep this open to comments, but will disable the comments if there is any trolling.

Why it is important to you : I've heard people say that they are in a developed country and they do not need to worry about global warming. It is no surprise that people would be concerned only about their locality, but to be okay with millions dying worldwide is not 'cutting back on population', its far worse.

You may not be affected : This is the biggest lie which I've heard so far. Almost every single model predicts issues with the basic amenities like food, water, power and transport. And it will get progressively worse every year. Yes, life will get more and more difficult. With resources stretching thin, we will have less of everything and more hardship. Already both in the US and Australia, there are the worst drought in years in some regions. While scientists are very careful about pointing fingers, evidence shows that it is linked to the climate.

What can one expect? : Huge hardships in the future. And it gets exponentially worse every year. We already have climate change refugees. This is expected to get worse. Only over a period will we know the true scale of the effect, but all indications are it is going to get dire.

What can one do? : The good news is that we can still manage the effect. Slowing down on carbon emissions is the one main action one can take - use less fuel, switch off things when not needed, reduce wastage of food, practice rain water harvesting, try to find alternate energy sources, look at mitigation etc.  The slower the warming, the more likely it is to manage it's effects.

Size and flows : As Douglas Adams rightly said, Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. Lets take an example. The Milky way is our galaxy. When talking about space, a galaxy is well understood. It's made of millions of stars. The size? Around 100,000 light years in diameter. If we had a spaceship going at exactly light speed (if that was possible), we would not even be able to cross one-thousandth of the distance in a hundred years.

Now Scientists have theorized about the size and movement of the local galactic supercluster. How have they been able to estimate its movement? By means of a simulation of the gravity and flow and density which pulls over 100,000 galaxies together into what is called the 'Great Attractor.' The human mind can possibly not even comprehend the size. The boundaries of this supercluster are not very well... more »

Now Scientists have theorized about the size and movement of the local galactic supercluster. How have they been able to estimate its movement? By means of a simulation of the gravity and flow and density which pulls over 100,000 galaxies together into what is called the 'Great Attractor.' The human mind can possibly not even comprehend the size. The boundaries of this supercluster are not very well defined, and the flows are quite fascinating to watch. It takes me back to a post I made on flows (http://goo.gl/uho3rW) . At some stage, all the superclusters will be clumped into one. Maybe we will have a true idea of our Universe then!

+Knut Torgersen asked me to make this post... and here it is for your consumption. Though much has been said about the Laniakea Supercluster, this looks into the flows and size.

Cosmic Speed : The team used a database that compiles the velocities of thousands of galaxies, calculated after subtracting the average rate of cosmic expansion. “All these deviations are due to the gravitational pull galaxies feel around them, which comes from mass,” says Tully. The researchers used an algorithm to translate these velocities into a three-dimensional field of galaxy flow and density.

How did Brent Tully and his team do it? : If galaxies are clumped together closely in space they’ll orbit each other, or at least their mutual gravity will affect their motion. This in turn affects the redshift for each galaxy on top of the cosmic expansion. We know pretty well how the Universe is expanding on local scales, so if you subtract that part away, what’s left is the local motion of the galaxies. That can be used to map how gravity of other nearby galaxies is affecting them. This let them make a map of the density and movement of galaxies in space.

Size : The colossal supercluster is shown in the above computer-generated visualization, where green areas are rich with white-dot galaxies and white lines indicate motion towards the supercluster center. Galaxies flow into other galactic concentrations. The Laniakea Supercluster spans about 500 million light years and contains about 100,000 times the mass of our Milky Way Galaxy. The discoverers of Laniakea gave it a name that means "immense heaven" in Hawaiian.

What is the science behind climate change and global warming? : Someone recently asked me if a molecule with two atoms can be a green house gas. The simple answer is no, though some molecules may have an indirect effect on the greenhouse effect. The reason is simple. Molecules with only two atoms are closely bound to each other and the they cannot emit back heat in the IR range. Molecules which have more than two atoms, are bound much looser and can emit back the heat by vibrating. Here is a primer on the basic science behind greenhouse gases....

Molecules which have more than two atoms, are bound much looser and can emit back the heat by vibrating. Here is a primer on the basic science behind greenhouse gases....
 
Green House gases : Greenhouse gases (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would average about 33 °C colder.
 
The Carbon Cycle : Carbon reservoirs exchange carbon on a wide range of time scales from years (upper ocean, land biosphere) to millennia (deep ocean, deep soil. This time taken for CO2 concentration to relax back to an equilibrium can be from 5 to 1000 years.
 
Process of warming : Visible (short) wavelength radiation is absorbed by the Earth’s surface, which heats up. The Earth re-radiates mostly at infrared (long) wavelengths. This infrared radiation is absorbed by the molecules in the Earth’s atmosphere. The Earth’s atmosphere heats up, reradiates upwards AND downwards, further heating the Earth's surface.
 
Radiative forcing : The Earth absorbs some of the radiant energy received from the sun, reflects some of it as light and reflects or radiates the rest back to space as heat.[35] The Earth's surface temperature depends on this balance between incoming and outgoing energy.  A number of natural and man-made mechanisms can affect the global energy balance and force changes in the Earth's climate. Some greenhouse gases remain in the atmosphere for decades or even centuries, and therefore can affect the Earth's energy balance over a long time period.

Positive radiative forcing indicates warming (for example, by increasing incoming energy or decreasing the amount of energy that escapes to space), while negative forcing is associated with cooling.

Global Warming Potential : The global warming potential (GWP) depends on both the efficiency of the molecule as a greenhouse gas and its atmospheric lifetime. GWP is measured relative to the same mass of CO2 and evaluated for a specific timescale. Thus, if a gas has a high (positive) radiative forcing but also a short lifetime, it will have a large GWP on a 20-year scale but a small one on a 100-year scale. Conversely, if a molecule has a longer atmospheric lifetime than CO2 its GWP will increase with the timescale considered. Carbon dioxide is defined to have a GWP of 1 over all time periods.

Wind Turbines : Specifically the Altaeros Energies wind turbines from a startup which was spun off from MIT. The concept is very interesting. The downside is of course the use of Helium which is in short supply due to overuse by the security and airport agencies around the world.

Other alternate systems which use wind to generate electricity are Kitegen of Italy (earlier post here http://goo.gl/UkrLcC) and Makani Power (Purchased by Google) http://goo.gl/A3mSSx, both of which are under development. NASA continues to work on its own generating system (http://goo.gl/Fs1E8j). How much of a difference could it make? The LCA (Life cycle analysis) for these systems is hugely positive and in terms of costs, the economics can be as low as 20% of existing costs.

The LCA (Life cycle analysis) for these systems is hugely positive and in terms of costs, the economics can be as low as 20% of existing costs.

The BAT from Altaeros : Surrounded by a circular, 35-foot-long inflatable shell made of the same heavy-duty fabric used in blimps and sails, the BAT hovers 1,000 to 2,000 feet above ground, where winds blow five to eight times stronger, as well as more consistently, than winds at tower level. Conventional turbine construction requires tons of concrete and the use of cranes, which can be difficult to maneuver around certain sites. The modular BAT, Rein says, packs into two midsize shipping containers for transport "and can just be inflated out and self-lift into the air for installation."

Being cautious in implementing : Of course, floating tethered wind generators have their own set of safety issues. Something this big floating in the sky on wires could easily get in the way of small aircraft, or find itself coming down to earth in inconvenient ways if something goes wrong. Considering that there are many detractors to alternate energy, most companies are being extremely cautious in the prototype stage as well as coming out with a product too soon - since it would be disastrous to be labeled as an experiment which has failed or has issues. It will be at least a year before they are done with their testing protocols.

Read on to see the other benefits that could accrue...

The MIT CityFarm project : Harper's system promises to change the economics of industrial agriculture and to lessen its burden on the environment. By measuring and controlling light, moisture and nutrients, Harper says he can cut water consumption by 98 per cent compared to conventional agriculture; quadruple the growth speed of vegetables; completely eliminate chemical fertilisers and -pesticides; and double the nutrient density and flavour of his crops.

Energy and Yields : With grow racks rising 7.6 metres, Green Sense uses so-called hydronutrient film technology, allowing nutrient-rich water to trickle through pulverised coconut husk, rather than peat, because it's renewable. And as they are stacked vertically, not grown horizontally, Colangelo says the plants are at least ten times denser and can have 25 to 30 times more yield. "That's good for the Earth because there's no pesticide run-off and we have recycled water and recycled nutrients," says Colangelo, whose company has partnered with Philips to create what amounts to the biggest plant factory on the planet. "It uses a lot less energy."

Using our pollution : Their company, Zero Carbon Food (ZCF), will grow produce in vertical shelves, using an ebbandflood system: they will flood "benches" where the produce grows and let the nutrient-rich water ebb away. Plants will grow in a substrate of pulverised carpet, recycled from the Olympic Village in Stratford. To save energy and reduce the number of LED grow lights needed, ZCF will rotate them around the crops. And they will use electricity -- generated by small and portable microhydroelectric turbines -- to run the lights. "We have a lot of rain in London," says Dring. "You put these turbines in water drains and they feed into the energy grid." Dring will also harness one of the most pernicious problems of Tube travel: heat that collects in stations. "We are looking at pulling the heat out of the Tube stations and converting it into energy, as well as transferring the heat and the carbon dioxide into our grow rooms," Dring says, "which is like steroids for plants."

Tiny size but huge numbers : Each individual shrimp only generates the tiniest of currents, but when many shrimp swim in tandem, they generate a current that’s stronger than the sum of those created by each individual. When a larger group moves together, he says, they produce strong downward jets with swirling currents on the side says the study's author.

Physics : "This research suggests a remarkable and previously unobserved two-way coupling between the biology and the physics of the ocean," study researcher John Dabiri, a professor of aeronautics and bioengineering at the California Institute of Technology, said in a statement. "The organisms in the ocean appear to have the capacity to influence their environment by their collective swimming."

Influence : Usually, researchers credit the wind and tides for creating currents that mix the ocean's salt, nutrients and heat. In contrast, this study suggests that microscopic animals also influence currents. In a study published in 2009 in the journal Nature, Dabiri and his colleagues proposed that sea creatures such as jellyfish mix ocean waters, and ventured that even smaller organisms could do the same. This study offers evidence for their idea, at least in an aquarium environment.

The Bernal Sphere : While this is essentially a science fiction inspired mega project, which was proposed in 1929 by John D Bernal, the technology will soon be within our reach. Of course its a flight of fancy, but its interesting to read about, and makes for a great story. I do remember reading references in Arthur C Clarke's books as well as those by Peter F. Hamilton.

The Concept : A Bernal sphere is essentially a globe about a third of a mile in diameter that rotates almost twice per minute to provide Earthlike gravity along its equator. (This feeling of artificial gravity would peter out near the poles.) The vessel was essentially to be constructed from asteroid and Moon material, 16 km in diameter with a population of around 20,000 people. A atmosphere would be provided within the structure so that it became a self-contained habitat. The outer shell would be hard,... more »

The Concept : A Bernal sphere is essentially a globe about a third of a mile in diameter that rotates almost twice per minute to provide Earthlike gravity along its equator. (This feeling of artificial gravity would peter out near the poles.) The vessel was essentially to be constructed from asteroid and Moon material, 16 km in diameter with a population of around 20,000 people. A atmosphere would be provided within the structure so that it became a self-contained habitat. The outer shell would be hard, transparent and thin, preventing the escape of gas and allow for the preservation of a rigid structure. The Bernal sphere was mainly designed as a space habitat, but this visionary ideas laid the ground work for the more rigorous studies that were to follows. The American engineer Gerrard K.O’Neill took this work to a new level in the 1970s when he also designed large human habitat structures that could accommodate tens of thousands of people. O’Neill planned that such structures would be loaced at the L5 point in space, a region where the gravity from the Moon, Earth and Sun is neutral.

Mechanics : Gravity might be a thing of the past, everyone could drink distilled urine, and a whole generation of Earthlings may grow up without ever having set foot on the surface of the planet. At the moment, those ideas are still firmly set in the realm of science fiction, but in the next thousand years, new technologies could be developed that would enable humanity to colonize space. While a self-sustaining space station colony might be a long way off, scientists are still working to design and perhaps even build a space station that goes beyond low-Earth orbit.

Design your own : People from all walks of life can get involved in NASA's mission to create a sustainable deep space habitat, planners say. The space agency sponsors the eXploration Habitat (X-Hab) Academic Innovation Challenge for university students. The X-Hab competition asks students for ideas about the best ways to craft a space station that could exist for an indefinite amount of time in deep space. "One of the nice things about the X-Hab project is that we have been able to fund student work on a variety of habitat designs, which stimulates us and gives us ideas about ways to lay them out and innovative things to incorporate," Smitherman said.

Our Identity : I have often wondered what are we? What makes us tick. What makes it happen at the smallest and largest scale? We now have the ability to scan the smallest bits. And wonder. At the smallest scale, we are subatomic particles which behave in a very random fashion. Zoom out a little, and you notice we are atoms. The very building blocks of all matter. Most of the atom is nothing. It really is. Zoom out further and we are chemicals. The building blocks of organic materials. Zoom out further and we are cells. All kinds of specialized organic machines. We have already covered Physics, Chemistry and Biology at this stage. How is this put together? It is one of the biggest mysteries. At the macro level, we are organisms. Which act in a certain way based on all the tiny processes of the atoms, the chemicals and the biology.

Flows : Zoom out more and we notice we are governed by 'flow' everything flows of earth, the land, the seas, the air. Some scientists have postulated that the Universe itself is based on flow. Time flows, so do waves.... it makes one think. Combine this with the electromagnetic spectra, we have a mystery wrapped in a mystery.

At the Cosmological scale, we look at galactic clusters, at galaxies, at stars, at solar systems, at planets and at their attendant satellites. The mystery of dark matter and gravity eludes us yet. But we have good guesses.  

What is our identity? : Coming back to our original question, one doesn't really know. But we can lose ourselves in the voyage of discovery. That is the basis of the scientific method. To take tiny steps, to discover. To study how this works. Agreeing we don't know is the basis of the journey!

Urgently looking for some information / help : I am sending this post out for a  friend who is currently battling with cancer. I wanted to help, and ask our G+ community at large if there are people who understand how this works (preferably oncologists, radiologists and similar people in the field) and who might be able to guide me as to what are the therapies which are possible.

Of course I realize that this is not one disease, and therefore much more information needs to be shared (privately), but I am making a public post to appeal to people who have knowledge of the therapies, maybe are doctors and could help with clinical trials or guiding my friend in Europe of what can be done and how to go about it.

I am taking the liberty of notifying people who are close to me here. I apologize for this in advance.

I request you do not comment or derail the post if you are not of the above profile, though if you know someone who could assist, please tag them in. I also request you maintain confidentiality if you happen to know anything about the person in question. Thanks so much and thanks in advance.___

A Rose by any other name... : Roses are ubiquitous across the world. But there are actually over a 100 species and thousands of cultivars. Since Roses hybridize easily, it has led to a plethora of garden roses. But what is the science behind a rose?

Color Chemistry of Roses : Carotenoids produce the yellow colors, anthocyanins the reds, and a mixture of the two the modern oranges. But floral hues are products of more than pigment alone. A flower’s pigment resides within a watery cellular chamber known as a vacuole, and the environment of that vacuole differs from plant to plant. Its shape and acidity, the presence of metal ions or other pigments, and the arrangement of these various components—all affect the shade we see on a petal.

Its shape and acidity, the presence of metal ions or other pigments, and the arrangement of these various components—all affect the shade we see on a petal.

Perfumes : Rose perfumes are made from rose oil, which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. The main constituents of rose oil are the fragrant alcohols geraniol and l-citronellol and rose camphor, an odorless solid composed of alkanes, which separates from rose oil. β-Damascenone is also a significant contributor to the scent.

Physics of the flower : A Lily is described here...  Not content to just watch flowers dance in the breeze, Harvard physicists have described for the first time how flowers generate the forces needed to curl open come springtime. In the asiatic lily, this poetic blossoming is driven by skewed growth at the edges of petals. Over four and a half days, the asiatic lily’s young buds slowly suck up water, growing until they’re ready to explode. The petals and sepals — the outer, greener portion of a flower — gradually invert, then peel open like a banana and form a blossom.

Global Warming effects : Most roses in the U.S. and Europe are imported from warmer climes. All that flying and trucking adds thousands of metric tons of carbon dioxide to the atmosphere. Then there's all the water needed to, well, water the flowers. And the runoff fouled by copious quantities of pesticides needed to make the roses look perfect. There's also the wildlife and workers poisoned by all that fumigation. Add to that habitat destruction where floral plantations displace native forest and wetlands.

Medicinal uses : The fruit of a rose is called a rose hip. The berry-like hip are usually red in color but some can be dark purple or black. Rose hips of some species are extremely rich in vitamin C, because of this the hip is sometimes made into jam, jelly, or brewed for tea. The hip also has minor medicinal uses, used in food supplements and can be pressed or filtered to make rose hip syrup. Hip seed oil is also used in skin products and makeup products.

Still far away. Wish it was closer : The race for fusion is a long and arduous one. Time frames are in decades and funding, economics and politics all play a large part in how these progress.

Fusion : In principle, building a fusion reactor is just a matter of imitating the Sun. Take the appropriate isotopes of hydrogen or other light elements, add heat to strip the electrons from the nuclei and form an ionized plasma, then compress that plasma and hold it together for a while, allowing the nuclei to fuse and convert a portion of their mass into energy. But in practice, trying to mimic a star leads to horrendous engineering problems: for example, hot plasma trapped in a magnetic field tends to twist and turn like an enraged snake struggling to escape.

Tri Alpha : The world's most secretive nuclear-fusion company does not even have a website. Instead of using the doughnut-shaped 'tokamak' reactor that has dominated fusion-energy research for more than 40 years, Tri Alpha is testing a linear reactor that it claims will be smaller, simpler and cheaper — and will lead to commercial fusion power in little more than a decade.

ITER : Is now dogged by delays of funding and politics, its well beyond its deadline and delayed by a further 11 years. With over $50 Billion in funding and an open date, ITER may be delayed till 2050.

General Fusion : General Fusion has demonstrated the idea with a small-scale device, using pistons driven by explosives, and has raised about $50 million from venture capitalists and the Canadian government. If the company can win another $25 million or so, Laberge says, it will build a beefier implosion system that can compress the plasma to the levels needed for fusion — perhaps within the next two years. Despite such optimism, Dean estimates that it will be at least a decade, maybe a lot longer, before any alternative fusion company produces a working power plant. There is simply too much new technology to be demonstrated, he says. “I think these things are well motivated, and should be supported — but I don't think we're on the verge of a breakthrough.”

The flight of the humble Maple Seed : The maple seed is a single-winged spinning contraption. The way leading edge vortex behaves, it gives a motion which allows for the seed to disperse even if the wing is torn. This is not news, but I found it interesting. You may want to read how the seed's helical motion inspired a UAV.

Kinematics : maple seed falls in a characteristic helical motion. A crude analogy with autorotation of a wind turbine suggests that the torque due to the aerodynamic force would initiate the gyration of the seed. Researchers were therefore surprised that a seed with a torn wing gyrates in a similar manner as a full-winged seed. In fact, a seed with only a sliver of leading edge can still gyrate. Thus the gyrating motion appears not to fully depend on the aerodynamic force. If, on the other hand, the aerodynamic force is completely absent, a seed would fall... more »

Researchers were therefore surprised that a seed with a torn wing gyrates in a similar manner as a full-winged seed. In fact, a seed with only a sliver of leading edge can still gyrate. Thus the gyrating motion appears not to fully depend on the aerodynamic force. If, on the other hand, the aerodynamic force is completely absent, a seed would fall from rest like a rock in a vacuum.

How it works : There are three essential ingredients that lead to the observed helical motion seen in maple seeds. The first is the asymmetric mass distribution of the seed, with the centre of mass far away from the centroid of the seed. The second is the aerodynamic damping that initiates a tilt of the seed which eventually evolves into a helical motion due to the rigid-body dynamics. The third is the aerodynamic force in the steady state that balances the weight of the seed and the centrifugal force.

Monocopter with one wing : Researchers modeled the micro air vehicle (MAV) on a maple seed samara. Using a propeller, the Samara MAV spins itself in a circle around the end of the wing, creating lift that causes it to fly. Small changes to the pitch of the wing allow (the controller) to control where it goes.
 
Its all about dispersal : Many samaras are not capable of gliding or even efficient autorotation; however, simply being draggy is a huge adavantage. Distance traveled is equal to time times velocity, so for a given wind speed a slower-falling seed will spread further and thus be less likely to compete with its siblings for nutrients and water.

Today Mark Zuckerberg unveiled Facebook’s Connectivity Lab which will work on the Internet.org project. It’s powered by talent acqhired from solar-powered drone maker Ascenta as well as poached from NASA.

Internet.org, a partnership between Facebook and telecom industry giants like Nokia and Qualcomm, hopes to use these air- and space-born methods to bring Internet to the 5 billion people who currently lack it. Zuckerberg says that Internet.org and Facebook will work on inventing new technologies to complete the mission.

While they both have somewhat altruistic objectives, Facebook’s Connectivity Lab could compete with Google’s Project Loon, which uses huge helium balloon vessels to beam Internet to the developing world.

Why solar cell efficiency is by itself mostly meaningless : By itself, efficiency in solar cells is at best a secondary requirement when it comes to the effect that renewables have on the carbon emissions in the atmosphere. Why do I say this? Well what we do want to do is to have a full calculation in making a solar cell, its transportation, its use and its disposal to compare it with other alternates. Why is this important? It is very important, because high cost and high carbon equivalent production, transport and disposal (every emission is converted appropriately in equivalent carbon units) needs to be made to see if the overall energy used to make a solar cell (in its full life cycle) is less than the overall energy produced by the solar cell.

It is very important, because high cost and high carbon equivalent production, transport and disposal (every emission is converted appropriately in equivalent carbon units) needs to be made to see if the overall energy used to make a solar cell (in its full life cycle) is less than the overall energy produced by the solar cell.

What is OPV? : The pic shows a flexible Organic PhotoVoltaic cell sent to me by the DTU (Denmark Technical Univ.). It is a flexible organic, degradable solar cell which can be printed like a plastic sheet.

Life-cycle analysis : The push has been for doing a full life-cycle analysis of all solar cells. Right from the very high efficiencies (close to 30%) where the GWP or Global Warming Potential is quite high to the lower 3rd generation OPV efficiencies of close to 12% where the GWP is negligible. What does this mean? You can get a high efficiency solar panel, but the overall GWP may still be quite high. On the other hand, you may get a lower efficiency OPV solar panel, with a much lower GWP.

How long does it take solar cells to pay off its own production? : Solar panels are relatively quick to generate enough energy to offset the amount used in their own production, so they're considered to be quite efficient. The time it takes for solar panels to offset the energy used in their own production depends on how big the panels are, how much sunlight's available, and how efficiently the panels work. Typically the standard first generation monocrystalline solar cells have a payback period of 1.5 to 2.5 years. Solar panels are relatively quick to pay back the energy used in their production, and over the course of their lifespans generate many times this amount. Third generation OPVs have a much lower payback period of as low as 6 months.

Creation of power from solar cells is 'free' if area to be used in installing them is easily available. What one needs to look at is the total energy bill based on the LCA.

Article Extract: Plants are the undisputed champions of solar power. After billions of years of evolution, most of them operate at nearly 100 percent quantum efficiency, meaning that for every photon of sunlight a plant captures, it produces an equal number of electrons. Converting even a fraction of this into electricity would improve upon the efficiency seen with solar panels, which generally operate at efficiency levels between 12 and 17 percent.

Different from Potato cells : We've seen technologies where the electrons in the soil near plants' roots was are used to power a fuel cell and concepts for moss-powered lamps, but this discovery from University of Georgia researchers taps photosynthesis directly for producing electricity. During photosynthesis, plants use sunlight to split water molecules into hydrogen and oxygen, which produces electrons. Those electrons help create sugars that plants use to fuel growth and reproduction. "We have developed a way to interrupt photosynthesis so that we can capture the electrons before the plant uses them to make these sugars," said Ramaraja Ramasamy, assistant professor in the UGA College of Engineering.

The technology : technology involves separating out structures in the plant cell called thylakoids, which are responsible for capturing and storing energy from sunlight. Researchers manipulate the proteins contained in the thylakoids, interrupting the pathway along which electrons flow. These modified thylakoids are then immobilized on a specially designed backing of carbon nanotubes, cylindrical structures that are nearly 50,000 times finer than a human hair. The nanotubes act as an electrical conductor, capturing the electrons from the plant material and sending them along a wire.

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24 p.m. EDT Sunday, Sept. 21

On September 21, 2014 at 10:24 EDT, MAVEN was inserted into an areocentric elliptic orbit upon reaching Mars 6,200 km  (3,900 mi) by 150 km (93 mi) above the planet's surface. The principal investigator for the spacecraft is Bruce Jakosky of the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder.  ⓐ

“As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden. “It also will better inform a future mission to send humans to the Red Planet in the 2030s.”   ⓑ

EU Researchers look for alternate means of controlling pests : In an interesting article. some of the ideas are quite fascinating. Researchers are working on using sound, odor and other methods to reduce the amount of pesticides used. As of now, this is all under study and is not proven technology. But the ideas sound promising.

Article Extract: Scientists in Northern Italy are experimenting with unusual and totally eco-friendly sound and odor devices to fight off insects from their cultivated fields. And their studies suggest that these methods could be as efficient in protecting crops as using chemical based pesticides. In the meantime, in a field study near Pisa, Italy, researchers are learning how important it is to keep semi-natural habitats next to cultivated fields.

Article Extract: Scientists in Northern Italy are experimenting with unusual and totally eco-friendly sound and odor devices to fight off insects from their cultivated fields. And their studies suggest that these methods could be as efficient in protecting crops as using chemical based pesticides. In the meantime, in a field study near Pisa, Italy, researchers are learning how important it is to keep semi-natural habitats next to cultivated fields. These areas are an important resource for pollinators and it now seems they even have an impact on the yield of the cultivated crops.

In central Italy near Pisa scientists of the EU research project QuESSA want to understand how the land next to the cultivated fields – known as semi-natural habitats – may help to maximize the harvest. Camilla Moonen and her team focus on natural pollinators like the wild bee. In experiments they are investigating, whether natural pollinators contribute a higher yield quality. Both of these studies have shown that modern agriculture can still learn from nature and secure a successful harvest and reduce the usage of chemicals at the same time.

Split ring resonators (SRR) : Refractive index of a material is vital in understanding how light propagates through the material. Refractive index 'n' is n=  sqare root of εμ. Where ε is the permittivity and μ is the permeability. for transparent materials, both these values are greater than zero. For metals, ε < 0 which is why metals are opaque to visible light.

Negative refractive Index : A material which has ε < 0 and μ < 0, is one in which the refractive index would be 'real' i.e. not imaginary. But a negative μ implies a negative refractive index ! This never happens in natural materials. But a metamaterial could be engineered in which we have sub-wavelength elements with just such properties.

Nanostructures : Since light is part of the electromagnetic spectrum, a split-ring resonator can act just like a LC circuit and display properties of a resonator. Another aspect of unnatural electromagnetic wave propagation can be observed at the contact surface between two different materials, where one of them is electromagnetic metamaterial. Negative refraction breaks light waves reverse to what the standard physics postulates. Effects such as the one seen in the figure showing refraction (the wrong way!) this can be achieved with appropriately designed metamaterials.

Invisibility Cloaks : What SRR do is refract light at an angle which is analogous to chiral. The basic idea is to create an artificial crystal with significantly sub-wavelength periods. However, it has only been done for microwaves, since the wavelengths of visible light are small. Theoretically, it should be possible.

Why did the scramjet not take off? : Its been a long haul for the scramjet. The technology has existed since the 1950s, but since Budget cuts and politics (and rocket tech) came along, scramjets were relegated to a 'also ran' program. Why is it an idea one would want? The cost per launch using a railgun cum scramjet or air to air launch would be many orders of magnitude less than conventional rocket technology. Unfortunately, the testing of these has been dogged by failure and budget cuts...

Disappointment : Until the last few years, the scramjet had an unbroken history of disappointment. Budget cuts killed the program in 1993. Its shape, however, lived on in two small test vehicles, the NASA X-43 and U.S. Air Force X-51, which have managed a few seconds of scramjet flight.

Disappointment : Until the last few years, the scramjet had an unbroken history of disappointment. Budget cuts killed the program in 1993. Its shape, however, lived on in two small test vehicles, the NASA X-43 and U.S. Air Force X-51, which have managed a few seconds of scramjet flight.

Sweet spot : “If you fly too low, there’s a lot of air density friction and the aircraft gets too hot,” said Goyne. “Too high, you start to run out of oxygen. The sweet spot altitude is 100,000 ft. or so.” Goyne says one of the key advantages of a scramjet over a rocket engine is that the scramjet gets the oxidizer to combust its fuel from the air it is flying through, whereas a rocket engine needs to carry liquid oxygen to burn its liquid hydrogen fuel.

Foray into railgun cum scramjets : In April, President Obama urged NASA to come up with, among other things, a less expensive method than conventional rocketry for launching spacecraft. By September, the agency’s engineers floated a plan that would save millions of dollars in propellant, improve astronaut safety, and allow for more frequent flights. All it will take is two miles of train track, an airplane that can fly at 10 times the speed of sound, and a jolt of electricity big enough to light a small town. The system calls for a two-mile long rail gun that will launch a scramjet, which will then fly to 200,000 feet. The scramjet will then fire a payload into orbit and return to Earth. The process is more complex than a rocket launch, but engineers say it’s also more flexible. With it, NASA could orbit a 10,000-pound satellite one day and send a manned ship toward the moon the next, on a fraction of the propellant used by today’s rockets.

Politics : So what really happened to ramjets? Sputnik and Robert McNamara. The space race diverted U.S. space science into rocketry, and President John Kennedy’s defense secretary and his whiz-kid advisors backed intercontinental ballistic missiles over air-breathers, expecting the latter to be easily shot down by bigger enemy missiles.

Coffee has larger families of genes related to alkaloid and flavonoid compound production than other plants. This contributes to the aroma and bitterness of the beans. There are 23 new genes found exclusively in coffee. They are different than the caffeine-related genes in chocolate, indicating that the ability to produce caffeine evolved at least twice.

How important is coffee? : More than 2.25 billion cups of coffee are consumed every day. The plant is grown on more than 11 million hectares, often in developing countries where it is an important cash crop. "Many people argue it's the most traded commodity after oil," says molecular biologist Professor Robert Henry.

Coffee anyone? : The enzymes and biochemical pathway for producing caffeine in coffee are different to those in tea or cacao plants. "The interesting thing is that caffeine synthesis has evolved separately in each of the three plants," says Henry. "It's convergent evolution."

"Clearly caffeine is a particularly well-designed or biologically effective molecule if it has evolved independently at least three times," he adds. Henry says caffeine is involved in the plant's defences. "Its bitterness might serve as a warning against some predators," he says. The researchers also found genes for disease resistance, and genes for linoleic acid, which play a key role in aroma and flavour of coffee.

My design for creating water from air (and creating excess power while at it) : While some companies have entered this space, the idea is actually pretty simple. If we can harness electricity through both solar and wind power, one can ostensibly create excess energy. This can be used to power a condenser in even the driest areas.

OPV Cells: Are organic photovoltaic cells. These are solar cells with a proven commercial efficiency of around 6-9%. While this is not much, it could easily be used to create a temperature differential through the condensation coil. The advantage is they are flexible and can be wrapped around the tower (solar paint and OPV post - http://goo.gl/FV3J81)

Wind Turbine : Wind turbines are very old technology. The wind turbine shown here will create excess power, which can be used to pay for the construction of the whole system over time. (Post on wind turbine hybrid here http://goo.gl/9USdjE)

Air cycle : As warm air is pulled in and expelled from the top, it would create condensation, for which a collector could be built at the bottom of the chamber (not shown). If drinking water is required, additional filters can be used to remove impurities and organic materials. (See Wind funnel: http://goo.gl/1IbrHF)

Condenser coils : Very much like your air conditioner or refrigerator, condenser coils are cold. Newer tech can be used to create magnetic condenser coils which are more efficient. (Link to condensation: http://en.wikipedia.org/wiki/Atmospheric_water_generator)

Power conversion and on-grid supply : The towers can be connected to the grid. That would ensure that there is no waste energy. As explained earlier, if we also harness the temperature differential to create electricity, it would become a very efficient system.

Simulated Brains and the Boltzmann Brain Hypothesis : While reading about the Human Brain Project and the U.S. parallel project called the BRAIN initiative, I came upon the Boltzmann Brain Hypothesis. Combining quantum probabilities with something emerging out of chaos. Sounds crazy? I'm very skeptical, but the physics allows it. Does not mean there are space brains floating around, but it makes for an interesting thought. Read for yourself...

Is a simulated brain conscious? : Notwithstanding what Watson can do, it is not an artificial intelligence. But think of this... Imagine standing in an open field with a bucket of water balloons and a couple of friends. You've decided to play a game called "Mind." Each of you has your own set of rules. Maybe Molly will throw a water balloon at Bob whenever you throw a water balloon at Molly. Maybe Bob will splash both of you.... more »

Is a simulated brain conscious? : Notwithstanding what Watson can do, it is not an artificial intelligence. But think of this... Imagine standing in an open field with a bucket of water balloons and a couple of friends. You've decided to play a game called "Mind." Each of you has your own set of rules. Maybe Molly will throw a water balloon at Bob whenever you throw a water balloon at Molly. Maybe Bob will splash both of you. The details don't matter. That game would look a lot like the way neurons, the cells that make up your brain and nerves, interact with one another. They sit around inside an ant or a bird or Stephen Hawking and follow a simple set of rules. Sometimes they send electrochemical signals to their neighbors. Sometimes they don't. No single neuron "understands” the whole system.

Now imagine that instead of three of of you in that field there were 86 billion -- about the number of neurons in an average brain. And imagine that instead of playing by rules you made up, you each carried an instruction manual written by the best neuroscientists and computer scientists of the day -- a perfect model of a human brain. No one would need the entire rulebook, just enough to know their job. If the lot of you stood around, laughing and playing by the rules whenever the rulebook told you, given enough time you could model one or two seconds of human thought.

Boltzmann Brains : The weirdness gets even weirder when you consider that according to many theorists, not all the possible minds in the universe are biological or mechanical. In fact, under this interpretation the vast majority of minds look nothing like anything you or I will ever encounter. Here's how it works: Quantum physics -- the 20th century branch of science that reveals the hidden, exotic behavior of the particles that make up everything -- states that nothing is absolute. An unobserved electron isn't at any one point in space, really, but spread across the entire universe as a probability distribution; the vast majority of that probability is concentrated in a tight orbit around an atom, but not all of it. This still works as you go up in scale. But the probability in 'empty space' is not zero.

As eons pass and the stars burn themselves out and the universe gets far emptier than it is today, that quantum randomness becomes very important. It's probable that the silent vacuum of space will be mostly empty. But every once in a while, clumps of matter will come together and dissipate in the infinite randomness. And that means, or so the prediction goes, that every once in a while those clumps will arrange themselves in such a way perfect, precise way that they jolt into thinking, maybe just for a moment, but long enough to ask, "What am I?"

These are the Boltzmann Brains, named after the nineteenth-century physicist Ludwig Boltzmann. These strange late-universe beings will, according to one line of thinking, eventually outnumber every human, otter, alien and android who ever lived or ever will live. In fact, assuming this hypothesis is true, you, dear reader, probably are a Boltzmann Brain yourself. After all, there will only ever be one "real' version of you. But Boltzmann Brains popping into being while hallucinating this moment in your life -- along with your entire memory and experiences -- they will keep going and going, appearing and disappearing forever in the void.

Metamorphosis : The Science of the changing body plan. Metamorphosis is a change in the body structure of organisms (usually rapid) involving cell growth and differentiation. It is fascinating to study and even more so to see it in action. The process is quite gruesome, and there is a good reason why very small kids are not told how a caterpillar transforms into a butterfly. The primary role of metamorphosis seems to be to have a different ecological niche for larval forms and adults. It may all be about survival....

Caterpillars; the inside story : If you look inside a caterpillar you won't see a butterfly all rolled up waiting to emerge. You'll just see more caterpillar and some well-chewed leaves. But with a decent microscope and some excellent navigation skills you might glimpse some tiny disc-shaped bags of cells here and there. They're called imaginal discs, and once the caterpillar silks itself up in a chrysalis they kick into action, each one of them growing into an antenna, eye, wing or other butterfly bit.

Eating it's own tissue : During the week or two spent in its chrysalis (pupation) the caterpillar gradually digests all of its own tissue, releasing the nutrients that all those imaginal discs then use to grow into butterfly wings, legs, feelers and the rest. It's the ultimate in recycling makeovers, and it's due to some interdependent hormonal changes that make puberty look like a doddle.

Hormones control the process : The thing that drives caterpillars (and other flying insect larvae) to stop feeding their faces, settle down somewhere safe, and pupate, is the hormone ecdysone. It's the same hormone that causes the larvae to moult each time they outgrow their current skin. The reason this final moult into a butterfly is so different from the earlier ones is because the level of another hormone; juvenile hormone; is suddenly lower.

Juvenile hormone is the great controller of metamorphosis, by delaying it until the caterpillar has moulted and grown enough to produce a decent-sized butterfly. It works by blocking the genes in the imaginal discs, keeping those wannabe butterfly cells in a holding pattern. So while juvenile hormone is being pumped out of tiny glands behind the brain, all the caterpillar can do is feed, grow and — when instructed by ecdysone — moult. (It's so good at preventing larvae from maturing that a lot of insecticides have been based on artificial juvenile hormone).

A complete makeover : Butterflies are pretty and all, but that's not the only pay-off for all that metamorphic effort. Butterflies and caterpillars don't just look different; they've got different ideas of what constitutes food and accommodation. While caterpillars live off leaves and are plant-bound, those butterflies that do feed only drink nectar, and they can fly from place to place looking for love and somewhere to lay the progeny. Those fundamental differences mean the adults don't compete with the juveniles for food or habitat, so the species has a better shot at making it. Which probably goes a long way towards explaining why more than half the animal species on the planet are insects that undergo the same kind of complete metamorphosis. As far as evolutionary strategies go, it's gold. And come mating time it doesn't hurt that the adults are almost always better lookers than all those larvae that only a mother could love.

Solar paint : Organic Photovoltaics (OPV) has paved the way to flexible solar cells using roll-to-roll technology. The next step is to spray it on any surface. Challenges still exist of degradation, efficiency and thin-film transparent coatings. But cutting edge technology on OPV is breaking new ground everyday. Will we soon see solar paint which can be sprayed on your roof, walls and cars? It's some time away, but rapid strides are being made in the chemistry at the nano level. And I'm sanguine.

OPVs : Conventional photovoltaic technology uses large, heavy, opaque, dark silicon panels while  organic photovoltaic technology enables more translucent and more flexible cells. OPVs need have greater efficiency, longer duration and low production cost - or at least some combination of those. Legacy solar panels have not improved in decades.

OPVs : Conventional photovoltaic technology uses large, heavy, opaque, dark silicon panels while  organic photovoltaic technology enables more translucent and more flexible cells. OPVs need have greater efficiency, longer duration and low production cost - or at least some combination of those. Legacy solar panels have not improved in decades.

Solar paint is close : Scientists have dreamed of painting solar cells to generate energy on just about any surface, but efficiency has been a problem; researchers were happy to get one percent just a couple of years ago. At last, though, it looks like viable paint-on power is close at hand. A team at the University of Sheffield has developed spray-on cells that should be both cheap and capable. The trick is to coat an object in perovskite, a calcium titanium oxide mineral -- it's inexpensive like organic solar cells, but absorbs light nearly as well as silicon. In the lab, the technology isn't quite ready for prime time. A spray-based cell gets about 11 percent efficiency versus 19 percent at perovskite's ideal performance. However, it's still early days. Scientists believe that their approach could scale up to the same manufacturing techniques used for spray painting vehicles. If that happens, it's conceivable that your future car (and virtually any other device) could harvest the sun's rays without the steep costs and awkward product designs that are frequently involved when you use old-fashioned solar panels.

Hybrid tech : The invention involves the development of a completely printable organic solar cell based on semiconducting polymer nanoparticles dispersed in water. Essentially these tiny particles in suspension are a water-based paint, which can be printed or coated over large areas. In the first instance these coatings will be put onto plastic sheets that can be placed on the roof of a house. However, in the longer term it will be possible to directly paint a roof or building surface.

Article Extract : Google Earth Engine is an incredible satellite tour through the recent history of our planet, showing year-by-year images from 1984-2012. Watch as cities expand, glaciers retreat, and seas vanish in a matter of decades.

Google Earth Engine uses composites of annual Landsat images to create these amazing views of how the world has changed over the last 28 years. Google offers a handful of suggested time travel destinations, but you can look up any place you like—your hometown, places that have endured natural disasters, places that have been altered by human hands and by nature.

Time-lapse Earth is powerful because it helps us to access and construct the story of our planet. That story will become richer with each release, as we continue to improve fidelity and add data. The story-teller is everyone — scientists and citizens alike provide the real value by interacting, exploring, layering their knowledge upon the globe, and sharing their insights so that we can all better understand our world.

The Ringworld concept in SF : Larry Niven dreamt up this megastructure based on the fact that Dyson spheres had two drawbacks. One was that it could not possibly have the same gravity everywhere due to the centrifugal force being concentrated around the 'equator' of the sphere. Niven's solution? Get rid of the sphere and just keep the equator. While the science is still not verified and the concept may well be in the realm of impossibility, it makes for great story telling.

Megastructure : Sci-fi author Larry Niven conjured up such a megastructure for his award-winning 1970 book Ringworld. Niven imagined a ring with a radius of 93 million miles—the sun-Earth distance—with the sun placed at the center. The ring' would reach 600 million miles across and a million miles tall.

Megastructure : Sci-fi author Larry Niven conjured up such a megastructure for his award-winning 1970 book Ringworld. Niven imagined a ring with a radius of 93 million miles—the sun-Earth distance—with the sun placed at the center. The ring' would reach 600 million miles across and a million miles tall. The vast landscape could comfortably support perhaps trillions of humans (or another similarly ambitious, technologically advanced race).

Huge scale : Niven figured a Ringworld would have a thickness of a few thousand feet, and require raw materials with a mass equal to that of Jupiter. Mountain "walls" a thousand miles high would line each rim, preventing the atmosphere from leaking into space.

Viability : Could a Ringworld ever be made? While the concept does not bend physics past the point of breaking, it would require truly extreme engineering and an utter mastery of the forces of nature. According to Anders Sandberg, a research fellow at Oxford University's Future of Humanity Institute who has studied megastructure concepts, a Ringworld "is an amazingly large structure that's way beyond what we can normally imagine, but it's also deeply problematic."

Issues : To get Earth-like gravity, the Ringworld would need to spin at nearly three million miles per hour. Very fast, to be sure. But in a frictionless space environment, it could be doable. Although it would be equidistant from its central star at all points, the Ringworld would not, in fact, be gravitationally stable. Any perturbing force from, say, a meteorite strike or a close encounter with another star could throw the Ringworld out of attractive equilibrium and onto on a cataclysmic collision course.For residents of the Ringworld, that sun would always be directly overhead at a perpetual high noon. To create a day–night cycle and save plant life from frying, Niven envisioned a set of "shadow squares" around the sun at about Mercury's distance from Earth. The parts of Ringworld between the squares would experience roving daylight, while the eclipsed portions would rest in the shade. The whole length of the Ringworld would be checkered light and dark. Solar panels on the immense shadows squares could collect energy to power the structure. Energy could be beamed via laser from the squares to receiver stations along the Ringworld's rim, away from inhabited "land."

Movement : Cavagna was hardly the first scientist to be intrigued by these acrobatics—known, in a rare instance of technical language coinciding with poetry, as “murmurations.” Other animals that travel in groups showing the same uncanny ability to move in apparent unison away from a predator or toward a food source. One 20th-century ornithologist seriously proposed that they coordinated their movements by telepathy. That possibility hasn’t found much support in biology. The other explanation is that a signal to change direction originates with one or a few individuals, probably on the periphery (the ones most likely to see a threat), and travels as a wave front across the flock, like a ripple spreading across a pond from a dropped pebble. It is just an artifact of human vision that we can’t see it happen in real time. But high-speed cameras can capture it, and computers can model the behavior.

Swarm faster than individuals : Prince­ton biologist Iain Couzin and MIT oceanographer Nicholas Makris have shown that in the presence of a predator, or a potential food source, or an opportunity to spawn, a wave of movement crosses a school of fish five to ten times faster than any one of them can swim—“incredibly well orchestrated,” says Couzin, “like a ballet.” The fish they’ve studied exhibit a threshold response, changing course only when a sufficiently large fraction of their visible neighbors have.

Wave Phenomena : As for starlings, Cavagna and his collaborators have shown recently that each keeps track of the six or seven closest starlings, adjusting its flight to stay in synchrony. In a new paper, they show how a signal originating with a single individual can cross a hundred-yard-wide flock in a fraction of a second, with virtually no distortion or diminution. The equations that describe this are those that govern waves—rather than, say, the diffusion of a gas or liquid. In the broadest sense, the same laws that photons obey are in play when a flock of starlings encounters a peregrine falcon.

Article Extract: The Rosetta spacecraft has captured remarkable views of the comet on its way into orbit. Images of the comet revealed that Comet 67P/C-G is actually two connected pieces hurtling through space together. The smaller "head" and larger "body" of the comet are connected by a bright "neck," as seen in photos of the comet taken by Rosetta.

ESA has announced that on September 15, the team from the Rosetta mission will reveal the landing site for the Philae lander. After traveling on a 10-year, 6.4 billion kilometer journey, Rosetta has been gently captured by comet 67P/Churyumov-Gerasimenko, an oddly-shaped and mysterious two-lobed comet. Yet, how will the small Philea attempt the landing? Very carefully, because a second chance is not possible. Philae cannot pull up and try again.

The landing mechanisms are: landing legs with ice screws, propulsion system and harpoons. The legs were designed with the intent of landing softly. The harpoons are designed to secure Philae to the surface. The gravity of the comet is so weak, Philae could bounce off the surface or roll over. The purpose of the harpoons — to be fired at the moment of contact — is to prevent bouncing off the surface or tipping over. The direction and strength of gravity at the landing site will not be absolutely known so there is the risk of roll over after landing, albeit very slowly. Tipping over is mitigated by screws under the footpads to penetrate the surface immediately after landing.

"We're going to going to ride along with this comet. We're going to have a ringside seat," Matt Taylor, ESA Rosetta project scientist, said Wednesday as the spacecraft arrived at Comet 67P/C-G. "It's going to be an awesome ride. Stay tuned."

Carbon in the soil : There are 2,500 billion tons of carbon in soil, compared with 800 billion tons in the atmosphere and 560 billion tons in plant and animal life. And compared to many proposed geoengineering fixes, storing carbon in soil is simple: It’s a matter of returning carbon where it belongs.

How the soil loses carbon : "If we treat soil carbon as a renewable resource, we can change the dynamics," says Goreau. "When we have erosion, we lose soil, which carries with it organic carbon, into waterways. When soil is exposed, it oxidizes, essentially burning the soil carbon. We can take an alternate trajectory."

Microbes play a huge role : As basic as soil carbon is, there’s much scientists are just learning about it. One promising strategy, says Goreau, is bolstering soil microbiology by adding beneficial microbes to stimulate the soil cycles where they have been interrupted by use of insecticides, herbicides, or fertilizers.

Plants also move Carbon into the soil : Plants with mycorrhizal connections can transfer up to 15 percent more carbon to soil than their non-mycorrhizal counterparts. The most common mycorrhizal fungi are marked by threadlike filaments called hyphae that extend the reach of a plant, increasing access to nutrients and water. These hyphae are coated with a sticky substance called glomalin, discovered only in 1996, which is instrumental in soil structure and carbon storage.

A gentler way of going about carbon sequestration : Absent carbon and critical microbes, soil becomes mere dirt, a process of deterioration that’s been rampant around the globe. Many scientists say that regenerative agricultural practices can turn back the carbon clock, reducing atmospheric CO2 while also boosting soil productivity and increasing resilience to floods and drought. Such regenerative techniques include planting fields year-round in crops or other cover, and agroforestry that combines crops, trees, and animal husbandry. Recognition of the vital role played by soil carbon could mark an important if subtle shift in the discussion about global warming, which has been heavily focused on curbing emissions of fossil fuels. But a look at soil brings a sharper focus on potential carbon sinks. Reducing emissions is crucial, but soil carbon sequestration needs to be part of the picture as well, says Lal. The top priorities, he says, are restoring degraded and eroded lands, as well as avoiding deforestation and the farming of peatlands, which are a major reservoir of carbon and are easily decomposed upon drainage and cultivation.

Storing Carbon in Deserts : Even at our current level of knowledge, many see great potential for storing carbon in soil. Lal of Ohio State says that restoring soils of degraded and desertified ecosystems has the potential to store in world soils an additional 1 billion to 3 billion tons of carbon annually, equivalent to roughly 3.5 billion to 11 billion tons of CO2 emissions. (Annual CO2 emissions from fossil fuel burning are roughly 32 billion tons.)

Flight of the Falcon ....... no, the Robohawk? : This clumsy title was what I actually thought when watching the video. Clear Flight Solutions has created a robotic bird to scare off other birds especially around airports. I was a little taken aback at how realistic it is, using wing deformation to glide, just like a real bird.

The genesis : Nijenhuis is a student of applied physics and fluid dynamics at the Technical University of Twente in the Netherlands. When wings are fixed, we're fine. We can run tests and calculate forces and as a result have been able to develop planes that take us all over the globe. "But the minute wings start moving, we really have a problem," Nijenhuis says. "It's all about very complex, three-dimensional flow. What a bird actually does is so complex that it's incredibly difficult to mimic."

Flight of the Falcon ....... no, the Robohawk? : This clumsy title was what I actually thought when watching the video. Clear Flight Solutions has created a robotic bird to scare off other birds especially around airports.

The genesis : Nijenhuis is a student of applied physics and fluid dynamics at the Technical University of Twente in the Netherlands. When wings are fixed, we're fine. We can run tests and calculate forces and as a result have been able to develop planes that take us all over the globe. "But the minute wings start moving, we really have a problem," Nijenhuis says. "It's all about very complex, three-dimensional flow. What a bird actually does is so complex that it's incredibly difficult to mimic."

Creating the Robohawk : The big concept ended up being flexibility. Instead of just flapping from one joint like a rigid two-by-four, bird wings deform across their entire length as they move through the air. For the Robirds, Nijenhuis complemented the basic hinging motion with a pitching motion on the wing tips -- the further outward you go, the more the heavy-duty foam wings deform upwards and downwards. The result, when paired with some on-board sensors and sophisticated stabilisation software, is a fairly convincing approximation of bird flight.

Why is it important to fly like a bird : Getting close to the mark is important for the Robirds to do their job. Nijenhuis says two things are needed to trigger birds' flight instinct: a silhouette and wing movement. "If it doesn't look like a predator, they don't care. And if it doesn't move like a predator, they don't care either."

In the clip, notice from 1:55 onward as the penguins swim for the surface and leap onto the ice - they leave a trail of bubbles in their wake. The penguins are using supercavitation to decrease their drag. When the penguins first dive in to the water, they splay their feathers out in the air and then lock them closed in the water, trapping pockets of air beneath them. When the need for a burst of speed arises, the penguin shifts its feathers to release the air, coating most of its body in a layer of bubbles. Because the drag in air is much less than the drag in water, this enables the bird to achieve much higher speeds than they normally do when swimming.

Rocketing speeds : Essentially, the air buffer means that the majority of the body of the penguin isn't in the water at all, but rather cruising inside an air bubble with just the head and fins protruding to allow for maneuvering. Since the drag between air and water is far less than the drag between penguin and water, for all practical purposes the penguins get to totally ignore the fact that they're swimming and, while they still have enough air stored in their feathers to maintain the bubble, pretend like they're flying instead, which is how they can put on those rocket-like bursts of speed. Penguins would only be able to reach four or nine feet per second otherwise, but they can triple double or triple those speeds with their special bubble boost.

China's attempt at creating a supercavitating submarine : The submarine of the future may come to America in a super fast bubble, traveling under water. Researchers at China's Harbin Institute of Technology developed a new concept for submarine “supercavitation,” where an underwater vessel creates a pocket of air around itself. Inside this bubble, the submarine can travel much faster without friction of water creating drag and slowing it down. Theoretically, a supercavitated vessel using rocket engines could travel inside that air pocket at almost the speed of sound.

Flying Snails : No not really. But this is a kind of an amusing story. It all started with Charles Darwin, who was fascinated that how very similar snails were found on diverse land masses. It was hypothesized that snails stick to birds. Some snails managed to hitch rides on logs or other floating items. But some snails have a slightly different method of travelling. Read on to know more.

Horn snails : The horn snails found their own life rafts: shore birds. Although the research group can't prove that the scenario is true, they think it could have gone like this: Nearly 1 million years ago, a wading heron gobbled a basking Pacific horn snail, shell and all. Luckily for this intrepid explorer, armored invertebrates can survive for days in the bellies of shore birds. Snug inside its unsuspecting taxi, the snail soared high above what was likely Mexico before being excreted in the... more »

Luckily for this intrepid explorer, armored invertebrates can survive for days in the bellies of shore birds. Snug inside its unsuspecting taxi, the snail soared high above what was likely Mexico before being excreted in the Atlantic Ocean—a journey of about 200 kilometers or more. (From Sciencemag : http://goo.gl/FdHW7a)

Tough travellers : If a bird takes flight and keeps aloft for all five hours, a snail could be transported as far as 186 miles away. Should the snails take hold in their new homes, and should ducks sample the new population of gastropods, the snails could be dispersed even further still. Why the one species of snail was able to survive while the other three perished is not immediately clear. But van Leeuwen and co-authors suspect that the pre-existing adaptations of Hydrobia ulvae were key. The strong shell and other traits possessed by the snail species – thought to be defenses against predation and drying out when exposed – may better protect these snails from being crushed or killed by enzymes in duck digestive tracts. The snails just happened to have a suite of traits which allowed them to survive the internal journey. (From +WIRED : http://goo.gl/qHK6Z3)

Globetrotters : Plants and sedentary animals have long travelled great distances thanks to water, wind, or hitching a ride on other, more mobile animals. But the enormous distances travelled by these snails more commonly occurs in the plant than in the animal kingdom. Preece is now trying to collect molecular data as further evidence of globetrotting in these snails, beyond the Atlantic region. He points out that past research has also shown the creatures doing some mountaineering: they were found on a remote mountain peak on Madeira Island, Portugal, back in 1921. "They get around the world," says Preece. (From +Nature Publishing Group : http://goo.gl/CrLuZu)

Sources on the internet : I often link to basic information on topics to Wikipedia. And one needs to know how good the information is. Wikipedia has actually improved over time, and basic information is something which now pretty well edited and usually cited. Though more esoteric information and not very well-known topics are either not well cited or sketchy. Can you trust Wikipedia? Well depends on what you are looking for and how specialized the information is....

Basic Reference : The fact that Wikipedia is not a reliable source for academic research doesn't mean that it's wrong to use basic reference materials when you're trying to familiarize yourself with a topic. In fact, the library is stocked with introductory materials, and the Harvard librarians can point you to specialized encyclopedias in different fields.

Basic Reference : The fact that Wikipedia is not a reliable source for academic research doesn't mean that it's wrong to use basic reference materials when you're trying to familiarize yourself with a topic. In fact, the library is stocked with introductory materials, and the Harvard librarians can point you to specialized encyclopedias in different fields. These sources can be particularly useful when you need background information or context for a topic you're writing about. (http://goo.gl/UDPHmJ - From +Harvard University).

Universities and researchers are also involved in edits : While experienced editors can view the article history and discussion page, for normal users it is not so easy to check whether information from Wikipedia is reliable. University projects from California, Switzerland and Germany try to improve that by methods of formal analysis and data mining. A new journalism class at American University, “Wikipedia and Public Knowledge,” is organized around edit-a-thons, held each Tuesday at a prominent institution in Washington, including the National Archives and the National Museum of the American Indian. The 20 students in the class are expected to create or improve articles on Wikipedia and scan in and describe documents or images. (From NYT http://goo.gl/c4AaR6) and

Typical Issues : In only 10 years, Wikipedia has risen from obscurity to become the dominant information source for an entire generation. However, any visitor can edit any page on Wikipedia, which hardly fosters confidence in its accuracy. In this article, I review thousands of Wikipedia articles about candidates, elections, and officeholders to assess both the accuracy and the thoroughness of Wikipedia's coverage. I find that Wikipedia is almost always accurate when a relevant article exists, but errors of omission are extremely frequent. These errors of omission follow a predictable pattern. Wikipedia's political coverage is often very good for recent or prominent topics but is lacking on older or more obscure topics. (Quote from a Political scientist - http://goo.gl/IFOT4k)
