Science on Google+401,137Please join us for Developmental Science HOA, a new collaborative Hangout On Air series which is co-hosted by +Science on Google+ and +Developmental Psychology. In the first Developmental Science HOA we will be talking with Dr. +Gedeon Deák. +Gedeon Deák is a Professor of Cognitive Science and Human Development at +University of California, San Diego and is the director of the +Cognitive Development Laboratory at UC-San Diego. +Gedeon Deák studies the dynamics of infant social interactions and social learning, using experimental behavioral paradigms, ethnographic investigations, physiological studies, and computer simulations. He and his collaborators conducted the first study of real-time interactions between parents and toddlers with high-density EEG and motion capture of both participants. He also studies how children learn and use words, and how they flexibly shift their attention, representations, and inferences.Important LinksCurriculum Vitae: http://goo.gl/qLtUaCLab Website: http://goo.gl/AQ78h6ResearchGate: http://goo.gl/Mj8deHRelevant PapersWatch the hands: infants can learn to follow gaze by seeing adults manipulate objects: http://goo.gl/bSMzKyYoung children’s fast mapping and generalization of words, facts, and pictograms :http://goo.gl/nhykZFA Unified Account of Gaze Following: http://goo.Developmental Science HOA: Episode 12014-08-05 18:00:0098G+

Andrij “Andrew” Harasewych221,280It's been a pretty disappointing year for some of us, celestial sights wise. There have been the usual meteor showers (it was cloudy for me every time), the transit of Venus (also cloudy) and several eclipses (none were visible from my area).Luckily, we still have the Geminids left. They're generally considered to be one of the best and most reliable meteor showers of the year, so hopefully we'll get a good show.They will appear to radiate from the constellation of Gemini, and you could spot up to 120 meteors per hour. The moon will be new meaning that visibility should be very good.Although Dec 13th-14th is the peak, meteors will be visible for several days before and after that so don't forget to look up this week.As usual, if you get any good photographs/videos please send them our way!Geminid Meteor Shower2012-12-14 00:00:00167G+
Andrij “Andrew” Harasewych221,280http://www.redbullstratos.com/The countdown has begun for Felix Baumgartner's epic jump from the edge of space. Supported by a team of experts, Felix will ascend in a helium balloon to an altitude of 120,000 ft / 36,576 m where he will take a leap of faith into the unknown in an attempt to become the first person to break the speed of sound during freefall.To follow the progress of this mission - launch date set for the week of 8th October 2012 - and to find out where and when to tune in to watch Red Bull Stratos rewrite history live please RSVP and join the Event. #science   #redbull   #stratos   #sciencesunday   #spacesunday   #skydiving  +ScienceSunday +Part-Time Scientists +Peter's Scifi page +Red BullRed Bull Stratos Mission - LIVE2012-10-14 14:00:00673G+
Trever McGhee66,747Please accept my apologies if your one of the few that got hit by a bug in their system!This is my first event and for some reason Google notified some people 20 times and for some their system was planning on doing that within their calendars for the next 5 years...every single day...20 times a day...how it did or why it would set peoples calendars up to be notified 20 times a day...I don't know.Hopefully they've got it corrected, if not please let me know.I know I wanted to help peoples wishes come true but not in that way,The goal of this event my Birthday is give you as many of my Birthday Wishes as you require...why because you deserve it.My wish is here is to connect you to the thoughts/ the energy of thousands of people around the world all making a Birthday Wish for themselves from the heart... to you.I like to Imagine the energy from all those making a wish and the energy coming from the ones that come true(the smiles..the laughter..the tears...the overflowing of pure joy) being connected to you to power your own wish to come true.Thanks to some theories about Quantum Physics there's no space between you or me or them...topped with the fact they tell us energy is never destroyed, it's gotta go somewhere as each new person joins in, so why not to you to empower your wish to come true sooner rather than later.Imagine being connected to thousands....millions of others all making wishes...all hoping that your wish comes true for it will help empower their wish.They've documented several cases of where positive thoughts have made a difference, so why not around someones birthday who can then share it with everyone whose connected to that person...so me for this event.It's never been done before, so why not now....be part of it. You have nothing to lose and everything to gain as we go day by day, year by year building this community of wish granters.Now think of an image that represents your wish and then take2seconds to think of that image at least once a day until it comes true.Have fun with it, there's no right or wrong way when you come from the heart.Please let us know as each wish comes true...yes each wish...there's no law that says you're only granted one wish...you deserve everyone of them when they come from the heart..when that wish fills you with the passion for life...*****UPDATE at first I was focused on getting as many people as possible for this so that everyone had more energy but now after reading your comments..hearing your passion for life...the numbers have gone completely out the window for each one of you have brought your own unique energy to the equation that's priceless....THANK YOUIn my world Birthday wishes can be made everyday of the year because it's a celebration everyday that your here to share this with.So today I Celebrate being 44 aUpdate to fix Google Bug for "It's My Birthday and my wish is for your wishes to come true!!"2012-08-17 12:00:00205G+

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

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

Superparamagnets: Superparamagnets have fluctuating... more »

What do you think? Does it makes sense to make a movie from a game itself? Has it been done? I'm actually asking.

This is kind of awesome : The game has some really cool graphics. Like movie cool. I wonder when they will start making movies from games? Not too long to go, I should think.

From PopSci: The revelation of the hit PC game Star Citizen isn’t that people love space-flight—we knew that. It’s that they like their games as realistic as possible, with a universe obsessively hewing to Newton-ian physics for even the smallest detail. The crowdfunded Star Citizen features player-controlled spaceships that travel through a virtual universe governed by the same forces as our own. For example, designers modeled each ship’s landing gear to retract without interfering with the hydrogen fuel system that feeds the nuclear reactor. Then they have to animate heat shielding to close over the landing gear so that the ship can safely pass through an atmosphere.

Star Citizen: 498,500 players have spent more than $48.1 million on virtual ships available for purchase.

+Jacob Dix does some amazing imagery. Thought I would share it here! 

Some space opera images are burned / created in my head from reading stories which fire the imagination. What images are in your head?

Day 18

Enemies and Allies

The shuttle docked in the Crolisa, and previous to leaving I surveyed the space ways. The Jonava had indeed left their homeworld to invade Karmath Mons. They were two days away. The Nacrolis were assembling their armies though I feared they too were too late to defend that young world. I was too deep into quarantined space to reach the battle in time.

Though I remained reluctant to listen to him, my passenger suggested I survey the Djath system. It's an empty system, I told him. But what did I see but the fleets of ice and fire assembling there as well! They were legend. Myth. Ships of metal and manipulated water, rising out of the single sea of Djath, that watery world. They were an old race of giant leviathans, some say cousins of the V-lor, born during the age of the first galactic seeding, long before the younger worlds had reached the planning stages of the heavenly courts.

SciFi August begins!

The story above is the continuation of the previous year's sci fi August. You can read it using the hashtag #SciFiAugust. I will try in the coming days to get links to each portion of the story.

For this month of August I will be exploring outer space, inner space, hyper space and other SciFi spaces and places on my appropriately named Galaxy S3. I would very much like it if you joined in on the fun. Tag any of your creative work that you created during August with the tag:

#SciFiAugust.

These can be in the forms of imagery, painting, story, poetry, sculpture, you name it. Just keep it constrained to science fiction and to August. I wouldn't mind if you also mentioned me in the post but that isn't necessary. It would be nice to see all the fabulous work I anticipate will be created and shared.

Why plagarise when its so easy to credit people, ask them for permission and reshare their work.

Theft

So sci fi August is over for me. While browsing the hashtag for others' works, I came across a community moderator who, instead of resharing two of my images, took poor quality screen shots of my work, cropped them so my old JMD signature I used to use on my images was really visible, and then posted to her community.

My text is there, my name is there, but the image is her screen shot rather than my work. She hasn't responded.

Lame.

This image, btw, it's #SOOC, from my S5.

Have a good day/evening/morning!

If you thought clean energy will automatically be adopted by countries, think again : Its as much a story of politics, of power and of vested interests (for the short term), rather than investing in the long term future of the species.

Who is interested : Well we know the U.S. has walked away from the Kyoto negotiations. And many other developed countries have actually increased carbon emissions instead of decreasing them. Europe and some asian countries and Russia have significantly reduced emissions. Emissions grew more quickly between 2000 and 2010 than in each of the three previous decades.

Analysts say renewable energy now cheaper option than new fossil fuels in Australia : “The perception that fossil fuels are cheap and renewables are expensive is now out of date,” said Michael Liebreich, chief executive of BNEF. “The fact that wind power is now cheaper than coal and gas in a country with some of the world’s best fossil fuel resources (Australia is the world's second largest coal exporter after Indonesia) shows that clean energy is a game changer which promises to turn the economics of power systems on its head." http://www.gizmag.com/renewable-energy-cheaper-australia/26193/

I remember this list.... and yes, I loved Dragon's Egg and Star Trek and a number of the mentioned movies. I remember thinking SF is a great way to introduce kids to science.

Real scientists share their favourite sci-fi books and movies

Both choices are interested, though I suppose I'm looking more at the books here.
Two interesting reminders here are the picks for Permutation City by Greg Egan and Sean Carroll's pick of Dragon's Egg by Robert Forward.

And a reminder of how much I love David Lynch's Dune.

I might fast forward Permutation City, except for the fact that I'm fast forwarding a few other novels at the moment, not least of which is the final book in Hannu Rajaniemi's trilogy, after a reread of The Fractal Prince.___I remember this list.... and yes, I loved Dragon's Egg and Star Trek and a number of the mentioned movies.

I have mixed feelings about this... but the Foundation series was one of my favorite series of books. They kept me enthralled. I still have a picture in my mind of Trantor and the clue of 'At Star's End' was so .... delicious! Anyway, here is a trailer for the movie which never got made, though the choice of director was not the best!

What do you feel?

The Flowing Earth : The Earth's mantle feels solid. But over millennia, we now understand that the mantle drops back towards the Earth's core and gets 'refreshed'.... this is the internal convection current in which the very ground you walk on acts like a fluid (Very much like how a pan of water acts when heated). This also can be modeled to explain the major Earthquakes and volcanoes.

How it works : The Earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat.

How it works : The Earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. At the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.

Viscous fluid : When the forces of buoyancy are applied over millions of years, this seemingly solid material does move and behaves like an extremely viscous fluid and "creeps" along slowly. Most of the worlds earthquakes and volcanoes occur at the boundaries between tectonic plates

How do we know this is how it works : "Obviously, we cannot go inside of the Earth to see what is happening there. However, the process of mantle convection should comply with fundamental physics laws, such as conservation of mass, momentum and energy. What we have done is to simulate the process of mantle convection by solving the equations which controls the process of mantle convection," says Li.

The concept is a little different from a Dyson sphere, but I remember a book called Manifold:Space by Baxter, and much before that a mention of the Dyson tree in a non-fiction book by Carl Sagan.

Do you think this is a good idea to write a story about? People traveling on Dyson trees from planet to planet. It's an evocative idea...

The Dyson Tree

If you’re a fan of science-fiction (or Star Trek), you might have heard the term ‘Dyson Sphere’ before. Therorized by 20th century physicist Freeman Dyson in the 1950s, a Dyson Sphere is a colossal spherical structure constructed around a star, completely surrounding it. The interior of the sphere would absorb the entire energy output of that star, allowing lifeforms to live on the interior surface almost indefinitely.

A Dyson tree is a hypothetical genetically-engineered plant, (perhaps resembling a tree) capable of growing in a comet, suggested by the physicist Freeman Dyson. Plants could produce a breathable atmosphere within hollow spaces in the comet (or even within the plants themselves), utilising solar energy for photosynthesis and cometary materials for nutrients, thus providing self-sustaining habitats for humanity in the outer solar system analogous to a greenhouse in space or a shell grown by a mollusc.

A Dyson tree might consist of a few main trunk structures growing out from a comet nucleus, branching into limbs and foliage that intertwine, forming a spherical structure possibly dozens of kilometers across.

Fire in Zero G : Pulses like a jellyfish, apparently!

From the +Smithsonian Magazine article: Prometheus would be so proud. As part of a NASA experiment, humans have brought fire to the International Space Station (ISS) to see what happens to flames in vanishingly low gravity. The experiment, called Flame Extinguishment-2 (FLEX-2), aims to improve our knowledge of how various liquid fuels burn and what they produce so that we can create cleaner, more efficient combustion engines.

Sometimes one forgets we are on a really well-constructed spaceship : The Shkadov thruster was featured on STNG in an episode called Relic.... h/t to +Kamal Tailor for picking that up. If we were able to move our solar system, where would you want to go?

The Shkadov Thruster : Moving the solar system : The Shkadov thruster is a theoretical mirror larger than the Sun. The role? To potentially move the Sun to another place if required. It has been portrayed in some Science Fiction novels including Bowl of Heaven and its sequel Shipstar by Gregory Benford and Larry Niven. Some of the cosmic megastructures are just amazing in the sheer audacity in the thinking behind them!

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

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

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

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

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

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

If nothing else, our thirst for materials will ensure we go space hopping : At least in the area of Lagrangian space as well as into the vicinity of some asteroids. Space mining may not be a reality yet, but we are getting close.

+Planetary Resources as well as +Deep Space Industries are in a race. And even if the miners may get to robots over time, we already have want ads which look really futuristic "Deep Space Miner wanted." I remember Peter F. Hamilton talking about mining the Hydrogen around Saturn's rings in Reality Dysfunction. What do you think?

Deep Space Industries

Another new asteroid mining venture plans to send fleets of small spacecraft to rendezvous with space rocks, aiming to harvest their contents. That makes two startups now in the asteroid-rush of the early 21st-century teens. This one also plans to use asteroid materials right where they’re found, as feedstock for spaceborne 3-D printers.

Planetary Resources, Inc. made a similar announcement in April 2012, at which time that company said it intended to launch a demonstration mission to Earth orbit within two years.

Likewise, Deep Space says the first Firefly craft will be launched in 2015 on journeys of “two to six months.”

Using low cost technologies, and combining the legacy of our space program with the innovation of today’s young high tech geniuses, we will do things that would have been impossible just a few years ago.

Aliens : Aliens play a large role in science fiction. While some aliens seem to be almost humanoid (especially in TV, since there are issues with creating a species which are not humanoid), a number of authors have experimented with egg-shaped aliens (Peter F. Hamilton), aliens which are invisible (Isaac Asimov), and aliens which are humans from a scattering (Robert L. Forward and Frank Herbert).

What are your favorite stories about aliens? A human-alien partnership like depicted in Earth:The Final Conflict is something which I found most interesting :)

"Windcatchers" - Science fiction images : I like the way this is imagined. Not very out there, and at the same time it has the feeling of a creature one would expect. Though the inspiration is from insects, clearly. Illustrator David Aguilar melds art and science to imagine how alien creatures might adapt to their environments. I find David Aguilar's art a work in progress, though one would have to say it seems like just a jump away from something truly brilliant.

Article Extract: In his latest book, Alien Worlds, Aguilar presents eight worlds, all modeled after Earth-like planets and moons that actually exist in the Milky Way galaxy. Aguilar projects different temperature, gravity, light and water conditions onto these planets—all educated inferences based on the many stages Earth has gone through in its history. In “Ocean World,” for example, the planet’s surface is predominantly water, much like Earth was 450 million years ago, whereas the desert-like “Dying World,” with temperatures ranging from 85 to 140 degrees Fahrenheit, is a glimpse at what Earth could be like about one and a half billion years from now.

“Imagine, if on Earth, one side was always facing the sun, so it was hot and desert-like, like the Middle East, and the opposite side was always facing away from the sun, so it was always in the dark.This is Yelrihs, or the “Infrared World.” Most of the planet’s life forms inhabit the twilight zone—a temperate band running from the North to South Pole. And yet, strong winds blow in this ring, where warm and cool air from both sides of the planet converge.

The artist imagines giant windcatchers, with 30-foot wingspans, that float in the breeze for weeks at a time, descending only to lay their eggs in bodies of water. “It would be like having the most gorgeous kites flying in your sky."

Google and Sharks - what do they have in common? : A lot apparently.... if one is to go by the story on Popsci.

From the article : Google actually goes so far as to wrap its wires in a Kevlar-like material to prevent damage from sharks, a company spokesperson recently disclosed. Sharks seem to like fiber-optic cables more than old-fashioned coaxial copper wires, although it's unclear why.

Patents - is it time for a revamp? : Scientists and researchers have depended on patents from a long time ago. Science has progressed with the ability to protect an idea.

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

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

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

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

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

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

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

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

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

How to store energy using steel, air and water : One of the big challenges of our times is to have an energy storage system which stores energy in the Megawatt range.

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

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

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

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

Black Holes: I had the distinct feeling of being trolled : But I read this article some time back, about how black holes may not have an event horizon.

While others have reported this earlier, I wanted to digest some of the implications before I posted, so this is not news. Just interesting to know :)

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

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

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

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

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

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

In case you missed the Attacknids when they sneaked up on us!

Attacknids Combat Creatures : Saw this on Popsci first. These little chaps are available for $80 in the U.S. I saw something similar sometime back (See the DIY Hack).... The discs are the basic option. The Laser hack is something which I saw in a related article.

Article Extract: With just six legs, these 10-inch-tall battling robots aren't arachnids. They're Attacknids, a hands-on way for kids to build strategic thinking skills and hand-eye coordination while discovering robotics. Each Attacknid comes with Bolt 'N' Battle weapons, including a dissector disc blaster, 20 discs, and clip-on combat armor. Dueling robots fire discs at each other at a distance of up to 30 feet. Each Attacknid's Battle Brain, located on a science-fiction-worthy 360-degree rotating head, can get hit only three times before the robot deactivates, ending the game. (http://goo.gl/3NfqgK)

Laser Attacknid : In a move that wouldn’t look out of place in an Austin Powers movie, a student from Illinois has fitted a spider-shaped robot with laser beams. The remote-controlled Death Ray Laser Drone Bot is fitted with a beam so powerful it can pop balloons and make paper and card burst into flames. (http://goo.gl/mHDrwT)

Company website: http://www.combatcreatures.com/attacknids

From trustedreviews: Looking like the love child of a Starship Troopers arachnid and Kryten from Red Dwarf, the Attacknid is one of the meanest looking toys we’ve seen in a long time. It’s the type of gadget a grown man will fawn over, the sort of toy a father will buy his child just so he can play with it himself.  (trustedreviews.com/attacknids_Gadget_review )

How carbon nanostructures can make better batteries : Lithium in today's batteries are in the electrolyte, not the anode. The reason for this is the issue with anode expansion when using Lithium as an anode. At the nano level, it expands leading to cracks in the structure, which in turn degrades performance.

Thanks to +Sophie Wrobel and +Dirk Reul for reminding me to do the background check on this one.

Nanospheres to protect the Li anode : To solve these problems the Stanford researchers built a protective layer of interconnected carbon domes on top of their lithium anode. This layer is what the team has called nanospheres.

Thanks to +Sophie Wrobel and +Dirk Reul for reminding me to do the background check on this one.

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

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

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

Snakes on a plane? Not really, but lizards in space! : Found this being reported, and decided to try my hand at manipulating images..!

A Russian satellite with five lizards on board is currently floating in space, beyond the control of the researchers who launched it. The Photon-M4 is a research satellite that launched from the Baikinur Cosmodrome on 19 July with the intention of studying the effects of microgravity on plants, insects and gecko mating activities. Mission control lost the ability to control the satellite after it made its first few orbits around Earth.

How to attract a Jaguar to a camera trap : Apparently all you have to do is use Obsession for Men by Calvin Klein around the camera and wait for the magic. Jaguars are largely solitary animals and  is often described as nocturnal, but is more specifically crepuscular (peak activity around dawn and dusk).

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

Visiting Asteroids With Fleets of Nanoprobes : The proposal, known as the Swarm Flyby Gravimetry, was recently awarded a Phase I grant in the NASA Innovative Advanced Concepts (NIAC) program. The goal of the swarm is to create a cheap, fast way to study asteroids by using dozens of microprobes that would scatter around an object in space.

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

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

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

DARPA funds development of space plane for cheaper, faster satellite launches : The cost of putting up satellites in space is huge - not only from a viewpoint of the money involved, but also the effort and fuel expended. Spaceplaces and air-to-space launches are one way to go. This effort from DARPA has been some time in coming, especially since the X-37B has already completed multiple missions. Maybe we can look at dynamic soaring / laser propulsion next?

The goal of the program is to dramatically shrink the cost of putting 3,000- to 5,000-pound satellites into orbit, down to under $5 million per launch. That’s pocket change compared to current space launches, which can cost from 10 to nearly 100 times that amount.

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

Here be dragons

Dinosaurs and Dragons : This is not a new discovery, but the similarity to mythical dragons is striking. And no, humans and dinosaurs did not walk the Earth at the same time. Though dinosaur fossils may well have been unearthed or found by some of our ancestors. Just found this very interesting, and it had the geek in me giggling ;)

Article extract: "Dragons Unearthed," features a 66-million-year-old,  dinosaur called Dracorex Hogwartsia. There’s no denying that Dracorex’s long muzzle and spiky horns conjure up visions of a magical beast, but the museum needed an expert to confirm that it wasn’t a coincidence that Dracorex looked more like a dragon than a dinosaur. Dracorex is named Dracorex hogwartsia in honor of children’s author J.K. Rowling. “The shape of the dinosaur’s skull, with its long muzzle, bizarre knobs and horns, surprised the scientists,” she said. “But the skull looks strangely familiar to anyone who has studied dragons! Dracorex has a remarkable resemblance to the dragons of ancient China and medieval Europe.”

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

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

Lending to a small business for a leg up? No better idea. 

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

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

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

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

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

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

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

So What Do You Want From Me?

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

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

Thanks in advance to all of you. From the amazing crew that participates in my #gqotd  to the writers and assorted folks who follow my #gsotd  posts to the friends I've made via Hangouts I feel grateful to you all regardless!___Lending to a small business for a leg up? No better idea.

NovoPulp Bonus Content Spotlight: 'Science Fiction and Science' by +Lacerant Plainer

We give away free bonus content to anyone who joins the NovoPulp mailing list (http://eepurl.com/C_-Qf ).

Lacerant recently donated the short essay 'Science Fiction and Science' sometime after we released the first wave of bonus content. Here is an extract:

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

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

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

Once you confirm your email address all the bonus content will be emailed to you. Enjoy! :D

T-Minus One Week for the Second Coming of the Apocalypse

I know some of you may not be able to attend. I imagine I will have plenty of time in between now and then to find either a camera, or someone who wants to help take video of this event.

I may have a camera available to use by then. Stay tuned, folks! (Still awaiting confirmation, I'll keep you all informed.)

And I had this crazy dream where I made it to my show, but missed my performance! That's just silly.

And so far, I have a group of friends from work who will be showing up for heckling support. It's going to be exciting!

Again, I am going to be at Rooster T. Feathers, located at:

157 El Camino Real
Sunnyvale, CA 94087

Oh, my, what have we gotten ourselves into this time (again)?

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

In a live webcast, The Planetary Society CEO Bill Nye announced that its long-awaited LightSail solar sail mission will launch to Earth orbit on a SpaceX Falcon Heavy, currently scheduled for an April 2016 liftoff. LightSail-1 and its parent satellite, Prox-1, will be on the same launch vehicle as the U.S. Air Force’s Space Test Program 2 (STP-2) mission.

After ejecting LightSail, the largely student-built Prox-1 will track and image LightSail, including the sail deployment.

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

If you visit Scotland, don't miss flowers made from code.

Flowers made from code : No seriously, this is just beautiful. Daniel Brown makes these brilliant flowers entirely from code.

Article Extract: Digital artist and interaction designer Daniel Brown continues to tweak and evolve his eye-popping series of computer-generated flowers, this time around commissioned by the Art Fund's RENEW program for exhibition at the D'Arcy Thompson Zoology Museum in Dundee, Scotland. The efflorescing clusters of code are, in effect, non-repeating mathematical models, just 1s and 0s colorfully coaxed into roses, orchids, and imaginary floral blooms.

As you can see from Brown's earlier work in the same "Flowers" series—for example, his "Flowers Construction Kit"—the textures and variably focused 3D are both markedly improving over time, and it will be quite extraordinary to see where he might be in another five years. His seeding of artificial ecosystems, to grow matter-realistic flowers in future landscapes, reveals the algorithmic beauty of plants, indeed.

Not news, but something which may be of interest.

The Luna Ring : I am fascinated by the amazing quality of thought which comes from JAXA. They brought us the Solar Sail and the asteroid-hopping spacecraft. Now this new concept is seriously revolutionary. While other countries are talking about Space-based solar power, JAXA is working overtime to see how it can be brought to reality. While the future of power is almost definitely Space based (in my view) it remains to see how we can harness this. The Science exists, it now remains for us to engineer it. Such a concept will easily be able to fulfill our power needs.

Shimizu Corporation's Luna Ring concept : Japanese construction firm Shimizu Corporation has unveiled a proposal which would see a solar panel array built around the moon’s equator, collecting solar energy to then be sent back to Earth. The project, entitled LUNA RING, could see construction begin as early as 2035. Using robots to lay down concrete made from moon soil around the entirety of the moon’s equator — 400 km wide by 11,000 km long — the power generated through the solar array would then be transferred along power cables to microwave power transmission antennas which would then beam the electricity to receiving stations located around the Pacific Rim.

NASA's SpiderFab : NASA is already working on a way to actually 3D print the majority of a solar array in space. A project called SpiderFab is planned to launch with a compact bundle of raw materials, and to use it to 3D print the scaffold for a solar power array more than half a mile across. Then, only the panels themselves would need to go up — making the launch much, much cheaper. We still have to ship the same mass into space, but since the scaffold can be shipped as a solid brick of printable material, it can go up like a cannon-ball, compact and cheap to throw.

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

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

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

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

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

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

Today I learned..... Mortgage literally has its origin in French, which means 'Death Pledge.'

Etymology: From Anglo-Norman mortgage, Middle French mortgage, from Old French mort gage (“death pledge”), after a translation of judicial Medieval Latin mortuum vadium or mortuum wadium, from mortuum + vadium or wadium, of Germanic (Frankish) origin, from a root *waddi, wadja. Compare gage and also wage.

Nanoprobes as explorers and more : Getting to asteroids is an expensive business, especially the cost per weight in sending anything out of earth's orbit is around $1 million for every kilogram.

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

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

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

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