Game of Thrones on Cello!

Amazing share h/t +Avinash Jaisinghani on the GOT theme song

The theme song of HBO’s “Game of Thrones” is considered just as awesome as the show, so it’s no wonder it has generated so many tributes and covers. However, the one above is perhaps the most jaw-dropping you’re likely to hear today, this week or this month.

Cello rock band Break of Reality has thought it fitting to pay tribute to the amazing opening theme from the show, by Ramin Djawadi, with their own, slightly different version.

“We are big fans of the show and have received many requests for this cover. Happy to have finally recorded it!” the band says in the description of the video posted on YouTube.

    Studying the bond between Cats and their Humans

    Article Extract
    It took 120 hours of observing 40 cat-human pairs for scientists to conclude that the bond between the two can be similar to other human relationships. And, yes, I know that most of you who have cats—or know someone who has a cat—will not find that surprising, so let’s delve into the details. It turns out that this study isn’t as simple as it appears.

    The scientists (whose study appears in the journal Behavioural Processes) sent a team of researchers repeatedly into the homes of cat-human pairs in Vienna, Austria. The team would visit for about 45 minutes around the cat’s feeding time, with one person interacting with the cat and human and the other wielding a video camera. They evaluated the personalities of both the human (with a personality test) and the cat, through both observations (e.g., did the cat accompany the human to the door?) and a series of tests that included the cat’s reaction to being picked up. The video of the cat’s behavior and interactions with the humans in the room was later coded and the researchers analyzed it all with a computer program that looked for patterns in the behaviors of the cats and the humans.

    The scientists found some correlations between human personality and the behaviors of the cats—such as that cats with humans classified as “extroverted” or “conscientious” exhibited more complex patters of behaviors—and concluded that “it seems that an important area of negotiation between the owner and the cat is mutual attention and friendly tactile interactions” and that the patterns in the relationships between the cats and humans resemble other long-term and complex relationships, “such as those between humans.”

    Stephen Hawking predicts end-of-Earth scenario

    Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space. Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering. "We must continue to go into space for humanity," Hawking said. "We won't survive another 1,000 years without escaping our fragile planet."

    For years, Hawking has advised people to begin the search for new planets to inhabit. In 2006, he iterated some of today's sentiment saying the survival of the human race depends on its ability to find new homes elsewhere in the universe. In 2011, he said, "Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space."

    Hawking has achieved success in published academic works of popular science in which he discusses personal theories on the universe, its creation and cosmology in general. His book “A Brief History of Time” was on the British Sunday Times best-sellers list for a record-breaking 237 weeks.

    Grow a tooth? : Stem-Cell Dental Implants Grow New Teeth Right In Your Mouth. The loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?

    Dr. Jeremy Mao, the Edward V. Zegarelli Professor of Dental Medicine at Columbia University Medical Center, has unveiled a growth factor-infused, three-dimensional scaffold with the potential to regenerate an anatomically correct tooth in just nine weeks from implantation. By using a procedure developed in the university's Tissue Engineering and Regenerative Medicine Laboratory, Dr. Mao can direct the body's own stem cells toward the scaffold, which is made of natural materials. Once the stem cells have colonized the scaffold, a tooth can grow in the socket and then merge with the surrounding tissue.

    First Tests For Fusion-Powered Spaceship Propulsion Successful

    University of Washington researchers and scientists at a Redmond-based space-propulsion company are currently building components of a fusion-powered rocket, which could enable astronauts to travel to Earth’s neighboring planet Mars within weeks instead of months, at speeds considerably faster than feasible until now. The current travel speeds using fuel rockets make Mars travel a journey of about four years but the new fusion technology being tested by researchers at the University of Washington promises that in 30 to 90 days.

    “Using existing rocket fuels, it’s nearly impossible for humans to explore much beyond Earth,” said lead researcher John Slough, a UW research associate professor of aeronautics and astronautics. “We are hoping to give us a much more powerful source of energy in space that could eventually lead to making interplanetary travel commonplace.”

    The team has developed a technology using a special type of plasma that will be encased in a magnetic field. When the plasma is compressed with high pressure by the magnetic field, nuclear fusion takes place. The process has successfully been tested by researchers and they plan on having the first full test to be done by the end of this summer.

    Article Link: http://www.scienceworldreport.com/articles/6067/20130405/first-tests-fusion-powered-spaceship-propulsion-successful.htm

    Nuclear fusion, in which the nuclei of atoms are forced to join together, could produce vast amounts of energy. Most designs for fusion reactors drive the reaction by confining the fuel in a magnetic field, using a device called a tokamak.

    Unfortunately, tokamaks are prohibitively heavy, so designs for fusion rockets tend to focus on another method of triggering fusion, called inertial confinement fusion.

    Plasma Device Could Revolutionize Energy Generation and Storage

    Scientists at the University of Missouri have devised a new way to create and control plasma that could transform American energy generation and storage. Randy Curry, professor of electrical and computer engineering at the University of Missouri’s College of Engineering, and his team developed a device that launches a ring of plasma at distances of up to two feet. Although the plasma reaches a temperature hotter than the surface of the sun, it doesn’t emit radiation.

    "Launching plasma in open air is the 'Holy Grail' in the field of physics," said Curry, professor of electrical and computer engineering in the University of Missouri's College of Engineering. "Creating plasma in a vacuum tube surrounded by powerful electromagnets is no big deal; dozens of labs can do that. Our innovation allows the plasma to hold itself together while it travels through regular air without any need for containment." The plasma device at MU could be enlarged to handle much larger amounts of energy, according to Curry. With sufficient funding, they could develop a system within three to five years that would also be considerably smaller. He noted that they used old technologies to build the current prototype of the plasma-generating machine. Using newer, miniaturized parts, he suggests they could shrink the device to the size of a bread box.

    “We have a world-class team at MU’s Center for Physical & Power Electronics, but that team will evaporate without funding.”

    Coffee Chemistry

    These latest findings suggest that the antioxidants present in coffee can also lower the risk of heart disease and cirrhosis of the liver.

    Coffee contains hundreds of components including substantial amounts of chlorogenic acid, caffeine, magnesium, potassium, vitamin B3, trigonelline and lignans.

    Chlorogenic acid has been shown in animal experiments to reduce glucose concentrations; coffee also contains tannin, which is beneficial for heart and arteries.

    Researcher Dr. Rob van Dam of the Harvard School of Public Health, says that coffee, if taken in moderate amounts, can actually prevent colon, liver and rectal cancer.

    Coffee isn’t just warm and energizing, it may also be extremely good for you.

    Coffee Can Make You Smarter:
    The active ingredient in coffee is caffeine, which is a stimulant and the most commonly consumed psychoactive substance in the world.
    By blocking the inhibitory effects of Adenosine, caffeine actually increases neuronal firing in the brain and the release of other neurotransmitters like dopamine and norepinephrine. Many controlled trials have examined the effects of caffeine on the brain, demonstrating that caffeine can improve mood, reaction time, memory, vigilance and general cognitive function.

    Coffee Can Help You Burn Fat and Improves Physical Performance
    There’s a good reason why you will find caffeine in most commercial fat burning supplements. Caffeine, partly due to its stimulant effect on the central nervous system, both raises metabolism and increases the oxidation of fatty acids.

    Coffee May Drastically Lower Your Risk of Type II Diabetes
    In observational studies, coffee has been repeatedly associated with a lower risk of diabetes. The reduction in risk ranges from 23% all the way up to 67%. A massive review article looked at 18 studies with a total of 457.922 participants. Each additional cup of coffee per day lowered the risk of diabetes by 7%. The more coffee people drank, the lower their risk.

    Even though coffee in moderate amounts is good for you, drinking way too much of it can still be harmful. The author would also like to point out that many of the studies above were epidemiological in nature. Such studies can only show association, they can not prove that coffee caused the effects.

    Learned behavior of plants : I read about this some time back, but am posting only after I did some digging. There is definitely some gaps in our knowledge of plants and how they get around to taking advantage of their environment. This is a surprising study and you can draw your own inferences from it...

    Article Extract: The researchers studied Mimosa pudica, which folds inwards when touched to protect itself from predators. The University of Western Australia study, which also involved Professor Stefano Mancuso at the University of Florence in Italy, found the action is not simply a reflex.

    They examined the species’ short and long-term memories under both high and low light environments by repeatedly dropping water on the plants using a custom-designed apparatus to look at their response. The strange fauna flora (sic) stopped curling up once it learned that the water was not a threat to its survival and no damage was done, according to the study, which was published in the journal Oecologia. Mimosa plants were able to acquire the learnt behaviour in a matter of seconds and as in animals, learning was faster in low light.
     
    ‘Most remarkably, these plants were able to remember what had been learned for several weeks, even after environmental conditions had changed,' the researchers said. The study shows that Mimosa pudica plants can learn and remember just as well as it would be expected of animals, but of course, they do it all without a brain.

    Carl Warner's Human Bodies make up a landscape : Each landscape in the new series appears to include several bodies, and yet actually is created from photographs of a single person. “The scenes can simply be one shot of a part of their body or multiple shots that are composited together to make a more intricate scene,” Warner explains. “Once I have posed, lit and photographed the subject, I then take the image in to post production in order to grade and finesse it. I simply add a sky to the scene to give the image a sense of scale.”

    The texture of his models’ skin and the shapes that they can make—a bent knee or elbow, an arched back and a flexed abdomen, for instance—give Warner the elements he needs to piece together a barren desert or rocky Moab-like setting. He sketches out a composition before each photo shoot, but inevitably, during the shoot, he sees other poses, which he incorporates into a new drawing.

    Brilliant Earth Time-lapse

    Using footage from the International Space Station, photographer Bruce W. Berry, Jr. created a stunning compilation of our planet

    Heaven meets the Earth in this moving time-lapse video showing gorgeous landscapes underneath an ever-changing night sky.

    A time lapse journey round the Earth, first during the day and then through the night - day time passes over Europe, Africa, the Middle East, and California / Mexico, and night time passes over the UK, Ireland, mainland Europe, the USA, Canada and the Atlantic Ocean. Several night sequences feature the fabulous Northern Lights (Aurora Borealis) and watch out for the Milky Way, and thunderstorms at night over mid-West USA.

    Photograph sequences were taken by the crews of Expedition 30 and Expedition 31 on board the International Space Station (ISS) between December 2011 and June 2012. Images courtesy of the Image Science & Analysis Laboratory, NASA Johnson Space Center,  http://eol.jsc.nasa.gov/

    How fast is Spaceship Earth traveling through space? : The answer is not as simple as one would assume. Because all motion is relative. So it could be a variety of different answers. Depending on the frame of reference, the answer could be zero or a variety of different answers. We do know that everything is moving. The Earth, the Sun, the Milky way, the local galactic cluster..... all of it. Read on to look at the motion from different perspectives....

    Article Extract: The problem with motion is that “true motion” doesn’t exist.  The best we can do is talk about “relative motion” and that requires something else to reference against.  What you consider to be stationary (what you chose to define your movement with respect to) is a matter of personal choice.  The universe isn’t bothered one way or the other.

    Relative to the Earth: The Earth turns on its axis (you may have heard), and that amounts to about 1,000 mph at the equator.  The farther you are from the equator the slower you’re moving.  This motion can’t be “ignored using relativity”, since relativity only applies to constant motion in a straight line, and movement in a circle is exactly not that.On a planetary scale it’s responsible for shaping global air currents.

    Relative to the Sun: The Earth orbits the Sun at slightly different speeds during the year; fastest around new years and slowest in early July (because it’s farther from or closer to the Sun respectively).  But on average it’s around 66,500 mph.  By the way, the fact that this lines up with our calendar year (which could be argued to be based on the tilt of the Earth, which dictates the length of the day) to within days is a genuine, complete coincidence.  This changes slowly over time, and in several thousand years from now it will no longer be the case.

    Relative to the Milky Way: The Sun moves through the galaxy at somewhere around 52,000 mph.  This is surprisingly tricky to determine.  There’s a lot of noise in the the speed of neighboring stars (It’s not unusual to see stars with a relative speed of 200,000 mph) and those are the stars we can see the clearest.  Ideally we would measure our speed relative to the average speed of the stars in the galactic core (like we measure the speed at the equator with respect to the center of the Earth), however that movement is “sideways” and in astronomy it’s much much easier to measure “toward/away” speed using the Doppler effect.  Of the relative speeds mentioned in this post, the speed of our solar system around the galaxy is the only one that isn’t known very accurately.

    Relative to the CMB: The Milky Way itself, along with the rest of our local group of galaxies, is whipping along at 550 km/s (1.2 million mph) with respect to the Cosmic Microwave Background.

    Relative to the Milky Way: The Sun moves through the galaxy at somewhere around 52,000 mph.  This is surprisingly tricky to determine.  There’s a lot of noise in the the speed of neighboring stars (It’s not unusual to see stars with a relative speed of 200,000 mph) and those are the stars we can see the clearest.  Ideally we would measure our speed relative to the average speed of the stars in the galactic core (like we measure the speed at the equator with respect to the center of the Earth), however that movement is “sideways” and in astronomy it’s much much easier to measure “toward/away” speed using the Doppler effect.  Of the relative speeds mentioned in this post, the speed of our solar system around the galaxy is the only one that isn’t known very accurately.

    Relative to the CMB: The Milky Way itself, along with the rest of our local group of galaxies, is whipping along at 550 km/s (1.2 million mph) with respect to the Cosmic Microwave Background.

    A lot of people have asked 'How do I insert special characters?' and there are shortcuts and combinations of keys to be pressed which a number of people have posted about.

    But I remembered this site which has all the characters one could possibly need, and decided to post it here. (please note I am in no way associated with this site!)

    Wireless electricity : Wireless electricity is pretty safe. In 1899,  Nikola Tesla built a 142-foot-tall, 12-million-volt electric coil in Colorado Springs and transmitted electricity wirelessly across 25 miles, illuminating 200 lamps with the charge. After he flipped the switch, flashes of lightning leaped from the coil, but no one was harmed.

    In 2006, Marin Soljacic, a physics professor at the Massachusetts Institute of Technology, sent wireless electricity across a room to light a 60-watt bulb. Soljacic used electromagnetic induction, but with a twist. By tuning the sending and receiving coils in his electromagnetic field to resonate at the same frequency and engage only at that frequency (the way glass will shatter when struck by sound waves of just the right pitch), the current is focused and bypasses everything else, humans included. Resonant coupling, as Soljacic's process is known, is far more efficient than Tesla's attempts, and safer too.

    Thorne-Zytkow objects : Still not 'news' but astronomers have a candidate for a Thorne-Zytkow object. What is it? When a superdense neutron star is captured by a red giant or supergiant star. One star is then nested in the other. This was first theorized in 1975, but no such star had been found...yet..... read on!

    Article Extract: Once the neutron star is eaten, it settles in the core of the supergiant, interrupting normal fusion processes inside the star’s guts. This, according to the theorists, should create a very specific chemical signature in the “host” star’s chemical make up. What’s more, there should be a few dozen Thorne-Żytkow object specimens in our galaxy.

    Emily Levesque, of the University of Colorado in Boulder, has reported the discovery of another Thorne-Żytkow object candidate, the strongest candidate to date. Levesque announced her discovery at the 223rd American Astronomical Society meeting in Washington, D.C., but fell short of naming the particular star as her research has yet to be published in a peer-reviewed journal.

    What is known, however, is that the star is one of 22 supergiants surveyed in the Small Magellanic Cloud, a dwarf galaxy next door to the Milky Way, by the Magellan telescopes in Chile. The mystery oddball stellar behemoth has elevated quantities of lithium, rubidium and molybdenum — elements that are theorized to arise from the presence of a neutron star inside a red supergiant, forcing the old star to carry out different forms of fusion processes.

    3D Printed Moon base

    The European Space Agency (ESA) is looking to build a lunar base with 3D printing using local materials on the moon. The 3D structures are built layer-by-layer. The lunar material would be combined with magnesium oxide, which turns it into a "paper" to be printed with. Then, for the "ink," a binding salt is added to transform the material into a solid. The architects are trying to create a structure that can handle the harsh weather and environment that the moon can have. “3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth,” said Scott Hovland of ESA’s human spaceflight team.

    Dini's Plans for a Moonbase
    Dini has lunar plans for the D-shape, and is in discussions with La Scuola Normale Superiore, Norman Foster (a UK architecture firm), and Alta Space, as part of the Aurora program run by the European Space Agency (ESA), to build a modified D-Shape that could use lunar regolith (moon dust) to build a moon base. Dini will carry out trials in a vacuum chamber at Alta Space’s facility in Pisa to ensure the process is possible in a low-atmosphere environment such as the moon.

    Giant NASA spider robots could 3D print lunar base
    Sintering is quite cheap, in terms of power as well as materials, and an Athlete rover should be able to construct a bubble volume in only two weeks, Rousek estimates. He said: "It would have a very good cost-value ratio as you don't need to import as much material from Earth. The whole expandable module, with the membranes to cover the base when built, would be carried by the same rocket that would bring other modules of the outpost, but it can build a volume four times bigger than a rigid cylindrical module. Since we don't have the necessary transport capacity to the Moon at the moment, estimating a price now would be very inaccurate.

    When will wireless power reach the tipping point?

    If you’re waiting to see when wireless power will hit the mass market, then you’re not alone. Delivering power wirelessly is perhaps one of the most hyped, long anticipated changes to the way we design and use products and machinery since the invention of electricity itself. But if you’ve been watching this space, you’ll know these solutions have been slow in coming to market and are anything but commonplace.

    Why is that? What’s it going to take for this technology to hit the mainstream? Over the past two years we have witnessed first generation implementations of wireless power, mostly in the smartphone after-market. These come in the form of sleeves and charging pads but are rarely sighted amongst early adopters. Each claims to be supporting the best technology — the one that will lead the world in becoming completely unplugged. Yet, in my view, what we have seen and heard so far are a combination of impossible claims and poor end-user functionality.

    WiTricity CEO Eric Giler imagines a future where power devices are embedded in the walls and carpets of homes, making for a truly wire-free household. He says with a big enough power supply and small wireless repeaters, one could even power a grocery store or office building. Conventional charging devices such as the cord for a cell phone use electromagnetic induction to transmit power. Through electromagnetic induction, an electric current is sent through a magnetic field generated by a power conductor to a smaller magnetic field generated by a receiving device. (See related quiz: "What You Don't Know About Electricity")

Through electromagnetic induction, an electric current is sent through a magnetic field generated by a power conductor to a smaller magnetic field generated by a receiving device.

    The Science behind the Eternal Shelf Life of Honey : Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the eternal shelf-life of honey. Honey can remain preserved in a completely edible form, and while you wouldn’t want to chow down on raw rice or straight salt, one could ostensibly dip into a thousand year old jar of honey and enjoy it, without preparation, as if it were a day old. Moreover, honey’s longevity lends it other properties–mainly medicinal–that other resilient foods don’t have.

    “Honey in its natural form is very low moisture. Very few bacteria or microorganisms can survive in an environment like that, they just die. They’re smothered by it, essentially.” What Harris points out represents an important feature of honey’s longevity: for honey to spoil, there needs to be something inside of it that can spoil. With such an inhospitable environment, organisms can’t survive long enough within the honey to have the chance to spoil. Honey is also naturally extremely acidic. “It has a pH that falls between 3 and 4.5, approximately, and that acid will kill off almost anything that wants to grow there,” Harris explains. So bacteria and spoil-ready organisms must look elsewhere for a home–the life expectancy inside of honey is just too low.

    Nectar, the first material collected by bees to make honey, is naturally very high in water–anywhere from 60-80 percent, by Harris’ estimate. But through the process of making honey, the bees play a large part in removing much of this moisture by flapping their wings to literally dry out the nectar. On top of behavior, the chemical makeup of a bees stomach also plays a large part in honey’s resilience. Bees have an enzyme in their stomachs called glucose oxidase (PDF). When the bees regurgitate the nectar from their mouths into the combs to make honey, this enzyme mixes with the nectar, breaking it down into two by-products: gluconic acid and hydrogen peroxide. “Then,” Harris explains, “hydrogen peroxide is the next thing that goes into work against all these other bad things that could possibly grow.”

    A jar of honey’s seal, it turns out, is the final factor that’s key to honey’s long shelf life, as exemplified by the storied millennia-old Egyptian specimens. While honey is certainly a super-food, it isn’t supernatural–if you leave it out, unsealed in a humid environment, it will spoil. As Harris explains, ” As long as the lid stays on it and no water is added to it, honey will not go bad. As soon as you add water to it, it may go bad. Or if you open the lid, it may get more water in it and it may go bad.”

    Swarm robotics

    Swarm robotics is a technological technique of using multiple simple robots to work as a team and follow instructions. This technology has been greatly inspired by the nature. There are many animals, insects and fishes which live in a swarm.

    If you've ever seen a trail of ants streaming up a wall or over a counter, you'd be forgiven for thinking they were working in strict, militant harmony. Not so. A robotic test bed developed at the New Jersey Institute of Technology in Newark shows that this apparent order can emerge in artificial bodies following just a few simple rules.

    Symbrion (Symbiotic Evolutionary Robot Organisms) is a project funded by European Commissions to develop a framework in which a homogeneous swarm of miniature interdependent robots can co-assemble into a larger robotic organism to gain problem-solving momentum. One of the key-aspects of Symbrion is inspired by the biological world: an artificial genome that allows to store and evolve (sub)optimal configurations in order to achieve an increased speed of adaptation.

    Dr Roderich Gross, head of the Natural Robotics Lab, in the Department of Automatic Control and Systems Engineering at the University of Sheffield, says swarming robots could have important roles to play in the future of micromedicine, as 'nanobots' are developed for non-invasive treatment of humans. On a larger scale, they could play a part in military, or search and rescue operations, acting together in areas where it would be too dangerous or impractical for humans to go. In industry too, robot swarms could be put to use, improving manufacturing processes and workplace safety.

    Bacterial Evolution : How Bacteria evolve and behave may answer many questions about life itself. These ancient organisms evolved since the beginning of biology on Earth, and some of the mysteries of our existence is locked in their code. Researchers are just starting to understand some of the basic goals of such organisms, and the findings are fascinating and quite interesting.

    Evolution Never Stops : Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world. That's the latest surprise from a unique experiment that's been underway for more than a quarter-century. Day after day — including holidays and weekends — workers in Lenski's lab at Michigan State University in East Lansing feed and care for the E. coli bacteria. The bacteria eat and divide again and again. The original microbes have produced more than 50,000 generations over the last 25 years. It turns out, though, that the bacteria haven't stopped evolving, and it looks like they never will, according to a in the journal Science.

    DNA Grabbing Bacteria : Lab tests involving microbes and a mammoth bone have shown that bacteria can passively soak up the genetic remains of long-dead organisms from the environment and add them to their own genomes. By absorbing snippets of DNA that float in the environment, bacteria can access a junk shop of genetic material – some of which may no longer be in circulation in living things. What's more, the mechanism requires hardly any cellular machinery, suggesting it may be left over from the earliest forms of life. Long before the advent of sex, the first cells may have randomly scavenged stray bits of DNA to survive and evolve.

    Bacteria join forces to create electricity : Bacterial cells use an impressive range of strategies to grow, develop and sustain themselves. Despite their tiny size, these specialized machines interact with one another in intricate ways. The research group demonstrates that the light-sensitive green sulfur bacterium Chlorobium can act in tandem with Geobacter, an anode respiring bacterium. The result is a light-responsive form of electricity generation.

    Theia : One of the most favored theories which explains the formation of the Moon involves a collision with a large Mars-sized planet called Theia. The impactor not only increased the size of Earth, it also gave us a large Moon, vital to life on our planet.

    Article extract: The giant impact hypothesis states that the Moon was formed out of the debris left over from a collision between the Earth and a body the size of Mars, approximately four and a half billion years ago. Supporting evidence includes: the Earth's spin and Moon's orbit having similar orientations, Moon samples indicating the surface of the Moon was once molten, the Moon's relatively small iron core, lower density compared to the Earth, evidence of similar collisions in other star systems (that result in debris disks), and that giant collisions are consistent with the leading theories of the formation of the solar system. Finally, the stable isotope ratios of lunar and terrestrial rock are identical, implying a common origin.

    From Space.com : New research potentially plugs a big hole in the giant impact theory, long the leading explanation for the moon's formation. Previous versions of the theory held that the moon formed primarily from pieces of a mysterious Mars-size body that slammed into a proto-Earth — but that presented a problem, because scientists know that the moon and Earth are made of the same stuff. The two studies both explain how Earth and the moon came to be geochemical twins. However, they offer differing versions of the enormous smashup that apparently created Earth's natural satellite, giving scientists plenty to chew on going forward.

    Concept Car which uses photosynthesis!

    SAIC YeZ Concept Car inhales C02, emits Oxygen

    Love this concept; how often do you hear Car and Photosynthesis in the same sentence?

    The concept vehicle features solar panels, which are located on the rooftop and small wind turbines, placed on its wheels. Besides the solar panels, the roof of the YeZ will benefit from an innovative system that will capture carbon dioxide from the surrounding air and then release oxygen in the atmosphere.

    The electric energy generated by the solar panels and the wind turbines it’s going to be stored in onboard batteries that will power the vehicle. No technical specifications are available, since the YeZ concept is only a dream of eco-friendly cars that will be used in 2030.

    Not much info has been made available in the YeZ, but SAIC claims it will “work during both sunny and overcast days while also being able to leverage wind power”, enabling “mobility with zero greenhouse gas emissions.”

    Unless solar panel efficiency evolves massively in the next two decades, we expect the YeZ will have a regular appointment at the powerpoint, but, that isn't all that bad.

    How The CIA Tried To Turn A Cat Into A Cyborg Spy

    Misadventure though it was, the agency's Operation Acoustic Kitty was a visionary idea 50 years ahead of its time.

    n the 1960s, the Central Intelligence Agency recruited an unusual field agent: a cat. In an hour-long procedure, a veterinary surgeon transformed the furry feline into an elite spy, implanting a microphone in her ear canal and a small radio transmitter at the base of her skull, and weaving a thin wire antenna into her long gray-and-white fur. This was Operation Acoustic Kitty, a top-secret plan to turn a cat into a living, walking surveillance machine. The leaders of the project hoped that by training the feline to go sit near foreign officials, they could eavesdrop on private conversations.

    The problem was that cats are not especially trainable—they don’t have the same deep-seated desire to please a human master that dogs do—and the agency’s robo-cat didn’t seem terribly interested in national security.

    Operation Acoustic Kitty, misadventure though it was, was a visionary idea just 50 years before its time. Today, once again, the U .S. government is looking to animal-machine hybrids to safeguard the country and its citizens. In 2006, for example, DARPA zeroed in on insects, asking the nation’s scientists to submit “innovative proposals to develop technology to create insect-cyborgs.”

    Consider two of the tiny, completely synthetic drones that engineers have managed to create: The Nano Hummingbird, a flying robot modeled after the bird, with a 6.5-inch wingspan, maxes out at an 11-minute flight, while the DelFly Micro, which measures less than 4 inches from wingtip to wingtip, can stay airborne for just 3 minutes.

    Why are humans the only living creatures that cook their food : It was a simple question. Which led me down some narrow paths. Fascinatingly, it has to do with digestion, calories, our brains and chemistry! The energy equation with cooked food changes substantially to allow us to have a much larger brain. So now I know!

    Article Extract: Without cooking, an average person would have to eat around five kilos of raw food to get enough calories to survive. The daily mountain of fruit and vegetables would mean a six-hour chewing marathon.

    Harvard Professor Richard Wrangham believes that it is not so much a change in the ingredients of our diet, but the way in which we prepare them that has caused the radical evolution of our species. Homo erectus had an even bigger brain, smaller jaws and teeth. Homo Erectus also had a similar body shape to us. Shorter arms and longer legs appeared, and gone was the large vegetable-processing gut, meaning that Erectus could not only walk upright, but could also run. He was cleverer and faster, and - according to Professor Wrangham - he had learned how to cook. "Cooking made our guts smaller," he says. "Once we cooked our food, we didn't need big guts. "They're costly in terms of energy. Individuals that were born with small guts were able to save energy, have more babies and survive better." Professor Peter Wheeler from Liverpool John Moores University and his colleague, Leslie Aiello, think it was this change in our digestive system that specifically allowed our brains to get larger.

    As an example, researchers have investigated the effects of cooking on starch molecules and humans' ability to digest cooked versus raw grains. Simply cooking starchy foods increases the net energy gain by 30 percent, he said. "The grains themselves represent long chains of glucose, which are very difficult to digest until they have been gelatinized; you are opening up these chains," he said.

    Take, for example, a simple white sauce of flour and butter. You have to stir constantly over even heat, letting the water in the butter invade the starch molecules in the grain. "Then you get this change in consistency, where the whole thing becomes a continuous colloid, and the starch grains have become gelatinized. The result is that it will be easier to digest," Wrangham said. "Our body pays fewer calories for the digestion."

    Henry Segerman’s Mathematical Sculptures

    To say that Henry Segerman is schooled in mathematics is an understatement. The 33-year-old research fellow at the University of Melbourne, in Australia, earned a master’s degree in math at Oxford and then a doctorate in the subject at Stanford. But the mathematician moonlights as an artist. A mathematical artist. Segerman has found a way to illustrate the complexities of three-dimensional geometry and topology—his areas of expertise—in sculptural form.

    First things first…three-dimensional geometry and topology? “It is about three-dimensional stuff, but not necessarily easy to visualize three-dimensional stuff,” says Segerman, when we talk by phone. “Topology is sort of split along low-dimensional stuff, which usually means two, three and four dimensions, and then high-dimensional stuff, which is anything higher. There are fewer pictures in the high-dimensional stuff.”

    Since 2009, Segerman has made nearly 100 sculptures that capture, as faithfully as is physically possible, some of these hard-to-grasp lower-dimensional mathematical concepts.He uses a 3D modeling software called Rhinoceros, typically used to design buildings, ships, cars and jewelry, to construct shapes, such as Möbius strips, Klein bottles, fractal curves and helices. Then, Segerman uploads his designs to Shapeways.com, one of a few 3D printing services online. “It is really easy,” he says. “You upload the design to their Web site. You hit the ‘add to cart’ button and a few weeks later it arrives.”

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

    How does it all work? : We used to think our relationship with bacteria was simple; there were good ones that kept our digestive tracts healthy and there were bad ones that made us sick. We now know that many bacteria can play both roles, living happily in us or on us as part of a healthy microbiome, but capable of turning nasty under certain conditions. Now there are claims that a truly villainous bacterium – Mycobacterium tuberculosis, which causes TB – is actually symbiotic and helped us evolve our large brains. (NewScientist source : http://goo.gl/ziuLmM and related NCBI research: http://goo.gl/iQ3SAM)

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

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

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

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

    How does it all work? : We used to think our relationship with bacteria was simple; there were good ones that kept our digestive tracts healthy and there were bad ones that made us sick. We now know that many bacteria can play both roles, living happily in us or on us as part of a healthy microbiome, but capable of turning nasty under certain conditions. Now there are claims that a truly villainous bacterium – Mycobacterium tuberculosis, which causes TB – is actually symbiotic and helped us evolve our large brains.

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

The study shows how the people and pets you live with affect the microscopic bacteria, fungi and other creatures living all over your body.

    Synchronicity : We are always living slightly behind reality. While this is just a few milliseconds, it's still something which is quite interesting.

    Article Extract: "Time" is something that both philosophers and physicists have been wondering for about, well, a long time. And now, the neuroscientists have joined in. They have found a man who, when he looks at you, hears what you are saying to him before your lips move.

    About two to three months after the onset of the myaesthenia gravis, Mr PH noticed something strange about his daughter's TV sets. He was hearing people on the TV speak before he saw the lips move and he said to his daughter: "Hey, you've got two TVs that need sorting!" But the TVs were fine. Instead, something odd was happening to the timing circuits inside his brain. Now you might not realise this, but in terms of vision you are always living 0.3 second (or 300 milliseconds) behind reality. That's how long it takes between when the incoming light lands on the cells in your retina, and you get that full magnificent wraparound 3D colour sensation that we call vision.

    We don't notice this delay in reality because we have evolved to be able to deal with this. We can anticipate actions or patterns through experience. Now it turns out that it also takes time for the incoming audio signals from our ears to be processed. If you've ever dealt with audio and video computer files, you would know that the audio files are much much smaller than the video files. So in the case of the human brain, when the Brodmann areas associated with hearing, areas 41 and 42, start processing the incoming audio information, they can do so quite quickly, because the amount of data is rather small. Normally, we process this audio information in just 100 milliseconds.

    So how come we normally see the lips moving at the same time as we hear the voice? Almost certainly, it's because our brain deliberately inserts a delay of about 200 milliseconds on the audio circuit.

    Why does vision take so long to resolve? : There's a lot that has to happen inside your head. First, the rods or the cones in your retina turn the incoming light into electricity. Then the remaining nine layers of cells in the retina compress and process that electricity. By this time, your retina 'knows' the difference between a horizontal bar in your field of view and a vertical bar. Furthermore, your retina 'knows' if it's a white bar on a black background or vice versa. Then the compressed signal gets sent along the optic nerves to some sections of your brain right at the back of your skull called the Brodmann areas 17, 18 and 19. These then decompress and deconvolute the electrical information to give you this thing we call 'vision'. This all takes a significant amount of time — 300 milliseconds.

    Concept Waterscraper

    For the last five years, eVolo Magazine has hosted a futuristic skyscraper design competition. Usually, the entrants imagine giant buildings taller than anything under construction today. However, the most impressive entry in this year's competition goes the opposite route, by dropping the building straight into the sea. This floating building would generate its own electricity and food, house thousands, and plunge deep beneath the waves.

    Designed by Sarly Adre bin Sarkum of Malaysia, the waterscraper would be about as tall as the Empire State Building, but with only a couple of stories exposed above the surface. The whole building would be a self-sufficient, floating, arcology. Wind, solar, and wave power would provide energy, hydroponics and the green space at the top would provide food and oxygen, and the structure would provide housing, work spaces, and areas for recreation.

    Ballast tanks would keep the structure level, like in a submarine, as would the tentacles. The tentacles would also move around in the ocean tides, generating electricity from kinetic energy.

    Adre bin Sarkum deliberately designed this building to contrast with the skyscrapers that dominate the rest of the competition, and to highlight sustainable architecture.

    Obviously, no one has any plans to build anything remotely like this. But if global warming throws us into a WaterWorld like future, Adre bin Sarkum's aqua-condo looks like much sweeter digs than a rickety boat captained by a urine-drinking fish-man.

    Brinicle: Icy death: What's cooler than being cool? Brine-cold. When salt-rich water leaks out of sea ice, it sinks into the sea and can occasionally create an eerie finger of ice called a brinicle. New research explains how these strange fingers of ice form and how the salty water within sea ice could have been a prime environment in which life may have evolved.

    When sea ice freezes, the salt and other ions in the water is excluded from the water crystals, said study author Bruno Escribano, a researcher at the Basque Center for Applied Mathematics in the Basque Country in northern Spain. This salt-heavy brine accumulates in fractures and compartments within the sea ice. (Typically the sea ice forms over water, so a number of creatures live under the sea ice).

    Inevitably, however, sea ice cracks, and the brine leaks out. The brine itself is colder than the freezing point of seawater, since salt-rich water freezes at lower temperatures (hence the reason people put salt on icy sidewalks in the winter, enabling the ice to remain a liquid when it's below freezing).

    Since the concentration of water in the brine is lower than that in the ocean — and water moves from high to low concentrations, via osmosis — water is attracted to the brine. But the brine is so cold that the water freezes, forming a descending tube of ice.

    Pic Detail: A brinicle grows from the ice sheet above in McMurdo Sound, Antarctica. Over the course of 12 hours, it descends to the seafloor below, then extends another 20 feet along the sea bed, trapping anything it touches in ice. Most creatures here move far too slowly to escape its path of death.

    Is the mass of Earth increasing? : An interesting question which someone once asked me on a post which got me thinking. Yes due to a number of factors, and No due to an equal number of factors. Logically speaking, since there are a number of factors, we need to do some math...

    Article Extract: Using some back-of-the-envelope-style calculations, Dr Smith, with help from physicist and Cambridge University colleague Dave Ansell, drew up a balance sheet of what's coming in, and what's going out. All figures are estimated. By far the biggest contributor to the world's mass is the 40,000 tonnes of dust that is falling from space to Earth, says Dr Smith.

    Another much less significant reason the planet is gaining mass is because of global warming. Nasa has calculated that the Earth is gaining energy due to rising temperatures. Dr Smith and his colleague Mr Ansell estimate this added energy increases the mass of Earth by a tiny amount - 160 tonnes.

    Population growth and new buildings are not a factor, because both of these are actually made up of existing matter on the planet.

    The Earth's core is like a giant nuclear reactor that is gradually losing energy over time, and that loss in energy translates into a loss of mass. But there is something else that is making the planet lose mass. Gases such as hydrogen are so light, they are escaping from the atmosphere. "Physicists have shown that the Earth is losing about three kilograms of hydrogen gas every second. It's about 95,000 tonnes of hydrogen that the planet is losing every year.

    Overall, Dr Smith has calculated that the Earth - including the sea and the atmosphere - is losing mass.

    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.

    How to get ignored on Google plus : This is a departure from my usual posts. I've been getting notified. A lot. From all kinds of people who may or may not have a reason to notify others. Here are some things you can do to get noticed (And not ignored as the title suggests) in a good way....

    Talk to people : Read people's posts. Talk to them. Comment. Maybe talk about common interests. In real life do you just walk upto someone and say "Hey I'm a writer.... read my book?" or "Buy teeshirts from me?"... there is an art to engaging and marketing yourself. And spamming someone is the worst way to do it.

    Find people with common interests : Circles are the lifeblood of Google plus. But general circles often get numbers and not common interests. You have to tend to your circles like a gardener. Weed out the ones you don't want. Add in new people. Share circles with targeted interests. I have one here - http://goo.gl/g5czCB

    Don't invite and notify people randomly : I do notify people. They have asked to be notified. These are people who I know by name. They know the kind of stuff I post. They want to see an email from me. I do the same for some. Don't just notify people. It will earn you an Mute / Block from people. Maybe a report and and a ban.

    Treat people the way you want to be treated : Yes, I said it. Each profile here is a person. Like it or not, they have similar requirements of privacy, politeness etc. which you would expect.

    Don't start a flame war on someone else's post : When you are commenting on someone's post be respectful. The original poster is the host. You are a guest and your comments are valuable. Make sure you don't hog the comments section. Very often one-upmanship earns you a block and report from the OP.

    Be a good netizen : Googleplus is my virtual living room. Make it yours as well. Make it a place to put your feet up and relax with friends. I often picture everyone with a drink discussing things over a fireplace.

    3D Printed Prosthetic arm : It does capture the imagination and is a wonderful idea. The Nottingham researchers have revealed some exciting possibilities.

    Article extract: 3D printing can render everyday artefacts in clear plastic, so we can see in unprecedented detail how they work – and this exquisite model of a prosthetic arm is a brilliant example. It is one of the highlights at the London Science Museum's 3D printing exhibition. Designed by Richard Hague, director of the Additive Manufacturing and 3D Printing Research Group at the University of Nottingham, UK, and his students the arm shows how the printers can create strong structure, mobile joints and delicate sensors – like spiral-shaped metal touch-detectors – all in one process.

    "It's a mock-up but it shows circuits that sense temperature, feel objects and control the arm's movement," says Hague. "3D printing gives us the freedom to make complex, optimised shapes, and our research aim is focused on printing-in electrical, optical or even biological functions."

    The woodpecker : Tongues that can be over double their body length, barbed, with a sensing mechanism, and a skull that can withstand 1000 Gees when slamming their beaks against wood . The woodpecker is indeed amazing!.

    In order to navigate the insect gallery, some woodpecker's tongue is so long it forks in the throat, goes below the base of the jaw, and wraps behind and over the top of the head, where the forks rejoin and insert in the bird's right nostril (below left) or around the eye socket. Within the entire length of woodpecker's tongue lies the "hyoid apparatus," a linear series of tiny bones sheathed in muscles and soft tissue; the ultra-thin hyoid bones, which fold up accordion-like along part of their length.The woodpecker's tongue also contains paired longitudinal muscles that move it side to side as the bird probes for food.

    Woodpeckers' head-pounding pecking against trees and telephone poles subjects them to enormous forces — they can easily slam their beaks against wood with a force 1,000 times that of gravity. (In comparison, Air Force tests in the 1950s pegged the maximum survivable g-force for a human at around 46 times that of gravity, though race-car drivers have reportedly survived crashes of over 100 G's.)

(In comparison, Air Force tests in the 1950s pegged the maximum survivable g-force for a human at around 46 times that of gravity, though race-car drivers have reportedly survived crashes of over 100 G's.)

    The woodpecker : Tongues that can be over double their body length, barbed, with a sensing mechanism, and a skull that can withstand 1000 Gees when slamming their beaks against wood . The woodpecker is indeed amazing!.

    In order to navigate the insect gallery, some woodpecker's tongue is so long it forks in the throat, goes below the base of the jaw, and wraps behind and over the top of the head, where the forks rejoin and insert in the bird's right nostril (below left) or around the eye socket. Within the entire length of woodpecker's tongue lies the "hyoid apparatus," a linear series of tiny bones sheathed in muscles and soft tissue; the ultra-thin hyoid bones, which fold up accordion-like along part of their length.The woodpecker's tongue also contains paired longitudinal muscles that move it side to side as the bird probes for food.

    Well we have all debated if we are in the Matrix : But scientists are looking at testing the hypothesis. Some surprising parallels do exist - all matter is information, the pixellation in a computer can be likened to the smallest building blocks of all matter, and dark matter may well be one of the algorithms of such a simulation.

    Article extract: Three physicists at the University of Washington in Seattle are working on new ideas to test Bostrom’s “simulation hypothesis.” In a paper recently posted on arXiv, a scientific e-print service, University of Washington theoretical physicist Martin Savage and colleagues, note that the underlying lattice structure imprint of such quantum super-computer numerical simulations might involve dividing our observed space-time continuum into a “four dimensional grid.”

    Even though science fiction is rife with holographic realities and simulations used to both entertain and control, Bostrom says the fact that we may be living in a simulated universe wouldn’t mean that we’re any “less real” than biological entities in a non-simulated universe.
