NASA finds extra-terrestrial amino-acids in Sudan meteorites Earlier this month, NASA announced the discovery of bacteria living in arsenic in a California lake. Now they have uncovered ET amino-acids in meteorite fragments that landed in northern Sudan. The meteorite was a fragment of a parent asteroid measuring 13-feet-wide (4m), and weighing 59-tons. Scientists were given the first opportunity to observe a celestial object before it entered our atmosphere in October 2008 after a collision about 15 million years ago sent the asteroid closer to Earth. During expeditions in the Sudanese desert, scientists later recovered nearly 600 meteorite fragments from the meteor shower. Just a few weeks ago, the bacteria living in arsenic finding presented by NASA, was preceded by media speculation about the possibility that the space agency would announce that it had found life in outer space.
Scientists capture first image of two atoms INSIDE a molecule (but we'll just have to take their word for it) By Rob Waugh Published: 18:51 GMT, 8 March 2012 | Updated: 12:28 GMT, 9 March 2012 A new photograph shows two atoms vibrating together inside a molecule - a first for science. Researchers used a mind-boggling technique where they turned an electron into a 'flash bulb' to capture the image. Why aren’t coyotes, dingoes and wolves treated like our dogs? Drinking her coffee one sunny winter morning, Pamela Karaz looked out the window of her home in upstate New York and saw a coyote walking up the driveway. It was an uncommon sight – coyotes tend to be secretive – but what happened next was even more surprising. The coyote marked a tree with his scent, strolled across her yard, sniffed at a few tracks and then noticed a bright blue plush toy Karaz had bought a few days earlier for Bristol, her golden retriever. Bristol had left the toy outside, as was her habit. Now the coyote sniffed it, picked it up in his mouth, dropped it, picked it up again.

How fast is our galaxy moving through space "The Milky Way and the Andromeda galaxy are approaching each other with a speed of 300,000 miles per hour." or 130 km/s As we all know, a galaxy is a massive ensemble of hundreds of millions of stars. The galaxy where we live in today is called the Milky Way. The name itself came from the ancient Greek galaxies kyklos, or ring of milk, due to its faint milky appearance. Our Milky Way is a large spiral galaxy.
Quantum Computers Will Solve Problems that would take Today's Computers Longer than the Age of the Universe Astrophysicist Paul Davies at Arizona State University proposes that information, not mathematics, is the foundation on which physical reality, the laws of nature, are is constructed. Meanwhile at MIT, computer scientist Seth Lloyd, develops Davies assumption, by treating quantum events as "quantum bits," or qubits, as the way whereby the universe "registers itself." Lloyd proposes that information is a quantifiable physical value, as much as mass or motion -that any physical system--a river, you, the universe--is a quantum mechanical computer. Lloyd has calculated that "a computer made up of all the energy in the entire known universe (that is, within the visible “horizon” of forty-two billion light-years) can store about 1092 bits of information and can perform 10105 computations/second."
Why Very Smart People Are Happiest Alone In a just-published study about how our ancestral needs impact our modern feelings, researchers uncovered something that will surprise few among the highly intelligent. While most people are happier when they’re surrounded by friends, smart people are happier when they’re not. The researchers, Norman P. Li and Satoshi Kanazawa, of the Singapore Management University, Singapore and the London School of Economics and Political Science, UK, respectively, were investigating the “savannah theory” of happiness. The savannah theory — also called the “evolutionary legacy hypothesis” and the “mismatch hypothesis” — posits that we react to circumstances as our ancestors would, having evolved psychologically based on our ancestors’ needs in the days when humankind lived on the savannah.
A New App That Lets You Take Apart Websites and Rebuild Them At Will You used to have to be a programmer just to use computers at all. Graphical user interfaces changed all that. But what if you want to build software? Increasingly, you don't have to be a coder to do that, either. Speed of the Milky Way in Space As we all know, a galaxy is a massive ensemble of hundreds of millions of stars. The galaxy where we live in today is called the Milky Way. The name itself came from the ancient Greek galaxies kyklos, or ring of milk, due to its faint milky appearance.
Tiny 'Soccer Ball' Space Molecules Could Equal 10,000 Mount Everests For the first time, astronomers have discovered the solid form of tiny carbon spheres in deep space inside a vast cloud of particles locked in orbit around two distant stars. The carbon spheres, known as buckyballs, are formed from 60 carbon atoms linked together to form a hollow sphere, "like a soccer ball," NASA announced in a statement today (Feb. 22). Astronomers spotted vast quantities of the tiny space balls, enough to create 10,000 Mount Everests, circling a pair of stars 6,500 light-years from Earth. "These buckyballs are stacked together to form a solid, like oranges in a crate," said the study's lead author Nye Evans of Keele University in England in a statement.
Remarkable New Theory Says There's No Gravity, No Dark Matter, and Einstein Was Wrong Gravity is something all of us are familiar with from our first childhood experiences. You drop something - it falls. And the way physicists have described gravity has also been pretty consistent - it’s considered one of the four main forces or “interactions” of nature and how it works has been described by Albert Einstein’s general theory of relativity all the way back in 1915.
