Eventually, Linus Pauling and Francis Crick, independently, explained this discrepancy by a slight additional coiling of the helices. Because of the non-integer screw, a shift by slight coiling facilitates their best packing. According to Crick, this is a nice example of symmetry breaking by a weak interaction. Voucher Codes.

Experts at Nasa remain unconvinced. They will live in the dome, located on barren land in Hawaii, for the next 12 months. The Nasa-funded project will allow the organisation to plan for a human mission to the Red Planet, which is expected to take between one and three years. The team will have to survive without fresh air and fresh food. Their diet will include powdered cheese and canned tuna and they will only have a small sleeping cot and desk inside their room.
Since scientists have known that a gene named FTO was related to obesity and people with higher BMIs Body Mass Index have been found to carry a variant of this gene. But despite this, it had not been known how or why FTO was related to obesity. Now, researchers at MIT and Harvard Medical School believe they have discovered that a faulty version of this gene causes energy from food to become stored as fat in the body rather than be burned, contributing to obesity.
But Nasa has already denied that anything is headed for us any time in September. Scientists have developed a way of storing vast quantities of information for up to a million years in a single molecule of DNA. The breakthrough could lead to digital archives of everything from ancient texts to Wikipedia changes being stored in the form of DNA that could in theory survive for hundreds of thousands of years without any loss of data.
Astronomers have detected a methane-shrouded world light years away that may hold the key to understanding how planets form in the dust clouds swirling around stars. The Gemini Planet Imager GPI attached to the Gemini South telescope in the Atacama desert, was built to discover faint, young planets orbiting bright stars — and in its first month of operation it found one.
The chemical precursors for making morphine and heroin have been produced by genetically-engineered microbes rather than poppy plants for the first time, raising the prospect that the most powerful painkillers known to science could be made from scratch in the lab. Currently all natural opiates, such as morphine and codeine, are manufactured from poppy plants farmed under licence. Researchers now believe these farms may one day be replaced by industrial vats of genetically engineered yeast fermenting in sugar solution. Astronomers have discovered the closest rocky planet outside our solar system, which is larger than Earth and a "potential gold mine of science data".
Using Nasa's Spitzer Space Telescope, scientists managed to confirm the existence of the planet, in a major milestone in space research.

Unfortunately, unlike Kepler b, the incredibly Earth-like planet that was discovered recently, this new planet, the catchily-named HD b, is far too close to its star to sustain life. Astronomers found the aurora light display around a brown dwarf 20 light years away. Scientists from Sweden have found a fossilised cocoon in Antarctica containing the world's oldest sperm.
The discovery of the fossilised sperm found inside the walls of a 50 million-year-old worm cocoon has been branded "remarkable" by scientists. The findings, published by The Royal Society, say that the specimen is the oldest animal sperm ever found. Nasa announced discovery of new planet seen as 'close cousin' to Earth.
Palaeontologists in China have found a close relative of the Velociraptor that has a well-preserved set of bird-like wings — and may have been just about to evolve into a bird. The skeleton is nearly complete and could offer clues to what Velociraptors actually looked like. The new find has wings with properly-layered feathers, the team reports. Though it is a dinosaur, it looks more like a turkey or vulture. All of the pictures since then have been produced by stitching together different pictures into a full image of the globe.
The new picture is a composite, of three separate images, but each of those images showed the whole planet. The camera takes ten images through the colour spectrum — going all the way from ultraviolent to infrared — and to make the new picture Nasa combined the red, green and blue pictures. The photo was taken on July 6, , and mostly shows North and Central America. Scientists have warned that a new strain of a 'flesh-eating' bug is spreading globally, and has contributed to a rise in disease cases in the UK.
The group A streptococcus bacteria typically causes relatively minor infections, such as tonsilitis, and is treated readily with antibiotics. However, in severe cases of invasive infection, the bacteria can cause necrotising fasciitis - a condition which destroys and eats away at body tissue, and causes pneumonia and blood poisoning. A bizarre extinct creature that has mystified scientists since its m-year fossil was first unearthed more than a century ago has finally revealed its teeth — placing it centre stage in the evolution of many complex life-forms living today.
Hallucigenia, which owes its name to its unworldly appearance, was so odd that scientists initially confused its top from its bottom and its head from its tail. However, a study has now unequivocally identified its mouth, complete with a fearsome ring of sharp teeth. Five previously hidden supermassive black holes have been discovered by British astronomers, leading to speculation that the universe could contain millions of the mysterious monsters which chew up everything that comes close to them.
The New Horizons craft has sent back stunningly detailed pictures of Pluto taken just before it began its historic flyby, only months after Nasa was celebrating seeing the dwarf planet in colour at all. In April, Nasa released pictures showing just two tiny, imprecise dots — Pluto and its largest moon, Charon, though they wouldn't have been recognisable to anyone but experts. Now, the agency has released finely-detailed images of the dwarf planet, showing its geological features and its large, plain "heart".
The test is based on the rapid and simultaneous detection of the hundreds of different antibodies that the human immune system makes when the body is invaded by viruses ranging from influenza and herpes to HIV and Ebola. The fossilised skeleton of the dog-sized creature, a theropod dinosaur, is described as a cousin of the giant tyrannosaurus rex and is believed to be the earliest specimen of a Jurassic era dinosaur ever to walk the Earth. Described as the "find of a life-time" it was discovered on Lavernock beach near Penarth in the Vale of Glamorgan by two fossil-hunting brothers, Nick and Rob Hanigan after storms in spring Bears have been seen catching and eating dolphins for the first time ever, after the marine mammals were left stuck in the Arctic Ocean because of global warming.
It marks the first time that bears have been seen killing and eating dolphins.
Usually, the dolphins only go up north during the warmer summer — but this year they have arrived in spring. The bears catch the dolphins in a similar way to the seals that they usually eat. Both animals keep holes in the ice which they use to come up and breathe from — at which point, if the bear is lucky, it will snatch them up and eat them. Now a mast, taller than the Eiffel Tower, has been built deep in the heart of the forest — amid jaguars, snakes and giant trees — to monitor chemical changes in the air that could shed new light on global climate change.
Until now the division between the simple cells of microbes such as bacteria from the more complicated cells of animals and plants has been so abrupt and absolute that it was difficult to see how one could have evolved from the other. However, researchers have now found a new microbial species that sits between the two branches of life, and which appears to be a living descendent of the last common ancestor of both the simple microbial life-forms and the complex life we see all around us. The US government is developing highly-advanced killer robots and we must decide whether we support or oppose them, a leading computer scientist has said.
Aeon for Friends
Lethal autonomous weapons systems, or LAWS, are being developed that could eventually become super-powerful and will not be able to ethically choose who should live or die, Stewart Russell, a professor of computer science at the University of California, Berkeley has warned. In the journal Nature, Russell likened the power to nuclear weapons — and said that just as physicists eventually had to take a position on the use of that technology to kill, so should AI specialists and others.
The agency hopes that the probe will be able to scour Europa to check whether the thick layer of ice on its surface obscures an ocean, which they hope could contain conditions for living things. It has chosen nine instruments from a shortlist of Early humans migrated out of Africa more than 60, years ago through Egypt rather than crossing the shallow sea that separated Ethiopia from the Arabian Peninsula as some archaeologists have suggested, a study of the DNA of modern people has found.
Scientists have long argued about which of the two migratory routes the first humans took when they emerged from Africa to colonise the Middle East, Asia and other parts of the globe. Now a study of present-day genomes of north-east Africans suggests the northern route through Egypt and the Sinai was more likely. The study analysed the genomes of Egyptians and Ethiopians and compared their DNA to people currently living in Eurasia and to other parts of Africa.

It concluded that the ancient migratory route through the Sinai Peninsula has left its mark on the DNA of people living in Egypt today, scientists said. Ray Kurzweil, an inventor and director of engineering at Google, said that in the s the implants will help us connect to the cloud, allowing us to pull information from the internet. Information will also be able to sent up over those networks, letting us back up our own brains.
