Duke University Medical Center and National cancer institute scientists have discovered that a novel genetic alteration - a second copy of an entire gene - is a cause of familial chordoma, an uncommon form of cancer arising in bones and frequently affecting the nervous system.

CLAIMS that cattle and sheep are responsible for 10.9 per cent of Australia's greenhouse gas emissions have been called into question after scientists discovered considerable variation in the amount of methane produced by individual animals.

NASA scientists have figured out how to extract water from lunar soil. Their approach is as easy as using a microwave oven.

Australian researchers are developing ways of turning unwanted waste into viable and marketable products.

Australian-born Elizabeth Blackburn, along with British-born Jack Szostak and American Carol Greider, have won the Nobel prize for medicine or physiology.

Scientists in Toronto, Ontario are waiting in eager anticipation tonight, to hear the announcement of this year's Nobel Prize in Medicine, since two of their own are favorites for the...

When NASA announced last month the finding of water ice in several impact craters on Mars , and either water or hydroxyl widely dispersed on the moon 's surface, the solar system became a little more familiar because it seemed a tad more hospitable to life as we know it on Earth.But is that because the rest of the cosmos has much in common with Earth or vice versa? Water, the unique molecule that cradles and nurtures life here, is apparently common and perhaps abundant in the solar system. Observational evidence suggests that water as a solid, liquid or gas is present at the poles of Mercury, within the thick clouds of Venus, on Mars, inside asteroids and comets, and on Jupiter, Saturn, Uranus and Neptune. Scientists also have speculated that Jupiter's moons Europa , Ganymede and Callisto have vast subsurface oceans of liquid water. They have also detected through spectroscopy water frost on Pluto's moon, Charon. Of course, scientists have known that H 2 O also seems to be ubiquitou

A derivative of cholesterol is necessary for the formation of brain cells, according to a new study. The results can help scientists to cultivate dopamine-producing cells outside the body.

(Duke University) As scientists work toward making genetically altered bacteria create living 'circuits' to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way.

Islands are often the playgrounds of imaginary scientists, from Dr. Moreau to the researchers on the TV show Lost. But this place is real: an island where every single plant species has had its DNA analyzed and cataloged.
