Cold temperature inversions actually help warm the Arctic
As the Earth warms, the change seen at high northern latitudes is greater than any other part of the planet a phenomenon known as Arctic amplification. A paper published this week in Nature Geoscience identifies another factor behind that amplification: a
Black Death genome revealed
The DNA of the Black Death bacterium has been sequenced, a development that could allow researchers to track how it evolved to become such a killer.

Falling satellite flips, putting U.S. at risk
A bus-sized NASA satellite about to fall to Earth has changed its orientation, throwing off earlier predictions about its descent and opening up the possibility that some debris will land in the U.S.
CERN (LHC) scientists 'break the speed of light'
If confirmed, the discovery would undermine Albert Einstein's 1905 theory of special relativity, which says that the speed of light is a "cosmic constant" and that nothing in the universe can travel faster.
That assertion, which has withstood over a c
Asteroid thought to kill dinosaurs may not be guilty
New data from space have cast into doubt the identity of the asteroid that led to the extinction of the dinosaurs. The current theory is that a large asteroid called Baptistina collided with another rock, throwing out huge fragments into the Solar System.

International scientists are expressing concern that cuts at Environment Canada could hobble a program monitoring ozone, a component of the atmosphere that protects living things from the sun's ultraviolet rays.
Glowing cats new tool in AIDS research
CHICAGO - U.S. scientists have developed a strain of green-glowing cats with cells that resist infection from a virus that causes feline AIDS, a finding that may help prevent the disease in cats and advance AIDS research in people.
Planet with 2 suns discovered
A planet that orbits two suns at the same time — just like Tatooine in Star Wars — has been found for the first time.
Dinosaur feather evolution trapped in Canadian amber
A study of amber found near Grassy Lake in Alberta - dated from what is known as the Late Cretaceous period - has unearthed a full range of feather structures that demonstrate the progression.
"We're finding two ends of the evolutionary development th
Fifty new exoplanets discovered
Astronomers using a telescope in Chile have discovered 50 previously unknown exoplanets. The bumper haul of new worlds includes 16 "super-Earths" - planets with a greater mass than our own, but below those of gas giants such as Jupiter.
Defunct NASA satellite to fall out of sky
NASA says the 20-year-old satellite will probably fall sometime between late September and October. Pieces of it could land anywhere in the six inhabited continents in a worldwide swath from south of Juneau, Alaska, to just north of the tip of South Ameri
