Powerful computer models predict that winter temperatures in the polar regions of the world could rise as much as 10 degrees centigrade in the next hundred years, if no efforts are made to control production of carbon dioxide, methane and other gasses.

“With projections to the year 2100, we can show what will happen if we continue with business as usual—if we don’t do anything to curb emissions of greenhouse gasses,” said Warren M. Washington, senior research scientist for the National Cent

How will global warming affect life on Earth? Uncertainties about future climate change and the impact of human activity make it difficult to predict exactly what lies ahead. But the past offers clues, say scientists who are studying a period of warming that occurred about 55 million years ago.

Darwin may have been wrong about sex. Or at least too narrow minded

At the annual meeting of the American Association for the Advancement of Science, leading researchers and theorists in the evolution of sexual behavior will gather to present the growing evidence that Darwin’s idea of sexual selection requires sweeping revisions.

’’I don’t have a theory to address it all by any means,’

Physics gets strange when matter gets small. Take electrons orbiting the nucleus of an atom, for example. If they did so with the same dynamics by which planets orbit the sun, classical physics predicts the electrons would spiral toward the nucleus and crash into it in a fraction of a second. But that doesn’t happen.

At very low temperatures, classical physics fails to explain phenomena at tiny scales. This is when quantum mechanics kicks in. Scientists are now chilling materials to ne

The fact that infections among adults can increase the risk of heart attacks and strokes is now well established by several hundred scientific studies. Both heart attacks and strokes are expressions of arteriosclerosis (thickening of the arteries, previously termed hardening of the arteries). New research from the Section for Pediatric Cardiology in Lund indicates that infections can also contribute to the early development of arteriosclerosis even in childhood.

Austrian physicists report unusual light-metal interaction

A team under Professor Franz Aussenegg at the University of Graz in Austria is looking into unusual interactions between light and submicroscopic metal particles. The physicists’ findings represent a major advance towards the development of improved data storage media and optical sensors. They also confirmed theoretical predictions and merited publication in 13 international scientific journals. These are the impressive result
