Unless the pace of global warming is abated, polar bears could disappear within 100 years, says a University of Alberta expert in Arctic ecosystems.

While it has been known for some time that the polar bear is in trouble, new research shows that Arctic ice–the polar bear’s primary habitat–is melting much faster than scientists had believed, says U of A biologist Dr. Andrew Derocher.

“The climate predictions coming out are showing massive changes in sea-ice distribution,” sa

Lawrence Livermore National Laboratory astronomers are major partners in a scientific collaboration that will conduct an extremely novel search for small, comet-like bodies in the outer solar system using four half-meter telescopes. The work was described today at the winter meeting of the American Astronomical Society.
Rather than look for the light reflected directly by these objects (as is customary astronomy practice), this project will search for those very rare moments when one of these ob

Someday, large-scale solar power stations in space could beam electricity to the surface of the moon, the earth and other planets, decreasing our dependence on a dwindling fossil-fuel supply.

Scientists at Rochester Institute of Technology are developing the next generation of solar cells, advancing the technology that could put a solar power system into earth’s orbit.

A class of drugs known as cholinesterase inhibitors has a significant impact on behavioral problems and the ability to perform everyday tasks in patients with Alzheimer’s disease, according to a study led by researchers at the San Francisco VA Medical Center (SFVAMC) and UCSF.

The study, an analysis of data from multiple small studies, appears in the January 8, 2003 issue of the Journal of the American Medical Association. Known as a meta-analysis, the study applied sophisticated statistical

When Earth’s sun expands into a red giant star in roughly five billion years, long after Earth has become uninhabitable, the hydrogen core will be burned out and the bloated outer shell will be cool and murky.

But according to new research by the University of Colorado at Boulder, such red giants still retain surface magnetic storms and coronas — the very hot and patchy outer atmosphere of the sun and sun-like stars — at temperatures of millions of degrees Fahrenheit that often signal

US fertility experts have discovered a potential new role for the wonder drug tamoxifen – helping breast cancer patients to have babies by IVF.

In a study published in Europe’s leading reproductive medicine journal Human Reproduction[1], researchers from New York’s Cornell University report the first IVF pregnancy to result from the use of tamoxifen as an ovarian stimulant.

In a study of 12 breast cancer survivors they found that stimulating the ovaries with a short, car
