Astronomers poised to apply novel way to look for comets beyond Neptune

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

Next-generation solar cells could put power stations in space

RIT scientists develop nanomaterials for NASA program

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.

Benefits of treating behavioral, functional problems caused by Alzheimer’s disease

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

Coronal activity may be ’buried alive’ in red giant stars, say Colorado researchers

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

New role for tamoxifen as fertility drug for breast cancer patients?

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

Missing link found between old and young star clusters

One and a half billion years ago the small, inconspicuous galaxy Messier 82 (M82) almost smashed into its large, massive neighbour galaxy Messier 81 (M81), causing a frenzy of star formation.

New research by astronomers from the Universities of Cambridge and Utrecht, Netherlands, has now discovered an elusive phenomenon in this violent “starburst” area. About 100 star clusters have been discovered that are believed to be the ancestors of the so-called “globular clusters” thought to be the ol
