In results presented this week at the 2003 meeting of the American Astronomical Society (AAS) in Seattle, astrophysicist Greg Aldering and colleagues report that their supernova factory project has discovered an unprecedented 34 new supernovae in its first year. The accomplishment would not have been possible without the National Science Foundation (NSF) – supported high performance wireless network link to Palomar Observatory. “This has been the best rookie year for any supernova search pro
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 today (Wednesday 8 January) 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
ESAs Rosetta will be the first mission to orbit and land on a comet, one of the icy bodies that travel throughout the Solar System and develop a characteristic tail when they approach the Sun. Rosetta is scheduled to be launched on-board an Ariane-5 rocket in January 2003 from Kourou, French Guiana. A decision on the launch date will be taken by Tuesday 14 January (see Arianespace press release N° 03/02 of 7 January 2003 or at http:www.arianespace.com).
The mission’s target is Comet Wi
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
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
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 bears 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
