Toward Faster Tests To Identify Carcinogens And Other Environmental To
After years of frustration with traditional methods for testing the toxicity of chemicals in the environment, scientists are working to adapt faster, simpler screening methods that do not require animals, now used by the pharmaceutical industry to identify potential drug candidates, according to a new article. The Planet, The Galaxy And The Laser
On the night of July 21, ESO astronomer Yuri Beletsky took images of the night sky above Paranal, the 2600-meter high mountain in the Chilean Atacama Desert home to ESO's Very Large Telescope. The amazing images bear witness to the unique quality of the sky, revealing not only the Milky Way in all its splendour but also the planet Jupiter and the laser beam used at Yepun, one of the 8.2-meter telescopes that make up this extraordinary facility. Radiient Technology Touts Wireless Speakers for Audiophiles
Wireless speakers sound like a great idea, but so far no one has made them work very well -- sound quality and latency are just too problematic. Now a new ultra-wideband, mesh-networked wireless-speaker technology aims to fix that. Venlafaxine Extended-release Effective For Patients With Major Depress

Without sex, these animals lack many of the ways in which sexual animals adapt over generations to survive in their natural environment. Storm Warning: Advancements in Marine Communications and Forecasting
This presentation, created in 2000 on the 25th anniversary of the sinking of the S.S. Edmund Fitzgerald, looks at developments in marine communications and forecasting since that disaster on Lake Superior. Some of the topics include forecast and warning definitions, numerical weather prediction, advances in scientific understanding, and radars and satellites.

Hematopoietic stem cells (HSCs) are one of the few cell types able to resist infection with HIV-1 despite expressing the cell surface molecules to which HIV-1 binds before entering a cell. In a study that appears in the February issue of the Journal of Clinical Investigation, researchers from Harvard Medical School, Boston, show that HSC expression of a protein known as p21Waf1/Cip1/Sdi1 (p21) is required for HSCs to be resistant to infection with HIV-1. Discovery Of Compound Could Enhance Cancer Treatments With Fewer Side
