Looking for life below the bottom

Article Abstract:

Marine researchers are analyzing samples filtered from water trapped below the ocean floor 3,500 feet below the surface for signs of life. Simple organisms may live in fractures within the rock, completely separate from the ocean water. Organic material in this isolated environment may be similar to that which might be found on other planets.

Catchy carbon: What Floyd Landis has in common with ocean sediment

Article Abstract:

The medical researchers at the U.C.L.A. Olympic Laboratory have developed the first definitive screen for synthetic testosterone, a popular anabolic steroid banned by most sports organizations since the 1970s, by modifying marine chemist John Hayes's method to examine the carbon atoms in athletes' urine. The efficacy of the new test, also called as the carbon isotope ratio (CIR) test, is described.

Deserting the Sahara: Dying plants harvest harsh surprises from climate change

Article Abstract:

The Sahara was once a lush, green region in North Africa until about five thousand years ago, when it abruptly became desert. New climatological research suggests that plants played a significant role in accelerating the process of desertification.
