Clioquinol has shown promise as a potential treatment for Alzheimer's disease in recent studies in mice and humans. Apparently through chelation, it interferes with the creation...

New tooth enamel dating technique could help identify disaster victims

...l. Scientists can relate the extensive atmospheric record for carbon-14 to when the tooth was formed and calculate the age of the tooth, and its owner, to an accuracy of within about 1.6 years. "Unlike most other tissue, dental enamel doesn't turn over," said Bruce Buchholz of LLNL's Center for Accelerator ...

Oxygen increase caused mammals to triumph, researchers say

...TAWAY, N.J. The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet, according to Paul Falkowski, Rutgers professor of marine science an...
