ScienceDaily (Nov. 5, 2010) Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests.

Working with mathematicians, anthropologists and molecular biologists, Martin has long sought to integrate evolutionary information derived from genetic material in various species with the fossil record to get a more complete picture.

ScienceDaily (Mar. 8, 2010) Rapamycin, a drug that keeps the immune system from attacking transplanted organs, may have another exciting use: fighting Alzheimer's disease. The drug -- a bacterial product first isolated in soil from Easter Island -- rescued learning and memory deficits in a mouse model of Alzheimer's, a team from The University of Texas Health Science Center at San Antonio reported on Feb. 23.

LONDON (Reuters) - Eating disorder campaigners criticized British model Kate Moss on Thursday for saying she backed the motto "Nothing tastes as good as skinny feels," a slogan popular with pro-anorexia websites.

Health experts said 35-year-old Moss, renowned for her waif-like appearance, had been irresponsible to make the comment, arguing girls could be influenced by the style icon.

Asked in an interview with fashion news website WWD if she had a motto, Moss was quoted as saying: "There are loads. There's 'Nothing tastes as good as skinny feels.' That's one of them. You try and remember, but it never works."

Though coordinating eight separate arms might seem a tricky task for an octopus brain, whats really demanding is controlling the arms flexible, infinitely variable movements. Now researchers have figured out part of their secret.

Unlike us, specific regions of an octopus motor cortex dont correspond to specific parts of its body. Instead, each region controls different parts at different times. Their motor neural network seems as flexible as their bodies a phenomenon that expands the range of neurophysiological possibility, and could refine the design of arm-flexing robots.
