...accommodation” policy, where restaurants would designate separate smoking and non-smoking areas. This type of partial regulation does not go far enough to give restaurant employees a smoke-free environment. Research conducted by the School of Public Health at the University of California Berkeley, found that even in restaurants where customers may only smoke in designated areas, staff exposure to secondhand smoke was still up to half that of staff in restaurants with no smoking restrictions at all. This study included participants who worked in res taurants with separate ventilation systems for smoking and non-smoking areas...
...maybe all these learned experts are barking up the wrong evolutionary tree after all. At least one equally eminent paleontologist, Tim White of the University of California, Berkeley, disputes the assertion that Toumai derails the standard evolutionary family tree, let alone plants a bush in its place. The discovery is a tremendous accomplishment, he says. "This fossil is the closest we've got to the common ancestor. But dentally, it's just like Ardipithecus, except for a few minor characteristics." The mix of primitive and more advanced traits leaves him similarly unimpressed, since such mixing has been seen in various...

...Brown and his endangered breed, let's entertain two arguments in favor of eating meat. One is that it made us human. "We would never have evolved as large, socially active hominids if we hadn't turned to meat," says Katharine Milton, an anthropologist at the University of California, Berkeley. The vegetarian primates (orangutans and gorillas) are less social than the more omnivorous chimpanzees, possibly because collecting and consuming all that forage takes so darned much time. The early hominids took a bold leap: 2.5 million years ago, they were cracking animal bones to eat the marrow. They...
...causing all the buzz is 55 Cancri, about the size and age of our sun, located just 41 light-years away. This is not the first time a planet has been seen orbiting the star. In 1996 Geoffrey Marcy, a professor of astronomy at the University of California, Berkeley, and astrophysicist Paul Butler of the Carnegie Institution of Washington spotted a different Jupiter-size world circling 55 Cancri in a close-up orbit just 10 million miles from the solar fires--closer than little Mercury orbits our own sun. All told, astronomers have found about 90 big planets circling many...
