...degenerative process started by sending aberrant signals to the bone? "At this point, it would be a mistake to fight bitterly over whether osteoarthritis starts in the bones or cartilage, because in the end there may be different forms of the disease," says Dr. Bjorn Olsen, a cell biologist at Harvard University. "In some cases, it may start in the bone. In others, it might start in the cartilage...
Sardinians in general, it turns out, have a special propensity for living long. According to research conducted by Sardinian molecular biologist Luca Deiana, the island has the world's highest documented percentage of people who have passed the century threshold--although the same claim has been made about the Japanese island of Okinawa. Of 1.6 million Sardinians, at least 220 have reached 100, twice the typical ratio. Five of the world's 40 oldest people live on the island, and until the January death of Antonio Todde at 112, Sardinia boasted the oldest of them...
...head of the University’s anthropology department, Ernest Hooton, was a member of the American Eugenics Society, which remained active until the 1970s. The society’s advisory board included nine other Harvard faculty members and its vice president, Charles Davenport, was a Harvard-trained biologist...
Three studies presented in the journal Science last week help resolve all these questions. The first paper addresses where the wolf-to-dog transformation took place. Biologist Jennifer Leonard, at the Smithsonian's National Museum of Natural History in Washington, and her co-authors collected the remains of dogs buried in North, Central and South America before Columbus showed up (and thus before interbreeding with European dogs could have taken place) and sampled their mitochondrial DNA, or MTDNA, which is passed on only from the mother. If these ancient American dogs had arisen locally, their MTDNA should have been similar...
...calculated that it takes 2 to 5 lbs. of anchovies, sardines, menhaden and the other oily fish that comprise fish meal to produce 1 lb. of farmed salmon, which he says makes no sense in a world trying to increase the amount of available protein. Kentucky State University biologist James Tidwell, 47, a former president of the World Aquaculture Society, points out, however, that wild salmon are bigger eaters than that--consuming at least 10 lbs. of fish to add 1 lb. in weight--and argues that harvesting large amounts of short-lived species like menhaden is no more harmful...
