Our ancestors were making stone tools even earlier than we thought—some 700,000 years older. That’s the finding of the West Turkana Archaeological Project (WTAP) team—co-led by Stony Brook University's Drs. Sonia Harmand and Jason Lewis—who have found the earliest stone artifacts, dating to 3.3 million years ago, at a site named Lomekwi 3 on the western shore of Lake Turkana in northern Kenya.
Removing accumulated mutant p53 protein from a cancer model showed that tumors regress significantly and survival increases. This finding, by an international team of cancer researchers led by Ute Moll, MD, Professor of Pathology at Stony Brook University School of Medicine, is reported in a paper published advanced online May 25 in Nature.
