New research on a 45,000-year-old Siberian thighbone has narrowed the window of time when humans and Neanderthals interbred to between 50,000 and 60,000 years ago, and has shown that modern humans reached northern Eurasia substantially earlier than some scientists thought.
While most colleges and universities in the National Collegiate Athletic Association (NCAA) have created programs to help diagnose and treat concussions sustained by their athletes, many do not fully meet the NCAA’s standards, according to new work by Harvard researchers.
The report, the first-ever comprehensive examination of how colleges and universities have complied with the NCAA Concussion Policy and Legislation, is based on a survey sent to all 1,066 NCAA member institutions, 907 of which responded. Read more about Mixed results in report on concussions
Mammoth DNA in recovered cells frozen for thousands of years is likely too fragmented to clone an animal, according to Harvard geneticist George Church. So he’s working instead to engineer one genetically from a close relative, the Asian elephant. Read more about Behold the mammoth (maybe)
When you think of the Large Hadron Collider at CERN in Switzerland, you may think of cutting-edge equipment and particles circling unimaginably fast, colliding into each other to make bosons and other elements of the secrets of the universe.
But you may not think of the people.
Of course they’re there, and essential — thousands of scientists and support personnel, including Harvard physicists and students, some of whom played important roles in the 2012 discovery of the Higgs boson, the heaviest and most elusive particle discovered so far.

Harvard stem cell researchers announced today that they have made a giant leap forward in the quest to find a truly effective treatment for type 1 diabetes, a disease that affects an estimated 3 million Americans at a cost of about $15 billion annually. Read more about Giant leap against diabetes
