March 7, 2013 For more than a century, neurons have been the superstars of the brain. Now researchers say that when they placed human versions of another type of brain cell into mice brains, the mice grew up to be faster learners. This supports the hypothesis that these glial cells — and not just better-known neurons — play an important role in learning.

March 4, 2013 More than 90 clinical trials have tested therapeutic vaccines in cancer patients, but the results have been a mixed bag. A recent study in mice suggests that changing a traditional ingredient in the vaccines could make a big difference.
March 1, 2013 Studies show that end-of-care is often futile. It doesn't always prolong lives, and it doesn't always reflect what patients want. But for families making decisions about loved ones, balancing the evidence and emotions can be wrenching.
