    To Make Mice Smarter, Add A Few Human Brain Cells

    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.

    Morning-After Pills Don't Cause Abortion, Studies Say

    Emergency contraceptives like Plan B and ella are effective at preventing pregnancy after unprotected sex. Claims that the pills are tantamount to abortion, however, aren't supported by science, say researchers. The only way the drugs work is by stopping a woman's body from ovulating.
