Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between �true� neural stem cells and similar, but less potent versions.

Also, gardening not only gets children off of the couch and outdoors, but it also counts as physical activity.

Los Angeles - Angiogenesis inhibitors, drugs that block a tumor's development of an independent blood supply, have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy.

This was especially true for women who breathed polluted air during the first trimester or during the last months and weeks of pregnancy.
