Researchers grew hair from human induced pluripotent stem cells, the first step in developing a possible new treatment for hair loss.

Lions in Tanzania's Serengeti National Park may be contracting canine distemper from wild hyenas and jackals as well as domesticated dogs.

The galectin proteins (green) expressed in snail hemocytes—which are equivalent to human white blood cells—bind to the parasitic worm that causes schistosomiasis in people.

Blood vessels (green) form near the aorta of a developing mouse heart (lining in blue).

A drop in sea level caused the southern Great Barrier Reef to slow its growth 2,000 years ago.

Whale sharks, the largest fish in the ocean, often attract fellow travelers like tuna.

A newly identified bone stem cell (red) shown inside a mouse femur appears to be important in skeletal development.

Hoopoe birds (Upupa epops) coat their eggs in a bacterial secretion that protects the embryos from infection.

Bright borage flowers attract bees and are thus often planted by gardeners to attract the insects to pollinate their plots.
