Ultrasounds show mothers' drinking shrinks fetal brain

...andmaker. The authors say that while women's own reports of their drinking habits may not be entirely accurate, the study findings are consistent with other research on fetal alcohol exposure in animals and humans. "The provision of feedback on fetal development as revealed in ultrasonography may be a st...

Tiny polyps gorge themselves to survive coral bleaching

... British journal Nature. During the past decade, reports have multiplied of major bleaching events that have damaged, if not destroyed, large portions of the world's fragile coral reefs.
