Exposure to Toxins Makes Great Granddaughters More Susceptible to Stress

b2ap3_thumbnail_sleepypups-ADJUST.jpgScientists have known that toxic effects of substances known as endocrine disrupting chemicals (EDCs), found in both natural and human-made materials, can pass from one generation to the next, but new research shows that females with ancestral exposure to EDC may show especially adverse reactions to stress.

Grasshopper Mice Are Numb to the Pain of the Bark Scorpion Sting

The painful, potentially deadly stings of bark scorpions are nothing more than a slight nuisance to grasshopper mice, which voraciously kill and consume their prey with ease. When stung, the mice briefly lick their paws and move in again for the kill.
