Activating a gene called AMPK in the nervous system induces the anti-aging cellular recycling process of autophagy in both the brain and intestine. Activating AMPK in the intestine leads to increased autophagy in both the intestine and brain. Matthew...
Researchers have discovered that the fear of predators causes flies to spend less time eating, more time being vigilant, have less sex, and produce fewer offspring
