LA JOLLA, CA — A team of scientists at the Salk Institute for Biological Studies think they know how many-if not most-living organisms answer this question. They recently showed that when food supplies dwindle, mammals, fruitflies, or frogs probably activate the same ancient cell signaling pathway in order to conserve energy.
"This paper provides the first direct biochemical explanation for how cell growth is inhibited under conditions when nutrients are low," reports Shaw. "This very simple bio-circuit is literally the bare bones signal that most organisms use to say, 'We've got food!' " Full story HERE.
