Calorie restriction: longer life, fewer memories?
PRINCETON (US)—Decreasing calorie intake and tweaking the activity of the hormone insulin are two methods long known to increase lifespan in a wide range of organisms. Now, biologists have uncovered evidence that these mechanisms also have an impact on learning and memory. (more…)

Carbon cycle snowballed out of control
PRINCETON (US)—New evidence uncovered by a team of geologists suggests that an episode 720 million years ago called “snowball Earth,” which may have covered the continents and oceans in a thick sheet of ice, produced a dramatic change in the carbon cycle. (more…)
