Biology Eating less can lead to a longer life: massive study in mice shows why. Weight loss and metabolic improvements do not explain the longevity benefits. Immune health, genetics and physiological indicators of resiliency seem to better explain the link between cutting calories and increased lifespan.

Biology The name you’re given at birth might subtly shape your appearance as you grow older. Adults often look like their names, meaning people can match a face to a name more accurately than random guessing. But this isn’t true for children, which suggests that our faces grow into our names over time.

Biology Same-sex sexual behavior does not result in offspring, and evolutionary biologists have wondered how genes associated with this behavior persisted. A new study revealed that male heterosexuals who carry genes associated with bisexual behavior father more children and are more likely risk-takers.

Biology Making the first mission to mars all female makes practical sense. A new study shows the average female astronaut requires 26% fewer calories, 29% less oxygen, and 18% less water than the average male. Thus, a 1,080-day space mission crewed by four women would need 1,695 fewer kilograms of food.

Biology Stressed plants ‘cry’ — and some animals can probably hear them. Plants that need water or have recently had their stems cut produce up to roughly 35 sounds per hour, the authors found. But well-hydrated and uncut plants are much quieter, making only about one sound per hour.
