Male baboons with female friends live longer  

Opposite-sex friendships can have non-romantic benefits. And not just for people, but for our primate cousins, too. A 35-year study of 542 baboons finds that males that have close female friends have higher rates of survival. Previous studies have assumed that males befriend females to protect their offspring, or to boost their chances of mating later on. But the new study points to an additional benefit: female friends may help them live a longer life.

Corona-induced CO2 emission reductions are not yet detectable in the atmosphere  

The impact of the corona pandemic will reduce worldwide carbon dioxide emissions by up to eight percent in 2020. Cumulative reductions of about this magnitude would be required every year to reach the goals of the Paris Agreement by 2030. Measurements now revealed that concentration of carbon dioxide in the atmosphere has not yet changed due to the estimated emission reductions.

Part of the secret to human longevity may lie in chemical changes to our DNA that slowed the rate of aging after human ancestors diverged from chimps.
