Vampire bats’ bloody teamwork
Vampire bats are the only mammals that feed exclusively on blood. The way they manage to do that offers us some remarkable insights into evolution.
Herring larvae could benefit from an acidifying ocean
Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that’s bad news for fish, including commercially important species. But not all fish respond the same way.
Small birds discern threat level of enemies
