Phys.org / Do animal behavior experiments give a distorted view of cooperation?

When biologists study cooperation in animals, they usually offer just a single task at a time. But what happens when animals can choose among several opportunities to work together? Biologists at Utrecht University discovered ...

Phys.org / Thirsty desert lizards inspire a new water-harvesting system

When the desert horned lizard (Phrynosoma platyrhinos) is thirsty, it cannot just lap up water or scoop it up like a bird because it lives in environments where water is extremely scarce. Typically, it's found in damp soil ...
