A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it help mothers or young survive?
Melting glaciers may mix up waters more than we thought
As marine-terminating glaciers melt, the resulting freshwater is released at the seafloor, which mixes with salty seawater and influences circulation patterns. As the oceans warm, it's growing increasingly important to study this process.
