Darkness blankets the icy north in the winter, but tiny Arctic marine creatures are guided by the light of the moon. Researchers say the creatures' regular vertical migrations could help store more carbon deep in the ocean.
A nursery ground for sand tiger sharks was recently discovered in Long Island's Great South Bay. Researchers from the Wildlife Conservation Society's New York Aquarium say this find will help them better protect the vulnerable animals.
In Rebecca Boyle's essay "The Health Effects of a World without Darkness," in The Best American Science and Nature Writing 2015, she talks about ways that light pollution both keeps us from seeing the stars that all our ancestors saw and throws animals off their migration patterns.
Researchers from Linnaeus University closely examined migrating patterns of pike in the Baltic Sea and found that timing is the key to survival.
