From wrapping paper and greeting cards to party favors and ornaments, millions of everyday items sparkle due to glitter. And while these shimmering objects are festive and eye-catching, they’re harming our planet and contributing to climate change. Environmental science researcher Claire Gwinnett PhD explains how.

Just like humans, fish have social networks too — and these could be key to helping protecting them and the coral reefs where they live, says marine biologist Mike Gil.

How do color-blind cephalopods — octopus, squid and others — achieve such a good color match when they camouflage? (in short: amazing, distributed brains).
