Memes about animal resistance are everywhere — here’s why you shouldn’t laugh off rebellious orcas and sea otters too quickly

A few marine mammals in apparent revolt pushed meme-makers into overdrive. But a scholar who thinks about justice and human-animal relations suggests something deeper is behind the schadenfreude.

A changing climate, growing human populations and widespread fires contributed to the last major extinction event − can we prevent another?

New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.
Graphic novels can help make math and physics more accessible for students, parents or teachers in training. Metamorworks/iStock via Getty Images

3 reasons we use graphic novels to teach math and physics

Graphic novels pair text and images to explain complex topics – from thermodynamics to abstract math – without alienating STEM-averse students.
