You’re Drunk, Toadlet
Most frogs and toads are excellent jumpers, taking off and landing with a control and grace that rivals elite athletes. Not so for the pumpkin toadlet. These species have become Keep reading
Swimming in Complex Fluids
Bacteria like E. coli swim using flagella, helical filaments attached to biological motors on their bodies. By rotating the flagella, the bacterium generates thrust that propels it forward. Oddly, though, Keep reading
Recreating Flocks
Birds, fish, and other creatures form amazing, undulating swarms of individuals. How these collectives comes together and move continues to fascinate scientists. Here, researchers look at simple particles with two Keep reading
Flying With Geese
Some people fly with geese to train them for wind tunnel tests, and some people fly with them to teach them safer migratory paths. Today’s video focuses on the latter, Keep reading
Moving By (Intestinal) Wave
A word of warning: today’s post includes visuals of digestion taking place in (non-human) embryonic intestines. Our bodies rely on waves driven by muscle contractions to move both fluids and Keep reading
