Symmetry breaking during flapping generates lift

(Phys.org)—A small, translucent sea slug called Clione antarctica swims through the cold waters near the polar regions by flapping its wings. At the same time, tiny cilia that circle the sea slug's body in three bands may ...

New large optically bright supernova remnant discovered

Astronomers have reported the discovery of a new galactic supernova remnant (SNR) in the Cepheus constellation. The newly detected SNR is relatively large and optically bright, but faint in radio and X-ray bands. The finding ...

Actin 'avalanches' may make memories stick

If you're on skis, you want to avoid avalanches. But when the right kind happen in your brain, you shouldn't worry. You won't feel them. They're probably to your benefit.

Acoustic waves can monitor stiffness of living cells

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and investigate how stiffness changes ...
