Light-activated skeletal muscle engineered (w/ Video)
Many robotic designs take nature as their muse: sticking to walls like geckos, swimming through water like tuna, sprinting across terrain like cheetahs. Such designs borrow properties from nature, using engineered materials ...

Researchers discover that stem cell marker regulates synapse formation
Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, ...

Bats use blood to reshape tongue for feeding
Nectar-feeding bats and busy janitors have at least two things in common: They want to wipe up as much liquid as they can as fast as they can, and they have specific equipment for the job. A study in the Proceedings of th ...

Regenerated lizard tails are new, but not replicates, researchers find
Just because a lizard can grow back its tail, doesn't mean it will be exactly the same. A multidisciplinary team of scientists from Arizona State University and the University of Arizona examined the anatomical ...

Light now in sight: Control of a 'blind' neuroreceptor with an optical switch
When nerve cells communicate with one another, specialized receptor molecules on their surfaces play a central role in relaying signals between them. A collaborative venture involving teams of chemists based at Ludwig-Maximilians-Universitat ...

Perfect micro rings woven from muscle fibers: A biological model system that dead-ends in 'absorbing state'
Supplied with sufficient energy, a freight train would ride the rails as far as they go. But nature also knows systems whose dynamics suddenly turn into a kind of endless loop. Like in a hamster wheel, a train ...

Simple chemical cocktail shows first promise for limb re-growth in mammals
Move over, newts and salamanders. The mouse may join you as the only animal that can re-grow their own severed limbs. Researchers are reporting that a simple chemical cocktail can coax mouse muscle fibers ...
