New microfluidic chip replicates muscle-nerve connection

MIT engineers have developed a microfluidic device that replicates the neuromuscular junction—the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and ...

Injured jellyfish seek to regain symmetry, study shows

Self-repair is extremely important for living things. Get a cut on your finger and your skin can make new cells to heal the wound; lose your tail—if you are a particular kind of lizard—and tissue regeneration may produce ...

Elephants sing low the same way humans do

(Phys.org) -- Mammals produce sounds in two ways, either via the flow of air over vocal folds (vocal chords), as in humans and many other mammals, or via active muscular contractions as in the cat’s purr. Until now no ...

DNA origami to scale-up molecular motors

Researchers have successfully used DNA origami to make smooth-muscle-like contractions in large networks of molecular motor systems, a discovery which could be applied in molecular robotics.

A new mechanism for how animal cells stay intact

Almost eight years ago, Stanford University bioengineer Manu Prakash was looking for a way to watch every cell in an adult living, behaving animal in elaborate detail. He searched the catalog of life and happened upon the ...

Cornering endangered species

As certain species decline in number, the geographic areas they inhabit also shrink. Still, even with less space to occupy, these decreasing populations manage to remain locally abundant.
