Researchers use origami to advance cardiac catheters

A graduate student in the University of Georgia College of Engineering is turning to the ancient Japanese art of origami for inspiration as he designs a novel cardiac catheter. Austin Taylor is developing a device that’s small enough to fit on the tip of a...

Super-bright supernova appears to have exploded twice

Supernovae are among the most violent phenomena in the universe. They are huge explosions which put an end to the lives of certain types of stars. These explosions release immense amounts of energy, so much that sometimes we can see them from Earth with the naked eye,...

Researchers develop placenta-on-a-chip

Researchers at the University of Pennsylvania have developed the first placenta-on-a-chip that can fully model the transport of nutrients across the placental barrier. The flash-drive-sized device contains two layers of human cells that model the interface between...

Protein interaction drives muscle atrophy
