Phys.org / Scientists solve the puzzle of directional hearing underwater

When underwater, humans cannot determine where a sound comes from. Sound travels about five times faster there than on land. That makes directional hearing, or sound localization, nearly impossible because the human brain ...

Phys.org / Scientists discover new behavior of membranes that could lead to unprecedented separations

Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to ...

Phys.org / 'Two-for-one' fission aims to improve solar cell efficiency

Singlet fission occurs when an organic molecule absorbs one photon of light, then splits that light's energy in two—a doubling effect that has the potential to improve the light-harvesting efficiency in solar cells, assuming ...

Phys.org / Membrane protein analogs could accelerate drug discovery

Many drug and antibody discovery pathways focus on intricately folded cell membrane proteins: when molecules of a drug candidate bind to these proteins, like a key going into a lock, they trigger chemical cascades that alter ...
