Phys.org / Photonic 'ski jumps' efficiently beam light into free space

Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, and is difficult to transmit ...

Phys.org / Corpses leave clues behind in the soil long after they're gone

It is not uncommon for a body to be moved after a murder, usually to hide or eliminate evidence. And while the Arizona desert may seem like the perfect place to commit such a crime, a new study shows that a cadaver can still ...

Phys.org / Still standing but mostly dead: Recovery of dying coral reef in Moorea stalls

In April 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. This "bleaching" event reduced live coral populations ...
