Baby manta rays hunker down close to coasts before facing the open ocean's dangers
Giant manta rays can grow up to nine meters (30 feet) long with a disk size of seven meters (23 feet) across and weigh up to 2,000 kg (4,400 pounds). This size leaves them with very few natural enemies once they reach adulthood ...

Mirror-image molecules are difficult to separate from their counterparts, but a new catalytic method might be the answer
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team ...
Atomic memory keeps distant ions entangled for about 10 seconds
Quantum networks, systems that connect devices and allow them to exchange information encoded in the quantum states of particles, could enable more secure communications. To build these networks, physicists need to devise ...
Bering Sea heat wave linked to a surprising boom in the number of hybrid crabs
