SharkGuard gadgets work by harnessing sharks’ ability to detect electric fields. That could save the animals’ lives, a study suggests.
Honeybees flying over a sensor measuring atmospheric voltage sparked a look into how insect-induced static electricity might affect the atmosphere.
In experiments, bees tend to go to smaller numbers on the left, larger ones on the right. But the idea of a mental number line in animals has critics.
Bacterial cells shut down and become spores to survive harsh environments. An internal countdown signals when it’s safe for bacteria to revive.
