Fish Sensory Organ Duplicated for Submarines
Fish use a row of specialized sensory organs along the sides of their bodies, called lateral lines, to hunt for prey, alert them of predators, and aid in synchronized school swimming. Now scientists have developed a lateral line for submaries. Our development of an artificial lateral line is aimed at...

Enormous cave bears that once inhabited Europe were the first of the mega-mammals to die out, going extinct around 13 millennia earlier than was previously thought, according to a new estimate. Why'd they go? In part because they were vegetarians. The new extinction date, 27,800 years ago, coincides with a...

Ancient Sea Predators Shed Skin Secrets
Predatory reptiles called ichthyosaurs cruised the oceans between 230 million and 90 million years ago. In a classic case of convergent evolution, their body and fin shapes resembled those of today's dolphins, tunas, and great white sharks—the fastest swimmers in the sea. A new study shows that the convergence even...
