Many of the same genes that lampreys have that allow for natural repair of injured spinal cords are also active in the repair of the peripheral nervous system in mammals, including humans, according to a new study. The findings are consistent with the possibility that in the long term, the same or similar genes may… Read more

When you’re as soft and delicious as a cuttlefish, evading predators is a full-time job. Not only do these squid-like creatures employ stealthy visual camouflage when a predator looms nearby, new research shows they also manage to cloak their electrical fields. One of the cuttlefish’s major predators, the shark, has eyes on the side of… Read more

A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of carbon dioxide absorbed by the ocean. The meaning of these findings remains to be seen—as does whether the rapid growth in the tiny floating phytoplankton’s population is good or bad… Read more

Scientists have sequenced the genomes of two marine worms and their findings clarify the 570-million-year evolution that transformed gills into the pharynx that allows people to bite, chew, swallow, and speak. The draft genome sequences of two species of acorn worm, which live in U-shaped burrows in shallow, brackish water, are the first genomes of… Read more

Scientists have solved a longstanding mystery about how some fish can seem to disappear from predators. The discovery could help materials scientists and military technologists create more effective methods of ocean camouflage. The fish use microscopic structures called platelets in their skin cells to reflect polarized light. This kind of light is made up of… Read more
