There's a challenge in bringing deep-sea fish up to the surface. Unless divers poke a hole in the animal's swim bladder, that organ could rupture due to the gas within it expanding as the water pressure lowers upon ascent. A new device, however, is designed to make such poking unnecessary.

There are an ever-increasing number of wireless mobile devices transmitting and receiving data, even though there's only a limited amount of bandwidth available to them. In order to keep their signals from jamming one another, scientists have replicated a system used by a cave fish.

Humans have pretty much traipsed over all the dry parts of the planet, but the vast oceans still hide plenty of secrets from us landlubbers. Now, an ongoing study has identified a new species, the Mariana snailfish, which appears to be the deepest-dwelling fish in the world.

We’re still a long way from having robots blend seamlessly into our society. But apparently fish are easier to fool, since a team from EPFL has successfully integrated a robotic impostor into schools of zebrafish, to the point where the robot could guide the group’s behavior.
