MIT researchers have designed a new robotic underwater vehicle that can hover in place like a helicopter -an invaluable tool for deepwater oil explorers, marine archaeologists, oceanographers and others.
The new craft, called Odyssey IV, is the latest in a series of small, inexpensive artificially intelligent submarines developed over the last two decades by the MIT Sea Grant College Program’s Autonomous Underwater Vehicles Laboratory. The Odyssey series revolutionized underwater research in the 1990s by introducing the thrifty and highly capable underwater robots. But the previous Odyssey vehicles still had one significant limitation: Like sharks, they could only operate while continuously moving forward.
The new Odyssey IV, which has just completed sea trials off Woods Hole, Mass., can move through the deep ocean, up to 6,000 meters down, stopping anywhere in the water column and constantly correcting for currents and obstacles. Navigating to its preprogrammed destination, it can hover in place, making detailed inspections of the footings of an offshore oil platform, or photographing the flora and fauna around an undersea vent.

The scope of connecting neurons living on electrodes has started in 1972, when scientists began to “grow” heart cells in vitro so as to save electric lessignaux. And that since 1979, the U.S. scientists began developing the technology to stimulate and record the signals emitted by neurons cultured in vitro, leading Today the multi electrode array (multi-electrode arrays, or MEA) which, according to Steve Potter, is the key to a better understanding of our brain. “With this kind of device, very simplified version of what happens in the human brain,” you can manipulate neurons much more easily than you can do so on an animal, for example by cutting some connections and see the effects General on signaling … ”
