Homeland Security Builds Robo-Tuna

E! Science News reports that the DHS is building a robot tuna. Just pray that the terrorists don’t get access to weaponized mayonnaise…

The Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T) is funding the development of an unmanned underwater vehicle designed to resemble a tuna, called the BIOSwimmer™. Why the tuna? Because the tuna has a natural body framework ideal for unmanned underwater vehicles (UUVs), solving some of the propulsion and maneuverability problems that plague conventional UUVs.

Inspired by the real tuna, BIOSwimmer™ is a UUV designed for high maneuverability in harsh environments, with a flexible aft section and appropriately placed sets of pectoral and other fins. For those cluttered and hard-to-reach underwater places where inspection is necessary, the tuna-inspired frame is an optimal design. It can inspect the interior voids of ships such as flooded bilges and tanks, and hard to reach external areas such as steerage, propulsion and sea chests.

Fukushima Tuna Sushi Now Being Served?

Bluefin_tunaIn 2008 the New York Times reported that

“laboratory tests found so much mercury in tuna sushi from 20 Manhattan stores and restaurants that at most of them, a regular diet of six pieces a week would exceed the levels considered acceptable by the Environmental Protection Agency.”

If you’re still eating tuna, you can also now start worrying about radiation poisoning, courtesy of the nuclear geniuses from Fukushima, Japan. Report via Reuters:

Low levels of nuclear radiation from the tsunami-damaged Fukushima power plant have turned up in bluefin tuna off the California coast, suggesting that these fish carried radioactive compounds across the Pacific Ocean faster than wind or water can.

Small amounts of cesium-137 and cesium-134 were detected in 15 tuna caught near San Diego in August 2011, about four months after these chemicals were released into the water off Japan’s east coast, scientists reported on Monday.

That is months earlier than wind and water currents brought debris from the plant to waters off Alaska and the U.S.
