Sharks Can Always be Improved

In a world gone mad, it's nice to know that some good, rational science is taking place that is sure to benefit humankind and the entire planet.I refer of course to the Pentagon's program of improving shark's brains so they can be better spies.

Sure, it costs a few million dollars to improve sharks. And yes, there may be a few slackers in New Orleans going hungry and maybe a few grade schools in places like East St. Louis that might have been able to use that money to buy a furnace or fix their broken windows.

But hey, I've always said, Teach a man to fish and he can eat for a day, but teach a shark to spy and a hundred Pentagon bureaucrats can eat caviar for many days.

Besides that, it's important to remember that while all other human endeavors, like artistic expression, need to be curtailed and controlled, technological research needs to be absolutely unlimited and uncontrolled. It's good for us!

Pentagon develops brain implants to turn sharks into military spies http://www.myantiwar.org/view/74448.html

Military scientists in the United States are developing a way of manipulating sharks by remote control to turn them into underwater spies or weapons.

Engineers funded by the Pentagon have created electronic brain implants for fish that they hope will be able to influence the movements of sharks and perhaps even decode what they are sensing.

Although both Cold War superpowers have trained sea mammals such as dolphins and killer whales to carry out quasi-military duties, this is probably the first time the military have seriously considered using fish.

The Pentagon hopes to exploit the ability of sharks to glide quietly through the water, sense delicate electrical gradients and follow chemical trails, according to New Scientist magazine.

"These researchers hope such implants will improve our understanding of how the animals interact with their environment, as well as boosting research into tackling human paralysis," says New Scientist.

But the research also has a military objective. "By remotely guiding sharks' movements, they hope to transform the animals into stealth spies, perhaps capable of following vessels without being spotted," the magazine says.

The neural implants consist of electrodes buried in the fish's brain which can then be triggered by remote control to stimulate specific areas of the animal's central nervous system.

New Scientist says that the project is funded by the US Defence Advanced Research Projects Agency in Arlington, Virginia, which is also involved in a number of other research studies investigating the use of electronic implants to monitor or control the movements or behaviour of animals.

Scientists at Boston University have already developed brain implants that can influence the movements of dogfish - members of the shark family - by "steering" them with a phantom odour.

The electrodes are attached to the region of the dogfish brain associated with scent detection. When the stimulus is to the right side of the olfactory centre the fish turn right, when it is left, the fish swim left.

The stronger the signal, the more sharply it turns.

The shark study is also designed to investigate the possibility of monitoring the brain activity of a shark to decipher different patterns of activity that indicate whether the fish has detected an ocean current, a scent or an electrical field.
