London, Apr 17 : US researchers are designing a laser-guided microwave blaster to destroy explosives.

The weapon, called the Multimode Directed Energy Armament System, could destroy the electronic fuse of an explosive device or missile, such as a roadside bomb, or immobilise a vehicle by disabling its ignition system, reports New Scientist.

It works by creating a plasma channel that acts as a waveguide for the stream of microwaves, and uses a high-power laser to ionise the air.

The project is the brainchild of the US army''s Armament Research, Development and Engineering Centre (ARDEC).

Washington, Apr 17: Hollywood actor Michael Caine revealed that his forthcoming flick's script managed to do the task that no script has been able to do - it made him cry.

The legendary actor revealed that he was bowled over by the script that reduced him to tears.

Caine, who plays a magician in the flick called `Is Anybody There', revealed that though he had worked in multifarious flicks, he had never shed a single tear on his flick's scripts.

Washington, Apr 17: People who have easy access to stores, transit stops and sidewalks are two times more likely to be physically active than those without these amenities, says a new study.

The study led by San Diego State University has shown that access to sidewalks is the most important factor for physical activity, possibly because people use them for recreation like jogging and in-line skating as well as for transportation.

"Our study had a great deal of variation in neighborhoods," said lead author Dr James Sallis, a professor at the San Diego State University.

Washington, April 17 : Stanford University researchers claim that they have identified a specific group of cells that can be direct targets of deep brain stimulation (DBS), a Parkinson''s treatment.

Lead researcher Karl Deisseroth attributes this advance to a technique to systematically characterize disease circuits in the brain.

The researcher says that the NSF-funded technology, termed optogenetics, enabled them to precisely control individual components of the circuit implicated in Parkinson''s disease.

Washington, April 17: A long-time friend of Hillary Clinton jokingly said during an online radio show that he would have no qualms about the U. S. Secretary of State appearing in a risque promotional advertising campaign to make one million dollars to pay off the bills left over from her unsuccessful presidential bid.
