invisible (Page 3)

The brave soldiers who went in to take out Osama bin-Laden must have wished they could be invisible. Scientists are determined to figure out how to do this. If we succeed, it would certainly be an effective tool to use in a war–but it would be effective for terrorists too. Researcher Joachim Fischer says that watching things disappear "is an amazing experience." But making items vanish is not the reason he creates tiny invisibility cloaks. This new technology, called "transformation optics" has learned how to manipulate light in ways long thought to be impossible.read more

We have the scan and the pat down to thank for this: Science similar to the type used in airport body scanners could soon be used to detect everything from miniscule defects in aerospace vehicles and concrete bridges to skin cancer. There is more going on than can be seen on the surface! (NOTE: Subscribers can still listen to this show).

Scientists have been experimenting with invisibility for a long time, mostly on the quantum level. But now they’ve learned how to make large objects, which are visible to the naked eye, invisible as well. How do they do it?

Scientists are still trying to create an invisibility cloak. Researchers have found ways to use magnetic resonance to capture rays of visible light and route them around objects, rendering those objects invisible to the human eye.

Electrical engineer Elena Semouchkina is developing a nonmetallic cloak that uses identical glass resonators a special type of glass which does not conduct electricity. This cloak makes objects hit by tiny infrared waves disappear from view.

Earlier attempts by other researchers used metal rings and wires. “Ours is the first to do the cloaking of cylindrical objects with glass,” Semouchkina says.
