Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Up until now, studies on electronic and optical devices with materials that are the foundations of modern electronics—such as radio, TV, and computers—have generally relied on nonlinear optical effects, producing devices whose bandwidth has been limited to the gigahertz (GHz) frequency region. Thanks to research performed at the University of Pittsburgh, a physical basis for terahertz bandwidth (THz)—the portion of the electromagnetic spectrum between infrared and microwave light—has now been demonstrated.

Illuminate a piece of metal, such as copper or silver, and the electrons get excited .

With a lot of help from Flipper, scientists have a better shot at understanding phenomena like black holes and supernovae.

Controversy has arisen again about whether holding a cell phone next to the head for too many minutes a day threatens the brain with electromagnetic radiation. The preponderance of evidence continues to indicate there is no threat. Many people do not realize, however, that we are increasingly surrounded by technologies that emit radiation in the same radiofrequency portion of the electromagnetic spectrum: WiFi routers, Bluetooth transmitters and more .

How would you feel if parts of your home, your car, or the airliner you were flying in had blood flowing in artificial veins and arteries? Nicely chilled is the answer

New experiments find that cell phone signals don't just confuse bees, they off them.
