Sponges, Skyscrapers, And Low-K

A sponge is a porous structure. So is a skyscraper. These two very different images exemplify the materials being considered for advanced low dielectric constant (κ) materials. Most porous dielectrics that have been tested up to this point resemble sponges. As Intel’s David Michalak explained at this month's Materials Research Society (MRS) Spring Meeting, these materials consist of a ba... » read more

Portable laser weapons For years, the U.S. military has been developing high-energy laser (HEL) weapons. But the massive size, weight and power requirements of laser systems limit their use on many military platforms. The Defense Advanced Research Projects Agency (DARPA) has made a breakthrough in its so-called Excalibur program. The program will develop laser weapons that are 10 times ligh... » read more

Polite cupcake helping robots Cornell and Carnegie Mellon have made a new discovery about robots. If they sound less snippy when they communicate, listeners will respond better. In fact, developers of robots should develop systems that use less confrontational language. In the study, entitled “How a Robot Should Give Advice,” researchers discovered that robots and humans are more lik... » read more
