There was a time not so very long ago when people who wanted satellite TV or radio required dishes several feet across. Those have since been replaced by today’s compact dishes, but now it looks like even those might be on the road to obsolescence. A recent PhD graduate from The Netherlands’ University of Twente

A transmission capacity of 1.6 terabits per second As rapidly increasing demand for bandwidth strains the Internet’s capacity, a team of engineers has devised a new fiber optic technology that promises to increase bandwidth dramatically. The new technology could enable Internet providers to offer much greater connectivity – from decreased network congestion to on-demand video

All for free   After re-purposing CAPTCHA so each human-typed response helps digitize books, Luis von Ahn wondered how else to use small contributions by many on the Internet for greater good. At TEDxCMU, he shares how his ambitious new project, Duolingo, will help millions learn a new language while translating the Web quickly and

“Now that,” I said, “would be the real Arab Spring.” A FEW weeks ago, I was in Amman, Jordan, talking with educators, when I met a young American woman with the most remarkable job description. Her name was Shaylyn Romney Garrett. She introduced herself by saying that she and her husband, James, were former Peace

The new method can be used to grow biological tissue or to create micro sensors. There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer  precision? Scientists at the Vienna University of Technology developed a method to attach molecules

“By tuning the sound waves, we can create any pattern we want on the surface of a microchip,” In a breakthrough discovery, researchers at RMIT University in Melbourne, Australia, have harnessed the power of sound waves to enable precision micro- and nano-manufacturing. The researchers have demonstrated how high-frequency sound waves can be used to precisely

A nasal brush test can rapidly and accurately diagnose Creutzfeldt-Jakob disease (CJD), an incurable and ultimately fatal neurodegenerative disorder, according to a study by National Institutes of Health scientists and their Italian colleagues. Up to now, a definitive CJD diagnosis requires testing brain tissue obtained after death or by biopsy in living patients. The study

Scientists at the NRL Materials Science and Technology Division are providing solid evidence that there is a new route towards developing novel, lightweight energy storage devices. By moving away from centuries of caustic, hazardous aqueous-based battery cells and instead using non-volatile, thermally-stable ionic liquids, scientists predict multiple new types of batteries. Rather than depend on
