11-09-20 The brightest gamma ray beam ever created -- more than a thousand billion times more brilliant than the sun -- has been produced in research led at the University of Strathclyde, and could open up new possibilities for medicine. Physicists have disc...

11-09-19 A research team at Michigan State University has developed a laser that could detect roadside bombs -- the deadliest enemy weapon encountered in Iraq and Afghanistan. The laser, which has comparable output to a simple presentation（描述） pointer, p...

11-09-14 Researchers at Vanderbilt University have developed a new technique that uses a single UV laser pulse to zap（攻击，打败） away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical forces at w...

11-02-18 More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discover...

10-12-22 December is a time for twinkling lights, and scientists at the Department of Energy's Thomas Jefferson National Accelerator Facility are delivering. They've just produced a long-sought, rare color of laser light 100 times brighter than that generate...

10-09-27 Portable devices with painless laser beams could soon replace X-rays as a non-invasive way to diagnose disease. 带有无痛激光束的便携设备可能将迅速取代X射线成为诊断疾病得力工具。 Researchers say that the technique could become widely available in abo...

10-09-03 Protecting helicopters in combat from heat-seeking missiles is the goal of new laser technology created at the University of Michigan and Omni Sciences, Inc., which is a U-M spin-off company. Battlefield terrain（地形，地势） in places like Afghanis...

10-03-29 Tiny chemical sensors implanted into patients could help diagnose disease and track its progress, following a development by scientists. Researchers have developed tiny probes comprising gold-coated particles. These can be inserted into cells, enabl...

10-02-22 For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high- resolution（分辨率） imaging. And for the past two decades, Unive...

09-09-09 US military researchers are developing a method for communication that uses lasers to make sound underwater. 美国军方研究人员正在研究一种使用激光在水中发声的通信方法。 The approach could use commercially available lasers The approach focuses laser l...
