Physicists in France may be leading the way to a new generation of IT wizardry after revealing on Sunday they had used ultra-fast lasers that could accelerate storage and retrieval of data on hard discs by up to 100,000 times, AFP reported. The latest achievement expands on Nobel physics prize winning research by Albert Fert of France and Peter Gruenberg of Germany, who ushered in a revolution in miniaturized storage in the 1990s. The duo won a Nobel in 2007 after they discovered that tiny...

Laser Process Doubles Brightness for the Same Amount of Energy An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can. The laser process creates a unique array of nano- and micro-scale structures on the surface of...

Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. "You can remove a cell with high precision in 3-D without damaging the cells above and below it," Ben-Yakar says. "And you can see, with the same precision, what you are doing to guide your microsurgery."...

Using a laser, scientists have turned aluminum into gold, or at least made it look like gold. They can also make it blue, gray or almost any color in the rainbow. Chunlei Guo of the University of Rochester and his colleagues blasted extremely brief and intense laser bursts at small pieces of metal to change their surface properties. The laser blasts form nanoscale and microscale structures in the surface that reflect a certain color of light, making the metal appear a different color...

A team of scientists and engineers at The University of Alabama in Huntsville (UAH) are conducting research that could one day save humanity from asteroids threatening Earth. UAH Laser Science and Engineering Group (LSEG), headed by Dr. Richard Fork, professor of Electrical and Computer Engineering, is conducting research into characterizing and deflecting asteroids that may endanger Earth. It sounds like science fiction, but Fork, who has a doctorate from Massachusetts Institute of...
