Laser tests may soon replace dentist's dreaded drillAugust 31st, 2009 LONDON - The dentist's dreaded drill may soon be a thing of past, thanks to the laser tests University of Sydney scientists have developed to identify weaknesses in dental enamel. Currently, X-rays and metal probes are used to check cavities, but they fail to detect weaknesses in the enamel in time to repair the surface.
New laser technique may help find supernovasAugust 12th, 2009 WASHINGTON - Researchers at the University of Gothenburg, Sweden, have developed a laser technique that, in combination with standard techniques, would help to find supernovas. To find a supernova, the new technique would have to search for one single atom of a certain isotope of hafnium on Earth, which would prove that a supernova once exploded near our solar system.
Laser technology creates new forms of metal and enhances aircraft performanceJuly 16th, 2009 WASHINGTON - A team of scientists is using laser light technology to create new forms of metal and enhance aircraft performance. The laser light technology is being used by AFOSR (Air Force Office of Scientific Research) funded researchers at the University of Rochester to help the military create new forms of metal that may guide, attract and repel liquids and cool small electronic devices.
World's most powerful laser, to be used for checking old nuclear weapons, unveiled in Calif.May 31st, 2009 World's strongest laser unveiled at California labLIVERMORE, Calif. — The world's most powerful laser, created to help keep tabs on the nation's nuclear weapons stockpile while also studying the heavens, has been unveiled.
Laser doubles brightness of bulb filamentsMay 30th, 2009 WASHINGTON - An ultra-powerful laser not only doubles the brightness of light bulbs filaments but also slashes their power consumption, according to a new study. "We've been experimenting with the way ultra-fast lasers change metals, and we wondered what would happen if we trained the laser on a filament," said Chunlei Guo, associate professor of optics at the University of Rochester, who led the research.
500K Brits still using mobiles while drivingMay 26th, 2009 LONDON - Despite various campaigns, nearly 500,000 motorists are using hand-held mobile phones while driving, a new UK study has found. And the worst culprits are drivers of trucks and vans, the study found.
Soon, microwaves that could defuse bombsApril 17th, 2009 LONDON - US researchers are designing a laser-guided microwave blaster to destroy explosives. The weapon, called the Multimode Directed Energy Armament System, could destroy the electronic fuse of an explosive device or missile, such as a roadside bomb, or immobilise a vehicle by disabling its ignition system, reports New Scientist.
Battlefield laser weapon can destroy rockets, mortars and artillery shellsApril 1st, 2009 LONDON - A US based company has developed a battlefield laser weapon that can fire a strong beam, which can destroy rockets, mortars and artillery shells. "We're doing our part to make gunpowder a 20th-century technology," said Dan Wildt of Northrop Grumman, whose battlefield laser weapon passed another milestone last week.
