Airborne laser to shoot ballistic missile as part of flight testSeptember 12th, 2009 LONDON - Soon, the Airborne Laser (ABL), built into a customized Boeing 747, is ready for flight tests, in which it will try to shoot a ballistic missile. According to a report in New Scientist, the US Department of Defense's Missile Defense Agency (MDA) has developed the ABL.
New laser gun to dazzle Somali piratesSeptember 8th, 2009 LONDON - A British defence manufacturer has designed a laser gun that can be used to dazzle pirates, leaving them incapacitated, thus becoming the perfect weapon to fight Somali pirates. According to a report in the Telegraph, known as the 'Laser Dazzle System, the device is powerful enough to incapacitate pirates up to 1,000 yards away, while leaving them physically unscathed.
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.
'Laser dazzler' to stop careless drivers without blinding themJuly 2nd, 2009 LONDON - Reports indicate that the Pentagon is developing a laser dazzler that will force drivers to stop without harming their eyes. When a vehicle approaches a checkpoint at speed, ignoring warning signs to slow down, troops do not know whether the driver is simply careless or a suicide bomber.
Laser beam powered optical transistor may lead to ultrafast light-based computersJuly 2nd, 2009 LONDON - Swiss researchers have made an optical transistor that uses one laser beam to control another, an instrument that could form the heart of a future generation of ultrafast light-based computers. Conventional computers are based on transistors, which allow one electrode to control the current moving through the device and are combined to form logic gates and processors.
Zap wrinkles and sun spots with new laser toolJune 2nd, 2009 LONDON - When 48 year-old Margaret Miglia looked at herself in the mirror, she couldn't believe her youthful looks, free of all the wrinkles and sunspots, thanks to a new laser tool used by cosmetic surgeons. I had the procedure done two-and-a-half weeks ago and I love it.
New tool studies hair to say what one ate, where one travelledMay 28th, 2009 LONDON - Variation in sulphur concentration in the hair can reveal one's recent diet and the places one has been to. A new laser tool based on this can be very handy to investigators tracking terrorists.
'Laser within a laser' could take out bombs and explosive-laden vehiclesApril 27th, 2009 WASHINGTON - Reports indicate that the US Army is working on developing a laser within a laser that could blow up roadside bombs and explosive-laden vehicles from a distance. A side effect of high-energy lasers is that they heat up and ionize the air molecules they pass through.
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.
Scientists propose active optical clockApril 14th, 2009 WASHINGTON - In a new study, a team of scientists has proposed the concept, principles and techniques of active optical clock. The study was done at the Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University.
Scientists demonstrate laser with controlled polarizationApril 13th, 2009 WASHINGTON - A team of scientists has demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. The demonstration was made by applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS), in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan.
Early land creatures borrowed shells for protection around 500 mln yrs backApril 11th, 2009 LONDON - In a new research, scientists have studied the fossilized tracks left by arthropods 490 to 510 million years to suggest that these creatures crawled out of the ocean onto land and borrowed shells to survive in an otherwise hostile world. According to a report in New Scientist, the research was done by Palaeontologist James Hagadorn of Amherst College in Massachusetts, US.
Laser op can end that stinky sweat from armpit for goodMarch 12th, 2009 LONDON - British surgeons are offering to permanently treat excessive armpit perspiration with the aid of a new 60-minute laser operation. he Laser Sweat Ablation service, launched on Monday, will cost around 3,500 pounds.
Laser man mars Australia's T20 win over South AfricaJanuary 13th, 2009 MELBOURNE - A spectator who flashed a laser torch to distract rookie South African fast bowler Wayne Parnell at the Gabba Tuesday night faces a fine of up to Australian $8,000 and potential jail time of up to three years. Cricket Australia (CA) Wednesday apologised to the South African team management over the laser scandal, which was clearly picked up by TV cameras when a green light flashed across Parnell as he dived at long-off to catch a skied shot from Australian batsman Michael Hussey.
Researchers find ways of making laser more efficientDecember 22nd, 2008 WASHINGTON - A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring, homeland security, medical diagnostics and other areas that require extremely sensitive detection of different chemicals.
