New laser technique may be used to detect microbial life forms in Martian iceOctober 2nd, 2009 WASHINGTON - Scientists have said that an innovative new laser technique could be used to detect microbial life forms in Martian ice. According to scientists, the technique, called L.I.F.E.
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.
Storing light pulses can boost quantum computing furtherSeptember 11th, 2009 SYDNEY - A new way of storing and 'echoing' pulses of light allows bursts of laser to work as a flexible optical memory and potentially assist in extending the range of quantum information systems. A team at the ARC Centre of Excellence in Quantum-Atom Optics has demonstrated how photon echoes can be used to create a quantum memory device - meaning that pulses of light can be captured, stored and then released on demand.
Laser cooling may be used to create "exotic" states of matterSeptember 9th, 2009 WASHINGTON - In a new study, scientists have determined that the technique of laser cooling could be used to create "exotic" states of matter. According to a report in National Geographic News, in a new technique, Martin Weitz and Ulrich Vogl of the University of Bonn in Germany used a laser to bring the temperature of dense rubidium gas far below the normal point at which the gas becomes a solid.
New laser technology makes it possible to turn light into soundSeptember 5th, 2009 WASHINGTON - A team of scientists has developed a new laser technology that has made it possible to turn light into sound. Developed by scientists at the Naval Research Laboratory, US, the technology has the potential to expand and improve both Naval and commercial underwater acoustic applications, including undersea communications, navigation and acoustic imaging.
Soon, soundwaves may help find early dental decayAugust 25th, 2009 WASHINGTON - Aussie researchers are developing a tool that can use sound waves to identify early stages of tooth decay by measuring the mineral content of teeth. Tooth decay begins by acid-forming bacteria eating away at the enamel, causing minerals to leach from it, softening, and weakening the tooth.
New technique to detect metabolites from a single drop of bloodJune 19th, 2009 WASHINGTON - A single drop of blood could soon be able to identify various blood related metabolites-such as sugars, fatty acids, amino acids and other organic substances-from plant or animal tissue samples. Scientists at the Max Planck Institute for Chemical Ecology in Jena and their colleagues from the Czech Academy of Sciences in Prague have developed a new method to quickly and reliably detect metabolites from only a drop of blood.
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.
Rare radio supernova in nearby galaxy is nearest supernova in 5 yearsMay 28th, 2009 WASHINGTON - A rare radio supernova found by astronomers last month has been estimated to be the nearest supernova in five years, which underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. The radio supernova was discovered on April 8 in M82, a small irregular galaxy located nearly 12 million light years from Earth in the M81 galaxy group, by the Very Large Array, a New Mexico facility operated by the National Radio Astronomy Observatory (NRAO).
Lasers to "talk" to submarines in futureMay 20th, 2009 WASHINGTON - Navy physicists have announced that lasers, which can create loud bangs under the sea, might someday replace sonar for sending messages to submarines. Conventional sonar mapping uses pulses of sound, which require towed arrays of speakers and receivers.
'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.
New technique enables creation of features 2500 times smaller than width of human hairApril 11th, 2009 WASHINGTON - A team of scientists has developed a technique that enables the creation of features 2500 times smaller than the width of a human hair, which is a significant advancement in the nanofabrication Process. The ability to create tiny patterns is essential to the fabrication of computer chips and many other current and potential applications of nanotechnology.
Technique measures heat transport in the Earth's crustMarch 31st, 2009 WASHINGTON - A scientist has developed a technique that provides much more accurate data on heat transport through rocks in the Earth's crust than conventional methods, which brings scientists closer to a better understanding of the planet's interior. The scientist in question is Anne M.
Laser treatment on rise in USMarch 25th, 2009 WASHINGTON - Over the past three years there has been a drastic increase in the number of patients seeking laser treatments to take light-years off their faces, says a new American survey. According to American Academy of Cosmetic Surgery (AACS)'s annual Procedural Survey, there has been a 456pct increase in the number of males undergoing laser resurfacing, compared to 215pct in females.
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.
