    The Z-Ro Retinal Obfuscation weapon mounted to a handgun. Last summer’s riots in Ferguson, Missouri, prompted much talk by President Obama and certain members of Congress about the need to demilitarize local police forces. Nearly a year later, the opposite is happening. New and more powerful weapons are flowing into local police departments daily, and still others are new to the marketplace. One weapon about to make its debut is the “Z-Ro Retinal Obfuscation” gun. When fired, the gun allows an officer to temporarily blind his targeted subject for up to 15 minutes. The new “compliance weapon” made a...

    Lockheed Martin turned up the heat on its laser weapon technology and destroyed a truck from one mile away. The Maryland-based company’s test of the ATHENA laser weapon was the highest power ever recorded of a laser weapon of its type. The Advanced Test High Energy Asset’s March 3 test destroyed its target in a “matter of seconds,” the company said in a statement. An image of the smoking vehicle accompanied its announcement. “This test represents the next step to providing lightweight and rugged laser weapon systems for military aircraft, helicopters, ships and trucks,” said Keoki Jackson, chief technology officer...

    Lasers have staggering range, can attack land or air-based targets and are dirt-cheap to fire, making them ideal for a military with one eye on the budget. Now, Lockheed Martin has worked out that the technology could also be used for stopping a car without resorting to lethal force. The company has been testing out a new fiber-optic laser, called ATHENA, which was able to burn through the engine manifold of a truck that was over a mile away. For the purposes of the test, the truck had its engine and drive train running, although the vehicle itself was...

    A US military satellite exploded after detecting an unexplained “sudden spike in temperature”, sending dozens of chunks of debris tumbling into different orbits around Earth. ===== Air Force Space Command confirmed to SpaceNews.com that the “catastrophic event” came after “a sudden spike in temperature” was detected, followed by “an unrecoverable loss of attitude control”. While operators were deciding how to “render the vehicle safe” they detected a debris cloud which indicated that the satellite had been destroyed.

    Hobbyist Patrick Priebe has created a terrifyingly awesome laser watch that will burn through objects from afar The Apple Watch is already obsolete and it isn't even in the shops yet. The reason is simple – it doesn't contain a laser that can actually burn stuff. If that's what you're looking for in a smartwatch, forget about Apple and look towards the work of hobbyist Patrick Priebe. He's knocked together what he describes as the "Bond-inspired laser watch" and it might well consign the Apple Watch to the bin of history. That's because this isn't just some laser pointer that...

    The agony of root canal surgery and the need for tooth fillings could soon be ended after scientists discovered a way to make a rotting tooth repair itself using a laser beam. Just five minutes under a laser was enough to kickstart the healing process inside the mouth, the researchers found. The new technique—although only tested on rats so far—could prevent the need for fillings for some types of decay, and may eventually replace painful and expensive root canal treatment. Researchers, which included experts from the US government’s dental research team, found a blast of intense light from a laser...

    Optical scientists at the University of Arizona and University of Central Florida have developed a new type of laser technology capable of sending high-intensity beams through the atmosphere much farther than what was previously possible. The research, which was recently published in the journal Nature Photonics, is still in the laboratory phase. However, with further development, this technology could be used to divert lightning bolts away from buildings in the future. Here’s how that works. When the laser is fired, the high intensity beam leaves a channel of plasma (ionized molecules stripped of their electrons) in its wake. This column...

    The recovery of objects obscured by scattering is an important goal in imaging and has been approached by exploiting, for example, coherence properties, ballistic photons or penetrating wavelengths. Common methods use scattered light transmitted through an occluding material, although these fail if the occluder is opaque. Light is scattered not only by transmission through objects, but also by multiple reflection from diffuse surfaces in a scene. This reflected light contains information about the scene that becomes mixed by the diffuse reflections before reaching the image sensor. This mixing is difficult to decode using traditional cameras. Here we report the combination...

    A laser powerful enough to tear apart the fabric of space could be built in Britain as part major new scientific project that aims to answer some of the most fundamental questions about our universe. Due to follow in the footsteps of the Large Hadron Collider, the latest "big science" experiment being proposed by physicists will see the world's most powerful laser being constructed. Capable of producing a beam of light so intense that it would be equivalent to the power received by the Earth from the sun focused onto a speck smaller than a tip of a pin, scientists...

    Scientists have long sought easier ways to make the costly material known as enriched uranium — the fuel of nuclear reactors and bombs, now produced only in giant industrial plants. One idea, a half-century old, has been to do it with nothing more substantial than lasers and their rays of concentrated light. This futuristic approach has always proved too expensive and difficult for anything but laboratory experimentation. Until now. In a little-known effort, General Electric has successfully tested laser enrichment for two years and is seeking federal permission to build a $1 billion plant that would make reactor fuel by...

    Superman's memory crystals may become reality in computers Computers may soon be saving their data onto hard drives made of glass following research by British scientists who have developed a way of storing information similar to the "memory crystals" seen in the Superman films. By Richard Gray, Science Correspondent 9:45AM BST 14 Aug 2011 Researchers at Southampton University used lasers to rearrange the atoms in pieces of glass, turning it into new type of computer memory. They claim the glass memory is far more stable and resilient than current types of hard-drive memory, which have a limited lifespan of a...

    TeraDiode, a spinout company from MIT and located nearby in Littleton, MA, has unveiled, a new powerful direct-diode laser capable of cutting all the way through steel up to half an inch thick at various speeds. The laser is based on technology developed by company co-founders Dr. Bien Chann and Dr. Robin Huang while still at MIT. The new laser system is based on semiconductor technology, which means it uses electricity, rather than chemicals, and employs an optical system that directs multiple individual beams into one single stronger one, and, according to the company website, the laser has "revolutionary TeraDrive...

    June 20, 2011 (LifeSiteNews.com) – U.S. scientists reported last week they have been able to develop potentially “self-healing” lasers that could be used in the human body for treating diseases such as cancer.  The lasers, however, use human embryonic cells in a controversial experiment that has not yet been approved by the FDA. The experiment findings were published this month in the Nature Photonics journal, by physicists Malte C. Gather and Soek Hyun Yun of the Wellman Center for Photomedicine at the Massachusetts General Hospital.  “This is the first time that we have used biological materials to build a laser...

    Living lasers might transmit information about health and disease. They are also just plain cool. A laser based on living cells has been created by researchers at Harvard Medical School and the Massachusetts General Hospital in Boston. They were motivated to overcome one of the fundamental limitations on biological imaging: it's very difficult to get visible and infrared light in and out of the body. Living lasers have a few basic parts that are drawn from the same list as any laser. First, the researchers genetically modified human liver cells so that they produce large amounts of green fluorescent proteins...
