Not too long ago, Amanda Ghassaei from Instructables caught our attention when she constructed several playable records with a 3D printer. By sending raw audio data through a custom script, she was able to automatically generate 3D designs for a printer to follow – albeit with crude results. Recently, Ghassaei programmed a new code that let her substitute the 3D printer for a laser cutter to carve functional records from wood and other materials.  Read More

Lockheed Martin's ADAM laser system destroys a rocket mid-flight

Lockheed Martin has released a video of ADAM, its high energy laser (HEL) system, taking out a rocket from a range of 1.5 km (0.9 miles). Slowed down, the 300-fps video clearly shows the laser beam striking and tracking a point towards the front of the rocket, before destroying it mid-flight.  Read More

A material known as a plasmonic polypeptide nanocomposite has been shown to strengthen las...

Stitches and staples may be on their way to becoming a thing of the past, thanks to a developing technology known as laser tissue welding. Now, a new gold-based solder has been created, that could make tissue welds in regions such as the intestines much stronger and more reliable.  Read More

With the nasty tendency of its airborne fibers to cause lung cancer, the installation of asbestos building insulation has been banned in many countries for some time now. A lot of buildings still have the insulation, however, the fibers of which can get stirred up when work such as renovations or demolition are being performed. In order to help protect the people performing such work, scientists at the University of Hertfordshire have developed what they say is the world’s first portable, real-time detector of airborne asbestos.  Read More

Cars and lasers, together again (Photo: pop culture geek)

Researchers at the Fraunhofer Institute for Physical Measurement Techniques have come up with a car-mounted laser scanner the size of a shoe box, that can survey the contours of road surfaces at speeds of up to 100 km/h (62 mph). The system detects potholes and other road damage in need of repair. According to the Institute, the Pavement Profile Scanner (or PPS) has surveyed 15,000 km of road since mid-2012, in which time it has proven cheaper, faster and more accurate than existing systems which require hefty attachments to the carrier vehicle.  Read More

3D images taken in daylight from 910 meters away using the new imaging system (Photo: Opti...

Physicists at Scotland’s Heriot-Watt University have created a 3D imaging camera system capable of resolving depth on a millimeter scale at distances of up to one kilometer. Working much like a laser version of radar, the “Time-of-Flight” (ToF) measurement system “pings” a low-powered infrared laser beam off distant objects and records a pixel-by-pixel map using a detector that counts and positions individual photons as they arrive back at the source.  Read More

Laser Weapon System (LaWS) temporarily installed aboard the guided-missile destroyer USS D...

The U.S. Navy took a step farther away from John Paul Jones and closer to James T. Kirk as it announced that a solid-state laser weapon will be deployed on a U.S. Navy ship in fiscal year 2014. The announcement that the Laser Weapon System (LaWS) will deployed on board USS Ponce (AFSB[I] 15) two years ahead of schedule was made on Monday at the Sea-Air-Space exposition, National Harbor, Maryland. The deployment is the latest in a line of recent recent high-energy laser demonstrations carried out by the Office of Naval Research (ONR) and Naval Sea Systems Command.  Read More

Scientists have been able to instantly cure rats of cocaine addiction, by applying laser l...

Like so many other illicit drugs, cocaine can be extremely, destructively addictive. Recent research suggests, however, that ridding people of such addictions may be as simple as zapping them on them scalp. In a study conducted at the National Institutes of Health (NIH), and at the Ernest Gallo Clinic and Research Center at UC San Francisco, scientists were able to turn cocaine addiction on and off in rats via pulses of laser light to their brains.  Read More

Is a sun-powered space laser the answer to stopping major asteroid impacts? (Photo: Shutte...

This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14 passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the Russian city of Chelyabinsk, damaging hundreds of buildings and injuring thousands. Scientists have been quick to point out that both of these events – a meteor exploding over a populated area and a large asteroid passing through Earth's geosynchronous orbit – are quite rare, but when the worst case scenario is the complete annihilation of all life on Earth, it's probably best to be prepared. That's why researchers in California recently proposed DE-STAR – a system which could potentially harness the sun's energy to dissolve wayward space rocks up to ten times larger than 2012 DA14 with a vaporizing laser.  Read More

A research team at Singapore’s Nanyang Technological University (NTU) has successfully used a laser to cool down a semiconductor material known as Cadmium Sulfide. The results of the recently published study could lead to the development of self-cooling computer chips and smaller, more energy efficient air conditioners and refrigerators that don't produce greenhouse gases.  Read More
