Despite manufacturers have tirelessly designed new types of razor blades for a cleaner shave, the process has stayed virtually unchanged for thousands of years. The difference between a modern razor blade and an ancient roman shaving knife isn't that large, on a fundamental level at least. This may set to change if the Skarp Laser Razor makes its way into the shaving kit market. The gadget is basically a high-tech razor - named so only by function - that uses a highly focused laser beam instead of a blade.
A 30KW high-power laser was demonstrated by Lockheed Martin after it was used to disable a vehicle more than a mile away. One of the great perks of laser weapons is their phenomenal accuracy. To showcase this, the weapon was directed specifically on the hood of the vehicle, where it fried the engine. The beam from the Advanced Test High Energy Asset, or ATHENA, is believed to be most powerful ever documented in a laser weapon.
Japan just powered up the world's most powerful laser, a monster that shines a 2-petawatt pulse of light. The pulse lasted only one picosecond, or a trillionth of a second, but during this brief time frame the laser definitely concentrated a phenomenal amount of power.
Astronauts onboard the ISS may soon get a new "toy" - a space laser cannon to blast off space debris that might threaten the space station. Even a tiny scratch or dent could cause massive problems, and with us putting more and more stuff in space, the risk of damage constantly increases too.
Princeton researchers demonstrated a novel type of microwave laser - called a maser - so small that's the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.
Shells and bullets have evolved significantly in the past couple hundred years since they were first used, but in principle they’ve remained the same – discharge an explosive to propel a projectile. The 21st century might finally make way to a new class of widespread weaponry based on lasers. These are powerful, much more accurate than […]
The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can’t see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye. Apparently, this isn’t entirely true. In some special conditions, the […]
High speed photography is no longer a new thing… but then again, it depends what you mean by high speed photography; you likely don’t mean one hundred billion frames per second (100,000,000,000 fps) – but that’s exactly what Liang Gao, Assistant Professor at Stony Brook University means. He and his team have developed the world’s fastest […]
For the first time, researchers at the University of Basel used an ultracool atomic gas to cool a very thin membrane to less than one degree Kelvin. The new technique might enable novel investigations of quantum mechanics phenomena and precision measuring devices. Coldest matter in the world lends its freeze In the ultracold world, produced […]

An international team of physicists have used one of the world’s most powerful lasers to create an unusual kind of plasma made out of hollow atoms, by using a breakthrough technique which involved emptying atoms of electrons from the inside out, instead of working from the outer shells inwards. This bizarre physics experiment shows once again […]
Trekkies have a reason to rejoice one again after Japanese researchers have successfully devised the first working phaser – a laser that shoots sound particles instead of light. It will take a while though until you’ll be able to zap your neighbors around with a sound canon, as the scientists still need to work around […]
Physicists at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory, once home to the longest particle accelerator for nearly fifty years, have used the world’s most powerful X-ray laser to distinguish at an atomic level the mechanisms of reaction of a catalyst in action. This unprecedented view will help scientists develop cleaner and […]
We’re all familiar with laser weapons from SciFi movies and novels, but how far away is laser warfare from reality? Very close, if we’re to judge from the recently publicized test run of Rheinmetall Defense‘s 50kW high power laser that can melt through thick armor a kilometer away and shoot tiny mobile targets at twice the distance. […]
A novel technique for cooling antimatter down to the point where it might become almost stationary might provide scientists with a better basis for studying one of the greatest modern mysteries today. Antimatter, as it name implies, is the total opposite of matter and when the two meet they cancel each other out. For instance […]

Called the Linac Coherent Light Source at Stanford, the X-ray […]
Most digital devices today, like displays or blue-ray disks, use lasers which emit the colors red, green and blue, which when combined can render any color in the visible spectrum of light. However, current technology requires a separate laser for each color, since they produce monochromatic light. A team of researchers at Brown University has […]
Researchers at SLAC National Accelerator Laboratory have used the world’s most powerful X-ray laser fired upon a neon gas capsule and thus emit an avalanche of short wavelength X-rays,creating the first atom laser. The same laser was used to heat a lump of matter at over 2 million degrees Fahrenheit – hotter than the sun’s […]
By harnessing the science of both quantum and nano physics, scientists at the Niels Bohr Institute have come up with an innovative new way of cooling semiconductor membranes by using laser light. Through this new technique, the researchers were able to cool the tiny, thin membrane from room temperature to -269 degrees Celsius. Paradoxically, the […]
Anyone scarcely into Iron Man will tell you they wouldn’t want anything more for Christmas than a bone melting ray gun weapon bursting out of your palm. Well, that a fission core artificial heart, but that’s stretching it a bit too far with Santa. Patrick Priebe, a German lab technician, and firstly an Iron Man […]
Junk is not only limited to our planet, we have a problem with space pollution as well.
