Preparing for a newborn baby is a lot of work, from buying the bassinet to arranging the diapers. And soldering apart the Wiimote, installing the crib lasers and turning on the camera.
A new Hungarian dad, concerned about monitoring his baby’s breathing, did what any modder would do: He built a baby-breathing-tracker. His name is Gjoci and here are his plans.
A new maser that can work at room temperature and without any powerful magnets could usher in a new age of masing instead of lasing. It may be good timing, as the next generation of lasers could be the most powerful lasers to ever lase. Now this new device could be the simplest maser to ever mase.
Laser light can not only trigger lightning but redirect it, causing it to strike in the same place over and over, according to new research. This means lasers could serve as lightning rods. Because that would be awesome.
In two separate studies, the world’s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter. The atomic laser could be used to watch biological molecules at work, while the creation of hot dense matter could be used to understand the processes of nuclear fusion.
A new long-range laser weapon takes a page from Greek antiquity to thwart marauding pirates at sea. It won’t set their ships on fire, but it can let pirates know they have been spotted and might make them wish for an eye patch, as New Scientist reports.
Lasers can be powerful weapons — they can take down an aircraft at long ranges and in unstable conditions, for instance. But they are hampered by power and size limits, so they’re not widely used by the military (yet).
Lockheed Martin has a solution: a fiber laser that basically works like a backward prism.
An unmanned aerial surveillance drone is only as good as its power source, and as such many technologies are being considered that could drastically extend the duration of drone missions – for instance, DARPA's Vulture program has helped develop a giant solar plane that, theoretically, could fly for five years straight. But Seattle-based LaserMotive thinks laser power is the answer, and to prove it they recently kept a tiny 22-gram helicopter aloft for hours by beaming power to it via a laser.
U.S. Army Special Forces soldiers will deploy with the XM-25 weapon this summer, so that they can shower enemies hidden inside buildings with lethal smart rounds. Veterans of the Afghanistan conflict who tried the weapon predicted it would be a "game changing" gun capable of taking out insurgents hidden behind cover, Military.com reports.
The XM-25 resembles a highly sophisticated grenade launcher that fires laser-guided smart rounds. The laser gauges a distance to target and allows the warfighter to set where the round will detonate, adding or subtracting increments of 3 meters from the laser-spotted point. Then the scope tells a microchip inside the round how far it should travel before exploding.
For decades, electronic devices have been shrinking, in accordance with Moore's Law. Now, as circuits reach the size of single atoms, progress begins to bump up against the physical limitations of matter. Enter the spaser. This new kind of laser produces a beam so small that it could someday form the foundation of circuits made of light, not electrical impulses.
Giant particle accelerators like the Large Hadron Collider (LHC) have become the poster children for big science. Immense in size, cost, and ambition, these gargantuan structures hurl particles at velocities close to the speed of light, in the hopes of uncovering the most basic constituents of matter and energy.
But when Wim Leemans gets his way, particle accelerators will be just another piece of lab equipment, no more obtrusive than a gene sequencer or a desktop printer.
