“We can measure that distance of each individual photon traveling inside the snow,” says Hu, a researcher at NASA’s Langley Research Center.Just as an ant wanders around its underground colony, a photon shot from a space laser takes a random route through the snow.

“Cooking is essential for nutrition, flavor, and texture development in many foods, and we wondered if we could develop a method with lasers to precisely control these attributes.” They used a blue diode laser (5-10 watts) as the primary heating source but also experimented with lasers in the near- and mid-infrared for comparison, as well as a conventional toaster oven.

A big group of scientists centered at CERN, the Swiss particle physics lab, was already the best in the world at making antihydrogen, the antimatter version of hydrogen.

However, to actually control such movements, in the early 1990s Herschel Rabitz, a chemist at Princeton University, and his co-workers pointed out that one would need shaped pulses: complex waveforms that might guide molecular behavior along particular paths.

Now it’s once again in the vanguard, announcing Wednesday that it will be the first automaker to use a lidar laser vision system to enable what it calls “fully autonomous highway driving” in its cars, starting in 2022.That news is the result of a deal with Luminar , the eight-year-old lidar company helmed by 25-year-old Austin Russell.

Meanwhile, the enemies in Receiver 2's eerily empty, procedurally generated levels are various kinds of gun-wielding drones.What Receiver 2 does successfully is highlight the danger of the weapons you're wielding.

Protesters donned foil-lined gas masks to hide their identities and dim the glare of police flashlights.Demonstrators have donned body armor and lined their goggles with reflective film to foil police flashlights and mask their identities.

Sign up here !While windshield wipers may do the job for most people, Tesla’s patent application notes that the process of scrubbing away grime and letting the glass dry results in “unproductive time,” and that the chemicals in wiper fluid could damage a camera’s electronics.

Video: The University of Electro-Communications; The University of Michigan When they used a 60 milliwatt laser to "speak" commands to 16 different smart speakers, smartphones, and other voice activated devices, they found that almost all of the smart speakers registered the commands from 164 feet away, the maximum distance they tested.

Strickland’s explanation at the expert level made total sense, but she also explained it to a child—you know, just in case.“A laser is a way to get light to be a single color, going in a single direction, with all the waves peaking at the same time so the intensity can get very high,” Strickland says.

(Musk has said that a Tesla purchased today has all the hardware needs to become a totally self-driving car —once, of course, the company pushes out the right software update.)

Paradoxically—but just as physicists squinting at screens in an adjacent room had expected—the atoms froze solid, forming crystalline ice.“You hear the shot,” said Marius Millot of Lawrence Livermore National Laboratory in California, and “right away you see that something interesting was happening.” Millot co-led the experiment with Federica Coppari, also of Lawrence Livermore.

And mice don’t have anywhere near our behavioral complexity.“It's important to recognize here the mouse doesn't really have depression per se,” says Yale psychiatrist Alex Kwan, who has studied the effects of ketamine on mouse brains.

One goal for such precise sensors is to create high-resolution images of individual proteins and other molecules, says physicist Adrian Bachtold, a colleague of Ricci’s who is not involved in this work.

“We are the first to show a quantum advantage for transmitted information that two parties have to share to perform a useful task,” said Eleni Diamanti , an electrical engineer at Sorbonne University and a co-author of the result along with Iordanis Kerenidis , a computer scientist at Paris Diderot University, and Niraj Kumar .

Researchers at LakeDiamond, a spinoff of the Swiss Federal Institute of Technology, think their solution could be the dilithium crystal of roaming drones.They have developed an artificial diamond that can help a laser beam maintain its quality over much longer ranges, and say ground-based networks of these diamond-enhanced power sources could send drones flying great distances, without wasting power to haul their big batteries around.LEARN MOREThe WIRED Guide to DronesLakeDiamond CEO Pascal Gallo says the company’s lab-created diamond—a smooth, tiny rectangle placed directly in front of the laser source—can convert a low-power laser diode into a beam with consistent, parallel rays that can stretch several hundred meters.

As a parent in an era where half of my news feed cautions of the perils of living in an overly sanitized world and the other half highlights the dangers of flesh-eating bacteria, just how much exposure to soil are we supposed to give our children?

Once it settles into orbit 310 miles above the Earth, the satellite will start collecting data using a specially designed laser device that will give scientists more data about exactly where ice is melting and how fast.The NASA satellite will scan the Earth’s surface using six green laser beams to measure glaciers and floating sea ice.

The ICESat-2 mission will measure the changing height of Earth's glaciers, ice sheets and sea ice, one laser pulse at a time, 10,000 laser pulses per second. Media accreditation is open for the launch of NASA’s Ice, Cloud and land Elevation Satellite-2, or ICESat-2, scheduled for Saturday, Sept.

Hundreds of people at NASA's Goddard Space Flight Center in Greenbelt, Maryland, worked to build this smart-car-sized instrument to exacting requirements so that scientists can measure minute changes in our planet’s ice.
