    DJI has announced that it's partnering with FLIR to create a thermal imaging camera for its Inspire 1 and Matrice 100 drones. The Zenmuse XT camera should be a boon for tasks like spotting fires, search and rescue and measuring the thermal efficiency of homes. The drone company is already by far the most popular for cinematographers and hobbyists, but DJI has lately been targeting industrial operations, having recently launched a pesticide-spraying model. The infrared camera could also help farmers monitor crop growth, and would be useful for folks like police, firefighters and building inspectors.

    Quantum entanglement, where two particles are inextricably linked, is a real thing. However, creating that odd behavior has been extremely difficult so far -- you have to cool things down to near absolute zero to pull it off on a significant scale. Or rather, you did. Researchers have successfully produced macro-scale quantum entanglement at room temperature through the one-two combo of an infrared laser (which aligned magnetic states) and electromagnetic pulses (for the actual entanglement). The experiment only included enough electrons and nuclei to fill the space of a blood cell, but that still amounts to linking "thousands" of particles.

    Until scientists perfect bionic vision, shouldn't there be a better way for the blind to get around than a simple cane? That's the idea behind Sentiri, a proximity-sensing headband that helps steer users around by motor-driven haptic feedback. It detects objects in the environment using infrared depth sensors, then varies the level of vibrations to the user's head to help them avoid obstacles. If it's connected to a smartphone with an app like Google Maps, the tool can also safely guide you from point 'A' to point 'B.' The company behind it, Chaotic Moon, also created a "haptic language" that transmits extra information to users by changing the frequency, intensity and number of vibrations.

    A group of scientists at the University of Washington were able to successfully refrigerate water using an infrared laser. This is a big deal because researchers weren't even sure this was possible as water tends to heat up when illuminated. However, by using an infrared laser and nanocrystal, it surprisingly created the opposite effect, which is a world first. The team of scientists were able to cool liquid water by 36 degrees Fahrenheit (20 degrees Celsius). The crystal absorbed the light's photons and then when the photons were released, they had a higher energy value compared to when they first entered. These photons then scattered and carried away heat, cooling the surrounding water.

    Thermal imaging devices like night-vision goggles can help police, search-and-rescue teams and soldiers to pick out bad guys or victims through walls or in complete darkness. However, the best devices require cryogenic cooling, making them heavy, expensive and slow. Enter graphene, the semi-conducting material that's 100 times stronger than steel -- researchers from MIT have built a chip out of the material that may solve the problem. The resulting infrared sensors were small enough that they could be "integrated in every cellphone and every laptop," according to the study's co-author, Tomas Palacios.

    Researchers from China have taken shape-memory materials to a creepy new level with a self-folding paper that can propel itself by "walking." Sorcery? Not quite. It's actually made from everybody's favorite wonder-material, graphene, and heated by an infrared laser that causes active regions to contract, then expand when it shuts off. By placing the regions in strategic locations, the team can make the paper move in any direction. It isn't going to put a scare into Sarah Connor just yet, but the team thinks it could one day be used to create contracting "muscles" that do power murderous 'bots. In the near term, the material could lead to low-cost temperature and humidity sensors.

    Egyptologists, rejoice. A new project was launched on the weekend with the goal of scanning Egypt's pyramids to find secrets about how they were built, and even discover hidden rooms and chambers. The project is headed by Egypt's antiquity ministry, which is heading a team of experts from Japan, France and Canada. The aim is to use infrared scanners and rare, esoteric cosmic ray detectors to map the interior of several pyramids, including the Pyramids of Cheops and Chephren at Giza. The team said it may also use the same technique to prove (or disprove) a theory that the legendary Queen Nefertiti is buried in a chamber next to Tutankhamun.

    Scientists might soon have a much easier time discovering every last nuance of other planets. Researchers have developed a quantum cascade laser (which sounds like an amazing sci-fi weapon, by the way) that can cover a very wide range of infrared wavelengths at the same time, making short work of detecting many chemicals. Astronomers, including study backer NASA, could use it to determine the contents of a planet's surface without touching it -- important when you'd rather not risk breaking samples, or when it's not possible to touch down on the surface in the first place.

    You probably aren't a fan of showing up at the coffee shop right when there's a large line, or at the gym when there are no free machines. Wouldn't it be nice if you could find out how busy a place is at any given moment, without resorting to estimates? The new Density sensor might help. The tiny infrared detector is effectively a smarter, more connected pedestrian traffic sensor: it tells apps how many people are entering or leaving a building at any moment, giving you a good sense of whether that restaurant is packed or blissfully empty. Shops can use that data to their advantage, too. They can offer discounts whenever it gets quiet, or notify you the moment there's a free seat.

  • Researchers boost solar energy by tapping infrared light

    Our sun blasts out over 50 percent of its energy as "near-infrared" light, but solar cells only harvest visible light. As a result, the best commercial panels only convert about 20 percent of solar energy to electricity. Researchers from UC Riverside have now figured out how to "upconvert" infrared energy into much more useful visible light, a process that could make solar panels up to 30 percent more efficient. To do it, the team combined semiconductors with organic molecules, resulting in a material that essentially helped them "reshape the solar spectrum," according to lead researcher Christopher Bardeen.

  • Army scientists build smaller, tougher, cheaper solar cells

    Army researchers at the Redstone Arsenal have announced a significant breakthrough in solar energy production. They've created a photovoltaic solar panel that is smaller, more robust and less expensive to build and operate than any other panel currently available. Virtually every solar panel currently in existence relies on a pure silicon construction, however the band gap (the wavelength of light that it can actually be absorbed and converted into electricity) of single crystal silicon is exceedingly narrow compared to the full spectrum shining down from the Sun. Not only does this mean that conventional panels are missing out on potential power, the ultraviolet and infrared wavelengths actively damage the panels by causing them to heat, warp and crack.

    Those giant, green Hulk hands in your closet might be cool but their utility doesn't extend much beyond freaking out your cat and making tired "you wouldn't like me when I'm angry" jokes. Disney has an idea to remedy that with internet-connected versions of those as well as a pair of Iron Man gauntlets. Wait, smart toys? Yep. As The Wall Street Journal tells it, these Playmation devices will work in concert, via radio frequency and infrared signals, with special action figures as well as other branded apparatus you strap on to your body. Based on what TechCrunch says, these sound an awful lot like a home laser-tag set. Different playthings offer different augmentations (action figures come with new, narrated, playable stories, and you can buy more of the latter via a connected app) but they won't all work together.

    After the Internet was awash with reports that tattoos can negatively affect the Apple Watch's heart rate sensor, Apple has confirmed the issue on its website. In a page dedicated to explaining how the Watch captures your vitals, the company notes: "Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance," adding that "the ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings."

  • Sharp's night vision camera records color even in total darkness

    Say goodbye to the days of monochrome night vision footage, folks. Sharp recently unveiled an infrared security camera that captures color 720p video, even in absolute darkness. The trick is an imaging sensor that uses near-infrared for illumination; unlike virtually every other competitor, this camera doesn't have to resort to conventional lights (and thus give itself away) to get a vivid picture. It's based on tech we've seen before, developed by Japan's National Institute of Advanced Industrial Science and Technology (check out some video from a 2011 demo embedded after the break.) The device will likely be limited to corporate and government customers when it goes on sale in late November, but it could have a big impact on your safety. Building managers will soon have an easier time identifying intruders, not just spotting them -- while the technology might not stop a break-in, it should increase the chances of catching thieves before they strike again.

  • The Big Picture: Infrared satellite images reveal the true extent of a forest fire

    DigitalGlobe's recently launched high-res imaging satellite isn't just in orbit for the sake of creating pretty pictures; it can also uncover things that you might never see at all. As proof, the company has posted before-and-after imagery of a California forest fire that shows off the advantages of WorldView-3's shortwave infrared sensor, which can easily see past clouds and smoke. Suffice it to say that the sensor's effect is dramatic -- areas that would have been completely obscured are suddenly in plain sight, revealing both the perimeter of the blaze and its intensity. The hope is that firefighters will use overhead shots like these to pinpoint areas where they're needed most, saving people and whole regions. It could be a while before emergency teams are pulling up satellite views at a moment's notice, but it won't be surprising if aircraft-based fire recon eventually becomes obsolete.

  • An F1 racer burning rubber in infrared is trippy

    FLIR has just shown a dramatic spectrum of Formula 1 racing you may not have even realized you were missing: full infrared. The company filmed Red Bull's RB8 F1 car doing donuts at the Gamma Racing Day in Assen using its FLIR X6580sc and other infrared cameras. As shown in the video below, the drivers are literally surrounded by flames and heat coming off the tires, engine and exhaust. You can also see the still glowing tracks left by the tires, Back to the Future style, and the hot bits of rubber that flew off. The only thing missing is the smoke, which is a good thing -- as shown by a regular camera, it almost completely covers the car at one point.

    As convenient as touchscreens and air gesture controls can be on a PC, it's not very comfortable to keep raising your hands just to handle basic tasks. You might not have to subject your arms to that kind of strain if Microsoft's experimental Type-Hover-Swipe keyboard ever reaches shelves, though. The peripheral hides a grid of infrared motion sensors between the keys, letting you perform hand gestures in a more natural position. While the technology is very low-resolution (there's just 64 pixels of data), it's both fast and precise enough to recognize more advanced commands. Among other tricks, you can mimic a steering wheel with your hands when playing a racing game.

    Keeping a steady hand when snapping panoramic pictures is a valuable skill, but NASA's upstaged your photographic prowess with something a tad more impressive. Using over 2 million infrared pictures shot with the Spitzer Space Telescope over the course of a decade, the agency's created what's being called the clearest infrared panorama of our galaxy ever made. This is the first time all photographs from a project dubbed the Galactic Legacy Mid-Plane Survey Extraordinaire (or GLIMPSE360) have been combined into a single image. Although the final product only shows three percent of the sky, it contains over half of all stars in the Milky Way.

    When we last saw Grippity, it wasn't much more than a pretty media center keyboard. Well, it just grew up -- its creators have revived the concept as a full-fledged, crowdfunded Android tablet. The new design still centers on a transparent, dual-sided touch surface, but there's now more to do than type. The PS Vita-style back control lets users tap interface elements without obscuring the screen, and it opens the door to more complex multi-touch gestures. The infrared remote control and thumbpads have also returned from Grippity's previous incarnation. If you're intrigued, you can pledge $235 ($159 for a few early birds) to Grippity's Kickstarter campaign to reserve a tablet for yourself; provided the team reaches its funding goal, you should have the device in your hands by October.
