The device's inventors suggest the laser could find use in video displays, solid-state lighting, and a laser-based version of Wi-Fi. Although previous research has created red, blue, green and other lasers, each of these lasers usually only emitted one color of light. Creating a monolithic structure capable of emitting red, green, and blue all at once has proven difficult because it requires combining very different semiconductors. Growing such mismatched crystals right next to each other often results in fatal defects throughout each of these materials. But now scientists say they've overcome that problem. The heart of the new device is a sheet only nanometers thick made of a semiconducting alloy of zinc, cadmium, sulfur, and selenium. The sheet is divided into different segments. When excited with a pulse of light, the segments rich in cadmium and selenium gave off red light; those rich in cadmium and sulfur emitted green light; and those rich in zinc and sulfur glowed blue.

It is built for professional content creators and the company hopes the camera will become the leading device for shooting virtual-reality experiences for Hollywood. A formal launch and price announcement is planned for the fall. A Nokia press release reads in part: "OZO captures stereoscopic 3D video through eight (8) synchronized global shutter sensors and spatial audio through eight (8) integrated microphones. Software built for OZO enables real-time 3D viewing, with an innovative playback solution that removes the need to pre-assemble a panoramic image - a time-consuming process with solutions currently in the marketplace. OZO's filmed content can be published for commercially available VR viewing hardware such as head mounted displays (HMDs), with immersive, full 360-degree imaging and spatially accurate original sound. OZO also integrates into existing professional workflows and works with third-party tools, dramatically simplifying content production at all stages."

Mickeycaskill writes: Cambridge Electronics Inc (CEI), formed of researchers from the Massachusetts Institute of Technology (MIT), claim semiconductors made of gallium nitride (GaN) could reduce the power consumption of data centers and consumer electronics by 20 percent by 2025. CEI has revealed a range of GaN transistors and power electronic circuits that have just one tenth of the resistance of silicon, resulting in much higher energy efficiency. The company claims to have overcome previous barriers to adoption such as safety concerns and expense through new manufacturing techniques. "Basically, we are fabricating our advanced GaN transistors and circuits in conventional silicon foundries, at the cost of silicon. The cost is the same, but the performance of the new devices is 100 times better," Cambridge Electronics researcher Bin Lu said.

Esther Schindler writes: The developers at .io are into tracking things, I guess. In any case, a few weeks back they decided to track team performance in terms of keyboard and mouse activity during the working day. They installed a simple Chrome plugin on every Macbook and collected some statistics. For instance, developers have fewer keypresses than editors and managers—around 4k every day. Managers type more than 23k characters per day. And so on. Some pretty neat statistics.

But the piece that jumped out at me was this: "What's curious—the least popular keys are Capslock and Right Mouse Button. Somewhere around 0.1% of all keypresses together. It's time to make some changes to keyboards." I've been whining about this for years. Why is it that the least-used key on my keyboard is not just in a prominent position, but also bigger than most other keys? I can I invest in a real alternate keyboard with a different layout (my husband's a big fan of the Kinesis keyboards, initially to cope with carpal tunnel). But surely it's time to re-visit the standard key layout? What keys would you eliminate or re-arrange?

SlappingOysters writes: This article takes a closer look at the emerging crowdfunding platform Sprked, which aims to follow the Patreon support model, but exclusively for video game modders. The service is currently in its early stages, but by crafting a system of appreciation and support that acknowledges the loyalty of the modding community, Sprked has the potential to promote and foster the creativity that is so integral to modding, instead of hampering it with the murky baggage of a mandatory economy. Valve's attempt to let modders make some money for their efforts backfired within the community — there are four demons the paid mods plan must slay to actually work.

itwbennett writes: Just days after publication of a flaw in Android's Stagefright, which could allow attackers to compromise devices with a simple MMS message, researchers have found another Android media processing flaw. The latest vulnerability is located in Android's mediaserver component, more specifically in how the service handles files that use the Matroska video container (MKV), Trend Micro researchers said. "When the process opens a malformed MKV file, the service may crash (and with it, the rest of the operating system). The vulnerability is caused by an integer overflow when the mediaserver service parses an MKV file. It reads memory out of buffer or writes data to NULL address when parsing audio data."

McGruber writes: Hillview, Kentucky resident William H. Merideth describes his weekend: "Sunday afternoon, the kids – my girls – were out on the back deck, and the neighbors were out in their yard. And they come in and said, 'Dad, there's a drone out here, flying over everybody's yard.'" Merideth's neighbors saw it too. "It was just hovering above our house and it stayed for a few moments and then she finally waved and it took off," said neighbor Kim VanMeter. Merideth grabbed his shotgun and waited to see if the drone crossed over his property. When it did, he took aim and shot it out of the sky.

The owners showed up shortly, and the police right after. He was arrested and charged with first degree criminal mischief and first degree wanton endangerment before being released the next day. Merideth says he will pursue legal action against the drone's owner: "He didn't just fly over. If he had been moving and just kept moving, that would have been one thing -- but when he come directly over our heads, and just hovered there, I felt like I had the right. You know, when you're in your own property, within a six-foot privacy fence, you have the expectation of privacy. We don't know if he was looking at the girls. We don't know if he was looking for something to steal. To me, it was the same as trespassing."

An anonymous reader writes: It was inevitable: as soon as we heard about computer-aimed rifles, we knew somebody would find a way to compromise their security. At the upcoming Black Hat security conference, researchers Runa Sandvik and Michael Auger will present their techniques for doing just that. "Their tricks can change variables in the scope's calculations that make the rifle inexplicably miss its target, permanently disable the scope's computer, or even prevent the gun from firing." In one demonstration they were able to tweak the rifle's ballistic calculations by making it think a piece of ammunition weighed 72 lbs instead of 0.4 ounces. After changing this value, the gun tried to automatically adjust for the weight, and shot significantly to the left. Fortunately, they couldn't find a way to make the gun fire without physically pulling the trigger.
