Silicon-laced diamonds could lead to practical quantum computers
Scientists already believe that diamonds could be a solid foundation for practical quantum computers. You can use atom-scale defects in diamond to store quantum bits that hold contradictory data (say, both on and off) in a way that lets you read the data without the risk of changing it. But there's a problem. The most common defect, where nitrogen atoms replace carbon atoms, emits such a broad range of light that it's too inaccurate to be useful. However, a team of researchers may have a way to keep those inaccuracies to a minimum: slip in some silicon, which emits a much narrower range of light.
Panasonic's indoor farm, and more in the week that was
Tesla's groundbreaking affordable electric car is nearly here. This week the automaker announced plans to begin production on the Model 3 by the end of the month. Meanwhile, environmental champion Leonardo DiCaprio just signed up as the official ambassador for BYD's new line of EVs. Georgia broke ground on a road paved with 18 miles of solar panels, and the tiny TigerMoth camper is an off-grid shelter that generates power while it's being towed.
A real suicide bomb detector should arrive this year
Ever since terrorism became an all-too-real fact of life, people have dreamed of suicide bomb detectors that spot an explosive vest before its wearer has a chance to detonate. However, making a working example has proven elusive. Some companies threw their hands up in frustration after developing systems that just weren't accurate enough. Others, meanwhile, didn't even try that hard -- the UK went so far as to ban some detectors that proved utterly ineffective. At last, though, it looks like a genuinely functional suicide bomb detector is on the horizon.
Sandia Labs' MegaDroid project simulates 300,000 Android phones to fight wireless catastrophes (video)
We've seen some large-scale simulations, including some that couldn't get larger. Simulated cellular networks are still a rare breed, however, which makes Sandia National Laboratories' MegaDroid project all the more important. The project's cluster of off-the-shelf PCs emulates a town of 300,000 Android phones down to their cellular and GPS behavior, all with the aim of tracing the wider effects of natural disasters, hacking attempts and even simple software bugs. Researchers imagine the eventually public tool set being useful not just for app developers, but for the military and mesh network developers -- the kind who'd need to know how their on-the-field networks are running even when local authorities try to shut them down. MegaDroid is still very much an in-progress effort, although Sandia Labs isn't limiting its scope to Android and can see its work as relevant to iOS or any other platform where a ripple in the network can lead to a tidal wave of problems.
Visualized: Sandia National Laboratories' Z machine erupts in a web of lightning
Sandia National Laboratories' Z machine sounds like it belongs in a James Bond movie more than it does an Alberquerque research facility. Based on what it can do, that's not as far-fetched as it seems. What you see isn't the handiwork of some electric spider -- it's what you witness in the immediate fraction of a second after the Z's electromagnetic pulse kicks in and forks of lightning burst across the 108-foot distance inside. The pulse in question is key to Sandia's studies of fusion and the effect of very intense magnetic pressures on materials that normally refuse to change states. Even in 2006, the Z was putting out pressure more than 10 million times that of the atmosphere, and it successfully melted diamond at roughly half that strength. It goes without saying that we don't want to be anywhere near this kind of energy when scientists flick the switch, but we're glad to see that something so pretty and deadly can help us understand physics.

Sandia National Laboratories generates neutrons in a radical way
The Responsive Neutron Generator Product Deployment Center (say that quickly five times) at Sandia Labs in Albuquerque, NM has discovered a way to take the conventional cylindrical tubes out of the equation and introduce a more computer-chip like, mass-produced neutron source on an astonishingly smaller scale. For those seeking lay terms, we're hearing that possible practical applications include implantation close to tumors in cancer patients to minimize time in the hospital for treatment, and sensors for contraband. Sandia Labs' technical staff has created what it calls a "neutristor," which produces one neutron per transistor, a concept that was directly inspired by the two transistors per bit on microchips. The team is currently seeking funding to ensure future viability, and well, to pay for stuff. Check out the video after the break, as well as further information at the source.
Sandia Labs develops self monitoring smart outlet, still needs you to plug it in
The folk at Sandia Labs work on all sorts of interesting projects, and the latest thing to fan our utopian dreams is this experimental smart power outlet. Unlike most monitoring set-ups, it can measure and control electric load without being connected to a central management system. The outlet comprises four receptacles, each with voltage and current sensors and a small computer which shuttles data over an Ethernet bridge. This autonomous style of operation could lead to more intelligent power grids that self-monitor, adapt and integrate with other grids without complex infrastructure updates. Other benefits include removing large points of failure, desirable in any network, and simpler home power monitoring systems. Sandia Labs' prototype could also improve effectiveness of variable output energy sources such as wind and solar, thanks to its ability to compensate for flux in energy production -- which might come in handy.
Gemini-Scout robot can scope out mining accidents, may save lives (video)
We've seen robots capable of entering hazardous nuclear plants and dangerous buildings, but engineers at Sandia Labs have now unveiled a new rescue bot that's explicitly designed to enter and investigate collapsed mines, as well. Measuring just two feet tall and less than four feet in length, the Gemini-Scout Mine Rescue Robot packs a set of gas sensors, a thermal camera and a two-way radio, allowing it to detect dangerous underground materials and relay critical information to above-ground rescue workers. Its can also navigate across rocky terrain, tight quarters, or flooded tunnels, and is sturdy enough to carry food and other supplies to trapped miners. Operators, meanwhile, can manipulate the Gemini-Scout using only an Xbox 360 controller, which was incorporated into the system on the strength of its intuitive design and UI. Sandia's engineers demoed their bot last week in DC and are hoping to begin licensing it to rescue agencies by the end of next year. Crawl past the break for a video of their creation, along with a full press release.
