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...

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...

Sandia Labs’ MegaDroid project simulates 300,000 Android phones to fight wireless catastrophes (video)

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

Visualized Sandia Labs' Z machine erupts in a web of EMP 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

Image

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.
