Video: Subaru bashes down a bobsled run



Years of rally success made Subaru a default choice for hoons in the early 2000s, but recent WRX models have struggled to meet (lofty) expectations. To build some hype for the current WRX STI, Subaru sat Mark Higgins in a specially-prepared car and told him to drive down the bobsled run in St. Moritz. As you might imagine, the results make for great viewing.

Charging your phone with a cooking pot New material could make it possible



Devices that generate electricity through the thermoelectric effect that is, the conversion of differences in temperature to an electric voltage are showing up in everything from clothing to paint, and they could go a long way towards reclaiming some of the heat lost during energy production. Now researchers at the University of Utah have developed a thermoelectric material that doesn't use the toxic chemicals common in others, but is still efficient and affordable enough for use in everyday products.

NASA's flat-packed Puffer robot unfurls for rugged terrain



NASA already has robots exploring the surface of Mars, but there are plenty of places these roaming science laboratories cannot go. One day a pint-sized rover may help fill in the blanks, with the space agency developing a flat-packed, shape-shifting two-wheeler that can not only handle rougher terrain, but can squeeze into confined spaces where organic molecules may be waiting to be discovered.

Infrared system could deliver 40 Gbps wireless networks



Wi-Fi works by sending information via radio waves, but systems that rely on light be it infrared or visible have the potential to achieve much faster speeds. A system proposed by a team at Eindhoven University of Technology (TU/e) uses infrared rays beamed down from antennas in the ceiling and is claimed to be capable of data transfer rates of over 40 Gbps, regardless of how many devices are hooking into the network.

Low-cost smartphone device seeks out Zika



Scientists have already used smartphones to combat the Zika virus, in the form of a grid computing system that puts idle processors to work searching for a cure, but new work from Sandia National Laboratories is a little more direct. A team there has developed a low-cost, portable device for quickly detecting Zika and similar viruses in a sample, driven by a smartphone app.

Curiosity's wheels are breaking down as the mileage adds up



NASA's Curiosity rover has been driving across Mars for over four-and-a-half years without an overhaul and it's starting to show. According to the space agency, the six aluminum wheels that support the unmanned explorer are starting to show significant signs of wear, with two new small breaks in the metal treads of the left-side middle wheel. However, it's expected the wheels will go the distance to allow the rover to complete its planned mission.

US Army arms combat vehicle with laser weapon to take on drones



The US Army seems to be keen on laser weapons these days. Not only is it taking delivery of a record 60-kW laser weapon, but it's also mounted a weapon-grade Army laser on a combat vehicle for the first time. Earlier this month, the US Army Space and Missile Defense Command/Army Forces Strategic Command (USASMDC/ARSTRAT) fielded a Stryker assault vehicle armed with a 5-kW laser as part of the Joint Improvised-Threat Defeat Organization (JIDO) UAS Hard-Kill Challenge at White Sands Missile Range, New Mexico.
