Hasta La Gadget!

The universe is thought to be composed of stuff, non-stuff and maybe some other stuff. We’re referring, of course, to matter, anti-matter and as-yet illusive dark matter. While we know a fair amount about matter and its opposite, dark matter is still largely theoretical. That might change in around half an hour, though, as folks from NASA, MIT and the US Department of Energy hold a press conference to explain exactly what the Alpha Magnetic Spectrometer (AMS) strapped to the ISS has been seeing during almost two years of space-scanning. Samuel Ting from MIT, who will be on the panel, implied back in February that today’s results will provide the first evidence of dark matter’s existence — if that’s the right term. The press conference is due to start at 1:30PM EDT, so make sure to tune in to the NASA TV livestream embedded below for what could be the biggest scientific news since Higgs and his boson.

For all of their advanced technologies, modern satellites still rely on low-bandwidth radio transmitters to communicate with ground control. But they could soon be upgraded to beyond broadband speeds once NASA’s new laser-based communication system prototype gets off the ground. More »

The bad news: just as much of the world is starting to get excited about the prospects of 3D printing, science is moving on to the world of 4D. The good news: in the future, you might not have to assemble that Ikea chair yourself. “4D printing” is the term cientists are using to refer to a technology that MIT’s Skylar Tibbits talked up during a recent TED appearance. The fourth “d” here is time, referring to an object that, once printed, is capable of changing shape (over time, naturally).

“Essentially the printing is nothing new,” Tibbits told the BBC. “It is about what happens after.” So far the concept has been demonstrated with thin strands of plastic, which, once added to water, form into a predetermined shape, using energy from the absorption. Suggested future applications involve furniture, pipes, bikes and buildings. First, however, scientists will have to demonstrate the technology on a larger structure, of course, and they’ll explore the possibility of other energy sources, like heat, sound and vibration.

Mobile image processing in itself isn’t special when even high dynamic range shooting is virtually instant, at least with NVIDIA’s new Tegras. A new low-power MIT chip, however, may prove its worth by being a jack of all trades that works faster than software. It can apply HDR to photos and videos through near-immediate exposure bracketing, but it can also produce natural-looking flash images by combining the lit photo with an unassisted shot to fill in missing detail. Researchers further claim to have automatic noise reduction that safeguards detail through bilateral filtering, an established technique that uses brightness detection to avoid blurring edges. If you’re wondering whether or not MIT’s work will venture beyond the labs, don’t — the project was financed by contract manufacturing giant Foxconn, and it’s already catching the eye of Microsoft Research. As long as Foxconn maintains interest through to production, pristine mobile photography won’t be limited to a handful of devices.

Back in 2011, MIT discovered that the Fisker Karma’s batteries only lost 10 percent of their battery life after 1,500 charges. Admittedly, the study didn’t examine the EV’s reliability, nor its tendency to spontaneously combust, but the MIT researchers did learn plenty about energy conservation in the process. Fast-forward to now, and YShape, a start-up spun off from that original research, is taking to Kickstarter to fund HeatMeter, a sensor that’s designed to measure the efficiency of fuel-based boilers.

While electricity usage meters are ten-a-penny, it isn’t so easy to find equivalents for gas, propane or oil-powered units. By measuring the vibrations in its casing, HeatMeter can tell you exactly how much energy has been used. Combine that data with your home size and average bill cost, and it’ll work out what you’re spending and how to use less. YShape, led by Radu Gogoana, needs $60,000 for the initial production run — and will offer you a discounted unit if you kick in $129 — or lifetime upgrades and support if you make it $149. Not convinced? Head on past the break for the video pitch.
