Department of Energy seizes $21 million reserve account from Fisker

Fisker just can't catch a break. As if enduring the layoffs of three out of every four employees and the resignation of its founder wasn't unsettling enough, it's now come to light that the Department of Energy recently confiscated the company's $21 million reserve account in an attempt to recoup some of the government's loan. Fisker's first payment on the $192 million federal loan was due Monday, but the Energy Department revealed that it actually took the money 12 days beforehand, simply due to the company's high risk of default -- a move it characterized as an "appropriate action on behalf of taxpayers." If you're thinking the writing's now on the wall, you're correct... the WSJ reports that Fisker has hired a bankruptcy attorney, and the company admits that it's actively in search of a new owner. Will luck swing in Fisker's favor next time around? Place your bets.

AMS detects excess of positrons, could suggest existence of dark matter

AMS detects excess of positrons, could suggest existence of dark matter

We've been waiting with bated breath all afternoon to find out what NASA, MIT and the Department of Energy has observed with the Alpha Magnetic Spectrometer. Well, we still don't quite understand the exact nature of dark matter, but highly precise measurements of positron fraction (the ratio of positrons to electrons and protons) do bring us a small step closer to proving the existence of the theoretical material. The AMS found a small excess of positrons coming from all directions instead of a single source. That could indicate the presence of dark matter, which is believed to generate the antimatter particles when it collides and annihilates itself. As usual though, this is far from conclusive. The excess of positrons could be caused by a number of cosmic phenomenon, including pulsars, but researchers are hopeful that further testing will narrow down the possibilities. Those of you hoping for direct and obvious evidence of dark matter may be a little disappointed, but let's be honest -- you were being overly optimistic. Besides, don't you want some mysteries left to solve? For more information, check out the PR after the break.

PSA: Watch the AMS dark matter results announcement at 1:30PM ET (video)

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.

NOvA neutrino detector captures cosmic rays in 3D, aims to unlock the mysteries of the universe

Posted on by

NOvA

All apologies accepted if you mistook that image above as cover art for Daft Punk's new album -- it's not (although the duo should consider it.). That Tron-ish, equalizer-like graphic is actually a 3D representation of particle activity left behind by cosmic rays interacting within NOvA, the Department of Energy's under construction neutrino detector. It's the first such visual record made possible by the University of Minnesota-operated facility that, when completed, will extend for more than 200 feet underground in an area near the Canadian border and endure regular bombardment by a controlled stream of neutrinos. Beyond its obvious visual appeal, data like this should give physicists at the DOE's Fermi National Accelerator Laboratory insight into the nature of neutrinos (some of which are said to have been issued from the Big Bang) and, by extension, the origins of our ever-expanding universe. For now, though, the project's still in the baby steps phase -- only 12 feet of the detector (the currently operational portion) has been successfully built out -- so the reality-shattering, scientific epiphanies will have to wait. Until then, it's all still life as we safely know it.

Elon Musk says Tesla will repay Department of Energy loan well before 2022 due date

Elon Musk says Tesla will repay Department of Energy loan well before deadline

Tesla's CEO, Elon Musk, has been the focus of many headlines lately due to a certain, well-documented kerfuffle with The New York Times. Today, however, the automotive company's chief isn't questioning any reviews. Instead, he's taken to the Advanced Research Projects Agency for Energy summit to share his belief that Tesla Motors will pay off that $465 million loan from the US Department of Energy well ahead of when it's expected to -- in five years, rather than ten, to be precise. Musk's comments shouldn't come as a surprise, however, given that the Model S maker has been paying its DOE-borrowed cash on time and before the deadlines -- something it's been able to accomplish despite being far from a money-making machine at the moment. For the Department of Energy, meanwhile, this all sounds like music to the ears, especially since it knows that not all EVs always work out as planned.

Researchers create algorithms that help lithium-ion batteries charge two times faster

Researchers create algorithms that help lithium-ion batteries charge two times faster

Researchers at the University of California San Diego have devised new algorithms that can cut lithium-ion battery charge times in half, help cells run more efficiently and potentially cut production costs by 25 percent. Rather than tracking battery behavior and health with the traditional technique of monitoring current and voltage, the team's mathematical models estimate where lithium ions are within cells for more precise data. With the added insight, the team can more accurately gauge battery longevity and control charging efficiency. The group was awarded $460,000 from the Department of Energy's ARPA-E research arm to further develop the algorithm and accompanying tech with automotive firm Bosch and battery manufacturer Cobasys, which both received the remainder of a $9.6 million grant. Wondering if the solution will ever find its way out of the lab? According to co-lead researcher Scott Moura, it'll see practical use: "This technology is going into products that people will actually use."

Microbial music: Using sound to represent data from the deep blue sea

Microbial music: Using sound to represent data from the deep blue sea

Science and music, many would say opposite sides of the same coin. Unless you're DOE biologist Peter Larsen at the Argonne National Laboratory, who would probably argue your legal tender has been double-headed all along. While Larsen is more likely to be studying the intricacies of microbes than Miles Davis, his latest work puts the two of them closer than ever before. Faced with the task of studying vast amounts of microbial data gathered from the English Channel, the biologist explored alternative ways of making sense of it all. While he could have made a spiffy set of charts, Larsen claims that there are certain parameters, like sunlight and temperature, that give the data a structure that lends itself to musical representation.

While classical music might seem the typical choice, due to the irregular nature of the data, the result is more free-form jazz, yet still surprisingly musical. If you were wondering if there is something particularly groovy about the microbes in the English Channel, there isn't. Larsen and his colleagues used a similar idea in previous work looking at the relationship between a plant and a fungus. This isn't the first time data has been "sonified," but these processes that might initially seem to have no relation to music, rhythm and melody, actually highlight the patterns in natural phenomena. Want to get down to the microbial beat? You can hear a sample at the more coverage link.

US launches first commercial tidal power project this summer, Maine to reap moon’s gravitational benefits

US launches first commercial tidal power project this summer, Maine to reap moon's gravitational benefits

Solar may be the green energy source that's been hogging the headlines lately, but there are other fossil-fuel free ways that can help meet society's electrical needs. One of these is tidal power, and the US is set to start harnessing the ocean's electricity-generating potential this summer with the TidGen Cobscook Bay project -- the first such commercial project in the States. Located just off the coast of Eastport, Maine, turbines will be placed in 50-100 feet deep water to take advantage of the 100 billion tons of water that flow in and out of Cobscook Bay each day. When the project goes live, it'll feed into the public power grid and generate enough juice to power between 75 and 100 homes, and the plan is to eventually install enough turbines to generate 3MW of power -- which should cover the needs of over 1,000 homes and businesses. There's more info, plus plenty of political self-congratulation in the source below.

Sick and tired of waiting around for some exascale computing? So's the Department of Energy. The agency has offered up a $12.4 million contract to NVIDIA as part of its FastForward program, an attempt help speed up exascale development. The chipmaker will be using the two-year contract to help develop architecture for an exascale computer that operates at a "reasonable power level," in order to "advance the frontiers of science." Possible implications for exascale computing include the study of climate change, development of efficient engines, the search for disease cures, according to NVIDIA -- not to mention "reasons of national security and economic competitiveness."
