Reaching extreme temperatures, the battery is able to shut itself down, only restarting once it has cooled. The researchers designed the battery to shut down and restart itself over a repeated heating and cooling cycle, without compromising performance. A polyethylene film is applied to one of the electrodes, which expands and shrinks depending on temperature, to create a conductive/non-conductive material.

That seems to be the thinking behind Planetary Resources' recent presentation at CES in Las Vegas, where the asteroid mining company unveiled the first object 3D printed using extraterrestrial materials. Made in collaboration with 3D Systems, the nickel-iron sculpture represents a stylized, geometric spacecraft, such as might be used for asteroid mining or prospecting. Planetary Resources says it is representative of what could be printed in a weightless environment.

chalsall writes: Intel has confirmed an in-the-wild bug that can freeze its Skylake processors. The company is pushing out a BIOS fix. Ars reports: "No reason has been given as to why the bug occurs, but it's confirmed to affect both Linux and Windows-based systems. Prime95, which has historically been used to benchmark and stress-test computers, uses Fast Fourier Transforms to multiply extremely large numbers. A particular exponent size, 14,942,209, has been found to cause the system crashes. While the bug was discovered using Prime95, it could affect other industries that rely on complex computational workloads, such as scientific and financial institutions. GIMPS noted that its Prime95 software "works perfectly normal" on all other Intel processors of past generations."

While malware was used to gain access to networks, the attackers then opened circuit breakers that cut power, according to information published Saturday by the SANS Industrial Control Systems (ICS) team. The attackers used direct intervention to try to mask their actions to the power systems operators and also conducted denial-of-service attacks on the utilities' phone systems to block complaints from affected customers, SANS said.

(Here's one of the many, many tutorials out there on doing it yourself; it's not the long-forgotten one I actually used, but I like this one better.) I like listening to recorded music sometimes just to hear how a particular playback system sounds, not just to hear the music "as intended." I'd like to find some more audio hacks and tricks like this that are cheap, easy, and fun. Bonus points if they can be done with the assistance of a couple of smart children, without boring them too much. I have access to Goodwill and other thrift stores that are usually overflowing with cheap-and-cheerful gear, to match my toy budget. What mods or fixes would be fun to implement? Are there brands or models of turntable I should look for as the easiest with which to tinker? Are there cool easy-entry projects akin to that surround sound system that I could use to improve my radio reception? I'm not sure what's out there, but I'd like to get some cool use out of the closet-and-a-half I've got filled with speakers and other gear that I can't quite bear to toss, since "it still works."

mdsolar writes: Climatologist James Hansen argued last month, "Nuclear power paves the only viable path forward on climate change." He is wrong. As the Nuclear Energy Agency (NEA) and International Energy Agency (IEA) explained in a major report last year, in the best-case scenario, nuclear power can play a modest, but important, role in avoiding catastrophic global warming if it can solve its various nagging problems — particularly high construction cost — without sacrificing safety. Hansen and a handful of other climate scientists I also greatly respect — Ken Caldeira, Tom Wigley, and Kerry Emanuel — present a mostly handwaving argument in which new nuclear power achieves and sustains an unprecedented growth rate for decades. The one quantitative "illustrative scenario" they propose — "a total requirement of 115 reactors per year to 2050 to entirely decarbonise the global electricity system" — is far beyond what the world ever sustained during the nuclear heyday of the 1970s, and far beyond what the overwhelming majority of energy experts, including those sympathetic to the industry, think is plausible.

MojoKid writes: Solid State Drive technology continues to make strides in performance, reliability and cost. At the CES 2016 show there were a number of storage manufacturers on hand showing off their latest grear, though not many made quite the splash that Toshiba's OCZ Technology group made with the annoucement of their new RevoDrive 400 NVMe PCI Express SSD. OCZ is tapping on Toshiba's NVMe controller technology to deliver serious bandwidth in this consumer-targeted M.2 gumstick style drive that also comes with a X4 PCI Express card adapater. The drive boasts specs conservatively at 2.4GB/sec for reads and 1.6GB/sec for writes in peak sequential transfer bandwidth. IOPs are rated at 210K and 140K for writes respectively. In the demo ATTO test they were running, the RevoDrive 400 actually peaks at 2.69GB/sec for reads and also hits every bit of that 1.6GB/sec write spec for large sequential transfers.

An anonymous reader writes: A project called 'Gridstrike' found that free and publicly available information can be used to determine the most critical electric substations in the US, which if attacked, could result in a nationwide blackout. Researchers from iSIGHT Partners used a combination of publicly available transmission substation information, maps, Google Earth, and grid congestion documentation, and drew correlations among the substations that serve the top ten cities in the US. They ID'ed 15 substations that if attacked and knocked offline would result in a nationwide blackout, they say. Their research took the spin of whether a homegrown terror group with little funding could get this crucial information. The study was inspired by the 2013 Federal Energy Regulatory Commission (FERC) study in 2013 that found that attacks on just nine electric substations in the U.S. could cause a blackout across the entire grid.

Project Tango is Google's vision to bring augmented reality to phones by enabling devices to be able to sense where they are and what is around them. During the announcement, Google's Johnny Lee demonstrated measuring a room using a prototype Project Tango tablet and then shopping at Lowes for furniture that would fit it. Google also announced an app incubator for Project Tango, which they hope will encourage developers to start building apps that make use of the AR technology.

Infections occur via applications downloaded from a series of sites ran under the H.TV brand. These are websites that offer applications specifically built for Android smart TVs that allow users to watch TV channels from other regions of the globe. As usual, these apps are side-loaded from unofficial app stores. Fortunately, it's not a smart TV ransomware.

MojoKid writes: Intel is taking another stab at the PC-in-your-pocket form factor with their next gen Compute Sticks. These over-sized thumbstick devices plug into the HDMI port of any TV or monitor and offer a full-fledged computing experience and Intel has now made them faster and more capable. New for 2016, there are three new base model Compute Sticks to choose from. The first is an entry-level option running a quad-core Atom x5-z8400 quad-core processor clocked at 1.44GHz to 2.24GHz with 2GB of RAM, 32GB of eMMC storage, a pair of USB ports, 802.11ac Wi-Fi, and Windows 10. But perhaps more interesting are the new 6th Generation Intel Core M models. The higher end of the two is powered by a Skylake Core m5-6Y57 vPro processor while the lower end version is equipped with a Core m3-6Y30. Both models boast 4GB of DDR3-1866 RAM, 64GB of eMMC storage expandable via microSD card slot, 802.11ac Wi-Fi, and three USB 3.0 ports (one on the Compute Stick and two on the power adapter). Without an OS, the Core m3 model runs $300; Windows 10 adds $100 to the price tag. The Core m5 Compute Stick will run $500 and, at least for now, doesn't appear to offer a version with Windows 10 pre-installed. The new Compute Sticks will be available in February.

itwbennett writes: A couple of years ago, Facebook revealed it was using Blu-ray disks as a cost-efficient way to archive the billions of images that users uploaded to its service. When Facebook users upload photos, they're often viewed frequently in the first week, so Facebook stores them on solid state drives or spinning hard disks. But as time goes on the images get viewed less and less. At a certain point, Facebook dumps them onto high-capacity Blu ray discs, where they might sit for years without being looked at. Now, Panasonic has said it plans to commercialize the technology for other businesses, and is working on new disks that will hold a terabyte of data.

operator_error writes: Verizon has now chosen to reverse "its strategy to expand in hosting and colocation services after it acquired data center operator Terremark Worldwide Inc in 2011 for $1.4 billion", and has "started a process to sell its data center assets". The so-called 'colocation' portfolio up for sale includes 48 data centers, and generates annual earnings before interest, tax, depreciation and amortization of around $275 million. The enterprise telecommunications industry has had to adapt in recent years to corporate customers seeking more sophisticated and cheaper offerings to manage their data. Verizon joins a host of its rivals in telecommunications who are shedding their data centers.

Api.ai makes an Android voice-controlled utility called Assistant. I have it on my Android phone. It is one of many simiar apps, and I have been trying them a little at a time. Are any of them as good as Siri? Let's just say, "Quality varies."

And Android voice assistants aren't the point of this interview, anyway. It's more about the process of developing interactive, voice-based IO systems. This whole voice/response thing is an area that's going to take off any year now -- and has been in that state for several decades -- but may finally be going somewhere, spurred by intense competition between the many companies working in this field, including Ilya's.

New submitter jerome writes: Pre-orders have just started for the Oculus Rift virtual reality headset. The $600 price tag is higher than most people were expecting — and that doesn't even account for the required upgrade needed to fully enjoy VR apps. "In September of 2014, Oculus founder Palmer Luckey said to expect a $200 to $400 range for the Rift." The device will first begin shipping on March 28th, though the store is already showing an estimate of April for Rifts beyond the initial stock. "The Rift package also doesn't include the relatively powerful Windows PC that will be required to use the device. Oculus recommends a rig with an Nvidia GTX 970 (or equivalent), an Intel i5 processor, and at least 8GB of RAM." In February, they'll start taking pre-orders for a package that does include a full, "Oculus-ready" system for $1500.

bricko notes a report on what appears to be the first power outage known to have been caused by hackers: Highly destructive malware that infected at least three regional power authorities in Ukraine led to a power failure that left hundreds of thousands of homes without electricity last week, researchers said. ... On Monday, researchers from security firm iSIGHT Partners said they had obtained samples of the malicious code that infected at least three regional operators. They said the malware led to "destructive events" that in turn caused the blackout. If confirmed it would be the first known instance of someone using malware to generate a power outage.

Over the past year, the group behind BlackEnergy has slowly ramped up its destructive abilities. Late last year, according to an advisory from Ukraine's Computer Emergency Response Team, the KillDisk module of BlackEnergy infected media organizations in that country and led to the permanent loss of video and other content. The KillDisk that hit the Ukrainian power companies contained similar functions but was programmed to delete a much narrower set of data, ESET reported. KillDisk had also been updated to sabotage two computer processes, including a remote management platform associated with the ELTIMA Serial to Ethernet Connectors used in industrial control systems.

Press2ToContinue writes: When Gene Roddenberry's computer died, it took with it the only method of accessing some 200 floppy disks of his unpublished work. To make matters worse, about 30 of the disks were damaged, with deep gouges in the magnetic surface. "Cobb said a few of the disks were formatted in DOS, but most of them were from an older operating system called CP/M. CP/M, or Control Program for Microcomputers, was a popular operating system of the 1970s and early 1980s that ultimately lost out to Microsoft's DOS. In the 1970s and 1980s it was the wild west of disk formats and track layouts, Cobb said. The DOS recoveries were easy once a drive was located, but the CP/M disks were far more work. " So what was actually on the disks? Lost episodes of Star Trek? The secret script for a new show? Or as Popular Science once speculated, a patent for a transporter?

Unfortunately, we still don't know. The Roddenberry estate hasn't commented yet, and the data recovery agency is bound by a confidentiality agreement.

Advocatus Diaboli sends a report from Glenn Greenwald at The Intercept about the NSA's efforts to subvert encryption. Back in 2013, several major publications reported that the NSA was able to crack encryption surrounding commerce and banking systems. Their reports did not identify which specific technology was affected. The recent backdoor found in Juniper systems has caused the journalists involved to un-redact a particular passage from the Snowden documents indicating the NSA targeted the "two leading encryption chips" in their attempts to compromise encryption. Quoting: The reference to "the two leading encryption chips" provides some hints, but no definitive proof, as to which ones were successfully targeted. Matthew Green, a cryptography expert at Johns Hopkins, declined to speculate on which companies this might reference. But he said that "the damage has already been done. From what I've heard, many foreign purchasers have already begun to look at all U.S.-manufactured encryption technology with a much more skeptical eye as a result of what the NSA has done. That's too bad, because I suspect only a minority of products have been compromised this way."
