TrueCrypt Audit Back On Track After Silence and Uncertainty

itwbennett writes: In October 2013 Cryptography professor Matthew Green and security researcher Kenneth White launched a project to perform a professional security audit of TrueCrypt, partly prompted by the leaks from Edward Snowden that suggested the NSA was engaged in efforts to undermine encryption. Their report, published in April 2014, covered the first phase of the audit. Phase two was supposed to involve a formal review of the program’s encryption functions, with the goal of uncovering any potential errors in the cryptographic implementations—but then the unexpected happened. In May 2014, the developers of TrueCrypt, who had remained anonymous over the years for privacy reasons, abruptly announced that they were discontinuing the project and advised users to switch to alternatives. Now, almost a year later, the project is back on track. Read more of this story at Slashdot.

Resistant Bacterial Infection Outbreak At California Hospital

puddingebola writes From the article: “A potentially deadly “superbug” resistant to antibiotics has infected seven patients, including two who died, and more than 160 others were exposed at Ronald Reagan UCLA Medical Center through contaminated medical instruments, the hospital revealed. The drug-resistant superbug known as CRE was likely transmitted to the Los Angeles patients by contaminated medical scopes during endoscopic procedures that took place between October 2014 and January 2015, a university statement said. ” UCLA says the infections occurred via contaminated endoscopes that were sterilized according to the manufacturer’s specifications.

Samsung’s Portable SSD T1 Tested

MojoKid writes The bulk of today’s high-capacity external storage devices still rely on mechanical hard disk drives with spinning media and other delicate parts. Solid state drives are much faster and less susceptible to damage from vibration, of course. That being the case, Samsung saw an opportunity to capitalize on a market segment that hasn’t seen enough development it seems–external SSDs. There are already external storage devices that use full-sized SSDs, but Samsung’s new Portable SSD T1 is more akin to a thumb drive, only a little wider and typically much faster. Utilizing Samsung’s 3D Vertical NAND (V-NAND) technology and a SuperSpeed USB 3.0 interface, the Portable SSD T1 redlines at up to 450MB/s when reading or writing data sequentially, claims Samsung. For random read and write activities, Samsung rates the drive at up to 8, 000 IOPS and 21, 000 IOPS, respectively. Pricing is more in-line with high-performance standalone SSDs, with this 1TB model reviewed here arriving at about $579. In testing, the drive did live up to its performance and bandwidth claims as well. Read more of this story at Slashdot.

Storing Data In Synthetic Fossils

Bismillah tips news of research from ETH Zurich which brings the possibility of extremely long-term data storage. The scientists encoded data in DNA, a young but established technique that has a major problem: accuracy. “[E]ven a short period of time presents a problem in terms of the margin of error, as mistakes occur in the writing and reading of the DNA. Over the longer term, DNA can change significantly as it reacts chemically with the environment, thus presenting an obstacle to long-term storage.” To get around this issue, they encapsulated the DNA within tiny silica spheres, a process roughly comparable to the fossilization of bones (abstract). The researchers say data can be preserved this way for over a million years. Read more of this story at Slashdot.

HTTP/2 Finalized

An anonymous reader writes: Mark Nottingham, chair of the IETF HTTP working group, has announced that the HTTP/2 specification is done. It’s on its way to the RFC Editor, along with the HPACK specification, where it’ll be cleaned up and published. “The new standard brings a number of benefits to one of the Web’s core technologies, such as faster page loads, longer-lived connections, more items arriving sooner and server push. HTTP/2 uses the same HTTP APIs that developers are familiar with, but offers a number of new features they can adopt. One notable change is that HTTP requests will be ‘cheaper’ to make. … With HTTP/2, a new multiplexing feature allows lots of requests to be delivered at the same time, so the page load isn’t blocked.” Here’s the HTTP/2 FAQ, and we recently talked about some common criticisms of the spec.

Breakthrough In Face Recognition Software

An anonymous reader writes: Face recognition software underwent a revolution in 2001 with the creation of the Viola-Jones algorithm. Now, the field looks set to dramatically improve once again: computer scientists from Stanford and Yahoo Labs have published a new, simple approach that can find faces turned at an angle and those that are partially blocked by something else. The researchers “capitalize on the advances made in recent years on a type of machine learning known as a deep convolutional neural network. The idea is to train a many-layered neural network using a vast database of annotated examples, in this case pictures of faces from many angles. To that end, Farfade and co created a database of 200, 000 images that included faces at various angles and orientations and a further 20 million images without faces. They then trained their neural net in batches of 128 images over 50, 000 iterations. … What’s more, their algorithm is significantly better at spotting faces when upside down, something other approaches haven’t perfected.” Read more of this story at Slashdot.

Nanotech Makes Steel 10x Stronger

An anonymous reader writes: A new metal-making process currently in testing at oil fields uses nano-scale plating to make metals like steel as much as ten times stronger than they would be without it. “[The process] uses an advanced form of electroplating, a process already used to make the chrome plating you might see on the engine and exhaust pipes of a motorcycle. Electroplating involves immersing a metal part in a chemical bath containing various metal ions, and then applying an electrical current to cause those ions to form a metal coating. The company uses a bath that contains more than one kind of metal ion and controls how ions are deposited by varying the electrical current. By changing the current at precise moments, it can create a layered structure, with each layer being several nanometers thick and of different composition. The final coating can be up to a centimeter thick and can greatly change the properties of the original material.” Read more of this story at Slashdot.

Federal Study: Marijuana Use Doesn’t Increase Auto Crash Rates

An anonymous reader writes: After the legalization of marijuana in multiple states around the U.S., many are worried about a corresponding uptick in car crashes as people drive while under the influence of pot. But according to a new federal study (PDF) commissioned by the National Highway Traffic Safety Administration, those fears seem unfounded. They report that after adjusting for other factors (people who tend to drive after using marijuana also tend to be more crash-prone in general), there was no statistically significant increase in crash rates by drivers who tested positive for the drug. It’s still a bad idea to drive high, but driving drunk is far, far worse: “One substance was shown to have a major influence on crashes: alcohol. The study confirmed the enormous danger of drinking and driving, even after age and sex adjustment: drivers with a 0.05% blood-alcohol level were found to be twice as likely to be in a crash. For a person weighing 180 to 190 pounds, that could be a single can of beer, glass of wine, or shot of liquor. At 0.08% (two drinks), the likelihood is quadrupled, and at .20% (four drinks or more), the risk is higher by 23 times.” Read more of this story at Slashdot.

Canada’s Next-Generation Military Smart Gun Unveiled

Zothecula writes Looking every bit like a weapon from a science fiction movie, the latest integrated assault rifle prototype being developed for the Canadian Armed Forces (CAF) is packed with some very smart weapons technology. Along with the ability to fire new lightweight telescoped ammunition, and a secondary effects module that adds either a three-round 40 mm grenade launcher or a 12-gauge shotgun, there is also a NATO-standard power and data bus to allow the attachment of smart accessories, such as electro-optical sights and position sensors that connect to command and control networks.

Researcher Developing Tattoo Removal Cream

BarbaraHudson writes During tattooing, ink is injected into the skin, initiating an immune response, and cells called “macrophages” move into the area and “eat up” the ink. The macrophages carry some of the ink to the body’s lymph nodes, but some that are filled with ink stay put, embedded in the skin. That’s what makes the tattoo visible under the skin. Dalhousie Uiversity’s Alec Falkenham is developing a topical cream that works by targeting the macrophages that have remained at the site of the tattoo. New macrophages move in to consume the previously pigment-filled macrophages and then migrate to the lymph nodes, eventually taking all the dye with them. “When comparing it to laser-based tattoo removal, in which you see the burns, the scarring, the blisters, in this case, we’ve designed a drug that doesn’t really have much off-target effect, ” he said. “We’re not targeting any of the normal skin cells, so you won’t see a lot of inflammation. In fact, based on the process that we’re actually using, we don’t think there will be any inflammation at all and it would actually be anti-inflammatory.” Read more of this story at Slashdot.
