4K Displays Ready For Prime Time

An anonymous reader writes “After the HD revolution, display manufacturers rolled out gimmick after gimmick to try to recapture that burst of purchasing (3-D, curved displays, ‘Smart’ features, form factor tweaks, etc). Now, we’re finally seeing an improvement that might actually be useful: 4K displays are starting to drop into a reasonable price range. Tech Report reviews a 28″ model from Asus that runs $650. They say, ‘Unlike almost every other 4K display on the market, the PB287Q is capable of treating that grid as a single, coherent surface. … Running games at 4K requires tons of GPU horsepower, yet dual-tile displays don’t support simple scaling. As a result, you can’t drop back to obvious subset resolutions like 2560×1440 or 1920×1080 in order to keep frame rendering times low. … And single-tile 4K at 30Hz stinks worse, especially for gaming. The PB287Q solves almost all of those problems.’ They add that the monitor’s firmware is not great, and while most options you want are available, they often require digging through menus to set up. The review ends up recommending the monitor, but notes that, more importantly, its capabilities signify ‘the promise of better things coming soon.'” Read more of this story at Slashdot.

Next IE Version Will Feature Web Audio, Media Capture, ES6 Promises, and HTTP/2

An anonymous reader writes “Microsoft [Wednesday] announced it is developing at least four new features for the next release of Internet Explorer (IE): Web Audio API, Media Capture and Streams, ES6 Promises, and HTTP/2. The company says this is not an exhaustive list of what to expect in the next version, but merely what it is currently confident that it will be able to deliver. For those who don’t know, HTTP/2 is a faster protocol for transporting Web content. It is based on Google’s SPDY open networking protocol and is currently being standardized by the IETF. Web Audio is a JavaScript API for processing and synthesizing audio in Web applications while Media Capture provides access to the user’s local audio and video input/output devices. Promises is meant to help developers write cleaner asynchronous code.” Read more of this story at Slashdot.

A Simple Blast of Laser Could Help Your Teeth Grow Back

Teeth don’t grow back, as your dentist might like to remind you while revving up the drill for a root canal. But scientists have now found a way to regenerate dentin , the hard stuff in the middle of the tooth, right in the mouth. It’s surprisingly simple, too—all it takes is a blast of laser. Read more…

Quad Lasers Deliver Fast, Earth-Based Internet To the Moon

A joint project involving NASA and MIT researchers had demonstrated technology that could supply a lunar colony with broadband via lasers (“faster Internet access than many U.S. homes get”) and has already demonstrated its worth in communications with spacecraft. From ComputerWorld’s article: “The Lunar Laser Communication Demonstration (LLCD) kicked off last September with the launch of NASA’s LADEE (Lunar Atmosphere and Dust Environment Explorer), a research satellite now orbiting the moon. NASA built a laser communications module into LADEE for use in the high-speed wireless experiment. LLCD has already proved itself, transmitting data from LADEE to Earth at 622Mbps (bits per second) and in the other direction at 19.44Mbps, according to MIT. It beat the fastest-ever radio communication to the moon by a factor of 4, 800.” Communicating at such distances means overcoming various challenges; one of the biggest is the variability in Earth’s atmosphere. The LLCD doesn’t try to power through the atmosphere at only one spot, therefore, but uses four separate beams in the New Mexico desert, each aimed “through a different column of air, where the light-bending effects of the atmosphere are slightly different. That increases the chance that at least one of the beams will reach the receiver on the LADEE. Test results have been promising, according to MIT, with the 384, 633-kilometer optical link providing error-free performance in both darkness and bright sunlight, through partly transparent thin clouds, and through atmospheric turbulence that affected signal power.” Read more of this story at Slashdot.

New Middleware Promises Dramatically Higher Speeds, Lower Power Draw For SSDs

mrspoonsi (2955715) writes “A breakthrough has been made in SSD technology that could mean drastic performance increases due to the overcoming of one of the major issues in the memory type. Currently, data cannot be directly overwritten onto the NAND chips used in the devices. Files must be written to a clean area of the drive whilst the old area is formatted. This eventually causes fragmented data and lowers the drive’s life and performance over time. However, a Japanese team at Chuo University have finally overcome the issue that is as old as the technology itself. Officially unveiled at the 2014 IEEE International Memory Workshop in Taipei, the researchers have written a brand new middleware for the drives that controls how the data is written to and stored on the device. Their new version utilizes what they call a ‘logical block address scrambler’ which effectively prevents data being written to a new ‘page’ on the device unless it is absolutely required. Instead, it is placed in a block to be erased and consolidated in the next sweep. This means significantly less behind-the-scenes file copying that results in increased performance from idle.” Read more of this story at Slashdot.

Four Weeks Without Soap Or Shampoo

An anonymous reader writes “A biotech start-up from Massachusetts has an unusual product: a bottle full of bacteria you’re supposed to spray onto your face. The bacteria is Nitrosomonas eutropha, and it’s generally harmless. Its main use is that it oxidizes ammonia, and the start-up’s researchers suspect it used to commonly live on human skin before we began washing it away with soaps and other cleaners. Such bacteria are an area of heavy research in biology right now. Scientists know that the gut microbiome is important to proper digestion, and they’re trying to figure out if an external microbiome can be similarly beneficial to skin. A journalist for the NY Times volunteered to test the product, which involved four straight weeks of no showers, no soap, no shampoo, and no deodorant. The sprayed-on bacteria quickly colonized her skin, along with other known types of bacteria — and hundreds of unknown (but apparently harmless) strains. She reported improvements to her skin and complexion, and described how the bacteria worked to curtail (but not eliminate) the body odor caused by not washing. At the end of the experiment, all of the N. eutropha vanished within three showers.” Read more of this story at Slashdot.

Google Overtakes Apple As the World’s Most Valuable Brand

mrspoonsi (2955715) writes in with news that global market research agency Millward Brown has proclaimed Google as the world’s most valuable brand. “US search engine Google has overtaken rival technology titan Apple as the world’s top brand in terms of value, global market research agency Millward Brown said Wednesday. Google’s brand value shot up 40 percent in a year to $158.84 billion (115 billion euros), Millward Brown said in its 2014 100 Top BrandZ report. ‘Google has been extremely innovative this year with Google Glass, investments in artificial intelligence and a range of partnerships, ‘ said Benoit Tranzer, the head of Millward Brown France. Apple, which dominated the top position for three straight years, saw its brand value fall by 20 percent to $147.88 billion.” Read more of this story at Slashdot.

Almost 100 Arrested In Worldwide Swoop On Blackshades Malware

MattSparkes (950531) writes “Law enforcement around the world has teamed-up to arrest 97 for buying/using Blackshades malware, which can remotely seize control of a victim’s computer, access documents, record keystrokes and even activate their webcam to take surreptitious pictures and video. It is also able to encrypt files in order to extract a ransom for their release. Blackshades RAT is a commercial product costing less than $200 which was marketed as a tool to test network security. However, it is widely used by hackers and was even said by the Electronic Frontier Foundation to have been used against Syrian activists by the government in 2012.” Read more of this story at Slashdot.
