Breakthrough In LED Construction Increases Efficiency By 57 Percent

Slashdot - Fri, 26/09/2014 - 6:37pm
Zothecula writes: With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent.

NASA Expands Commercial Space Program

Slashdot - Fri, 26/09/2014 - 5:55pm
An anonymous reader writes: Just 10 days after NASA awarded multi-billion-dollar contracts to SpaceX and Boeing for future manned rocket launches, the agency announced today it is expanding its commercial space program to include contracts for delivery missions to the International Space Station. "Under the Commercial Resupply Services 2 RFP, NASA intends to award contracts with one or more companies for six or more flights per contract. As with current resupply flights, these missions would launch from U.S. spaceports, and the contracted services would include logistical and research cargo delivery and return to and from the space station through fiscal year 2020, with the option to purchase additional launches through 2024."

How Did the 'Berlin Patient' Rid Himself of HIV?

Slashdot - Fri, 26/09/2014 - 5:10pm
sciencehabit writes: Researchers are closer to unraveling the mystery of how Timothy Ray Brown, the only human cured of HIV, defeated the virus, according to a new study. Although the work doesn't provide a definitive answer, it rules out one possible explanation. [R]esearchers point to three different factors that could independently or in combination have rid Brown’s body of HIV. The first is the process of conditioning, in which doctors destroyed Brown’s own immune system with chemotherapy and whole body irradiation to prepare him for his bone marrow transplant. His oncologist, Gero Hütter, who was then with the Free University of Berlin, also took an extra step that he thought might not only cure the leukemia but also help rid Brown’s body of HIV. He found a bone marrow donor who had a rare mutation in a gene that cripples a key receptor on white blood cells the virus uses to establish an infection. (For years, researchers referred to Brown as "the Berlin patient.") The third possibility is his new immune system attacked remnants of his old one that held HIV-infected cells, a process known as graft versus host disease.

How the FLAC do I tell MP3s from lossless audio?

Can you hear the difference? Can anyone?

Can people hear the difference between lossy MP3 digital music files and lossless ones? Opinions differ strongly, with much obfuscation around audio cables, mastering and hi-fi componentry muddying the waters.…

Security Collapse In the HTTPS Market

Slashdot - Fri, 26/09/2014 - 4:23pm
CowboyRobot writes: HTTPS has evolved into the de facto standard for secure Web browsing. Through the certificate-based authentication protocol, Web services and Internet users first authenticate one another ("shake hands") using a TLS/SSL certificate, encrypt Web communications end-to-end, and show a padlock in the browser to signal that a communication is secure. In recent years, HTTPS has become an essential technology to protect social, political, and economic activities online. At the same time, widely reported security incidents (such as DigiNotar's breach, Apple's #gotofail, and OpenSSL's Heartbleed) have exposed systemic security vulnerabilities of HTTPS to a global audience. The Edward Snowden revelations (notably around operation BULLRUN, MUSCULAR, and the lesser-known FLYING PIG program to query certificate metadata on a dragnet scale) have driven the point home that HTTPS is both a major target of government hacking and eavesdropping, as well as an effective measure against dragnet content surveillance when Internet traffic traverses global networks. HTTPS, in short, is an absolutely critical but fundamentally flawed cybersecurity technology.

How the NSA Profits Off of Its Surveillance Technology

Slashdot - Fri, 26/09/2014 - 3:41pm
blottsie writes: The National Security Agency has been making money on the side by licensing its technology to private businesses for more than two decades. It's called the Technology Transfer Program, under which the NSA declassifies some of its technologies that it developed for previous operations, patents them, and, if they're swayed by an American company's business plan and nondisclosure agreements, rents them out. The products include tools to transcribe voice recordings in any language, a foolproof method to tell if someone's touched your phone's SIM card, or a version of email encryption that isn't available on the open market.
