Navy Creates Fuel From Seawater

New submitter lashicd sends news that the U.S. Naval Research Laboratory has announced a successful proof-of-concept demonstration of converting seawater to liquid hydrocarbon fuel. They used seawater to provide fuel for a small replica plan running a two-stroke internal combustion engine. “Using an innovative and proprietary NRL electrolytic cation exchange module (E-CEM), both dissolved and bound CO2 are removed from seawater at 92 percent efficiency by re-equilibrating carbonate and bicarbonate to CO2 and simultaneously producing H2. The gases are then converted to liquid hydrocarbons by a metal catalyst in a reactor system. … NRL has made significant advances in the development of a gas-to-liquids (GTL) synthesis process to convert CO2 and H2 from seawater to a fuel-like fraction of C9-C16 molecules. In the first patented step, an iron-based catalyst has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins). These value-added hydrocarbons from this process serve as building blocks for the production of industrial chemicals and designer fuels.” Read more of this story at Slashdot.

LAPD officers monkey-wrenched cop-monitoring gear in patrol cars

Cliff The Los Angeles Police Commission is investigating how half of the recording antennas in the Southeast Division went missing, seemingly as a way to evade new self-monitoring procedures that the Los Angeles Police Department imposed last year. The antennas, which are mounted onto individual patrol cars, receive recorded audio captured from an officer’s belt-worn transmitter. The transmitter is designed to capture an officer’s voice and transmit the recording to the car itself for storage. The voice recorders are part of a video camera system that is mounted in a front-facing camera on the patrol car. Both elements are activated any time the car’s emergency lights and sirens are turned on, but they can also be activated manually. According to the Los Angeles Times , an LAPD investigation determined that around half of the 80 patrol cars in one South LA division were missing antennas as of last summer, and an additional 10 antennas were unaccounted for. Citing a police source, the newspaper said that removing the antennas can reduce the range of the voice transmitters by as much as a third of the normal operating distance.

Intrepid Hackers Use Chinese Takeout Menu to Access a Major Oil Company

With big companies taking every precaution against malware they can possibly think of, it’s getting increasingly difficult for hackers to wedge their way in. So instead of going after the highly secure company employee accounts themselves, hackers are going after what those employees hold most dear— Chinese takeout . Read more…

Samsung Claims Breakthrough In Graphene Chip Design

jfruh (300774) writes “Graphene, a carbon-based crystalline lattice that is extremely strong, lightweight, and an excellent conductor of electricity and heat, is coveted as a potential base for semiconductor chip design, and Samsung, working with the Sungkyungkwan University School of Advanced Materials Science and Engineering, has claimed a big jump towards that goal. With IBM also making progress in this realm, the days of silicon could actually be numbered.” Read more of this story at Slashdot.

Critical crypto bug exposes Yahoo Mail passwords Russian roulette-style

Mascamon at lb.wikipedia Lest readers think “catastrophic” is too exaggerated a description for the critical defect affecting an estimated two-thirds of the Internet’s Web servers , consider this: at the moment this article was being prepared, the so-called Heartbleed bug was exposing end-user passwords, the contents of confidential e-mails, and other sensitive data belonging to Yahoo Mail and almost certainly countless other services. The two-year-old bug is the result of a mundane coding error in OpenSSL , the world’s most popular code library for implementing HTTPS encryption in websites, e-mail servers, and applications. The result of a missing bounds check in the source code, Heartbleed allows attackers to recover large chunks of private computer memory that handle OpenSSL processes. The leak is the digital equivalent of a grab bag that hackers can blindly reach into over and over simply by sending a series of commands to vulnerable servers. The returned contents could include something as banal as a time stamp, or it could return far more valuable assets such as authentication credentials or even the private key at the heart of a website’s entire cryptographic certificate. Underscoring the urgency of the problem, a conservatively estimated two-thirds of the Internet’s Web servers use OpenSSL to cryptographically prove their legitimacy and to protect passwords and other sensitive data from eavesdropping. Many more e-mail servers and end-user computers rely on OpenSSL to encrypt passwords, e-mail, instant messages, and other sensitive data. OpenSSL developers have released version 1.0.1g that readers should install immediately on any vulnerable machines they maintain. But given the stakes and the time it takes to update millions of servers, the risks remain high. Read 6 remaining paragraphs | Comments

Online Skim Reading Is Taking Over the Human Brain

Hugh Pickens DOT Com (2995471) writes “Michael S. Rosenwald reports in the Washington Post that, according to cognitive neuroscientists, humans seem to be developing digital brains with new circuits for skimming through the torrent of information online at the expense of traditional deep reading circuitry… Maryanne Wolf, one of the world’s foremost experts on the study of reading, was startled last year to discover her brain was apparently adapting, too. After a day of scrolling through the Web and hundreds of e-mails, she sat down one evening to read Hermann Hesse’s challenging novel The Glass Bead Game. ‘I’m not kidding: I couldn’t do it, ‘ says Wolf. ‘It was torture getting through the first page. I couldn’t force myself to slow down so that I wasn’t skimming, picking out key words, organizing my eye movements to generate the most information at the highest speed. I was so disgusted with myself.’ The brain was not designed for reading and there are no genes for reading like there are for language or vision. … Before the Internet, the brain read mostly in linear ways — one page led to the next page, and so on. The Internet is different. With so much information, hyperlinked text, videos alongside words and interactivity everywhere, our brains form shortcuts to deal with it all — scanning, searching for key words, scrolling up and down quickly. This is nonlinear reading, and it has been documented in academic studies. … Some researchers believe that for many people, this style of reading is beginning to invade our ability to deal with other mediums. ‘We’re spending so much time touching, pushing, linking, scrolling and jumping through text that when we sit down with a novel, your daily habits of jumping, clicking, linking is just ingrained in you, ‘ says Andrew Dillon.” Read more of this story at Slashdot.

Intel expands 10Gbps “Thunderbolt Ethernet” capability to Windows

Thunderbolt 2 is picking up another feature. Chris Foresman If standard gigabit Ethernet isn’t cutting it for you, Intel will soon give you another option: this week at the National Association of Broadcasters (NAB) show in Las Vegas, the company announced a new feature called ” Thunderbolt Networking ” that will soon be available to all PCs with Thunderbolt 2 controllers. The feature, which will be enabled by an upcoming Windows driver update, will “emulat[e] an Ethernet connection environment” and provide a 10Gbps two-way link between two computers connected with a Thunderbolt cable. Since you’ll need to connect the two computers directly to each other, this solution obviously won’t scale as well as real 10Gbps networking equipment. But for now, that hardware remains relatively uncommon and expensive—well outside the price range of individuals and smaller businesses. Thunderbolt Networking is apparently not being enabled for older computers with first-generation Thunderbolt controllers. While the feature will be new to the Windows operating system, the ability to network two Thunderbolt Macs together was introduced back in Mavericks. It doesn’t appear to require Thunderbolt 2 on that platform, though as we experienced , configuring a Thunderbolt Bridge can make for fast but occasionally choppy transfer speeds. That test connected one Thunderbolt 2 Mac to an older model with a first-generation Thunderbolt controller, though—it’s possible that connecting Thunderbolt 2 Macs to each other results in a more stable connection however. This new Windows driver update will enable any two Thunderbolt 2 PCs and Macs to be connected, though to date the Windows laptops, workstations, and motherboards with integrated Thunderbolt 2 controllers have been few and far between.
