Molybdenum disulfide sheets -- which are "sandwiches" of one molybdenum atom between two sulfur atoms -- may improve rechargeable lithium-ion batteries, according to the latest research from Gurpreet Singh, assistant professor of mechanical and nuclear engineering. Credit: Kansas State University The key to better cellphones and other rechargeable electronics may be in tiny "sandwiches" made of nanosheets, according to mechanical engineering research from Kansas State University. Gurpreet Singh, assistant professor of mechanical and nuclear engineering, and his research team are improving rechargeable lithium-ion batteries. The team has focused on the lithium cycling of molybdenum disulfide, or MoS2, sheets, which Singh...

No browsers are safe as proved yesterday at Pwn2Own, but crashing one of them with just one line of special code is slightly different. A developer has discovered a hack in Google Chrome which can crash the Chrome tab on a Mac PC. The code is a 13 character special string which appears to be written in Assyrian script *break* Matt C has reported the bug to Google, who have marked the report as duplicate. This means that Google are aware of the problem and are reportedly working on it.

The world’s first fully digital radio transmitter has been developed by Cambridge Consultants, paving the way for 5G high-speed broadband for mobile devices. Unlike software-defined radio (SDR), the breakthrough – named Pizzicato – is not a mixture of analogue and digital components but is completely digital, which can enable new ways of using the radio spectrum intelligently. When transmitting data, only low frequency signals of 1GHz or lower propagate well over distance or through walls, so they are in great demand. Expanding to make use of frequencies of 10GHz and beyond will require techniques such as meshing and beamforming...

A Chinese immigrant who stole trade secrets from the Chicago Merc worth an estimated $50 million was spared prison Tuesday by a federal judge who cited his otherwise “exemplary life.” Chunlai Yang, 50, of Libertyville, was instead sentenced to just four years probation for stealing software that underpinned the CME Group’s Globex trading platform. Yang, who worked as a high-ranking programmer for the Merc from 2000 until his arrest in 2011, pleaded guilty in 2012 to the theft, admitting he was trying to create a similar product in China when he illegally downloaded more than 10,000 computer source code files....

Eventually, the conventional ways of manufacturing microprocessors, graphics chips, and other silicon components will run out of steam. According to Intel researchers speaking at the ISSCC conference this week, however, we still have headroom for a few more years. Intel plans to present several papers this week at the International Solid-State Circuits Conference in San Francisco, one of the key academic conferences for papers on chip design. Intel senior fellow Mark Bohr will also appear on a panel Monday night to discuss the challenges of moving from today's 14nm chips to the 10nm manufacturing node and beyond.

This is an update to article written a few years ago. Everybody knows that retail and institutional investors are usually late to a trade. When they decide to buy, the wise guys are distributing or selling their shares to them and locking in their gains. When they sell, the wise guys are accumulating or buying their shares from them, again locking in their gains. How do the wise guys pull it off? The answer lies in the combination of reflexive human behavior and the use of high frequency, algorithmic (HFA) trading. With the advance of computer trading on a massive...

Computers have as much consciousness as cars or concrete. This will not change. They’re machines. They can be programmed to follow directions and calculate certain kinds of solutions within those directed parameters. That’s it. That’s the beginning and end of the story. Why do some technocrats believe computers will gain actual consciousness? They think a) the brain is a machine that expresses consciousness via information processing, and b) information processing is all the consciousness there is. To sum up, technocrats are high-IQ idiots. You can assemble all the information in the world and cross-reference it 100 billion different ways; you...

KAOHSIUNG, Taiwan, Jan. 19 (UPI) -- A Taiwanese man who was on a three-day computer gaming binge died in an Internet cafe and went unnoticed for hours, the second such death in the area in less than a month. The man, identified as Hsieh, went into the Internet cafe on Jan. 6 and was found motionless on a table on Jan. 8. Investigators said the man had a heart attack. His death went unnoticed for several hours as gamers continued around him. "The CCTV footage from the Internet cafe showed that he had a small struggle before he collapsed motionless,"...

Researchers at Check Point have discovered a serious security vulnerability affecting at least 12 million leading-brand home and SME routers that appears to have gone unnoticed for over a decade. Dubbed the ’Misfortune Cookie’ flaw, the firm plans to give a detailed account of the issue at a forthcoming security conference but in the meantime it’s important to stress that no real-world attacks using it have yet been detected. That said, an attacker exploiting the flaw would be able to monitor all data travelling through a gateway such as files, emails and logins and have the power to infect connected...

After about 10 years with gmail.com, I've decides to migrate to a new email address. I figure it will take few months, and will insert a forward rule in my current gmail account. I'd like to find another free provider if possible. I don't mind using a service that wraps advertising around received message, but I don't want to use a provide that wraps around sent messages. I know about reagan.com but they charge. I know they advertise explicitly that they do not browse messages for social engineering, advertising ... etc. That attracts me and if I do choose a...

A relatively long-standing vulnerability in OS X has been uncovered by a Swedish hacker, Emil Kvarnhammar, who has dubbed it “rootpipe” by the so-far undisclosed method in which it can be used to take control of your Mac. In this vulnerability, a flaw allows a hacker to gain administrative access of a system without supplying a password, and then be able to interact with your Mac as an administrator. In an interview with MacWorld, Kvarnhammar describes this bug as having been present in OS X 10.8.5, but he was not able to replicate it in 10.9; however, Apple has shuffled...

The new hybrid device might not need humans at all. In college, it wasn’t rare to hear a verbal battle regarding artificial intelligence erupt between my friends studying neuroscience and my friends studying computer science. One rather outrageous fellow would mention the possibility of a computer takeover, and off they went. The neuroscience-savvy would awe at the potential of such hybrid technology as the CS majors argued we have nothing to fear, as computers will always need a programmer to tell them what to do. Today’s news brings us to the Neural Turing Machine, a computer that will combine the...

A former CBS News reporter who quit the network over claims it kills stories that put President Obama in a bad light says she was spied on by a “government-related entity” that planted classified documents on her computer. In her new memoir, Sharyl Attkisson says a source who arranged to have her laptop checked for spyware in 2013 was “shocked” and “flabbergasted” at what the analysis revealed. “This is outrageous. Worse than anything Nixon ever did. I wouldn’t have believed something like this could happen in the United States of America,” Attkisson quotes the source saying. She speculates that the...

WASHINGTON (Reuters) - A company that performs background checks for the U.S. Department of Homeland Security said on Wednesday it was the victim of a cyber attack, adding in a statement that "it has all the markings of a state-sponsored attack." The computer breach at Falls Church, Virginia-based US Investigations Services (USIS) probably involved the theft of personal information about DHS employees, according to the Washington Post, which first reported the story. DHS has suspended all work with the company amid an investigation by the FBI, the Post reported. A U.S. government official confirmed to Reuters that the FBI is...
