A new class of carbon nanotubes could be the next-generation clean-up crew for toxic sludge and contaminated water, say researchers at Rochester Institute of Technology.Enhanced single-walled carbon nanotubes offer a more effective and sustainable approach to water treatment and remediation than the standard industry materials–silicon gels and activated carbon–according to a paper published in the March issue of Environmental Science Water: Research and Technology.RIT researchers John-David Rocha and Reginald Rogers, authors of the study, demonstrate the potential of this emerging technology to clean polluted water. Their work applies carbon nanotubes to environmental problems in a specific new way that builds on a nearly two decades of nanomaterial research. Nanotubes are more commonly associated with fuel-cell research.“This aspect is new–taking knowledge of carbon nanotubes and their properties and realizing, with new processing and characterization … [Read more...] about Reusable carbon nanotubes could be the water filter of the future, says RIT study
Carbon is the basis of life as we know it. It’s been there from the very beginning, churning and boiling in the nuclei of giant stars, before violently exploding and creating the building blocks of the world around us.This element, one of the smallest and lightest on the periodic table, has the potential to revolutionize the automotive industry. It can do this in the form of graphene, a virtually two-dimensional layer of carbon that can be used in everything from battery and solar panel manufacturing to biotechnology and filtration.The wonder materialGraphene is the strongest material ever measured. At least, that’s what Columbia University deemed in 2008.Mechanical engineering professor James Hone said, “It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.”But the stuff isn’t just sturdy; it’s also a fantastic thermal conductor at room temperature, and it’s one of the most … [Read more...] about How graphene, a nearly magic material, could revolutionize automobiles

The data drip is here. Computer security experts are worried that corporate data leaking from networks onto small mobile storage devices will worsen into a flood of stolen customer and company information.Over half of all information leaks travel to personal data storage devices such as USB drives, MP3 players and PDAs, according to recent industry surveys. These surveys suggest that portable storage devices are contributing to a staggering rise in ID theft and loss of sensitive data on the corporate level.Every 79 seconds, someone in the United States becomes a victim of such thefts. Even a single incident of data loss can cost a company millions of dollars in lost revenue, lost opportunity, lost competitive advantage and costly penalties for regulatory non-compliance, warn security experts."The cost of remediating lost data can be (US)$100 per record, so it makes economic sense to invest in data loss prevention technology," Chip Hay, vice president of marketing for security firm Code … [Read more...] about Are Data Leaks Bleeding Your Company Dry?
Apple typically has impeccable timing for its new product introductions, but that may not be the case with its new smartwatch.In a gala event last week, the company announced model and pricing details for its Apple Watch. That came just six days after questions were raised about the security of its mobile payment platform. Those questions haven't gone away, and now they're also being asked about Apple's smartwatch.Wearable computing devices like the Apple Watch are still new territory for cybercriminals, but as more of these gadgets hit the market, they'll start appearing on the radar of hackers.That could be very soon, as 2015 is expected to be a watershed year for wearables. Shipments will jump 129 percent from last year to this year, with 43.2 million units expected to enter the market, Canalys predicted.While Apple is keeping the nitty-gritty of its watch's security close to its vest, it is touting a unique skin sensor that provides a measure of security for the device."When you … [Read more...] about SPOTLIGHT ON SECURITY How Secure Is the Apple Watch?
As embedded intelligence is finding its way into ever more areas of our lives, fields ranging from autonomous driving to personalized medicine are generating huge amounts of data. But just as the flood of data is reaching massive proportions, the ability of computer chips to process it into useful information is stalling.Now, researchers at Stanford University and MIT have built a new chip to overcome this hurdle. The results are published today in the journal Nature, by lead author Max Shulaker, an assistant professor of electrical engineering and computer science at MIT. Shulaker began the work as a PhD student alongside H.-S. Philip Wong and his advisor Subhasish Mitra, professors of electrical engineering and computer science at Stanford. The team also included professors Roger Howe and Krishna Saraswat, also from Stanford.Computers today comprise different chips cobbled together. There is a chip for computing and a separate chip for data storage, and the connections between … [Read more...] about 3D Chip Combines Computing and Data Storage
A number of law enforcement groups are lobbying Congress to add provisions to a bill revamping the 1986 Electronic Communications Privacy Act (ECPA) that would require wireless carriers to archive text messages for as long as two years. There may be reasons for companies to archive messages -- but simply functioning as a record-keeping arm for law enforcement is not one of them, privacy advocates maintain.The law-enforcement groups want Congress to consider the SMS retention requirement during discussions over the revamp of the 1986 law, a version of which cleared the Senate Judiciary committee two weeks ago."It doesn't belong in reform of the privacy act," Chris Calabrese, legislative counsel for the American Civil Liberties Union in Washington, D.C. told TechNewsWorld. "The proposal creates enormous privacy problems for ordinary citizens. These records aren't just open to law enforcement. They can be open to civil litigants and divorce lawyers, and they can be leaked. Once you start … [Read more...] about SPOTLIGHT ON SECURITY Cops Seek Law Requiring 2-Year SMS Storage
Cloud security skeptics were given yet another reason to doubt the fortitude of online storage when the strange tale of Mat Honan emerged earlier this month. Through the clever use of social engineering, a hacker was able to wreak havoc on the Wired journalist's digital life.Apparently, the hacker talked Amazon tech support into providing the last four digits of Honan's credit card number. This information was then used to fool Apple into thinking the hacker was Honan and issuing a temporary password for Honan's email account.The hacker used this information to ultimately delete Honan's Gmail account, permanently reset his AppleID and Twitter passwords, and remotely wipe his iPhone, iPad and MacBook.Apple and Amazon closed the specific security holes that enabled this attack after news of Honan's problem hit the headlines. But the question remains: How secure is information in the cloud, really?More than 80 percent of 4,000 business and IT managers worldwide surveyed by the Ponemon … [Read more...] about How Secure Is the Cloud, Really?
Posting its best overall quarter since merging with Compaq more than a year ago, Hewlett-Packard outpaced earnings and revenue estimates in the third quarter and said all five of its business segments operated in the black.The company said it brought in revenue of US$19.85 billion during the quarter ended October 31st, up from $18.05 billion a year ago. Profit more than doubled in the quarter to $862 million."By any measure, we hit our stride and demonstrated what the merger was all about," said HP CEO Carly Fiorina, who is credited with being the architect of the controversial $19 billion merger with Compaq. "We delivered on our commitments. We exceeded our integration and cost saving goals ahead of schedule."HP did not provide an outlook for 2004. However, it did say revenue will be down slightly quarter-to-quarter in the last three months of the year, although it still should be above analysts' estimate of $19 billion.In a conference call, Fiorina said HP is laying out its business … [Read more...] about HP Beats Street as All Units Turn Profit
