This tiny generator can power wearable devices using your body heat

Many wearables have decent enough battery life, but you know what’ll make them even better? If we never have to recharge them at all. That’s why researchers have been developing small power sources that can generate electricity using body heat , including a team from the Korean Advanced Institute of Science and Technology. This particular group has designed a new light and flexible generator made out of thermoelectric (TE) substances printed on glass fabric. It’s far from being the first TE generator out there, but it’s a huge departure from the usual bulky and rigid ones. As team leader Byung Jin Cho said: This is quite a revolutionary approach to design a generator. In so doing, we were able to significantly reduce the weight of our generator, which is an essential element for wearable electronics. Body heat-absorbing generators made from inorganic materials like this have higher power output than ones made from organic substances, making them the better choice. Problem is, they’re also typically larger and more rigid. This creation addresses both issues, and the glass fabric even minimizes heat loss and maximizes output, as discussed in the paper the institute published recently. Obviously, it’ll take a long time before we see this design in real world devices, if we even see it at all. The team believes, however, that this generator doesn’t only have a future in wearables, it could also be used in cars, factories, airplanes and other vehicles.

Cherry trees blossom six years early after a trip to space

In 2008 Japanese scientists decided to take a handful of cherry tree seeds (and by “handful” we mean over 250) to space. The embryonic plants spent eight months aboard the International Space Station as part of an educational project aimed at children. When the stones returned, 14 of them were selected and planted around Japan. The saplings were expected to bloom after 10 years of maturation. Instead, four of them sprouted flowers this year — a full six years ahead of schedule. The sudden and extremely early blossoming of the trees has scientists quite confused and desperately seeking answers. Kaori Tomita-Yokotani, from the University of Tsukuba, told AFP she was stumped. “There is the possibility that exposure to stronger cosmic rays accelerated the process of sprouting and overall growth, ” she said, but also suggested that cross pollination could be the culprit. Since the project involving the seeds was not a true experiment, and more a stunt to pique the interest of children, there is no control group to compare against. In fact, there’s very little data at all for the scientists to work with. We’re betting on the cosmic rays, though. We all know what happens when humans are bombarded by them .

US Takes Out Gang That Used Zeus Malware To Steal Millions

coondoggie (973519) writes “The US Department of Justice charged nine members of a group that used Zeus malware to infect thousands of business computers and illegally siphon-off millions of dollars into over-seas bank accounts. The DoJ said an indictment was unsealed in connection with the arraignment this week at the federal courthouse in Lincoln, Neb., of two Ukrainian nationals, Yuriy Konovalenko, 31, and Yevhen Kulibaba, 36. Konovalenko and Kulibaba were recently extradited from the United Kingdom.” Read more of this story at Slashdot.

44% Of All Twitter Accounts Have Yet To Send A Tweet

A new report from Twopcharts has found that 44% of the world’s Twitter accounts have yet to send a Tweet . With approximately 974 million Twitter accounts, that’s an awful lot of dead air. As the Wall Street Journal points out, however, this could mean that people, scammers, or bots simply signed up for an account and never came back—or that there are hordes of shy people out there waiting for the moment to strike. Do you have a Twitter account you have never used? If not, why not? [ Wall Street Journal ] Read more…

Here’s how Windows 8.1 Update tries to give you the right UI on any device

The Windows 8.1 Update that introduces a bunch of interface changes to Windows 8.1 is designed to enhance the experience of mouse and keyboard users, but what about the growing number of happy touch users? About 40 percent (and increasing) of PCs available at retail have a touchscreen (compared to just 4 percent when Windows 8 launched), and for the most part, their buyers enjoy how they work. With touch interfaces a growing part of the Windows ecosystem, Microsoft didn’t want to make the touch experience worse. While many desktop users may want their systems to boot straight to the desktop, this is unlikely to be a popular option for tablet users. Touch laptop users could easily go either way. Microsoft’s goal, therefore, was to pick a sensible default based on the kind of system being used. The way the update does this is based on something called the power platform role , a setting found in the computer’s firmware specified by the manufacturer. For Windows PCs, it will typically be “desktop,” “mobile,” or “slate,” for desktops, laptops, and tablets, respectively. Read 9 remaining paragraphs | Comments

Your Clever Password Tricks Aren’t Protecting You from Today’s Hackers

Security breaches happen so often nowadays, you’re probably sick of hearing about them and all the ways you should beef up your accounts. Even if you think you’ve heard it all already, though, today’s password-cracking tools are more advanced and cut through the clever password tricks many of us use. Here’s what’s changed and what you should do about it. Read more…

Microsoft tests Live Tiles you can use without leaving the Start screen

Even Microsoft knows that Windows Live Tiles have so much potential to be a lot better, especially on touchscreen devices . In fact, a group of the company’s researchers in Asia have apparently been working on making Live Tiles interactive. As you can see in the videos after the break, the experimental tiles expand when touched, showing you its contents right on the Start screen instead of launching the app. For instance, touching the mail app automatically shows a list of your emails in an expanded view, which looks very similar to an Android widget. That’s not all, though: the team has also designed a feature called Desktop Interactive Tile, which lists the programs open on desktop mode, making them easily accessible from the modern UI. This tile can be accessed from the sidebar on desktop mode, as well, providing an easy way to launch programs or attach files to emails. Alas, Microsoft took down the project’s page after briefly showcasing it on its website, but not before ZDNet managed to grab a copy of its official description: This project features an Interactive-Tile UI system that enables users to access and manipulate Live Tiles in an interactive way with touch gestures. Interactive Tile’s UI is responsive and flexible to an app’s content and function. Users can provide quick input to the Interactive Tile on the Start screen. With a perception of Start as an entrance page, Interactive Tiles were introduced to empower the start screen with an intermediate access level to applications. As one of the company’s experimental ventures, this might not make it to production at all. But if it does, we’d love to see how it’ll play with Windows 8.1’s upcoming classic Start menu .

NSA used Heartbleed nearly from the start, report claims [Updated]

Citing two anonymous sources “familiar with the matter,” Bloomberg News reports that the National Security Agency has known about Heartbleed, the security flaw in the OpenSSL encryption software used by a majority of websites and a multitude of other pieces of Internet infrastructure, for nearly the entire lifetime of the bug—“at least two years.” The sources told Bloomberg that the NSA regularly used the flaw to collect intelligence information, including obtaining usernames and passwords from targeted sites. As Ars reported on April 9, there have been suspicions that the Heartbleed bug had been exploited prior to the disclosure of the vulnerability on April 5 . A packet capture provided to Ars by Terrence Koeman , a developer based in the Netherlands, shows malformed Transport Security Layer (TSL) Heartbeat requests that bear the hallmarks of a Heartbleed exploit. Koeman said the capture dates to November of last year. But if the NSA has been exploiting Heartbleed for “at least two years,” the agency would have needed to discover it not long after the code for the TLS Heartbeat Extension was added to OpenSSL 1.0.1, which was released on March 14, 2012. The first “beta” source code wasn’t available until January 3, 2012 . Read 2 remaining paragraphs | Comments

$250K Reward Offered In California Power Grid Attack

An anonymous reader writes “The Associated Press reports that Pacific Gas & Electric Co. has put up a $250, 000 reward for ‘information leading to an arrest and conviction in a startling attack mounted nearly a year ago on telephone lines and the power grid in Silicon Valley.’ Besides cutting power lines, the attackers also cut AT&T fiber-optic phone lines, thereby denying some people access to 911, and fired shots into a PB&E substation, knocking out 17 transformers in Silicon Valley and causing $15 million in damage. As of this post, the perpetrators are still unidentified and continue to elude the FBI. Meanwhile, the Federal Energy Regulatory Commission (FERC) on Thursday was brought before the Senate Energy Committee to explain why the FERC disseminated via insecure media a sensitive document describing where all the nation’s power grids are particularly sensitive to a physical attack. FERC responded with assurances that databases are currently being scrubbed and procedures being implemented to safeguard critical data.” Read more of this story at Slashdot.

Appeals court reverses hacker/troll “weev” conviction and sentence [Updated]

Self-portrait by Weev A federal appeals court Friday reversed and vacated the conviction and sentence of hacker and Internet troll Andrew “weev” Auernheimer. The case against Auernheimer, who has often been in solitary confinement for obtaining and disclosing personal data of about 140,000 iPad owners from a publicly available AT&T website, was seen as a test case on how far the authorities could go under the Computer Fraud and Abuse Act, the same law that federal prosecutors were invoking against Aaron Swartz. But, in the end, the Third U.S. Circuit Court of Appeals didn’t squarely address the controversial fraud law and instead said Aeurnheimer was charged in the wrong federal court.
