Submission + - Stretchable Conducting Fiber Provides Super Hero Capabilities->

schwit1 writes: The list of potential applications for a new electrically conducting fiber-artificial muscles, exoskeletons and morphing aircraft-sounds like something out of science fiction or a comic book. With a list like that, it's got to be a pretty special fiber... and it is. The fiber, made from sheets of carbon nanotubes wrapped around a rubber core, can be stretched to 14 times its original length and actually increase its electrical conductivity while being stretched, without losing any of its resistance.

Submission + - How Experts Stay Safe Online And What Non-Experts Can Learn From Them

An anonymous reader writes: Google researchers have asked 231 security experts and 294 web-users who aren’t security experts about their security best practices, and the list of top ones for each group differs considerably. Experts recognize the benefits of updates, while non-experts are concerned about the potential risks of software updates. Non-experts are less likely to use password managers: some find them difficult to use, some don't realize how helpful they can be, and others are simply reluctant to (as they see it) "write" passwords down. Another interesting thing to point out is that non-experts love and use antivirus software.

Submission + - President of Finland Turns To Radio Phone-in For Parsnip Advice

jones_supa writes: Listeners to a Finnish radio phone-in show on Wednesday may have thought they heard a familiar voice when one caller rang to ask for advice about his parsnips. It was "Sauli from Naantali". So began what seemed like a casual call to Yle Radio Suomi's weekly nature discussion show, where experts offer up tips and thoughts on everything from the beauty of countryside to the best way to cultivate vegetables in the garden. The person on the line was actually President of Finland, Sauli Niinistö. The keen nature lover had two questions for the experts — one regarding parsnips, the other about the wild flower sneezewort. In the recording of the show we can hear the presenters answering them with cool-headedness, only occasionally letting out giggles of surprise.

Submission + - Hackers seize control of car using DAB radio signals->

An anonymous reader writes: Cars can be hacked remotely using radio signals sent to inbuilt infotainment systems, researchers have warned. According to security experts NCC Group, the hacking technique can be used against several vehicles at one time and can be created easily using “off-the-shelf components” [http://www.bbc.co.uk/news/technology-33622298]. The Manchester-based company explained that the hacking method works by sending data across DAB, or digital audio broadcasting, radio signals. The signals could be used to remotely access critical systems such as a vehicle’s steering and braking functionality.

is there room on the 23andMe profile page for a complete set of fingerprints, a SSN, a DOB, home address, mother's maiden name, blood type and group, mug shot, all your credit card numbers, expiration dates and security codes, website logins and passwords, religious affiliations, and bust/penis size and circumcision status?!?

No, silly, that stuff goes on Facebook.

The real problem is the very existence of 23andme and its ilk, aggravated by the fact that it belongs to Ancestry.com, a corporate branch of one particularly agressive missionary church.

Exxxzzzaaaaaccccttttllllyyyy!!! A proper test on "St-36" would include stabbing of nearby non-"St-36" points. Randomly select which stab to electrify. Vary over time. Cross-correlate the measured response series to each of the stabs' selection series. Repeat until p=.05. The experiment may have to be prematurely terminated if the supply of rat chow (or grant money) is extinguished.

Submission + - Your body, the battery: Powering gadgets from human "Biofuel"

An anonymous reader writes: This article takes a look at the future of electronic devices powered by the human body. From tiny electric voltage in mammal ears called the endocochlear potential, to body heat, and muscle motion, there are a number of exciting new areas of energy research being explored. Ars reports: "Staying alive guzzles energy. In order to keep us ticking, our bodies need to burn between 2,000 and 2,500 calories per day, which is conveniently enough to power a modestly used smart phone. So if just a fraction of that energy could be siphoned, our bodies could in theory be used to run any number of electronic devices, from medical implants to electronic contact lenses—all without a battery in sight. Recently, researchers have taken important strides toward unlocking this electric potential."

Submission + - New molecular transistor can control single electrons->

Eloking writes: Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics.

The BBC is reporting on results that are several years old. There has been much work recently on the topic. It seems that without SHARP1 and SHARP2 you have higher IGF-2 levels, are better at memory consolidation, but more prone to schizophrenia. Kinda gives "crazy smart" a whole new meaning...

Submission + - More supermassive black holes than we thought!->

LeadSongDog writes: The Royal Astronomical Society advises that, the Nuclear Spectroscopic Telescope Array (NuSTAR) has confirmet the long suspected: many SMBHs are obscured by a surrounding cloud. Observing nine known black holes at X-ray energies not previously visible, they found that five of the nine were emitting much more energetic X-rays than had been known. They so conclude that the SMBHs are much more common than had been known.
