Are social networking Internet sites a factor in psychotic symptoms? Nov 20th 2012, 17:20 Internet communication is exploding -- and so is the possibility of a related psychopathology called Internet addiction. Now a researcher says that a review of several case studies from his own practice shows a direct connection between psychotic episodes and participation in certain online social networking sites. Finding rainbows on the nanoscale may lead to better solar cells and LED-displays Nov 20th 2012, 13:50 New research may lead to improved solar cells and LED-displays. Researchers have demonstrated in detail how to separate colors and create 'rainbows' using nanoscale structures on a metal surface. Leap forward in brain-controlled computer cursors: New algorithm greatly improves speed and accuracy Nov 18th 2012, 19:15 Researchers have designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts. The algorithm's speed, accuracy and natural movement approach those of a real arm, and the system avoids the long-term performance degradations of earlier technologies. Important progress for spintronics: Spin amplifier works at room temperature Nov 16th 2012, 17:46 A fundamental cornerstone for spintronics that has been missing up until now has been constructed by a team of physicists. A newly developed spin amplifier can be used at room temperature. Measuring 'the cloud: 'Performance could be better Nov 16th 2012, 13:56 Storing information "in the Cloud" is rapidly gaining in popularity. Yet just how do these services really work? Researchers have completed the first comprehensive analysis of Dropbox, a popular service that already has 100 million users. One shortcoming of this service is that performance is greatly dependent on the physical distance to the Dropbox servers. Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator Nov 15th 2012, 19:15 Using tiny radiation pressure forces, physicists converted an optical field, or signal, from one color to another, aided by a "dark mode." The conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations. First noiseless single photon amplifier Nov 12th 2012, 15:10 Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The next step will be to build additional quantum teleportation into the experiment, which will make the noiseless amplifier more directly useful for long-distance communication. Experimental interplanetary Internet used to test robot from International Space Station Nov 8th 2012, 20:18 NASA and the European Space Agency (ESA) successfully have used an experimental version of interplanetary Internet to control an educational rover from the International Space Station. The experiment used NASA's Disruption Tolerant Networking (DTN) protocol to transmit messages and demonstrate technology that one day may enable Internet-like communications with space vehicles and support habitats or infrastructure on another planet. Data storage: How magnetic recording heats up Nov 8th 2012, 19:08 Characterization of the thermal processes involved in heat-assisted magnetic recording paves the way for commercial devices. Dealing with power outages more efficiently Nov 7th 2012, 13:56 When there is a power failure, the utility companies, public officials and emergency services must work together quickly. Researchers have created a new planning software product that enables all participants to be better prepared for emergency situations. Cancer data in the 'cloud' could lead to more effective treatment Nov 6th 2012, 19:35 Researchers are using cloud technology to collect information from thousands of cancer cell samples. The goal is to help doctors better predict how a patient's illness will progress and what type of treatment will be most effective. New computational method for timing the tree of life Nov 6th 2012, 15:20 A scientist has developed a new method for calculating species divergence, delivering accurate results at 1,000 times the speed of conventional techniques. Privacy vs. protection: Study considers how to manage epidemics in information blackouts Nov 1st 2012, 21:19 When foot-and-mouth disease swept through the British countryside in early 2001, more than 10 million sheep, cattle and pigs were slaughtered to control the disease. Despite the devastation, the disease was contained within ten months in part owing to the availability in that country of finely detailed farm data, which enabled mathematical modelers to make accurate predictions about the spread of the disease and suggest optimal ways of managing it. Peer review option proposed for biodiversity data Oct 25th 2012, 15:01 Data publishers should have the option of submitting their biodiversity datasets for peer review, according to a new discussion paper. Invisible QR codes tackle counterfeit bank notes Sep 12th 2012, 00:01 An invisible quick response (QR) code has been created by researchers in an attempt to increase security on printed documents and reduce the possibility of counterfeiting, a problem which costs governments and private industries billions of pounds each year. Speedy ions could add zip to quantum computers Aug 13th 2012, 21:33 Take that, sports cars! Physicists can accelerate their beryllium ions from zero to 100 miles per hour and stop them in just a few microseconds. The researchers think their zippy ions may be useful in future quantum computers. Data storage: Memory that does it all Aug 2nd 2012, 19:03 Using the correct annealing temperature is key to making fast, non-volatile computer memory. Social responsibility: Monitoring children's social media usage is important, but so is allowing their mistakes Jul 11th 2012, 15:14 How parents can prevent cyberbullying and protect personal privacy on social media -- both through their child's social media account and their own account. Hard drives: A bit of progress May 10th 2012, 13:56 A modified approach to fabrication of magnetic memory elements may lead to a new generation of stable, ultra-high-capacity hard drives. Android vulnerability debugged Apr 12th 2012, 14:54 Researchers have discovered and neutralized a serious vulnerability present in all versions of Android, the popular operating system developed by Google specifically for smartphones and tablet computers. The vulnerability could have been easily exploited by malicious software applications, with the effect of making devices based on Google's operating system currently on the market completely unusable.
