Do we live in a computer simulation run by our descendants? Researchers say idea can be tested Dec 10th 2012, 18:27 A decade ago, a British philosopher put forth the possibility that our universe might be a computer simulation run by our descendants. Now, physicists have come up with a potential test to see if the idea holds water. Tiny compound semiconductor transistor could challenge silicon's dominance Dec 10th 2012, 16:24 Silicon's crown is under threat: The semiconductor's days as the king of microchips for computers and smart devices could be numbered, thanks to the development of the smallest transistor ever to be built from a rival material, indium gallium arsenide. Researchers have developed the smallest indium gallium arsenide transistor ever built. Violent video games: More playing time equals more aggression Dec 10th 2012, 15:13 A new study provides the first experimental evidence that the negative effects of playing violent video games can accumulate over time. Creativity and linguistic skills important for immersion in World of Warcraft Dec 5th 2012, 15:26 The sense of immersion in role-play and computer games is sometimes viewed as dangerous, as players' strong perceptions of fictional worlds are assumed to make them lose contact with reality. On the other hand, players' immersion also implies a potential for improved learning, since it enables them to 'experience' new places and historical eras. Yet a new study from Sweden shows that immersion in online role-play games requires a lot of hard work. From rats to people: Gaming platform used to compare memory impairments of rodents and humans with epilepsy Dec 3rd 2012, 13:16 A behavioral test widely used on rodents to study spatial learning and memory, the Morris water maze (MWM), was recreated using software developed to create custom video game environments. By creating a virtual reality analogue for humans, it was possible to obtain a direct comparison between the results of studies on a rodent model of temporal lobe epilepsy (TLE), whose spatial memory performance was found to be severely impaired, and patients with TLE. Human brain, Internet, and cosmology: Similar laws at work? Nov 19th 2012, 19:05 The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new article. These mini-bots were made for walking: Cells power biological machines Nov 15th 2012, 18:37 They're soft, biocompatible, about 7 millimeters long -- and, incredibly, able to walk by themselves. Miniature "bio-bots" are making tracks in synthetic biology. The walking bio-bots demonstrate forward-engineering functional machines using only hydrogel, heart cells and a 3-D printer. The bio-bots could be customized for specific applications in medicine, energy or the environment. New tool aims to ensure software security policies reflect user needs Oct 31st 2012, 01:03 Researchers have developed a new natural language processing tool that businesses or other customers can use to ensure that software developers have a clear idea of the security policies to be incorporated into new software products. Seeing through clothing: Radiation-enabled chips could lead to low-cost security imaging systems Sep 12th 2012, 20:15 Scientists are reconfiguring existing semi-conductor computer chips and turning them into high-frequency circuits with the capability of seeing through packaging and clothing to produce an image of what is hidden underneath. The chip could be the basis of sophisticated but affordable, portable detection technology able to meet everyday security needs. 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. Turn your dreams into music Sep 10th 2012, 15:23 Computer scientists in Finland have developed a method that automatically composes music out of sleep measurements. Cybersecurity experts researching how to keep medical devices secure, communicating on hospital networks Sep 5th 2012, 15:09 What if you could shut down several emergency rooms simultaneously without leaving your own home? How about hacking a pacemaker and reprogramming it to cause a heart attack? Although these could be scenes from an espionage film, they are also some of the plausible scenarios that cybersecurity experts are working to prevent. Frankenstein programmers test a cybersecurity monster Aug 27th 2012, 21:59 To catch a thief, you have to think like one. Computer scientists are trying to stay one step ahead of cyberattackers by creating their own monster. Their monster can cloak itself as it steals and reconfigures information in a computer program. 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. Better security for web and mobile applications Jul 20th 2012, 17:57 When it comes to computer security, who checks the checker? Computer scientists have developed a new tool that could lead to increased security and enhanced performance for commonly used web and mobile applications. Called RockSalt, the clever bit of code can verify that native computer programming languages comply with a particular security policy. 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. Including ads in mobile apps poses privacy, security risks Mar 19th 2012, 15:17 Researchers have found that including ads in mobile applications poses privacy and security risks. In a recent study of 100,000 apps in the official Google Play market, researchers noticed that more than half contained so-called ad libraries. And 297 of the apps included aggressive ad libraries that were enabled to download and run code from remote servers -- which raises significant privacy and security concerns.
