Science and Information / New chiral property of silicon discovered: Photonic applications

« on: July 30, 2015, 06:43:24 PM »

By encoding information in photons via their spin, 'photonic' computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make 'spintronic' computers with similar advantages. Engineers and physicists have now discovered a property of silicon that combines aspects of all of these desirable qualities.

Robots' maps of their environments can make existing object-recognition algorithms more accurate


A team of researchers specializes in SLAM, or simultaneous localization and mapping, the technique hereby mobile autonomous robots map their environments and determine their locations. Now these researchers have demonstrated how SLAM can be used to improve object-recognition systems, which will be a vital component of future robots that have to manipulate the objects around them in arbitrary ways.

Science and Information / The algorithm of writing

« on: July 30, 2015, 06:41:19 PM »

Researchers explores the promise and peril of computer-based writing assessment software.



The idea of new software is to give teachers useful diagnostic information on each writer and give them more time to address problems and assist students with things no machine can comprehend -- content, reasoning and, especially, the young writer at work.

Science and Information / Shoring up Tor: Researchers mount successful attacks against popular anonymity

« on: July 30, 2015, 06:32:56 PM »

With 2.5 million daily users, the Tor network is the world's most popular system for protecting Internet users' anonymity. Researchers have now demonstrated a vulnerability in Tor's design. They show that an adversary could infer a hidden server's location, or the source of the information reaching a given Tor user, by analyzing the traffic patterns of encrypted data passing through a single computer in the all-volunteer Tor network.

Science and Information / Energy-generating cloth could replace batteries in wearable devices

« on: March 07, 2015, 02:59:58 PM »

From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets' versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome. Scientists report the first durable, flexible cloth that harnesses human motion to generate energy. It can also self-charge batteries or supercapacitors without an external power source and make new commercial and medical applications possible.
