Even as videogames come under scrutiny for potential harmful impacts, researchers and developers are touting digital games for positive effects on health, learning and other social goals. http://phys.org/news282728559.html Technology Sun, 17 Mar 2013 08:42:51 EST news282728559 By achieving the synthesis of a novel nanohybrid structure by means of the pulsed laser ablation (PLA) technique, Professor My Ali El Khakani and his team paved the way for a new generation of optoelectronic materials. The combination of carbon nanotubes and lead sulfide (PbS) nanoparticles was performed using an effective and relatively simple process that offers considerable latitude for creating other nanohybrids for a variety of applications. The INRS Énergie Matériaux Télécommunications Research Centre researcher's work, published in the renowned journal Advanced Materials, presents very promising prospects for the development of third-generation solar devices, fast photodetectors, and optoelectronic switches. http://phys.org/news278340784.html Nanotechnology Fri, 25 Jan 2013 12:53:15 EST news278340784 A couple of years ago, Hesham Rakha misjudged a yellow traffic light and entered an intersection just as the light turned red.

In particular, if many cars join to form long convoys. On May 14 and 15, 2011, ten research groups will meet in Holland for the first time and test convoy driving without drivers on an about 6 km long motorway section in the Grand Cooperative Driving Challenge. KIT researchers involved in the AnnieWAY team will take part. http://phys.org/news224335620.html Technology Wed, 11 May 2011 12:27:40 EST news224335620 The team, working with Sichuan University in Chengdu, China, investigated eye movements in Chinese and British people to further understanding of the brain mechanisms that control them and how they compare between different human populations. They found that a type of eye movement, that is rare in British people, is much more common in Chinese people, suggesting that there could be subtle differences in brain function between different populations. http://phys.org/news220184335.html Medicine & Health Thu, 24 Mar 2011 11:19:10 EST news220184335 (PhysOrg.com) -- People fluent in sign language may simultaneously keep words and signs in their minds as they read, according to an international team of researchers. http://phys.org/news220007032.html Medicine & Health Tue, 22 Mar 2011 10:04:30 EST news220007032 Does experience give seniors an edge in reacting to sudden change or are younger people quicker to respond? A new study from Concordia University shows that when a routine task is interrupted by an unexpected event, younger adults are faster at responding.
