The size of brain areas in the striatum, a region deep within the cerebral cortex, has a measurable effect on specifc types of video game performance, ten neuroscientists have found. They conducted an experiment in which each subject received 20 hours of training to play a video game specifically created for research purposes. Some of the players were told to focus exclusively on running up a high score, while others were told to shift their prio... More

Young people (8-18) devote an average of 7 hours and 38 minutes (7:38) to using entertainment media across a typical day (more than 53 hours a week), increasing by one hour and seventeen minutes a day over the past five years, according to a new study, Generation M2: Media in the Lives of 8- to 18-Year-Olds, designed and analyzed by the Kaiser Family Foundation and Stanford University researchers.The increase in media use is driven in large part b...

Evidence for a regular triangular grid of neurons in the entorhinal cortex of the brain that helps us navigate has been found by University College London scientists.They used functional magnetic resonance imaging (fMRI) to monitor neural activity to detect populations of cells that seemed to fire as the volunteers played a virtual reality game in which they had to replace an object in the location where they originally found it.

University of California, San Diego researchers and colleagues have genetically engineered bacteria that fluoresce in synchronised bursts.Controlling synchrony between cells might lead to implants made of engineered cells that act as a periodic drug delivery devices, or provide new insights into sleep, learning and brain diseases like Parkinson's and Alzheimer's, which are thought to occur when synchrony between neurons is abnormal.

Scientists at the Stanford University School of Medicine have identified a molecule, DNMT1, that helps stem cells know whether to self-renew to create more stem cells, or to differentiate into specialized, non-dividing adult skin cells. It's important because too much self-renewal can lead to cancer, and too little can inhibit wound healing. (Source: http://www.physorg.com/news183144167.html)

Transplanted neurons grown from embryonic stem cells can be directed not only to become specific brain cells, but to link correctly into the brains of young animals, a team of neuroscientists led by James Weimann of Stanford Medical School has found. For example, cells transplanted into the visual cortex reached two deep brain structures called the superior colliculus and the pons, but not to the spinal cord; cells placed into the motor area of t...

(Helmholtz Association of German Research Centres) Researchers from Helmholtz-Zentrum Berlin and the French research facility CNRS, south of Paris, are using electric fields to manipulate the property of electrons known as "spin" to store data permanently. This principle could not only improve random access memory in computers, it could also revolutionize the next generation of electronic devices.

A research team from Northeastern University has developed a new nanolens that can beat the diffraction limit to achieve so-called super-resolution imaging, better than can be achieved by current technology. The nanolens is made from arrays of nanowires also called as metamaterials -- manufactured materials not found in nature -- and has superior imaging capabilities compared to current imaging technologies.

"If we can build more direct connections between bioengineering and the fields of ecology and basic organismal sciences--converging at a place you might call "econeering"--we could together meet urgent bioengineering needs more quickly, and direct resources toward basic science discovery," say MIT scientists Edward Boyden and Brian Y. Chow, who are using econeering to pioneer a new area--the use of natural reagents to mediate control of biological... More

Scientists at the Max Planck Institute for Dynamics and Self-Organization have developed a walking robot that can flexibly and autonomously switch between different gaits, modeled on human-animal neural circuits called "central pattern generators" (CPG): a simple network with just a few sensors can create very diverse movement patterns. The secret of its functioning lies in "chaos control": If uncontrolled, the CPG produces a chaotic activity pat... More
