A biomedical engineer is developing brain-computer interfaces based on grids of electrodes that lie beneath the skull but outside the dura mater, the protective membrane that covers the brain. His next project is to slip a thin 32-electrode grid he designed with a colleague under a macaque's skill and to train the monkey to control -- strictly by thinking about it -- a computational model of a macaque arm.

That feeling of being in, and owning, your own body is a fundamental human experience. Now, researchers have announced an important step in decoding the phenomenon. By combining techniques from cognitive science with those of virtual reality and brain imaging, scientists in Switzerland are narrowing in on the first experimental, data-driven approach to understanding self-consciousness.

When people on airplanes ask Alan Newell what he works on, he tells them "flower arrangements." He could also say "fingerprints" or "sand ripples" or "how plants grow." "Most patterns you see, including the ones on sand dunes or fish or tigers or leopards or in the laboratory – even the defects in the patterns – have many universal features," he says. Read more:

Karen Smilowitz has studied ways to optimize how freight is moved: how to reduce the distance of trucking routes, for example, or how to get companies to pool their resources and lower costs. More recently, she has taken that work and applied it to nonprofits both at a global and a local level, including finding equitable and efficient distribution of relief supplies in humanitarian logistics and improving operations for mobile delivery of asthma care.

A new study is one of the first to provide evidence of the effectiveness of exposure therapy with active duty military service members suffering from posttraumatic stress disorder (PTSD). The study shows that virtual reality exposure therapy resulted in significant reductions in PTSD symptoms after an average of seven treatment sessions. Additionally, 62 % of patients reported clinically meaningful, reliable change in PTSD symptoms. Read more:

You may have heard of virtual keyboards controlled by thought, brain-powered wheelchairs, and neuro-prosthetic limbs. But powering these machines can be downright tiring, a fact that prevents the technology from being of much use to people with disabilities, among others. Researchers in Switzerland have a solution: engineer the system so that it learns about its user, allows for periods of rest, and even multitasking. Read more:

Students in Spain have designed an innovative augmented reality system for learning to play chess. The system architecture, which combines augmented reality, computer vision and artificial intelligence, includes an application that tracks the movements of each piece, generates an audible description of each move, saves games automatically and can broadcast matches online, making it ideal for a wide range of users, including the visually impaired.

More than 50 years after the invention of the laser, scientists have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology. Read more:

Computer scientists have developed a system making it possible to steer a car with your thoughts. Using new commercially available sensors to measure brain waves -- sensors for recording electroencephalograms (EEG) -- the scientists were able to distinguish the bioelectrical wave patterns for control commands such as "left," "right," "accelerate" or "brake" in a test subject.

Mathematicians are creating their own version of the periodic table that will provide a vast directory of all the possible shapes in the universe across three, four and five dimensions, linking shapes together in the same way as the periodic table links groups of chemical elements. The three-year project should provide a resource that mathematicians, physicists and other scientists can use for calculations and research in a range of areas, including computer vision, number theory, and theoretical physics. The researchers are aiming to identify all the shapes across three, four and five dimensions that cannot be divided into other shapes. Read more:

Researchers at Toshiba are working on a way of finding clusters of like-minded bloggers and others online using "social annotations." Social annotations are the tags and keywords, the comments and feedback that users, both content creators and others associate with their content. Their three-step approach could help you home in on people in a particular area of expertise much more efficiently and reliably than simply following search engine results. The same tools might also be used in targeted marketing. Read more:
