The brain appears to be wired in a rectangular 3D grid structure, suggests a new brain imaging study funded by the National Institutes of Health. "Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables - folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric," explained Van Wedeen, M.D., of Massachusetts General Hospital (MGH), A.A. Martinos Center for Biomedical Imaging and the Harvard Medical School.

During the GNSS Vulnerability 2012 event at the UK's National Physical Laboratory on Wednesday, experts discussed the threat posed by a growing number of GPS jamming and spoofing devices. The increasing popularity of the jammers is troubling, according to conference organizer Bob Cockshott, because even low-power GPS jammers pose a significant threat to cell phone systems, parts of the electrical grid, and the safety of drivers.
