Yet it doesn't emit or absorb light. We can only observe how it pulls and tugs on other things. But scientists at Stanford have pioneered new visualization methods, based on massive computer simulations, that allow them to see and study dark matter in ways that have never before been possible.http://video.pbs.org/video/2253154199/07/03/2012New 3D movies by Stanford Scientists reveal the universe as you've never seen it before.Science & NatureScience & NatureAstronomyAstronomyEpisodehttp://video.pbs.org/video/2239166875/We live in a world where our eyes and ears are bombarded with colors, shapes, textures and noises of all types. How exactly do our brains translate these sights and sounds into meaningful images and words? At the University of California, Berkeley, two groups of scientists are finding tantalizing new answers to this question by reconstructing what our brains see and hear.http://video.pbs.org/video/2239166875/05/30/2012Meet scientists who are learning how to reconstruct what our brains see and hear.nrScience & NatureScience & NaturePsychology & The MindPsychology & The MindTechnologyTechnologyHealthHealthScienceScienceEpisodehttp://video.pbs.org/video/2146699556/Why do our bodies wear out as we grow old? Meet Charles Mobbs, a scientist at Mount Sinai School of Medicine in New York. By trying to answer this mysterious question, he and his team have found what could be a way to do something long thought impossible: reverse kidney damage caused by diabetes.http://video.pbs.org/video/2146699556/09/27/2011Learn about a revolutionary diet that may one day help to save countless lives.nrHealth Care & IllnessesHealth Care & IllnessesNews & Public AffairsNews & Public AffairsHealthHealthScience & NatureScience & NatureTechnologyTechnologyHealthHealthScienceScienceEpisodehttp://video.pbs.org/video/2070435179/When we touch something, how do sensations from our hands get translated into perceptions by our brains? Meet two scientists who are trying to answer that question with a curious tool: rat whiskers. Just like hands are to humans, whiskers are rats' primary sensors of touch. Analyzing how whisker sensations are processed by rats' brains is helping to reveal the mysteries of our own sense of...http://video.pbs.org/video/2070435179/07/26/2011The astonishing power of rat whiskers reveals the mysteries of our own sense of touch.nrScienceScienceEpisodehttp://video.pbs.org/video/1906296021/Meet two scientists who have begun to unlock the secrets of the brain's architecture.http://video.pbs.org/video/1906296021/05/03/2011Meet two scientists who have begun to unlock the secrets of the brain's architecture.nrScience & NatureScience & NatureBiology & ChemistryBiology & ChemistryTechnologyTechnologyCommunications & MediaCommunications & MediaScienceScienceEpisode
