Mind-reading scan identifies simple thoughts - health 26 May 2011 New Scientist

    A new new brain imaging system that can identify a subject's simple thoughts may lead to clearer diagnoses for Alzheimer's disease or schizophrenia - as well as possibly paving the way for reading people's minds. Michael Greicius at Stanford University in California and colleagues used functional magnetic resonance imaging (fMRI) to identify patterns of brain activity associated with different mental states. He asked 14 volunteers to do one of four tasks: sing songs silently to themselves; recall the events of the day; count backwards in threes; or simply relax. Participants were given a 10-minute period during which they had to do this. For the rest of that time they were free to think about whatever they liked. The participants' brains were scanned for the entire 10 minutes, and the patterns of connectivity associated with each task were teased out by computer algorithms that compared scans from several volunteers doing the same task. This differs from previous experiments, in which the subjects were required to perform mental activities at specific times and the scans were then compared with brain activity when they were at rest. Greicius reasons his method encourages "natural" brain activity more like that which occurs in normal thought.

Technology Review: Blogs: arXiv blog: Highlights from the Gallery of Fluid Motion

    The best of the bunch (so far) for the 2010 American Physical Society's Gallery of Fluid Motion Each year, the Fluid Dynamics division of the American Physical Society holds a conference. This year, the meeting is in Long Beach, California, in November. One of the highlights is the impressive set of videos of fluid motion that the delegates put together. These videos have already begun to appear on the arViv in impressive numbers. Videos are an effective and increasingly popular way of publishing research. Expect to see more like this. But there are clearly better ways to make them available other than as downloads from the arXiv or as videos in a room in Long Beach. One obvious option is to make them available on streaming websites such as YouTube andVimeo. As far as I can tell, they are not available like this. Another is to create a website that showcases them in advance, to make it a global, web-based event. Many of the videos are superb. Not only could they command a bigger audience, they deserve it. If plans are afoot to make the Gallery of Fluid Motion a bigger event, then great. If not, shame! Here is my selection of the highlights this year.

Mars mapping ice buried

shared by Skeptical Debunker on 03 Mar 10 - Cached
  • The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys -- first confirmed by radar two years ago -- adds clues about how these deposits may have been left as remnants when regional ice sheets retreated. The subsurface ice deposits extend for hundreds of kilometers, or miles, in the rugged region called Deuteronilus Mensae, about halfway from the equator to the Martian north pole. Jeffrey Plaut of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and colleagues prepared a map of the region's confirmed ice for presentation at this week's 41st Lunar and Planetary Science Conference near Houston. The Shallow Radar instrument on the orbiter has obtained more than 250 observations of the study area, which is about the size of California. "We have mapped the whole area with a high density of coverage," Plaut said. "These are not isolated features. In this area, the radar is detecting thick subsurface ice in many locations." The common locations are around the bases of mesas and scarps, and confined within valleys or craters. Plaut said, "The hypothesis is the whole area was covered with an ice sheet during a different climate period, and when the climate dried out, these deposits remained only where they had been covered by a layer of debris protecting the ice from the atmosphere."

    Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble.
