BrainBrowser - 0 views

  •  
    BrainBrowser is web-based, 3D visualization tool for neuroimaging. Using web-standard technologies, such as WebGL and HTML5, it allows for real time manipulation and analysis of 3D neuroimaging data whether it be precalculated maps, such as the MACACC data set (Mapping Anatomical Correlations Across Cerebral Cortex), or models provided by the user in MNI object format and data in one of the many currently supported formats (Minc, Nifti, object files, plain text).

Trafton Drew: Why Even Radiologists Can Miss A Gorilla Hiding In Plain Sight - 0 views

  •  
    "He then asked a bunch of radiologists to review the slides of lungs for cancerous nodules. He wanted to see if they would notice a gorilla the size of a matchbook glaring angrily at them from inside the slide. But they didn't: 83 percent of the radiologists missed it, Drew says. This wasn't because the eyes of the radiologists didn't happen to fall on the large, angry gorilla. Instead, the problem was in the way their brains had framed what they were doing. They were looking for cancer nodules, not gorillas. "They look right at it, but because they're not looking for a gorilla, they don't see that it's a gorilla," Drew says. In other words, what we're thinking about - what we're focused on - filters the world around us so aggressively that it literally shapes what we see"

Why some Americans believe Obama is a Muslim - 0 views

    "ScienceDaily (Aug. 31, 2010) - There's something beyond plain old ignorance that motivates Americans to believe President Obama is a Muslim, according to a first-of-its-kind study of smear campaigns led by a Michigan State University psychologist."

Scientists are only two years from developing a cure for breast cancer? : Respectful In... - 0 views

  •  
    It's just plain silly to make claims like this about a basic science paper given that, as I have discussed before, it often takes decades for basic science observations to wend their way through that long strange trip to becoming actual therapies used by clinicians. The life cycle of translational research is long, and efforts to speed it up have only met with mixed success.

Graphene may reveal the grain of space-time - physics-math - 13 May 2011 - New Scientist - 1 views

    COULD the structure of space and time be sketched out inside a cousin of plain old pencil lead? The atomic grid of graphene may mimic a lattice underlying reality, two physicists have claimed, an idea that could explain the curious spin of the electron. Graphene is an atom-thick layer of carbon in a hexagonal formation. Depending on its position in this grid, an electron can adopt either of two quantum states - a property called pseudospin which is mathematically akin to the intrinsic spin of an electron. Most physicists do not think it is true spin, but Chris Regan at the University of California, Los Angeles, disagrees. He cites work with carbon nanotubes (rolled up sheets of graphene) in the late 1990s, in which electrons were found to be reluctant to bounce back off these obstacles. Regan and his colleague Matthew Mecklenburg say this can be explained if a tricky change in spin is required to reverse direction. Their quantum model of graphene backs that up. The spin arises from the way electrons hop between atoms in graphene's lattice, says Regan. So how about the electron's intrinsic spin? It cannot be a rotation in the ordinary sense, as electrons are point particles with no radius and no innards. Instead, like pseudospin, it might come from a lattice pattern in space-time itself, says Regan. This echoes some attempts to unify quantum mechanics with gravity in which space-time is built out of tiny pieces or fundamental networks (Physical Review Letters, vol 106, p 116803). Sergei Sharapov of the National Academy of Sciences of Ukraine in Kiev says that the work provides an interesting angle on how electrons and other particles acquire spin, but he is doubtful how far the analogy can be pushed. Regan admits that moving from the flatland world of graphene to higher-dimensional space is tricky. "It will be interesting to see if there are other lattices that give emergent spin," he says.
