Optic flow: A step in the right direction

The way objects appear to stream by us as we move through the world is a phenomenon called optic flow. Think of the street signs and storefronts that sail across the car windshield as we drive. That's optic flow in action. Brown University cognitive scientists have now shown, in research to be featured on the cover of Current Biology, that optic flow plays a critical role in continuously recalibrating our steps as we walk.

1. Motile Cilia go with the flow
   04-22-2007 · EurekAlert!
   Cilia, tiny hair-like structures that propel mucus out of airways, have to agree on the direction of the fluid flow to get things moving. Researchers at the Salk Institute for Biological Studies discovered a novel two-step mechanism that ensures that all cilia beat in unison.

   Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers at Rensselaer Polytechnic Institute and the University of Akron have taken one sticky step in the right direction, creating synthetic "gecko tape" with four times the sticking power of the real thing.

3. Trans fat ban: Watch saturated fats and calories too
   12-22-2006 · EurekAlert!
   The New York City trans fat ban is a step in the right direction, but the regulation that requires some restaurants to display calories as prominently as price is just as important. Also missing in the discussion? Replacing trans fat will saturated fat would be problematic.

4. Nanoparticle Assembly Enters The Fast Lane
   10-14-2006 · ScienceDaily
   The speed of nanoparticle assembly can be accelerated with the assistance of DNA, a team of researchers at the US Department of Energy's Brookhaven National Laboratory recently found. Learning how to control the assembly of these miniscule particles into larger systems remains a major challenge for scientists. The Brookhaven results, published online on October 11, 2006, by the Journal of the American Chemical Society, are a step in that direction.

5. Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
   10-14-2007 · EurekAlert!
   A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

9. In early embryos, cilia get the message across
   10-19-2006 · EurekAlert!
   How a perfectly symmetrical embryo settles on what's right and what's left has fascinated developmental biologists for a long time. The turning point came when the rotational beating of cilia, hair-like structures found on most cells, was identified as essential to the process. Now, scientists at the Salk Institute for Biological Studies take a step back and illuminate the molecular process that regulates formation of cilia in early fish embryos.

10. Robotics lab helps stroke patients with recovery
    12-04-2007 · EurekAlert!
    Robotics engineers at Rice University are teaming with doctors from Houston's Memorial Hermann/TIRR to develop a PC-based system for stroke rehabilitation. Sixteen patients are testing a prototype system. They use joysticks to move objects on a computer screen. Using force-feedback technology, the joystick resists moves in the wrong direction and guides patients along the right path. Researchers hope to refine the system to allow stroke patients to recover more quickly.
