As Hurricanes Approach, the Robotic Storm Chasers of the Future Are Ready | Popular Sci... - 0 views

  • Authorities like NOAA gather storm data from a few different sources--from aircraft circling the weather system from tens of thousands of feet, from stationary weather buoys scattered throughout the Gulf of Mexico, from Earth-orbiting satellites--giving scientists a great view of the area around the storm.
  • “Currently there are only two or three ways to get this kind of data,” Dr. Alan Leonardi, deputy director of NOAA’s Atlantic Oceanographic and Meteorological Laboratory, says. “First, you can have a storm serendipitously traverse over a buoy that happens to already be in the water, and that doesn’t happen as frequently as some might believe. Another would be to position a ship out there to collect this data, but that creates a dangerous situation for any crew that might be aboard the ship, so we’re not going to do that. The third--and we have done this--is to deploy instruments from aircraft in front of a storm that can collect data as the storm passes. We then go back in a ship and pick up those buoys--if they survive and don’t end up sinking.”
  • NOAA’s two robotic platforms are being developed independently of one another, yet their roles dovetail neatly. The Liquid Robotics Wave Glider platform is designed as a kind of storm monitoring sentry--like a weather buoy, but one that researchers can move at will. Wave Gliders harvest their propulsive energy from ocean waves themselves and power their onboard electronics with solar energy. This means they are not very fast--too slow to actually chase a storm in most cases--but they can remain at sea for months on end, waiting and watching.

  • the agency already has one Wave Glider in the water north of Puerto Rico as a test-bed for the dozens NOAA hopes will follow. Isaac tracked south of Puerto Rico and missed the prototype, but the robot did manage to capture data from some intense weather along the outer bands of the system--the first of what NOAA hopes will be a new wealth of hurricane data produced by its robotic fleet.
  • the eyewall--the ring of powerful thunderheads that encircle the eye of the storm.
  • With an operational life of ten days, EMILY can be dropped into the water ahead of a storm, navigate its way into the very center, and remain there, tracking the storm as it moves while streaming data all along the way.
  • Better hurricane prediction translates directly to lowered economic losses, better mitigation of property damage, and--as it goes without saying on the eve of Katrina’s anniversary--lives saved.

    As the 2012 hurricane season reaches full tilt, researchers at NOAA are hard at work hacking two different maritime robots that the agency hopes will become critical storm forecasting tools of the future. The first, Liquid Robotics' Wave Glider, is envisioned as a persistent surveillance platform, an army of mobile monitoring stations that will remain at sea for the duration of a hurricane season, waiting to swarm into the path of a developing storm. The second--Hydronalix's Emergency Integrated Life Saving Lanyard, or EMILY (a 2010 PopSci Best of What's New award winner)--will be capable of tracking the storm itself for days at a time, streaming continuous data directly from the center of the storm to researchers ashore.

Robotic Limbs that Plug into the Brain | KurzweilAI - 0 views

  •  
    A new generation of much more sophisticated and lifelike prosthetic arms, sponsored by DARPA, may be available within the next five to 10 years. Two different prototypes that move with the dexterity of a natural limb and can theoretically be controlled just as intuitively - with electrical signals recorded directly from the brain - are now beginning human tests.

Stamping out low-cost nanodevices | KurzweilAI - 0 views

  •  
    A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials has been developed by researchers at Vanderbilt University. The new method works with porous nanomaterials that are riddled with tiny voids, which give them unique optical, electrical, chemical, and mechanical properties. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others. The technique involves the creation of pre-mastered stamps using traditional, but complex, clean room processes and then using the stamps to create patterns using a new process called direct imprinting of porous substrates (DIPS). DIPS can create a device in less than a minute, regardless of its complexity. The smallest pattern the researchers have made to date has features of only a few tens of nanometers (about the size of a single fatty acid molecule). They have also succeeded in imprinting the smallest pattern yet reported in nanoporous gold, one with 70-nanometer features. The first device the group has created is a "diffraction-based" biosensor that can be configured to identify a variety of different organic molecules, including DNA, proteins and viruses. The researchers envision a wide range of applications including drug delivery, chemical and biological sensors, solar cells, and battery electrodes.
