ASU computing experts are using satellite images to help humanitarian organizations provide disaster relief to cyclone-ravaged Myanmar. The images could help determine if aircraft could land in an area or if roads are blocked, for example. --by Joe Kullman

Nanomaterials are in or on the surface of thousands of the products you use every day. They are part of toothpaste, stain-resistant clothing, sunscreens, plastic water bottles, and more. ASU researchers want to know if these microscopic materials are also making their way into the environment, drinking water and, ultimately, your body. --by Melissa Crytzer Fry

Major league baseball players like Derek Jeter make actions like catching a fly ball look effortless. But if you want to understand the complexity underlying these moves, try teaching them to a robot. By combining expertise in engineering and psychology, ASU researchers have created Catchbot, a baseball-playing robot. In the process, they have learned a lot about how people perceive and respond to a moving target. --by Skip Derra

To humans, trichloroethene (TCE) is a dangerous pollutant, one that recently forced two Phoenix-area municipalities to shut down their water supplies. But to a group of bacteria called dehalogenerators, TCE is like oxygen. These microorganisms take in TCE and remove the chlorine, leaving harmless ethene behind. Now a team of scientists has developed a specialized water treatment system that employs the bacteria to make water supplies safer. --by Joe Caspermeyer

We've all heard that playing video games can improve your hand-eye coordination--usually from kids trying to evade mom's order to go play outside. But those kids may be on to something. New research shows that playing a video game on the Nintendo Wii can help medical students become better surgeons by improving hand dexterity. --by Joe Kullman

Scientists at ASU have developed the world's first gene detection platform made up entirely from self-assembled DNA nanostructures. The structures are made using "DNA origami" techniques to create spatially addressable nanoarrays. The work could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell. --by Joe Caspermeyer

Microbial fuel cell technology uses the tiniest organisms on the planet--bacteria--as a viable option to make electricity. By linking bacterial metabolism directly with electricity production, the MFC eliminates the extra steps necessary in other fuel cell technologies. --by Joe Caspermeyer

An ASU researcher has designed a special backpack that can produce an electrical charge through the force of the motion of its wearer. This "energy harvesting" can generate the power to charge batteries or run small electronic devices such as cell phones, iPods or flashlights. --by Joe Kullman

A team of scientists has developed a new way to close the gaps in the global pollution dragnet using NASA satellite data. The technique uses satellite information to improve computer models of ozone events–filling in the blanks while expanding coverage to much larger areas. --by Nicholas Gerbis

The unknown health and environmental effects of
nanotechnology are a bigger worry for scientists than for the public,
according to a new report. --by Skip Derra
