Robot Successfully Explores Gas Mains - SpaceDaily  Left:  The Explorer project's goal is to develop a teleoperated long-range untethered video-inspection of live distribution gas-mains which can traverse 2,500 ft.+ of 6-8 inch I.D. pipe with elbows, operate in a live low/medium pressure steel/cast-iron/plastic gas-main with live control & video feedback. It should navigate 'accurately', be failure-retrievable and require only one operator. Project members are developing a prototype 'crawler' system for live gas-main access with wireless video & data communication with rechargeable battery-power.  Carnegie Mellon University robotics researchers, in conjunction with the Northeast Gas Association, the National Energy Technology Laboratory, and NASA, have developed a remote-controlled, untethered, wireless prototype crawling robot, designed to inspect underground gas mains.
NASA Scientists Study Gene Functions To Treat Diseases - SpaceDaily  NASA scientists have discovered a way to identify the gene functions of all of an organism's genes simultaneously by using unique DNA sequences or 'bar codes.' Scientists at NASA Ames Research Center, Moffett Field, Calif., found that newly validated sequences of synthetic DNA tags, called molecular barcodes, can now be used to accurately characterize gene functions in Saccharomyces cerevisiae, commonly known as baker's yeast. "Understanding yeast gene functions can ultimately result in treatment of human diseases, as many yeast genes have similar functions in human cells," Stolc added.

Snapshots Of Moving Molecules, Taken In A billionth Of A Second - SpaceDaily  A team of researchers including University of California, Riverside Assistant Professor of Chemistry, Ludwig Bartels has developed a technique to take extremely fast snapshots of molecular and atomic movement. The development is considered a significant advance in surface science, the study of chemical reactions taking place on the surface of solids. "Scanning probe microscopy has the capability of reaching directly down to the natural spatial scale of atoms and molecules," Bartels said. "While femtosecond laser techniques have the capability of reaching down to the time scale of atomic events.
