Although it's been several years since the Space Shuttle Columbia disaster, it looks like some of the data gathered during the orbiter's final mission will be put to good use. A hard drive salvaged from the wreckage contains the results of an experiment to study the way xenon gas flows in microgravity, and the results were published in the April edition of a journal called Physical Review E. The 400MB Seagate drive was originally thought to be destroyed, but workers and engineers reconstructing the orbiter from the remaining debris found it during the process and sent it off for recovery, where 99 percent of the data was extracted. It then took several years for lead researcher Robert Berg and his team to analyze the findings, but they're happy with the results -- we only wish they hadn't come at so dear a price.

Advanced voice recognition technology busted one Juan Carlos Ramirez Abadia recently, a drug kingpin who had drastic plastic surgery in a failed attempt to mask his true identity. Because of his plastic surgery, Brazilian Police were unable to gain positive identification required for an arrest warrant. Instead, Colombian officials provided the US Drug Enforcement Agency with taped conversations, which the US body was able to match to Ramirez Abadia. It's not clear how advanced the technology actually is, since the Government keeps it under wraps: judging by the importance of this arrest, and the impending trial, we'd hope that it's beyond the capabilities of regular off-the-shelf desktop software.

While we've seen a few snazzy band-aids in our day, not to mention talking first aid kits, a nanofiber bandage that can heal typical skin wounds faster is about to go mainstream. University of Akron professors Daniel Smith and Darrell Reneker are growing ever closer to bringing their invention to life, as a trial just wrapped up in Columbia that they hope will "win them FDA approval for clinical trials in the United States." The duo used electricity to spin ultrafine polymer fibers while infusing them with chemicals that open a wound to oxygen; then, the treated fibers "reduce inflammation, kill bacteria and repair slow-healing wounds faster than conventional methods," according to Smith. Moreover, the creators have already found a Minnesota-based firm willing to mass produce the nanobandages should they receive the green light, but the professors are hoping to build the new manufacturing plant in Ohio if at all possible, and have products on retail shelves "by 2008" at the latest. Given the presumed popularity of the quick-healing bandages, the team is continuing to work on other "nanofiber products" in their spare time, hoping that the mending aid is just the beginning of a long line of sweet nano-based products to come.

While strands of DNA may be able to pick fights with other strands, one thing that they can't do yet is play computer games -- that is, until now. In what appears to be an early proof-of-concept for DNA computing, scientists at Columbia University and the University of New Mexico have created a basic computer, called the MAYA-II, which has a molecular array of YES and AND logic gates made up of 100 DNA circuits. This allows the MAYA-II to play a complete game of Tic-Tac-Toe against a human opponent, and apparently nearly always win. However, this isn't exactly a fair test, given that the MAYA-II always goes first, and always opens with the center square. Still, even though each move takes 30 minutes to complete, the lead researcher on the project, Dr. Joanna Macdonald of Columbia, says that a DNA computer would be perfect for injection into human subjects to combat disease, because in theory, it would be able to "diagnose and kill cancerous cells or monitor and treat diabetes by dispensing insulin when needed." Useful applications aside, we're ready to take on the MAYA-II in Connect Four whenever Dr. Macdonald thinks it's ready.
