Device traps, disables harmful bacteria

A team of engineers from Washington University in St. Louis and the University of Colorado at Boulder has removed bioaerosols – airborne biological particulate matter — from the air of a hospital therapy pool using a new generation of hybrid filters. The bioaerosols identified in the unnamed Midwestern hospital pool had sickened nine lifeguards who had become ill with hypersensitivity pneumonitis, a lung condition that mimics pneumonia symptoms. This forced the pool to shut down. It is now reopened.

Gamers’ brains no different than yours or mine

Gamers are faster than you and I.While Mortal Combat, Grand Theft Auto, or Halo may be foreign to aging generations, a new study out of Washington University in St. Louis and the University of Toronto suggests that video games like these promote a kind of mental “expertise” that could prove to be useful in the non-virtual world — potentially in rehabilitation and for the elderly. Alan Castel, Ph.D., Washington University post doctorate fellow in psychology in Arts & Sciences, conducted a study to examine how video games can lead to a degree of expertise in certain domains, and how that might influence video game players’ visual search patterns.

Map of life on Earth could be used on Mars

Carinne Blank has a method she uses to date ancient life forms that could be helpful for specimens from Mars.A geologist from Washington University in St. Louis is developing new techniques to render a more coherent story of how primitive life arose and diverged on Earth – with implications for Mars.

Despite hurdles, human missions to Mars are in the works

Mars Exploration Rover mission scientists remind us that the amazing success of the rovers *Spirit* and *Opportunity* is a harbinger for the day when humans inhabit the Red Planet.The major drawback to a human mission to Mars is preparing for the one to two years of radiation and microgravity exposure that astronauts must endure. While that is a large hurdle, enabling technologies are emerging that should be able to make this goal a reality over the next couple of decades, and America should go for it. That’s the theme of a report from NASA’s 2002 Astrobiology Academy appearing soon as a paper in Acta Astronautica.

St. Louis hosts international software engineering conference

St. Louis is the site for the world’s premier software engineering annual conference from May 15-21 at the Adam’s Mark Hotel. The 27th International Conference on Software Engineering (ICSE 2005) features the latest research in software engineering, displays, exhibits, seminars, co-located conferences, and social gatherings that bring the world’s elite together in an unprecedented hub of activity in information technology (IT) in the Gateway City. Gruia-Catalin Roman, Ph.D., Harold B. and Adelaide G. Welge Professor of Computer Science and chair of the Department of Computer Science and Engineering at Washington University in St. Louis, is the general chair for ICSE 2005 and was highly influential in bringing the conference to St. Louis,
