Discovery of size changes of Bacillus spores may lead to simpler, faster anthrax detector
...The system relies on filtering air and sending the filters
to a lab, where any attached microbes would be cultured and identified. Even with advanced techniques such as PCR (polymerase chain reaction) to detect microbial genes, the turnaround time would be 12-24 hours. A device to scan for Bacillus spores of...
Wetlands clean selenium from agricultural runoff
...lly learning that some of the best, most efficient filters

Ames chemist wins national award for contributions to Human Genome Project
...k out compounds into colored bands. Now high-speed filters
and computers can detect and quantify a trace of pollutant in a sample of air or the sequence of genetic code in a human gene. Indeed, it is Yeungs contribution to the Humane Genome Project in the early 1990s, using technology then available, that he...
Portable unit created to treat wastewater in remote locations
...UTD developed stainless steel screens and pressure filters
for solids removal. These will be used in conjunction with biological treatment units where bacteria are used to degrade the waste using a fixed media comprised of clay beads. Bacteria are grown on the beads, which allows a high quantity of microbes...
Endangered freshwater mussels saved
...s says, because mussels are the natural biological filters
in the river system. They remove sediment, contaminants, and particles, ingesting some and releasing the rest into mucus strings. Some water insects feed on these strings, and the mussels themselves serve as a food source for raccoons, muskrats, rive...
