Those ailing in the world's remote areas are the focus of Ramses Martinez, professor of industrial and biomedical engineering at Purdue University, who has developed a diagnostic lab that fits on a sheet of paper. Connected to a simple electronic device, the paper analyzes blood and saliva samples to detect liver and kidney problems, malnutrition and anemia, with future potential to test for malaria, yellow and dengue fevers, hepatitis and HIV.

Engineered bacteria are being put to work in a wide variety of beneficial situations, but there's danger in the likelihood that they will someday find their way out of their intended environments. That's what a research team at Harvard is working on, with one coded-in kill switch that keeps engineered bacteria from evolving and another that instantly kills the bacteria if they escape.

An erosion-fighting project that transformed a steep wash into a shallow basin has earned Cochise County an Arizona Association of Counties award. The Horseshoe Draw Erosion Control Project mitigates flooding, prevents soil loss on range land, and curbs sediment and E-coli flow into the San Pedro River.

A new study assesses Copenhagen's stormwater system within the framework of a Three Point Approach using state-of-the-art modeling. The results confirm multiple advantages -- including better protection against flooding -- for a system that disconnects from the city's combined sewer system during a cloudburst.
