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.
Technology is beginning to change construction sites long resistant to such advances. Michael Abrams looks at six of the technologies that will bring further transformation in the future, including a robot that fabricates construction mesh out of metal bars and gantry-style 3D printing.
Winding up a port call and planning sessions in the Turkish port of Aksaz, the Arleigh Burke-class destroyer USS Donald Cook departed for the Dogu Akdeniz 2017 exercise. The exercise is a multinational affair led by Turkey.
NASA's next Mars rover will need a high-tech parachute to slow its supersonic entry into the thin atmosphere and provide a gentle descent. A nylon-and-kevlar system has passed its first test, deploying at 1,370 mph high in the earth's atmosphere with minimal damage.
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.
Mudslides are likely in areas near California's La Tuna fire, which swept over more than 7,000 acres, and officials are warning residents of Burbank. Engineers are examining the area to project where slides are most likely to happen during the rainy season.
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.
A project to make 60 miles of New Jersey coastline more resilient got under way with the launch of restoration work at a salt marsh in the Cape May National Wildlife Refuge. The $200,000, three-week project will reduce the risk of flooding and benefit wildlife.
A team that includes managers of Oklahoma's Lake Thunderbird is at work on a floating wetlands project to test its effectiveness against bank erosion. The wetlands will serve as a breakwater to calm wave action along the lake's shores and clear the way for vegetation to return.
