Practices as simple as using compost, reducing soil disturbance and rotating crops could enable the world's farmland soil to absorb as much atmospheric carbon as is emitted by the global transport sector, per a study published in Nature's Scientific Reports journal. Better soil management would also "make our agricultural systems more productive and resilient to future shocks and stresses," said Louis Verchot, one of the study's authors.

Waiting to replace a part when it fails can be costly in more than one sense, as the part might have operated below an optimal level for some time before it finally gave out. Enterprise Asset Management, or EAM, provides a more strategic approach to maintenance, and key to this is visibility, with sensors that provide real-time data on every device and component to signal developing problems before they hit the critical stage.

The depths of the world's oceans largely remain a mystery, and learning and mapping more for a variety of purposes is likely to fall increasingly to robots. Melissa Hebert looks at how robotics and artificial intelligence will be applied in ways that advance mining, national security and the environment.

Organic electronics useful in such applications as flexible electronics and solar energy conversion are taking a step forward, thanks to research at Princeton University, the Georgia Institute of Technology and Humboldt University of Berlin. The semiconductors used in these electronics are made up of relatively low-conductivity carbon molecules rather than silicon, and researchers have found that doping them with a ruthenium-containing compound greatly increases their conductivity.

The Tesla Semi is an all-electric semitrailer designed to automatically avoid jackknifing and travel 500 miles on a single charge. The battery-powered, nearly all self-driving truck can go from zero to 60 mph in five seconds without a trailer and could be less expensive to operate than trucks that run on diesel.

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.
