As medical researchers and engineers try to shrink diagnostics to fit in a person’s pocket, one question is how to easily move and mix small samples of liquid.

University of Washington researchers have built and patented a surface that, when shaken, moves drops along certain paths to conduct medical or environmental tests.

“This allows us to move drops as far as we want, and in any kind of layout that we want,” said Karl Böhringer, a UW professor of electrical engineering and bioengineering. The low-cost system, published in a recent issue of the journal Advanced Materials, would require very little energy and avoids possible contamination by diluting or electrifying the samples in order to move them.

The communities of marine microorganisms that make up half the biomass in the oceans and are responsible for half the photosynthesis the world over, mostly remain enigmatic. A few abundant groups have had their genomes described, but the natures and functions of the rest remain mysterious. (more…)

Gulf Coast Monitor: Sensor Designed to Detect Oil Contaminants in Saltwater

With more than 20,000 abandoned and active gas and oil wells in the Gulf of Mexico, oil leaks and spills pose a continuous threat to the region’s ecosystem. Monitoring the health of the ecosystems helps ensure the sustainability of natural resources, and helps protect human health and the environment.

Researchers at the Georgia Tech Research Institute (GTRI) are developing an advanced-warning system to detect the presence of oil in saltwater. The sensor-based system offers the potential for remotely, autonomously and continuously monitoring bodies of water for oil. (more…)
