A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity’s oldest technologies – and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.

A University of Washington bioengineer recently developed a way to make regular paper stick to medically interesting molecules. The work produced a chemical trick to make paper-based diagnostics using plain paper, the kind found at office supply stores around the world. (more…)

Engineers at Yale University have developed a new, highly efficient technique for separating, sorting, and concentrating synthetic microscopic particles within complex fluids based on size.

The new technique suggests the possibility of significant clinical, diagnostic, and pharmaceutical applications, such as isolating rare liquid-borne pathogens, monitoring tumor cells in bloodstreams, and rapidly assessing blood cell counts, for example. (more…)

ANN ARBOR, Mich.— While debate on climate change often strikes a caustic tone, the real impediment to meaningful dialogue is that the two sides often talk past each other in what amounts to a “logic schism,” says a University of Michigan researcher.

“In a logic schism, a contest emerges in which opposing sides are debating different issues, seeking only information that supports their position and disconfirms their opponents’ arguments,” said Andy Hoffman, the Holcim (U.S.) Professor of Sustainable Enterprise at U-M’s Ross School of Business and School of Natural Resources and Environment. “Each side views the other with suspicion, even demonizing the other, leading to a strong resistance to any form of engagement, much less negotiation and concession.” (more…)
