If discovering and designing next-gen materials is like cooking, Duke engineer Cate Brinson is writing the materials cookbook.

If the last year has shown us anything, it’s that fast and accurate diagnostic tests are key for helping to control the spread of a dangerous disease. In this episode, Duke BME’s Ashutosh Chilkoti and his PhD students explain how the lab’s signature diagnostic platform is being modified to quickly and accurately detect COVID-19.

Between measuring our activity levels, heart rate and sleeping schedules, today’s smart watches seem to give us a better picture of our overall health. Duke BME’s Jessilyn Dunn explores the endless potential—and hidden limitations—of this data.

Women and girls are disproportionately affected when access to safely managed sanitation is lacking. Duke ECE engineer Sonia Grego wants to change that.

Washing our hands with soap and running water for at least twenty seconds helps prevent the spread of pathogens. For areas of the world where water is scarce, ECE faculty member Brian Stoner and his colleagues at WaSH-AID are reclaiming usable water from an unlikely source.

A conversation with Henry Petroski on the current state of disrepair of America’s roads and bridges, why fixing them may require unpopular politics, and what the future might hold for their improvement

Po-Chun Hsu is developing textiles that heat and cool at the individual level—a scaled-back approach to climate control that could help curb emissions in the U.S.
