Online News Editor David Grimm talks with producer Joel Goldberg about the unique challenges of reopening labs amid the coronavirus pandemic. Though the chance to resume research may instill a sense of hope, new policies around physical distancing and access to facilities threaten to derail studies—and even careers. 

Despite all the uncertainty, the crisis could result in new approaches that ultimately benefit the scientific community and the world. Also this week, Joel Podgorski, a senior scientist in the Water Resources and Drinking Water Department at the Swiss Federal Institute of Aquatic Science and Technology, joins host Sarah Crespi to discuss the global threat of arsenic in drinking water. Arsenic is basically present in all rocks in minute amounts. Under the right conditions it can leach into groundwater and poison drinking water. Without a noticeable taste or smell, arsenic contamination can go undetected for years. The paper, published in Science, estimates that more than 100 million people are at risk of drinking arsenic-contaminated water and provides a guide for the most important places to test.
