Science Friday Folgen

On a hot summer day, there’s nothing better than a dip in a cold pool. But you know who can ruin that for you? A scientist who studies pool chemistry. What chemical reactions are happening in that swimming pool when the water comes into contact with our bodily fluids and skin products? Environmental engineer Ernest Blatchley sits down with Flora Lichtman to discuss his findings after two decades of research, including how urine in a pool makes that chlorine smell, and his work to make the air of the Paris Olympics’ indoor pools less toxic. Guest: Dr. Ernest Blatchley is a professor of environmental engineering at Purdue University, based in West Lafayette, Indiana.

The federal Office of Management and Budget (OMB) has proposed rule changes that would bring a major shift in how scientific grants are awarded by U.S. government agencies. Under the current process, researchers submit grant proposals that are then vetted and scored by a committee of experts in that scientific field, with top-scoring proposals recommended for funding. If its proposed changes are enacted, the OMB would insert a political review into the process, allowing administration officials to determine whether grant proposals are aligned with administration priorities, regardless of their scientific merit. Those proposed rules are now in a public comment period. Holden Thorp, editor in chief of the Science family of journals, joins Ira to explain why he called the change “another red alert for American science” in a recent editorial. Guest: Dr. Holden Thorp is editor in chief of the Science family of journals, at the American Association for the Advancement of Science.

If you have arachnophobia, consider this your opportunity to try exposure therapy: A new study suggests that 415 million years ago, in modern-day England and Wales, a scorpion the length of a golden retriever was scurrying around, complete with 6-inch pincers. Flora talks with lead study author Richie Howard about the finding. If you’re grossed out by a 3-foot scorpion, you’re not alone. But, scorpion researcher Lauren Esposito says we’ve got it all wrong—scorpions are wonderful and caring creatures. Guests: Dr. Richie Howard is an invertebrate paleontologist and curator of fossil arthropods at the Natural History Museum in London, England. Dr. Lauren Esposito is a scorpion researcher and director of the non-profit Islands and Seas and founder of 500 Queer Scientists.
