A long-awaited rule from the EPA limits the amounts of six PFAS chemicals allowed in public drinking water supplies. Also, some spiders, beetles, and centipedes spend winter under snow in a layer called the subnivium. Plus, a drumroll for the total solar eclipse.

EPA Sets Limits On ‘Forever Chemicals’ In Drinking Water

This week, the EPA finalized the first-ever national limits for the level of PFAS chemicals that are acceptable in drinking water supplies. Those so-called “forever chemicals,” per- and polyfluoroalkyl substances, have long been used in products like fire retardants and oil-and water-repellent coatings, and are now ubiquitous in the global environment. Water treatment plants will now have to test and treat for several varieties of the chemicals, which have been linked to a variety of health problems in people.

Sophie Bushwick, senior news editor at New Scientist, joins SciFri producer Kathleen Davis to talk about the rule and its potential impact on water agencies. They’ll also talk about other stories from the week in science, including research into a new vaccine against urinary tract infections, theories that extend the multiverse into a many-more-worlds interpretation, the passing of particle physicist Peter Higgs, and a new front in the war on pest rats: rodent contraceptives.

Where Snowpack Meets Soil: An Important Winter Home For Bugs

When winter rolls around and snow piles up, many insects head down to a small layer called the subnivium for the season.. This space, between snowpack and soil, shelters small insects, amphibians,and mammals from freezing temperatures.

Arthropods as a whole are understudied, says Chris Ziadeh, graduate of the University of New Hampshire and lead author of a recent study about the distinct communities that live in the subnivium. Better understanding which creatures call the subnivium home in the winter, as well as their behavior, could help us conserve them as the climate warms.

Guest host Kathleen Davis talks to Ziadeh about winter arthropod activity, species diversity, and why we should all care about protecting insects in our communities.

Drumroll Please! A Performance For The Solar Eclipse

People found all manner of ways to celebrate the solar eclipse that happened earlier this week, but one Science Friday listener found a particularly musical way to take in the experience.

Matt Kurtz, a sound artist and musician based in Akron, Ohio, realized his town would be in the path of totality for the April 8 eclipse. So with some funding from Akron Soul Train, a local artist residency, he put together a percussion section (complete with a gong) to perform a drumroll and build suspense up until the moment of totality. They performed in Chestnut Ridge Park to a crowd of onlookers.

“When you hear a [drumroll], it forces you to be like, something’s about to happen,” he said in an interview. “It’s a way to pay attention.”

As the gong rang out and the crowd cheered, Kurtz put down his sticks and experienced his first solar eclipse totality. “It was a release,” he said. “I had a couple minutes of peace where I got to look at the stars and feel where all this work went to.”

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
