CoVid19 Update // Sleep and Your Immune System

man-in-bed-struggling-to-sleep-wd-noexp-620x400This week on How On Earth, we produced the entire show out of the studio, explaining one brief glitch. Beth gives a short update on the way the corona virus infects cells and how this entry point can affect people taking blood pressure medications. In our feature interview, Beth talks with Professor Mark Opp, who studies sleep in his lab at the University of Colorado here in Boulder (interview starts at about 10 minutes). He’s especially interested in the interaction between sleep and our immune systems. Not that long ago, people didn’t think there was any relationship between the two, but our understanding of both systems has evolved.

Paternity Science



This week on How on Earth, Beth interviews Nara Milanich, author of Paternity: The Elusive Quest for the Father, and professor of history at Barnard College. For most of human history, paternity was uncertain while motherhood most definitely was not. But in the 1920s new scientific advances promised to solve the mystery of paternity. The stakes were high: fatherhood confers not only patrimony and legitimacy but also a name, nationality, and identity. We explore the new science of paternity, and some of the complexity of this issue. You can find out more about the book here.

Email troubles (science [a]

Today it came to our attention that our show email address,, was not reliably forwarding messages for the last month or so. We know of at least a few people who tried to contact us via that address and whose messages were swallowed up by the internet. To them—and to the ones we don’t yet know about—we are deeply sorry for the trouble you experienced!

The problem has been fixed, but unfortunately we cannot recover messages that failed to go through.

If you emailed us after June 13th, please resend your message ASAP—especially if it was a submission to our theme song contest! We had no idea we were missing out on your amazing music, and we very much want you to be considered in the contest. Though tonight is the official deadline, we will of course accept any submissions that were lost due to this email issue, provided they are resubmitted in a timely fashion.

Again, to all our listeners, we’re sorry for any anxiety or inconvenience we have caused. Thanks for bearing with us and, as always, thanks for listening!
