Science: Vikings In North America, Magnets Moving Non-Magnetic Metals
An ancient solar storm helps pinpoint when Vikings lived in the Americas, and using magnets to deftly move non-magnetic metals.
In this episode:
00:53 Pinpointing Viking presence in North America
It’s well-understood that Vikings went to North America around a thousand years ago. However, working out a precise date has proven difficult. Now, thanks to an ancient solar storm, researchers have been able to identify an individual year when Vikings were definitely living on the continent.

Covid-19: Molnupiravir – Merck’s Antiviral Drug
Molnupiravir (MK-4482, EIDD-2801) is an investigational oral antiviral medicine that significantly reduced the risk of hospitalization or death at a planned interim analysis of the Phase 3 MOVe-OUT trial in at risk, non-hospitalized adult patients with mild-to-moderate COVID-19. At the interim analysis, molnupiravir reduced the risk of hospitalization or death by approximately 50%; 7.3% of patients who received molnupiravir were either hospitalized or died through Day 29 following randomization (28/385), compared with 14.1% of placebo-treated patients (53/377); p=0.0012. Through Day 29, no deaths were reported in patients who received molnupiravir, as compared to 8 deaths in patients who received placebo.
Science: Ripple Effects Of Mass Incarceration, Dog-Sniff Evidence Reliability
This week we are covering the Science special issue on mass incarceration. Can a dog find a body? Sometimes. Can a dog indicate a body was in a spot a few months ago, even though it’s not there now?
There’s not much scientific evidence to back up such claims. But in the United States, people are being sent to prison based on this type of evidence. Host Sarah Crespi talks with Peter Andrey Smith, a reporter and researcher based in Maine, about the science—or lack thereof—behind dog-sniff evidence.
With 2 million people in jail or prison in the United States, it has become incredibly common to have a close relative behind bars. Sarah talks with Hedwig Lee, a sociologist at Washington University in St. Louis, about the consequences of mass incarceration for families of the incarcerated, from economic to social.
