The Polarstern research vessel will spend 1 year locked in an Arctic ice floe. Aboard the ship and on the nearby ice, researchers will take measurements of the ice, air, water, and more in an effort to understand this pristine place. Science journalist Shannon Hall joins host Sarah Crespi to talk about her time aboard the Polarstern and how difficult these measurements are, when the researchers’ temporary Arctic home is the noisiest, smokiest, brightest thing around.
After that icy start, Sarah talks also with Tanmoy Samanta, a postdoctoral researcher at Peking University in Beijing, about the source of the extreme temperature of the Sun’s corona, which can be up to 1 million K hotter than the surface of the Sun. His team’s careful measurements of spicules—small, plentiful, short-lived spikes of plasma that constantly ruffle the Sun’s surface—and the magnetic networks that seem to generate these spikes, suggest a solution to the long-standing problem of how spicules arise and, at the same time, their likely role in the heating of the corona.

There was a massive shift in Roman residents’ ancestry, the researchers found, but that ancestry came primarily from the Eastern Mediterranean and Near East, possibly because of denser populations there relative to the Roman Empire’s western reaches in Europe and Africa.

In our second segment, we talk about how we think about children. For thousands of years, adults have complained about their lack of respect, intelligence, and tendency to distraction, compared with previous generations. A new study out this week in Science Advances suggests
