Children’s Antibiotics Shortage, Bat Vocalizations, Life’s Biggest Questions. January 20, 2023, Part 1

Why Are Children’s Antibiotics So Hard To Find Right Now?

Mary Warlo has been extremely worried lately. Her baby Calieb, who is six months old, has sickle cell disease. In early December he went for a few days without liquid penicillin, a medication that he—and thousands of other children in the U.S.—rely on to prevent potentially life threatening infections.

Warlo couldn’t easily find a pharmacy in Indianapolis that had the medicine in stock. She and her husband frantically drove around for hours, stopping at five different pharmacies before they were able to get their prescription filled. “It was extremely stressful and I am worried about what will happen the next time we need to fill his prescription two weeks from now,” she said. Pediatric sickle cell disease specialists say they are alarmed by signs that the stock of liquid penicillin is dwindling in some places. They say children’s lives depend on this medication, and a penicillin shortage could spell disaster.

Bats Use Death Metal 'Growls' To Make Social Calls

What do death metal vocalists and bats have in common? Both use their ventricle folds, or “false vocal cords,” to extend their vocal ranges to hit a lower register. This gives bats a huge vocal range—seven full octaves. Humans typically tap out at about three to four octaves. Even people with really impressive vocal ranges, like Mariah Carey, just can’t compete with a bat.

A study recently published in the academic journal PLOS Biology examines how and why different anatomical structures might help bats achieve such extreme frequency range. Ira talks with one of the study’s authors, Coen Elemans, a professor in bioacoustics and animal behavior at the University of Southern Denmark based in Odense, Denmark.

Can Science Answer Life’s Biggest Questions?

Dr. Alan Lightman has been around the block a few times. Over the past five decades, he has been a theoretical physicist, professor at MIT, and bestselling author—often at the same time. His most notable novel, Einstein’s Dreams, has been adapted into dozens of plays and musicals since its publication in 1992, becoming one of the most famous examples of mixing art and science.

Lightman’s work follows a philosophical way of thinking about life’s biggest questions, like the origins of consciousness. His new venture brings this way of thinking to the silver screen. Searching: Our Quest for Meaning in the Age of Science consults scientists and faith leaders to grapple with some of these theoretical quandaries. And Lightman gives a good argument for why the journey to these answers can be more impactful than the answers themselves.

Ira speaks with Alan Lightman about the new program, available to watch now online and on your local public television station.
