Science Friday Folgen

Astronomers using the James Webb Space Telescope have observed clouds on a hot gas giant exoplanet called WASP-94A b, some 700 light-years away. But these clouds aren’t your usual wisps of water vapor—they’re vaporized sand. Astronomer David Sing joins Host Flora Lichtman to describe the planetary weather, and how the researchers were able to observe it.  Then, ecologist Elske Tielens joins Flora to describe how ecologists using weather radar data counted the insects aloft in U.S. skies: around 100 trillion of them on an average summer day. Guests: Dr. David Sing is a Bloomberg Distinguished Professor of Earth and Planetary Sciences at Johns Hopkins University. Dr. Elske Tielens is an ecologist with the Swiss Federal Institute for Forest, Snow and Landscape Research.

It’s common knowledge that many diseases and conditions have some kind of genetic link. But that wasn't always the case. In 1990, long before the Human Genome Project tied so many health issues to differences in genetics, researchers identified a gene called BRCA1. It was the first gene linked to a hereditary form of any common cancer. People with certain variants of BRCA1 stood a higher risk of developing breast and ovarian cancer than those without those mutations.   Geneticist Mary-Claire King and her lab were the first to identify that gene. She joined Host Flora Lichtman in September 2025 to talk about her background, her research, and her approach to science. Guest: Dr. Mary-Claire King is an American Cancer Society Professor in the departments of Genome Sciences and Medicine at the University of Washington in Seattle.

Old creepy houses are a horror cliche, but why? Why do they freak us out? According to new research, it might have something to do with infrasound: a sound that’s below the range of human hearing, potentially emitted by low-rumbling pipes or old boilers more common in older houses.   Psychologist and pseudoscience researcher Rodney Schmaltz explains his new study, and what role infrasound could play in leading people to feel unsettled in “haunted” places. Then, infrasound researcher Milton Garcés breaks down the infrasound that’s produced by volcanoes and asteroid impacts, and how it serves as a “keep away” signal in nature. Guests: Dr. Rodney Schmaltz is a professor of psychology at MacEwan University in Edmonton, Alberta. Dr. Milton Garcés is a research scientist at the Hawai‘i Institute of Geophysics and Planetology and director of the Infrasound Laboratory at the University of Hawai’i in Honolulu.
