A Kelvin wave has reached California and is creeping up the West Coast, raising both sea levels and concerns from government officials. This kind of massive internal wave begins in the western Pacific Ocean and then travels eastward to the Americas along the equator, and then up and down the coastline. While it might raise sea levels up to 12 inches, it stays below the surface instead of crashing on the shore.

Host Flora Lichtman speaks to oceanographer Andrew Leising to get the lowdown on what exactly a Kelvin wave is, and how wary West Coasters should be.

Guest:

Dr. Andrew Leising is a research oceanographer at NOAA Southwest Fisheries Science Center in San Diego, California.

Cephalopods have a reputation for being smart and majestic. And while that may be true, the life of a cephalopod can also be dark and gritty. Have you heard of octopus death spirals? How about cephalopod cannibalism? 

Host Flora Lichtman is joined by cephalopod experts Heather Judkins and Z. Yan Wang for a conversation about the weirdest parts of being a cephalopod, and to answer some listener questions.

It’s Nobel Prize week, and this year's prize in physics went to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” The IceCube is a massive neutrino detector that covers a cubic kilometer of Antarctic ice, and looks for high-energy neutrinos coming from deep space. 

In 2013, Ira spoke with physicist Francis Halzen about the decision to build the IceCube at the South Pole and the challenges of constructing a map of the cosmos with neutrinos.

Guest:

Dr. Francis Halzen is a professor of physics at the University of Wisconsin–Madison and the 2026 recipient of the Nobel Prize in physics.

On Science Friday, we love to talk about ideas, especially ideas that have the power to shape the future. But there are plenty of groundbreaking ideas that almost don’t make it out of the lab or the art studio: ideas that are birthed but then fall into a deep slumber until, years later, they’re reawakened.

Why this happens is the subject of the new book, “Sleeping Beauties: Why Good Ideas Go Dormant and How They Wake Up,” by David Bryne, artist, musician, and lead singer for Talking Heads. He joins Flora to explain. 

Watch the interview on YouTube.
