The year-round sea ice in the Arctic is melting and has shrunk by nearly 40 percent over the past four decades. Geoengineering companies such as Real Ice are betting big on refreezing it. That may sound ridiculous, impractical or risky—but proponents say we have to try. The U.K. government seems to agree, investing millions into experimental approaches such as Real Ice’s. Pulitzer Center Ocean Reporting Fellow Alec Luhn is taking us with him to the Arctic to see what it takes to freeze sea ice in the already freezing cold.

Measles was technically “eliminated” in the U.S. in 2000 thanks to high measles, mumps and rubella (MMR) vaccination rates. While prior outbreaks have made headlines, a slew of cases in West Texas is more than just newsworthy—it could cause the U.S. to lose elimination status. Associate health and medicine editor Lauren Young explains what elimination means, why measles cases are rising and how to prevent further transmission.

A 1970s Soviet spacecraft is hurtling down from space—and no one knows where it will land. All 28 of the most populous cities in the U.S. are slowly sinking. Investments and overconsumption make the wealthiest 10 percent of the global population responsible for two thirds of climate-change-related warming.

We’re taking a field trip to the U.S.’s only particle collider, the Relativistic Heavy Ion Collider (RHIC), housed at Brookhaven National Laboratory. Staff scientist Alex Jentsch takes listeners through some basic terminology and interconnected technologies that help Brookhaven researchers probe questions about our unseen universe. The RHIC is winding down in preparation for the new Electron-Ion Collider, which could help us discover the secrets of the “glue” that holds visible matter together. 

Be sure to head over to our YouTube account to see the video version of this podcast, shot on-site at Brookhaven National Laboratory!

The congressionally mandated National Climate Assessment grinds to a halt. Amazon launches its first round of Internet satellites. The European Space Agency launches a satellite to measure the biomass of Earth’s trees. New data from NASA’s Juno spacecraft offer insights into Jupiter and Io. Claims of Tyrannosaurus rex leather are, predictably, misleading.

Conservationists are ringing the alarm about the fungi facing extinction. The International Union for Conservation of Nature (IUCN) Red List features vulnerable pandas and endangered tortoises, but it also highlights more than 400 fungi species that are under threat. Gregory Mueller, chief scientist emeritus at the Chicago Botanic Garden and coordinator of fungal conservation programs at the IUCN, and Anders Dahlberg, a professor of mycology at the Swedish University of Agricultural Sciences, explain the critical role fungi play in our environment and ways we can protect these threatened species.

Griefbots, artificial intelligence chatbots that mimic deceased loved ones, are increasingly in popularity. Researcher Katarzyna Nowaczyk-Basińska reflects on what death, grief and immortality look like in the digital age. She shares insights from a project that she is leading as a AI2050 Early Career Fellow: Imaginaries of Immortality in the Age of AI: An Intercultural Analysis. Plus, we discuss the ethical and privacy concerns surrounding how the data of the deceased are used and what consumers should be on the lookout for if they want to use griefbots.
