The Webb Space Telescope picked up traces of dimethyl sulfide on planet K2-18b. On Earth, the molecule comes from microbes and phytoplankton. Also, researchers captured the first confirmed video of a colossal squid swimming in its natural habitat—almost 2,000 feet deep.Possible Signature Of Life Detected On Exoplanet—MaybeIn major galactic news, scientists may have detected possible signs of life on a planet right here in our galaxy. Is this one of the best hints we’ve gotten that alien life exists? Host Flora Lichtman gets into it with Anil Oza, the Sharon Begley Science Reporting Fellow at STAT and MIT. They discuss the latest in alien life, the Trump’s administration cuts to the “indirect costs” of science funding, the largest map of a brain yet, and how salmon on anti-anxiety meds make bolder choices.A Colossal Squid Video? That’s A Big DealThis week, scientists announced that they had captured the first confirmed video of a colossal squid in its natural habitat, recorded some 1,968 feet (600 m) below the ocean surface near the South Sandwich Islands. While there have been sightings of the colossal squid before, they have mainly been of individuals entangled with fishing equipment—and much of what is known about the elusive creatures comes from dead specimens.The video was captured by scientists on board the R/V Falkor (too) during an Ocean Census expedition searching for new marine life. As the remotely operated vehicle SuBastian descended towards the ocean floor, its cameras caught sight of a juvenile squid roughly one foot long (30 cm), and captured over a minute of high resolution video. The footage was later analyzed by experts and determined to be a colossal squid.Colossal squid are estimated to grow up to 23 feet (7 m) in length and can weigh as much as 1,100 pounds (500 kg), making them the heaviest invertebrate on the planet. They are not the same as the giant squid, an entirely different species, which can grow to be longer but are lighter and slimmer.Dr. Kat Bolstad, one of the squid experts the researchers sent their videos to for identification, joins Host Flora Lichtman to talk about the sighting.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Imagine you’re diving into a cell. You’re paddling around in the cytoplasm, you’re climbing up a mitochondria. If you’re having a hard time picturing this, that’s okay! There are professionals who do this for a living.We wanted to learn more from expert science interpreters, who take the results section of a research paper and translate it into something tangible, like a 40-foot dinosaur skeleton or a 3D animation of cellular machinery too small to see.At a live event in Salt Lake City in March, Host Flora Lichtman spoke with Dr. Janet Iwasa, head of the University of Utah’s Animation Lab and director of the Genetic Science Learning Center; and Tim Lee, director of exhibits at the Natural History Museum of Utah, about how they bring these out-of-reach worlds to life.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Bringing back Southwest peach orchards won’t be easy, but researchers are on the lookout for remaining trees—and they need help. And, the newly discovered Lokiceratops is challenging paleontologists’ understanding of how horned dinosaurs evolved and existed together. How A Navajo Plant Researcher Is Reviving A Desert PeachWhen you think of states known for their peaches, Utah might not be at the top of your list. But there is a variety—the Southwest peach—that grows in this arid landscape, and Native communities have cultivated this tree since the 1600s. But many of the orchards were intentionally destroyed by colonizers hundreds of years ago, and the remaining trees are now scattered across the region.A local scientist and member of the Navajo Nation is on a mission to track down Southwest peach trees so we can learn more about how these peaches are so well-suited to grow in the desert.At a live event in Salt Lake City in March, Host Flora Lichtman spoke with Reagan Wytsalucy, plant scientist and assistant professor at Utah State University Extension in San Juan County, Utah. She researches traditional Native American crops, including the Southwest peach.Meet Lokiceratops, A Giant Dinosaur With Blade-Like HornsThe Intermountain West is a dinosaur nerd’s dream because it’s such a hotspot for fossils. Some of the most famous dino fossils in the world, like T. rex, triceratops, and stegosaurus can be found in western North America. So, of course, Science Friday couldn’t go to Salt Lake City, Utah, without digging into some dinosaur science.At a live event in Salt Lake City in March, Host Ira Flatow spoke with the scientists behind the discovery of Lokiceratops, a large dinosaur with impressive horns that was unveiled in 2024. Dr. Mark Loewen, vertebrate paleontologist at the University of Utah and the Natural History Museum of Utah; and Savhannah Carpenter, paleontologist and school outreach coordinator at the Natural History Museum of Utah, discuss how they figured out Loki was a new dinosaur, the process of describing and naming the fossil, and what it taught them about dino evolution.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.
