Warren Cornwall, a contributing correspondent for Science Magazine, dives into the destructive urban wildfires in Los Angeles, exploring their impact on air quality and health. He highlights innovative research aimed at understanding pollution from urban fires. Mingze Chen, a mechanical engineering grad student, discusses the challenges of integrating AI into tiny robots. His team’s work with memristors offers a breakthrough in energy-efficient data processing, which could revolutionize robotics and drone technology. A fascinating exploration of science at the intersection of environment and technology!

First up this week, Newsletter Editor Christie Wilcox joins host Sarah Crespi to discuss stories from the sea, including why scientists mounted cameras on seabirds, backward and upside-down; newly discovered organisms from the world’s deepest spot, the Mariana Trench; and how extremely venomous, blue-lined octopus males use their toxin on females in order to mate.

Chris McKnight, a senior research fellow in the Sea Mammal Research Unit at the University of St. Andrews, talks about testing free-living seals to see how they respond to different carbon dioxide or oxygen levels in the air. It turns out they don’t respond like other mammals, which go into panic under high carbon dioxide; instead, seals appear to directly detect oxygen, a safer bet when your life is mostly spent diving deep underwater. This week’s episode was produced with help from Podigy. About the Science Podcast Authors: Sarah Crespi; Christie Wilcox Learn more about your ad choices.

This week features Jocelyn Kaiser, a science policy editor focusing on the NIH, Kathleen O'Grady, who reports on the science-society intersection, and Francesca Fardo, a pain perception researcher. They discuss how using sign language can significantly benefit children with cochlear implants, ensuring better communication. They also explore important NIH funding changes and delve into a fascinating study on how uncertainty affects pain perception, revealing that greater uncertainty can lead to more intense pain experiences.

David Malakoff, International News Editor for Science Magazine, shares vital updates on U.S. science policy under Trump, discussing the impacts of tariffs and employment challenges at the NIH. Andrew Curry and Martin Larmazzo delve into the world of genetic genealogy, revealing surprising truths about extra-pair paternity and historical figures like Beethoven. Meanwhile, Suzanne Schweizer explores intrusive thoughts during pregnancy, emphasizing the mental health challenges that many expectant and new mothers face, advocating for greater awareness and understanding.

First up this week, Kata Karáth, a freelance journalist based in Ecuador, talks with host Sarah Crespi about an effort to identify traditionally prepared shrunken heads in museums and collections around the world and potentially repatriate them. Next, genetically modified Bt corn has helped farmers avoid serious crop damage from insects, but planting it everywhere all the time can drive insects to adapt to the bacterial toxin made by the plant. Christian Krupke, an entomology professor at Purdue University, talks about the economics of planting Bt corn and how farmers could save money and extend the usefulness of this transgenic plant by being selective about where and when they plant it. This week’s episode was produced with help from Podigy. About the Science Podcast Authors: Sarah Crespi; Kata Karáth Learn more about your ad choices.

Martin Enserink, Deputy News Editor at Science, discusses the ethical dilemmas faced by researchers due to funding cuts in USAID-backed studies, emphasizing the impact on trial participants. Sandeep Ravindran shares insights on TinyML technology powering low-cost solutions in agriculture and healthcare, aiding farmers and clinics in the Global South. Michael Barnett reveals his research on evolving evolvability in microorganisms, exploring how these organisms adapt to environmental changes, showcasing the innovative intersection of evolution and technology.

First up this week, International News Editor David Malakoff joins the podcast to discuss the big change in NIH’s funding policy for overhead or indirect costs, the outrage from the biomedical community over the cuts, and the lawsuits filed in response. Next, what can machines understand about pets and livestock that humans can’t? Christa Lesté-Lasserre, a freelance science journalist based in Paris, joins host Sarah Crespi to discuss training artificial intelligence on animal facial expressions. Today, this approach can be used to find farm animals in distress; one day it may help veterinarians and pet owners better connect with their animal friends. Finally, Keya Ghonasgi, a postdoctoral fellow at the Georgia Institute of Technology, talks about a recent Science Robotics paper on the case against machine vision for the control of wearable robotics. It turns out the costs of adding video cameras to exoskeletons—such as loss of privacy—may outweigh the benefits of having robotic helpers on our arms and legs.  This week’s episode was produced with help from Podigy. About the Science Podcast Authors: Sarah Crespi; Christa Lesté-Lasserre; David Malakoff Learn more about your ad choices.

First up this week, Staff Writer Paul Voosen joins host Sarah Crespi to discuss mapping clogs and flows in Earth’s middle layer—the mantle. They also talk about recent policy stories on NASA’s reactions to President Donald Trump’s administration’s executive orders. Next, the mantis shrimp is famous for its powerful club, a biological hammer it uses to crack open hard shells. The club applies immense force on impact, but how does it keep itself together blow after blow? Nicolas Alderete is an associate researcher at the National Institute of Standards and Technology, but at the time of the work he was a graduate researcher in theoretical and applied mechanics at Northwestern University. He joins the podcast to discuss the makeup of the mantis shrimp’s club and how it uses “phononics”—specialized microstructures that can reduce or change high-frequency vibrations—to reduce wear and tear when smashing and bashing. This week’s episode was produced with help from Podigy. About the Science Podcast Authors: Sarah Crespi; Paul Voosen Learn more about your ad choices.
