Scientific evidence that cats are liquids, and when ants started their fungus farms Oct 03, 2024

Show notes

First up this week, online editor David Grimm joins host Sarah Crespi to talk about how cats think about their own bodies. Do cats think of themselves as a liquid, as much the internet appears to believe? New experiments suggest they may—but only in one dimension.

Next, freelance producer Ariana Remmel is joined by Ted Schultz, a research entomologist at the Smithsonian Institution, to discuss the evolution of ant-fungus farming. It turns out, ants and fungus got together when the earth was going through some really tough times around 66 million years ago.

Burying trees to lock up carbon, notorious ‘Alzheimer’s gene’ fuels hope, and a book on virtual twins Sep 26, 2024

Show notes

The gene variant APOE4 is finally giving up some of its secrets, how putting dead trees underground could make carbon sequestration cheap and scalable, and the latest in our series of books on an optimistic future

First up this week, Staff Writer and Editor Jocelyn Kaiser joins host Sarah Crespi to discuss APOE4, a gene linked with a higher risk of Alzheimer’s disease. They talk about new research into why APOE4 might be a good target for preventing or treating this dreaded neurodegenerative disease.

Next, Ning Zeng, a professor in the Department of Atmospheric & Oceanic Science and at the Earth System Science Interdisciplinary Center at the University of Maryland, joins the show to discuss an unusual approach to carbon sequestration and a very old piece of wood. He talks about how an unearthed 3000-year-old log that has held on to most of its carbon is pretty good proof that we can efficiently put carbon underground at low cost by burying trees.

Finally, we have the latest in our series of books on a future to look forward to. Books host Angela Saini talks with Peter Coveney and Roger Highfield, the two authors of the book Virtual You: How Building Your Digital Twin Will Revolutionize Medicine and Change Your Life.

Next, what does it feel like to be a rat? This week Science has a special issue on rats, focusing on their contributions to science, their history as invasives and disease carriers, and more. But Inbal Ben-Ami Bartal, a professor in the School of Psychological Sciences and the Sagol School of Neuroscience at Tel Aviv University, is here to talk about their capacity for empathy and other positive emotions.

In a sponsored segment from the Science/AAAS Custom Publishing Office, Erika Berg, director and senior editor of custom publishing, interviews University of Manchester professor Sarah Haigh about the past, present, and future of graphene. This segment is sponsored by Zeiss.

Hail finally gets its scientific due, and busting up tumors with ultrasound Sep 12, 2024

Show notes

Why don’t we know what is happening with hail? It’s extremely destructive and costs billions of dollars in property damage every year. We aren’t great at predicting hailstorms and don’t know much about how climate change will affect them, but scientists are working to change that. News Intern Hannah Richter joins host Sarah Crespi to discuss deploying new technologies in this long-neglected area of research.

Next on the show, ultrasound—it’s not just for looking inside the body anymore. Meaghan O’Reilly is a senior scientist in physical sciences at the Sunnybrook Research Institute, an associate professor of medical biophysics at the University of Toronto, and is the Canada Research Chair in biomedical ultrasound. She talks about how researchers are using focused sound waves to disrupt tumors, change the permeability of the blood-brain barrier, stimulate the immune system, and more.

Linking long lives with smart brains, and India’s science education is leaning into its history and traditions—but at what cost? Sep 05, 2024

Show notes

The latest in our series on global equity in science, and how better memory helps chickadees live longer

First up this week, as part of our series on global equity in science, Contributing Correspondent Vaishnavi Chandrashekhar joins host Sarah Crespi to talk about an initiative in India intended to increase education about early “Indian knowledge systems” amid concerns about homogenization and misinformation.

Next, producer Kevin McLean climbs a mountain to visit a test bed for intelligence. He met up with Joe Welklin and Vladimir Pravosudov of the University of Nevada, Reno to talk about their research on how memory helps mountain chickadees survive.

A fungus-driven robot, counting snow crabs, and a book on climate capitalism Aug 29, 2024

Show notes

First up this week on the podcast, the latest conservation news with Staff Writer Erik Stokstad. Stokstad and host Sarah Crespi talk about the fate of snow crabs in the Bering Sea, how much we have been overestimating fishing stocks worldwide, and invasive snakes in Guam that bite off more than they can chew.

Next, a fungus takes the wheel. Anand Mishra, a research associate in the department of mechanical and aerospace engineering at Cornell University, discusses a method of integrating electronics with fungal cells in a biohybrid robot. By using the hardy cells from a mushroom instead of the delicate cells of an animal, Mishra and colleagues hope to durably introduce the sensing and signaling capacity of these living organisms into robots.

Finally, the fourth installment of our six-part series on books that look to an optimistic future. This month, host Angela Saini talks with science writer Akshat Rathi about how capitalism might just save us from climate change and his book Climate Capitalism: Winning the Race to Zero Emissions and Solving the Crisis of Our Age.

Saving wildlife with AI, and randomized trials go remote Aug 22, 2024

Show notes

First up this week on the show, uncounted kilometers of fences are strung across the globe. Researchers know they interfere with wildlife migrations and sometimes make finding food and safety difficult for animals. But they don’t know where all these fences are. Freelancer science journalist Christine Peterson joins host Sarah Crespi to discuss how artificial intelligence and aerial photos could help create fence inventories and eventually reopen spaces for native species.

Next, Azizi Seixas, interim chair of the University of Miami Miller School of Medicine’s department of informatics and health data science and a professor in the department of psychiatry and behavioral sciences, discusses his review on decentralized randomized trials. Randomized, controlled trials based in a research center or centers have long been the gold standard for determining the effectiveness of a medical intervention. This week on the podcast, Seixas argues that distributed research designs with home-based measurements and reporting have the potential to speed up research, allow greater participation, and make the results of studies more equitable.

The humidity vs. heat debate, and studying the lifetime impacts of famine Aug 08, 2024

Show notes

Researchers debate if humidity makes heat more deadly, and finding excess diabetes cases in Ukrainian people that were born right after the 1930s famine

First up this week, which is worse: the heat or the humidity? Staff writer Meredith Wadman joins host Sarah Crespi to talk about conflicting reports on the risk of increased mortality when humidity compounds heat, and how to resolve the debate in the field.

Next, LH Lumey, a professor of epidemiology at the Columbia University Medical Center, discusses what the catastrophe of a famine can teach us about the importance of maternal and fetal health for the long term. His work focuses on records of a 1930s Ukrainian famine painstakingly reconstructed by Ukrainian demographers after being obscured by the former Soviet Union. The famine records combined with newer data show that babies gestated during famine are more likely to acquire type 2 diabetes later in life.

Iron-toothed dragons, and improving electron microscopy Aug 01, 2024

Show notes

First up this week, we hear about caves on the Moon, a shake-up at Pompeii, and the iron-lined teeth of the Komodo dragon. Reporter Phie Jacobs joins host Sarah Crespi to discuss these news stories and more from our daily newsletter, ScienceAdviser.

Next on the show, electron microscopes allow us to view a world inaccessible to light—at incredible resolution and tiny scales. But bombarding samples with a beam of electrons has downsides. The high-energy electrons used for visualizing minute structures can cause damage to certain materials. Jonathan Peters, a research fellow in the School of Physics at Trinity College Dublin, joins the podcast to talk about a new approach that protects samples while keeping resolution sharp.
