The bone and joint structures in mammal tails help them keep their balance. Could those benefits be adapted for robots? And, in her first children’s book, conservationist Bindi Irwin takes little readers on a journey through Australia Zoo.In Search Of The Best Tail For BalanceIf you have met a cat, you’ve probably at some point been amazed by how acrobatic they are. They’re able to reorient themselves effortlessly, even in midair. It turns out that a lot of that twistiness comes down to having a top-tier tail. While most reptile tails can swing only in one plane of movement, mammal tails have more joints, leading to better inertial control. That lets mammals tweak their balance better, much as holding a balance pole can help an acrobat navigate a tightrope.In a recent study published in the Journal of the Royal Society Interface, researchers explored the biomechanics of different tails, and considered how a better tail could help build a better robot. Dr. Talia Moore, a roboticist at the University of Michigan, and Dr. Ceri Weber, a cellular and developmental biology postdoc at UC San Diego, join Host Flora Lichtman to talk tails.Bindi Irwin Encourages Kids To Become ‘Wildlife Warriors’Almost 30 years ago, conservationists Terri Irwin and the late Steve Irwin captured the world’s attention with their show “The Crocodile Hunter.” It introduced millions of people to Australia Zoo and the strange, often scary, sometimes cute, critters from Down Under.Now, Terri and her children—Bindi and Robert—are at the helm of the zoo, which is the setting for Bindi’s new children’s book, You Are a Wildlife Warrior!: Saving Animals & the Planet. In it, Bindi takes little readers and her own daughter, Grace, on an adventure through the zoo.Host Flora Lichtman talks with Bindi about her family’s legacy, how motherhood fuels her approach to conservation, and what it’s like to run a zoo.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Pancreatic cancer is notoriously difficult to treat, and about 90% of diagnosed patients die from the disease. A team at Memorial Sloan Kettering has been working to improve those outcomes by developing a new mRNA vaccine for pancreatic cancer.A few years ago, the team embarked on a small trial to test the vaccine’s safety. Sixteen patients with pancreatic cancer received it, and even though it was a small study, the results were promising: Half the participants had an immune response, and in those patients the cancer hadn’t relapsed after 18 months.This week, the team released a new study in Nature following those same patients, and found six out of eight who responded to the vaccine in the first study did not have their cancer return more than three years later.Joining host Flora Lichtman to talk about these results, and what they could mean for the future of cancer treatment, is study author and surgeon Dr. Vinod Balachandran, director of The Olayan Center for Cancer Vaccines at Memorial Sloan Kettering, based in New York City.Transcripts for each segment will be available after the show airs on sciencefriday.com.  Subscribe to this podcast.

It’s been an unusually tough winter virus season. Rates of flu-like infections are higher than they’ve been in nearly 30 years. And for the first winter since the start of the COVID-19 pandemic, flu deaths have surpassed COVID deaths. Add to that a higher-than-average year for norovirus, a nasty type of stomach bug.Then there’s the emerging threat of avian flu. While there is no evidence of human-to-human transmission of the virus, about 70 people in the US have contracted the virus from livestock since April 2024.To make sense of the latest viral trends, Host Flora Lichtman talks with Dr. Katelyn Jetelina, epidemiologist and author of the newsletter “Your Local Epidemiologist”; and Dr. Erica Shenoy, chief of infection control at Mass General Brigham hospital.Transcripts for each segment will be available after the show airs on sciencefriday.com.
