Despite not having a known function, cellular “vaults” are on the verge of being harnessed for all kinds of applications, and looking at the evolution of brown fat into a heat-generating organ   First on this week’s show, Managing News Editor John Travis joins host Sarah Crespi to discuss mysterious cellular complexes called “vaults.” First discovered in the 1980s, scientists have yet to uncover the function of these large, common, hollow structures. But now some researchers are looking to use vaults to deliver cancer drugs and viruses for gene therapy.   Next, what can we learn about the evolution of brown fat from opossums? Unlike white fat, which stores energy in many mammals, brown fat cells use ATP to generate heat, helping babies maintain their body temperature and hibernators kick-start their summers. Susanne Keipert, a researcher in the Department of Molecular Biosciences at Stockholm University’s Wenner-Gren Institute, talks about when in evolutionary history brown fat took on this job of burning energy.   Finally, this week we are launching our music refresh! If you are interested in what happened to our music—where it came from and how it’s different (and the same)—stay tuned for a chat with artist Nguyên Khôi Nguyễn.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; John Travis  Episode page: https://www.science.org/doi/10.1126/science.zpoy92t Learn more about your ad choices.

Studying color vision in with children who gain sight later in life, joining a cancer trial doesn’t improve survival odds, and the first in our books series this year First on this week’s show, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the pros and cons of participating in clinical trials. Her story challenges the common thinking that participating in a trial is beneficial—even in the placebo group—for cancer patients.   Next, Lukas Vogelsang, a postdoctoral fellow in the department of brain and cognitive sciences at the Massachusetts Institute of Technology, talks about research into color vision with “late-sighted” kids. Studying children who were born blind and then later gained vision gave researchers new insights into how vision develops in babies and may even help train computers to see better.   Last up on the show is the first in our series of books podcasts on a future to look forward to. Books host Angela Saini talks with author Claire Horn, a researcher based at Dalhousie University’s Health Justice Institute. They discuss the implications of growing babies from fertilized egg to newborn infant—completely outside the body—and Horn’s book Eve: The Disobedient Future of Birth.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Angela Saini; Jennifer Couzin-Frankel   Episode page: https://www.science.org/doi/10.1126/science.z6gdgb4 Learn more about your ad choices.

A roundup of online news stories featuring animals, and researchers get crows to “count” to four   This week’s show is all animals all the time. First, Online News Editor Dave Grimm joins host Sarah Crespi to discuss stepping on venomous snakes for science, hunting ice age cave bears, and demolishing lizardlike buildings.   Next, producer Kevin McLean talks with Diana Liao, a postdoctoral researcher at the University of Tübingen, about teaching crows to count out loud. They discuss the complexity of this behavior and how, like the famous band, these counting corvids have all the right vocal skills to do it.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kevin McLean; David Grimm   Episode page: https://www.science.org/doi/10.1126/science.ztje4j6 Learn more about your ad choices.
