Top science from 2023, and a genetic tool for pangolin conservation   First up this week, it’s Science’s Breakthrough of the Year with producer Meagan Cantwell and News Editor Greg Miller. But before they get to the tippy-top science find, a few of this year’s runners-up. See all our end-of-year coverage here.   Next, Jen Tinsman, a forensic wildlife biologist at the U.S. Fish and Wildlife Service, joins host Sarah Crespi to discuss using genetics to track the illegal pangolin trade. These scaly little guys are the most trafficked mammals in the world, and researchers can now use DNA from their scales to find poaching hot spots.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Meagan Cantwell; Greg Miller   Episode page: https://www.science.org/doi/10.1126/science.zk0pw91   About the Science Podcast: https://www.science.org/content/page/about-science-podcast Learn more about your ad choices.

A look at cognition in livestock, and the coevolution of wild bird–human cooperation   This week we have two stories on thinking and learning in animals. First, Online News Editor David Grimm talks with host Sarah Crespi about a reporting trip to the Research Institute for Farm Animal Biology in northern Germany, where scientists are studying cognition in farm animals, including goats, cows, and pigs. And because freelance audio producer Kevin Caners went along, we have lots of sound from the trip—so prepare yourself for moos and more.   Voices in this story: Christian Nawroth Annkatrin Pahl Jan Langbein   Next, audio producer Katherine Irving talks with Claire Spottiswoode, an evolutionary biologist at the University of Cambridge, about her research into cooperation between honeyguide birds and human honey hunters. In their Science study, Spottiswoode and her team found honeyguides learn distinct signals made by honey hunters from different cultures suggesting that cultural coevolution has occurred.   Read a related Perspective.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; David Grimm; Katherine Irving   Episode page: https://www.science.org/doi/10.1126/science.zr3zfn1 Learn more about your ad choices.

Raising the pH of the ocean to reduce carbon in the air, and robots that can landscape   First up on this week’s show, Contributing Correspondent Warren Cornwall discusses research into making oceans more alkaline as a way to increase carbon capture and slow climate change. But there are a few open questions with this strategy: Could enough material be dumped in the ocean to slow climate change? Would mining that material release a lot of carbon? And, would either the mining or ocean changes have big impacts on ecosystems or human health?   Next, we hear from Ryan Luke Johns, a recent Ph.D. graduate from ETH Zürich, about why we want robots building big rocky structures from found materials: It reduces energy costs and waste associated with construction, and it would allow us to build things remotely on Mars.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Warren Cornwall   Episode page: https://www.science.org/doi/10.1126/science.z66mytn Learn more about your ad choices.
