First up this week, we celebrate 20 years of graphene—from discovery, to hype, and now reality as it finally finds its place in technology and science. Science journalist Mark Peplow joins host Sarah Crespi to discuss graphene’s bumpy journey.   Next, producer Meagan Cantwell talks with Seth Darling, chief science and technology officer for the Advanced Energy Technologies Directorate at Argonne National Laboratory, about two new ways to harvest lithium from water. One approach harnesses sunlight to pull water up through a membrane and collect lithium, whereas the other uses an electrochemical cell to selectively suck lithium up. Finding efficient ways to extract lithium from sources where it’s lower in concentration, such as the ocean, will be crucial as demand increases.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Meagan Cantwell; Mark Peplow   Episode page: https://www.science.org/doi/10.1126/science.zn17zjt Learn more about your ad choices.

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.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Ariana Remmel; David Grimm Episode page: https://www.science.org/doi/10.1126/science.zlav1o2 Learn more about your ad choices.

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.   This week’s episode was produced with help from Podigy.   About the Science Podcast Episode page: https://www.science.org/doi/10.1126/science.z8oerdq   Authors: Sarah Crespi; Jocelyn Kaiser; Angela Saini Learn more about your ad choices.
