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.

Folge vom 23.11.2023Exascale supercomputers amp up science, finally growing dolomite in the lab, and origins of patriarchyA leap in supercomputing is a leap for science, cracking the dolomite problem, and a book on where patriarchy came from First up on this week’s show, bigger supercomputers help make superscience. Staff Writer Robert F. Service joins host Sarah Crespi to discuss how the first exascale computer is enabling big leaps in scientists’ models of the world. Next, producer Meagan Cantwell talks with the University of Michigan’s Wenhao Sun, professor of materials science and engineering, and graduate student Joonsoo Kim. They discuss solving the centuries-old problem of growing the common mineral dolomite in the lab. Finally, books host Angela Saini is back but this time she’s in the hot seat talking about her own book, The Patriarchs: The Origins of Inequality. Science Books Editor Valerie Thompson and host Sarah Crespi chat with Angela about what history, archaeology, and biology reveal about where and when patriarchy started.

Folge vom 16.11.2023AI improves weather prediction, and cutting emissions from landfillsWhat it means that artificial intelligence can now forecast the weather like a supercomputer, and measuring methane emissions from municipal waste First up on this week’s show, Staff Writer Paul Voosen joins host Sarah Crespi to talk about how artificial intelligence has become shockingly good at forecasting the weather while using way fewer resources than other modeling systems. Read a related Science paper. Next, focusing on municipal solid waste—landfills, compost centers, garbage dumps—may offer a potentially straightforward path to lower carbon emissions. Zheng Xuan Hoy, a recent graduate from the new energy science and engineering department at Xiamen University Malaysia, discusses his Science paper on this overlooked source of methane and some plausible solutions for reducing these emissions.

Folge vom 09.11.2023The state of Russian science, and improving implantable bioelectronicsFirst up on this week’s show: the future of science in Russia. We hear about how the country’s scientists are split into two big groups: those that left Russia after the invasion of Ukraine and those that stayed behind. Freelance journalist Olga Dobrovidova talks with host Sarah Crespi about why so many have left, and the situation for those who remain. Next on the show: miniature, battery-free bioelectronics. Jacob Robinson, a professor in the department of electrical and computer engineering at Rice University, discusses how medical implants could go battery-free by harvesting energy from the human body and many other potential innovations in store for these internal medical devices.
