Basic geoengineering, and autonomous construction robots
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...

AI improves weather prediction, and cutting emissions from landfills
What 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 s...

The state of Russian science, and improving implantable bioelectronics
First 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 oth...

Turning anemones into coral, and the future of psychiatric drugs
Why scientists are trying to make anemones act like corals, and why it’s so hard to make pharmaceuticals for brain diseases First up on this week’s show, coaxing anemones to make rocks. Newsletter Editor Christie Wilcox joins host Sarah Crespi to discuss the difficulties of raising coral in the lab and a research group that’s instead trying to pin down the process of biomineralization by inserting coral genes into easy-to-maintain anemones. Next on the show, a look at why therapeutics for both neurodegenerative disease and psychiatric illness are lagging behind other kinds of medicines. Steve Hyman, director of the...

Making corn shorter, and a book on finding India ’s women in science
First up on this week’s show, Staff Writer Erik Stokstad joins host Sarah Crespi to talk about why it might make sense to grow shorter corn. It turns out the towering corn typically grown today is more likely to blow over in strong winds and can’t be planted very densely. Now, seedmakers are testing out new ways to make corn short through conventional breeding and transgenic techniques in the hopes of increasing yields. Next up on the show, the last in our series of books on sex and gender with Books Host Angela Saini. In this installment, Angela speaks with Nandita Jayaraj and Aashima Dogra about their book Lab Hoppi...

The consequences of the world's largest dam removal, and building a quantum computer using sound waves
Restoring land after dam removal, and phonons as a basis for quantum computing First up on this week’s show, planting in the silty soil left behind after a dam is removed and reservoirs recede. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about the world's largest dam removal project and what ecologists are doing to revegetate 36 kilometers of new river edge. Next up on the show, freelance producer and former guest Tanya Roussy. She talks with Andrew Cleland, a professor at the University of Chicago, about a Science paper from this summer on using the phonon—a quantum of sound energy...
