Most fish die by slowly suffocating to death on the deck of a boat, struggling for air. That’s horrendously cruel, but it also makes for acidic, rubbery, smelly fish. There’s another way: ikejime, a Japanese method of fish slaughter where the fish is stabbed in the skull and dies instantly with a minimum of pain. That’s good for the animals — and, our guest Andrew Tsui argues, it makes for much tastier food. ––– Further reading: Cat Ferguson’s feature in Topic on Andrew Tsui and ikejime Ferris Jabr reviews the evidence that fish feel pain in Hakai Magazine Ikejime demonstrated by a chef at Go, a Japanese sushi restaurant in Beverly Hills More of Vox’s effective altruism coverage ––– Discover more podcasts from Vox here.  Learn more about your ad choices.

When volcanoes erupt, they spray particles into the atmosphere that cool the planet for a bit. As we get closer and closer to truly catastrophic global warming, more and more scientists are wondering whether a similar approach, called solar geoengineering, could be necessary. If it works, solar geoengineering could buy us some time to cut emissions and get our act together. If it doesn’t, the climate could be irreparably disrupted. No pressure. ––– Further reading: Brad Plumer explains the basics of geoengineering at Vox Umair Irfan walks through a new study on the limits of geoengineering The Stratospheric Controlled Perturbation Experiment, led by Harvard professor Frank Keutsch, seeks to learn more about the likely effects of solar geoengineering without actually doing it Gernot Wagner and his colleague David Keith make the cautious case for taking solar geoengineering seriously in the Wall Street Journal More of Vox’s effective altruism coverage ––– Discover more podcasts from Vox here.  Learn more about your ad choices.

Lithium is a potent drug used to treat bipolar disorder, but it’s also the third element in the periodic table, and you can find tiny amounts in most drinking water. Scientists have discovered something remarkable: In areas where the tap water has more lithium, fewer people seem to die by suicide. That raises a big question: Should we put small amounts of lithium in the drinking water? Can we afford not to? ––– Further reading: Anna Fels’s op-ed “Should We All Take a Bit of Lithium?” in the New York Times Nassir Ghaemi and colleagues review the evidence on trace lithium and suicide, homicide, crime, and dementia A recent study casting doubt on the trace lithium/suicide prevention link Jesse Hicks explains the fluoride controversy for the Science History Institute Jesse Hicks explains trace lithium, for Vice More of Vox’s effective altruism coverage ––– Discover more podcasts from Vox here.  Learn more about your ad choices.

Karianne Jackson was working for the North Dakota prison system in 2015 when a trip to Norway changed her life. There, she saw a prison with no bars and no uniformed guards. Instead, prisoners lived in small cottages with common areas, private bedrooms, even kitchens with real cups, real dishes, and real knives. And she started thinking: What if I could make the US prison system a bit more like that? ––– Further reading: Jessica Benko in the New York Times on the "radical humaneness" of Norway's Halden Prison Dashka Slater in Mother Jones on Karianne Jackson's "Norway experiment" in North Dakota Vox’s German Lopez explains mass incarceration in the United States More of Vox’s effective altruism coverage ––– Discover more podcasts from Vox here.  Learn more about your ad choices.
