Przewalski’s horses are truly wild horses, even the ones held in captivity. They traditionally roamed the Central Asian steppes, so you can imagine everyone’s surprise when two separate accounts on TikTok claimed to have found a Przewalski’s horse here in the U.S. But as guest and Scientific American associate news editor Allison Parshall will tell you, the real story is the remarkable conservation efforts that led to a resurgence for this horse, which was once considered extinct in the wild.The Last Wild Horses Are Finally Returning to Their Natural Habitat How a Cloned Ferret Inspired a DNA Bank for Endangered Species Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.

We’re looking at our reporting—from 100 years ago. In 1924 Scientific American’s pages were bemoaning traffic, waste management and pests. They were also praising the by-products of coal tar and those substances’ use in household items. While the record is clear on the toxicity of fossil fuels to our environment and our health, demand for fossil-fuel-based “petrochemical” products such as plastic is only increasing. Host Rachel Feltman advises on how to avoid petrochemicals in our everyday products. Plus, we take a lighthearted look at a telepathy study also featured in one of our 1924 issues. Recommended reading:The Gas Industry Is Gaslighting the Public about Climate ChangeRenewable Power Set to Surpass Coal Globally by 2025E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter. Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.

Microplastics are everywhere—and we mean everywhere. These pesky plastic pollutants have been found in penis tissue, testicles, breast milk and blood. They’ve turned up in Antarctic snow, in the clouds above Mount Fuji, inside deep-sea creatures and near the top of Mount Everest. In Paris Olympic ambitions for the Seine’s are being complicated by bacteria. Far above Earth, the Starliner spacecraft faced a rocky road to the International Space Station (ISS). Starliner’s return to Earth is being delayed as Boeing and NASA officials take a look at the leaks and thruster failures that occurred during its journey to the ISS.Recommended reading:Microplastics Linked to Heart Attack, Stroke and DeathThe Physics of Breakdancing, a New Olympic Sport E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter. Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Madison Goldberg and Jeff DelViscio.

All aboard the Nathaniel B. Palmer, a research vessel making its way through the waters of West Antarctica. Journalist Sofia Moutinho is joining a team of chemists trying to find out how glacial melting is changing ocean chemistry—and what those changes might mean for the global climate.The researchers want to know whether a negative feedback loop could take shape in Antarctica’s seas. Carbon dioxide contributes to the rise in warming that is melting the glaciers. As glacial melting releases iron, phytoplankton feast. Phytoplankton in turn remove carbon from the air, potentially causing a cooling effect.Stay tuned for next Friday’s episode, where Moutinho will embark on a hunt for sea ice and hear about the researchers’ special encounter with Adélie penguins.E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!Discover something new every day: subscribe to Scientific American and sign up for Today in Science, our daily newsletter. Science Quickly is produced by Rachel Feltman, Fonda Mwangi, Kelso Harper, Carin Leong, Madison Goldberg and Jeff DelViscio.
