Per- and polyfluoroalkyl substances, a class of chemicals known as PFAS, are often called “forever chemicals” because of how long they persist in the environment. They are prevalent in drinking water and have been linked to negative health outcomes. A slew of cleantech start-ups are cropping up with the aim of breaking down and destroying PFAS mole…

As the science of drug discovery has grown in scale and gotten more complicated, so have the drug molecules themselves. But there’s a promising class of drugs made of just a handful of atoms that punch above their weight by leveraging the natural chemistry of the cell. Recent discoveries have opened up a new era of pharmaceutical chemistry that som…

Resting on the bottom of the ocean are potato-sized nodules of valuable minerals that are more or less up for grabs. Multiple corporations and some nations are racing to build deep-sea drones that can withstand the extreme conditions at the seafloor and bring these 1-20 cm nodules to eager buyers on the surface. Many of the metals in these nodules …

Lithium iron phosphate (LFP) batteries are cheaper, safer, and longer lasting than batteries made with nickel- and cobalt-based cathodes. In China, the streets are full of electric vehicles using this technology. But LFP never caught on as a chemistry for electric vehicle batteries in North America. In this episode, C&EN reporters Craig Bettenhause…

Researchers reported finding microplastics in drinking water nearly 5 years ago, prompting California lawmakers to require monitoring of the state’s drinking water for the tiny particles. But in 2018, there were no standard methods for analyzing microplastics. So California regulators reached out to chemists and toxicologists from all sectors to de…

This month, Stereo Chemistry is sharing an episode of the podcast Tiny Matters that examines that question. In the episode, hosts Sam Jones and Deboki Ch…

Chemists may know James Harris as the first Black scientist to be credited with codiscovering an element. In fact, we referenced this in a previous episode of Stereo Chemistry about making superheavy elements. But beyond this memorable factoid, details about the accomplished nuclear chemist are scarce, and most sources repeat the same superficial i…

Helium shortages can derail research and threaten expensive instruments that depend on the gas to operate safely. In late 2020, analysts predicted—and we reported—that pressures on the global helium market were likely to ease as new production capacity came online.
