Stereo Chemistry

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 molecules. In this episode of C&EN Uncovered, reporter Britt Erickson explores the technologies behind these companies and the competition among them.

C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories. Check out Britt’s cover story on the destruction techniques for these “forever chemicals” at cenm.ag/foreverchemicals.

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 some people are calling a golden age. In this episode of C&EN Uncovered, reporter Laura Howes explains this exciting field of research and its implications for the drugs of the future.

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 are critical for green technologies like batteries. But these nodules are also an important part of ecosystems we are just beginning to understand. In this episode, C&EN reporter Priyanka Runwal chats with host Craig Bettenhausen about this complex issue.

The Nobel Prize announcements are big events at Chemical & Engineering News. But we find out the winners at the same time as everyone else. 

Then, the race is on for our reporters. 

This year, staffers Laurel Oldach and Mitch Jacoby took on the task of covering the science prizes. In this episode, they reflect on this year’s winning research in chemistry and medicine and share what it’s like covering the most prestigious prizes in science.

The first issue of C&EN was published in 1923 with the stated purpose of “the promotion of research, the development of the chemical industry, and the welfare of the chemist.” 

The world of chemistry has grown a lot since then, and the magazine has been there to report on it all.

To celebrate our 100th anniversary, C&EN reporter and informal historian Alex Tullo has sifted through thousands of issues of the magazine, and in this episode, he guides our host Craig Bettenhausen on a tour through the magazine’s history from the industrialization of plastics, to the environmental movement, to the modern era of digital publication. 

When this episode was recorded, Tullo was preparing the From the Archives feature for the 1980s, which is now published.

C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories. Read Alex’s entire series about the C&EN archives at cenm.ag/fromthearchives.
