The COVID-19 pandemic put the importance of indoor air quality in stark relief. The air in schools was of particular concern, and that concern spurred collaboration between researchers and school staff to find interventions to improve air quality to safeguard the health of students and staff. Data from indoor air monitors revealed that filter-based portable air cleaners were effective at removing airborne particulates. Ongoing research and monitoring will determine whether this effort is making a beneficial health impact and will be used to decide how to manage indoor air quality going forward. C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories. Check out the full story about air quality monitoring in schools at cenm.ag/airqualityinschools.   Cover photo: Undergraduate student Ricardo Reyes collects air quality measurements from the back of a classroom in Colorado.   Subscribe to Stereo Chemistry now on Apple Podcasts, Spotify, or wherever you listen to podcasts.   A transcript of this episode will be available soon at cen.acs.org.   Credits Executive producer: David Anderson C&EN Uncovered host: Craig Bettenhausen Reporter: Fionna Samuels Audio editor: Ted Woods Copyeditor: Brian Vickers Episode artwork: Glenn Asakawa/University of Colorado Boulder Music: “Hot Chocolate,” by Aves Contact Stereo Chemistry: Contact us on social media at @cenmag or email cenfeedback@acs.org.

On Oct. 9, the 2024 Nobel Prize for Chemistry was awarded to David Baker, Demis Hassabis, and John M. Jumper for their work in prediction and design of protein structures. C&EN’s executive editor for life sciences, Laura Howes, joins a special episode of Stereo Chemistry to discuss why the trio won, the significance of their work around proteins, and how she accurately predicted the win in C&EN’s annual “Who Will Win?” webinar. Stereo Chemistry offers a deeper look at subjects from recent stories pulled from the pages of Chemical & Engineering News. Check out Laura’s story on how these computational chemists won this year’s Nobel Prize in Chemistry at cenm.ag/chemnobel2024.  

In the 20th century, corporate powerhouses like Bell Labs and DuPont Central Research funded R&D from their balance sheets, creating a clear path for postdoctoral scientists to innovate beyond their university research. In 2024, with the decay of corporate laboratories, graduates are taking the commercial start-up route more and more. C&EN, business reporter Matt Blois discusses several such start-ups, exploring how the founders are making the transition from PhD to CEO and mapping the various routes they've taken to secure funding to continue their research. C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories.

On average, from 2011 to 2021, academic labs generated around 4,300 metric tons of hazardous waste each year. One of the largest lab-used solvents discarded is dichloromethane and more than half of that waste ends up burned. In today’s episode, policy reporters Krystal Vasquez and Leigh Krietsch Boerner dive into the processes academic labs use to dispose of said waste, the consequences of new EPA regulations around dichloromethane, and what solutions academic institutions are coming up with to accommodate these new rules. C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories. Check out Krystal’s story on the new U.S. Environmental Protection Agency regulations regarding dichloromethane at https://cenm.ag/dcmregs and check out Leigh’s story about solvent waste disposal in academic laboratories at https://cenm.ag/wastedisposal.

Tragedies in the communities of Flint, Michigan, and East Palestine, Ohio, continue to affect residents 10 years and 1 year on, respectively, from the initial events. Residents of both cities continue to rebound and rebuild despite ongoing issues revolving around the toxic chemicals that were introduced to their towns through human decisions. C&EN physical sciences reporter Priyanka Runwal traveled to both Flint and East Palestine to speak with residents about how they are recovering, how the actions of their representatives have fallen short, and their hopes to return to something of a “normal” existence in the future. C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers a deeper look at subjects from recent stories.
