Postdoc opening: airborne NH3 measurements

Join our team! The UMN atmospheric chemistry group is recruiting a postdoc to collect and analyze airborne NH3 measurements as part of NASA FarmFlux.

See z.umn.edu/aw67 for details, & contact Julieta (junco004@umn.edu) and I (dbm@umn.edu) with questions!

Longtime TPM reader and aerosol scientist, if I took one lesson from the past 5 years it is the importance of ventilation/dilution (i.e., cracking a window), amazing how quickly a sealed room fills (CO2, PM, etc.)

Try a CO2 monitor in your car with air recirculating (which is default for most cars when AC on), it is amazing to see how quickly it can hit >5,000. No wonder folks get so tired on long drives. As scientists studying indoor and outdoor air quality, we really need to get the word out better on this.

Plenary speaker Chris Hogan shares some eye-opening thoughts on the Knudsen number at 8 AM #AAAR2025

If the Supreme Court killed the Voting Rights Act by early January, Republicans in several Southern states would likely have enough time before the 2026 elections to re-gerrymander their congressional maps and target Black Democrats whose seats are currently protected by the VRA

Size Dependent Uncatalyzed Sulfite Oxidation in Aqueous Microdroplets Aqueous aerosols and microdroplets exhibit unique chemical kinetics relative to the bulk phase, impacting air quality and climate via multiphase atmospheric processes. Here, we investigate uncatalyzed...

Very happy to see this paper out! This has been a fun collaboration between @mcneill-lab.org and the Grassian group at UCSD. We are moving closer towards model representations of this intriguing size dependent microdroplet chemistry. Modeling by @sandhyasethuraman.bsky.social !

Very cool!

The Downballot's special elections Big Board for the 2025-26 cycle

A ton of effort goes into tracking special elections on our Big Board, so we're always grateful when people cite us by name and link us. This data—especially the presidential results, which we calculate by hand—doesn't grow on trees!

Ds now running 15.7 pts ahead of 2024. In 2017-18, it was D+10.6.

Today, the San Diego County Board of Supervisors proclaimed September 9, 2025, to be “Dr. Kimberly Prather and Dr. Paula Stigler Granados Day” in the County of San Diego. Supervisor and Scripps alumna Paloma Aguirre authored the proclamation. Congrats to @kprather.bsky.social and Paula!

Evidently this needs to be said:

Do not spray nitric acid into the air in the hopes of limiting viral transmission.

More pollution is not the solution. At all.

we could have wall to wall coverage of Trump's health. it could be the most important issue in the country right now, and not without decent reason. there could be wild speculation about his bruising and his public absences. there could be multiple front-page NYT stories.

but who is he, Joe Biden?

So the lab just got our first price quote with the Trump Tariffs included. Turns out that an increase in the cost of a scientific instrument by 39% (the tariff rate for Switzerland as of Aug 7) is…a lot of money! 1/

Iowa Democrats win massive upset to break GOP supermajority Catelin Drey's victory may portend more good news for Democrats next year

HUGE FLIP: Democrat Catelin Drey wins deep-red state Senate seat in Iowa, breaking the GOP's supermajority.

Drey won by 11 points in a district Donald Trump carried by 11 points last year. It's another massive overperformance. The Iowa GOP should be very worried for the midterms.

Our full writeup:

Catelin Drey crushed it tonight, winning by 55.2% to 44.8% in an Iowa Senate district that Trump carried by 11. Can't wait to dig into the precinct-level results.

@ZacharyOS.bsky.social and I will talk with the Democrat tomorrow.

We talk about it in our piece, but Catelin Drey ran on a very clear message: affordability and education. It's a message that works everywhere.

(The Republican, meanwhile, wanted to eliminate Iowa's income tax and replace it with ... nothing.)

One more special election tonight, for CA's conservative 63rd Assembly District. Results here: electionresults.sos.ca.gov/special/stat...
