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

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 !

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/

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... Our writeup:

We had the opportunity today to visit the tower at the DOE AMF3 site at Bankhead National Forest. We need federal funding to enable resources like this to understand fundamental processes occurring on Earth.

Happy International Women's Day! A reminder that this specific screwup has now killed ~25 million people. A world that allows an influential, entitled, ignorant man to just shout down a smarter and more knowledgeable woman 👉can literally kill you.👈 www.wired.com/story/the-te...

The board of the Fulbright program appears to have entirely resigned, accusing the State Department of illegally canceling scholarships "based mainly on research topics": www.nytimes.com/2025/06/11/u...

What a humiliating defeat for former UMich president Santa Ono: "And I’m here to ensure that DEI never returns to the University of Florida," he said—today. And now:

AAAR has new travel grants for current/recent federal scientists and program managers and an updated job board coming soon. See below for a statement from the AAAR Executive Committee: @americanaerosol.bsky.social @vfmcneill.bsky.social @jessekroll.bsky.social @andrewpault.bsky.social

Northwestern has not received any NIH funds since March. No written communication about why or what can be done. Thank you Ben Singer for raising awareness at #ATS2025

Remarkable how batteries are transforming CAISO. If deployment quadrupled (challenging now with the tariffs), non-co2 emitting sources (solar + hydro + nuclear + wind + geothermal) could provide nearly 24 hours of carbon free electricity.

What's happening with these grants is much more complicated and mostly unknown. None of the NIH have been officially cancelled. The NIH was just ordered to stop paying. They got the Unis to enforce silence on their own campuses because they thought they were "negotiating" and cld get the funds back.

2/ Just as critically, numerous cancer cure research studies (along with various other diseases) are being killed in secret while making it hard for news to get out because nothing has officially been canceled. If you have a loved one with cancer, sorry.

The current administration’s narrative that Harvard (and all universities) feel “entitled” to federal dollars misleads the public. Nor are these funds a “privilege” 1/n

During my career NSF has been the glue holding US environmental science together. Like in other areas, it has carried fundamental research and been a model of rigorous and objective review that truly gives exciting ideas a fair chance. However, in this field it has also (1/2)

Early in the pandemic a colleague of mine and I wrote an urgent piece about counterfeit N95s being used by doctors and nurses. The counterfeits were coming from China. In the piece we reiterated that people should only be buying NIOSH-certified N95s. The program that certifies N95s was also canceled

Hearing now that every National Science Foundation grant is having to go through a new “DOGE review”. So existing grants and long term science and technology research having to undergo review by one of Elon’s interns. Huge percentage not passing their muster.

Some good news for a change–Queen's has set aside funds to assist any students who have lost their visa status in the US and are looking to continue their graduate studies. Please share widely. www.queensu.ca/grad-postdoc...

University of Michigan Regents come out squarely and publicly in defense of academic freedom against political coercion and the role of higher education and research in making America prosperous, secure ... and well ... maybe even Great? www.michigandaily.com/opinion/op-e...

This is a big deal. Spread the word. But it’s tiny compared to the totality of what’s happening at NIH. Cure Research for all cancers, Alzheimer’s, everything is being gutted. Intentionally. It’s all getting burned to the ground but the news isn’t getting out. The new cures won’t be there for you.

If you are interested in any aspects of research in aerosol particles: air quality, climate, health, atmospheric chemistry, airborne bacteria/viruses, I recommend following @americanaerosol.bsky.social This is a premier society for aerosol science in America!

An addition to this thread. Most of what people are hearing about today are job cuts and closures of various centers, institutes etc. But there’s another part of the ecosystem of cure research that Trump and Musk have been torching since January.

Just trying to get my head around the absolute gutting of cdc and nih today. A bleak day for the US and …. well staying alive longer than people did in the 19th century.

Breaking News: The EPA plans to eliminate its scientific research arm, firing as many as 1,155 chemists, biologists, toxicologists and other scientists.

You may remember #StayAtHomeChem from Twitter, selfies like this, me complain/bragging about pulling an all nighter to sample in my apartment...

I'm really thrilled this paper is out!! Led by @amfankhauser.bsky.social and @andrewpault.bsky.social, it gives results from an innovative field campaign: researchers sampled particles in their homes during COVID lockdown (guess which one is my old apartment...) pubs.rsc.org/en/Content/A...

Lemme share something with you. A lot of semi-Trumpy types are saying Zelensky blew it. All he had to do was show up, shake hands, say Trump is great and sign the docs. He couldn't do that. But there are also people in DC who are not Trumpy who are saying the same thing. Now, big picture this ...

Diversity is our greatest asset, even if the government disagrees… They not like us! POC in STEM are here to stay. They tried to rig the game but you can’t fake influence! Mustard on the [Be][At] bro. Happy Black History Month!

Elon acolytes targeting the National Oceanic and Atmospheric Administration. “It’s been a longtime goal of corporations that rely on Noaa data to prevent the agency from making the data public, instead of giving it directly to private corporations that create products based on it.”
