Absolutely star studded awards ceremony this morning - Welcome new AAAR Fellows Jesse Kroll @jessekroll.bsky.social and Pat Keady! AAAR Fellows make up 0.2% of the AAAR membership. They are recognized for their significant contributions to aerosol research and service to AAAR #AAAR2025

I love when you go coat shopping and you try one on and it practically becomes part of your body. It's rare when things fit well.

Refinery fires, other chemical disasters may no longer get safety investigations Because of the federal government shutdown and proposed budget, key federal investigations may stop, including into what happened at a Chevron refinery in California in October 2025.

The recent Chevron refinery fire highlights why we really need some of the agencies that have been, or that are being, shut down.

The Chemical Safety and Hazard Investigation Board (CSB) is one of many that help keep ourselves and our communities safe.

Monarch in purple flowers.

I need a little timeline cleanse. I love the colors of a monarch against a flower. It's so cool how two colors I wouldn't normally pair work so well together in nature.

I emailed it to you, let me know if you didn't receive it.

Oh cool, I didn't realize it kept them in the folders! I'll have to play with that 😀

That makes sense, I use tags and folders but I can see that being a faster method.

Semi-random question. Every now and then I accidentally archive an email in Gmail. I know how to undo this, but I don't understand that feature. Does anyone use that archiving on purpose? I'm trying to figure out how it could be helpful.

I am able to sponsor postdoctoral fellows through this program!

PhD Position in Atmospheric Chemistry

We have a new PhD project to study ozone formation from fires. If interested in atmospheric chemistry, fires, living in Zurich, and studying at ETH, consider applying here: jobs.ethz.ch/job/view/JOP...

If you know folks that were impacted by the eligibility changes to the #GRFP last week, please consider signing/sharing this urgent petition to restore eligibility! 🙏

NSF Graduate Research Fellowship Program (GRFP)

So they finally posted the GRFP info. The big news I see is that it's now closed to second years.

This really sucks for students rotating to find a lab in their first year. IMO a year's warning would have been more appropriate.

As a geologist with some experience working with biologists, one of my favorite things is when they refer to certain snails as "terrestrial snails." I know this is to distinguish them from aquatic snails but it also implies the existence of extraterrestrial snails, which I am 100% in favor of.

Re-Examining Chemical Conditions of Past Chamber Studies of Secondary Organic Aerosol Formation The simulation of secondary organic aerosol (SOA) in 3D models generally relies on measurements made in laboratory chamber studies. However, many of the laboratory studies that underpin the aerosol pa...

Our paper examining the chemical conditions of past chamber studies is out! This work explores assumptions made when creating SOA parametrizations based on laboratory data, and can hopefully point to ways of improving model representation of SOA.

Chemicals "stick" to surfaces in houses, to a greater degree than some might expect. This is why you smell the popcorn you burnt long after you might expect it to vent from the house.

This story is so cool, especially the thermogenesis. I had no idea a plant could reach those types of temperatures!

Man, I've thought about this more and I really can't see a way to justify even the mildest things they are doing. How the hell did it get so far?!

Thank you!!

Hi Manu,

Can you please add me to the atmospheric feed? I work in indoor and outdoor atmospheric chemistry.

Thank you!!

Living a moral life in an age of bullies requires collective action; it cannot be done alone. Each of us must organize and participate in a vast network of moral resistance. From this solidarity we will grow stronger. This is what our current moment requires.

Yeah. I think a lot of people aren't trained to "pay attention to what they do, not what they say".

For the broader public: I guess if you believe the lies, then the actions could seem justified. I have to go deeep down a mental rabbit hole to see it though.

I think they are too small minded to see a new better future, so they are trying to recreate the parts of the past they liked through memos and threats. If they actually wanted to build what they say they want - they'd put funding into education, health, research/development, and infrastructure.

My first NASA position, as a contractor in the Kepler Science Office, was on a H-1b visa. NASA ended up giving me a medal and now I’m the Chief Scientist of NASA Exoplanet Science Institute and an American citizen to boot. Seems like a net win for the US, no? But now this:
