I usually love seeing my friends quoted in the NYTimes, but the reasons for @marinavance.bsky.social being the focus of this story are so sad. The damage to US science is terrible.

well… your skin lipids undergo ozonolysis pretty much continuously with ambient ozone, creating an array of ketones and aldehydes that you then breathe.

(Us indoor chemists can ruin anything. You’re welcome.)

Not quite the same, but as a grad student, I once ordered a cylinder of nitrogen oxide - or as I wrote it on the purchase order, “NO cylinder“. Cue much confusion about how I would get my calibration standard without a cylinder….

Thanks to Erica Hartmann for leading a newly published paper, "Ten questions concerning indoor dust."

What is it?
Where does it come from?
How does it mediate environmental exposures?
How does it affect chemicals indoors?

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

Hey Colorado residents, particularly people in Fort Collins, but also those who are somewhat near: my sister and brother in law are running a study on an easy, portable method to help maintain indoor air quality during adverse outside events (like smoke or pollution).

I think this explains what is going on with papers at JGR-Atmos - I have two stuck in reviewer purgatory for >90 days!?! Anyone else?

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

Spooky season approaches, so I'm going to repost some of my Halloween comics from years past.
A four panel comic called Happy Halloween From The Birds. In panel 1, a pileated woodpecker has pecked its huge gaping rectangular holes in a pumpkin. In panel 2, a yellow-bellied sapsucker has pecked a face using its standard rows of small holes. In panel 3, a satin bowerbird has carved a pumpkin into a bower and placed its favorite blue candies all around it. In panel 4, a loggerhead shrike has impaled mini pumpkins on a fence's metal spikes and is saying "fight me."

I do not want the video. I will never watch the video. I usually won’t even give the video the effort of complaint.

I just want to read the news story. Give me the text. This would be my Ted Talk but that would be text too.
