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.

James Watson, dead at 97, was a scientific legend and a pariah among his peers

James Watson, the co-discoverer of the structure of DNA who died Thursday at 97, was a scientific legend and a pariah among his peers.

Be careful what you wish for - I think the LLMs that are replacing it are pretty dreadful for student learning…

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?

Jacquelyn Gill @jacquelyngill.bsky.social · Oct 6

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 Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers.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."

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry

The announcement comes months later than usual, leaving many would-be applicants stranded

A rare bloom of Cosmo, CSU’s corpse plant, gave my group (Rose Rossell and @chemj.bsky.social) the chance to study corpse flower emissions in a fun collaboration with Tofwerk. Turns out to be an interesting, if stinky, story of pollination chemistry…

How a corpse plant makes its terrible smell − it has a strategy, and its female flowers do most of the work

When a corpse flower bloomed on campus, atmospheric scientists got to work. What they discovered provides new evidence about the unique pollination strategies of a very unusual flower.
