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.

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 Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers.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

New paper on what drives organic aerosol in NY - anthropogenic chemicals have emerged as 2x traffic sources, while wildfire smoke is persistent and substantial - and we see evidence that it enhances biogenic SOA.

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.

A rule of thumb for tsunamis is that in open ocean, they move at similar speeds to commercial airliners. If you're ever curious how long it would take for a tsunami to get from one place to another, look up the duration of a similar-length flight.
