Whaaat?! The EPA's cost-benefit analysis of air pollution regulations can only consider costs to businesses but not health benefits?! This is nonsense. GIFT ARTICLE: www.nytimes.com/2026/01/12/c...

After reviewing nearly 200 applications from prospective grad students and postdocs over the past few months for a couple different 🧪⚒️ postings, here are some tips, at least as they apply to North American positions. I hope they help future applicants. Share with your networks. 🧵

Americans don't understand the big deal about electric kettles because we're on 120 VAC. Once we see how fast water boils at 230 VAC, there's no going back.

My last MIT student, Joe, explored what controls the ozone formed in fire plumes. His paper is out today in ACP. Happy Thanksgiving! acp.copernicus.org/articles/25/...

Another terrifying article about Stardust, with (what I think is) some new info: - they claim they'll finally release info on their secret particles starting in early 2026 - they plan a first atmospheric test in 2027 - they've been funding academic research (with one PI named)

I imagine that Brits trying to understand a fractured party system could look at Canadian political history. Though recent Canadian history might suggest that party consolidation (at least under FPTP) is inevitable. www.theguardian.com/commentisfre...

I regret to inform everyone that my pedantic brain couldn’t let me live until I knew whether or not dodger blue and blue jays blue are the same blue. They are ONE PANTONE NUMBER APART.

It’s okay, Jays. You’ll get ‘em in game four, which starts ten minutes from now.

Could a “smoke alarm” for airborne contaminants monitor and improve the quality of the air indoors? (Where Americans spend 90 percent of their time!) An interdisciplinary research team led by @linseymarr.bsky.social will create such a system that could cut respiratory illnesses by 25 percent. 👏

wikipedia's data shows that AI is siphoning traffic away from the site, which is a danger to its sustainability. ironically Wikipedia is more important than ever to users who want reliable information instead of slop, and to AI companies that need it for training data www.404media.co/wikipedia-sa...

"If we leave writing to AI chatbots, we won't just lose a craft and the skills. Because writing is more than that. Writing is thinking", argues Giorgio Iemmolo, Director of the Language Centre at ETH and the University of Zurich. ethz.ch/en/news-and-... What is your opinion?

184 years earlier than predicted, London has met the legal limits for toxic NO2 for the first time. This historic milestone proves that bold action like expanding ULEZ works, protecting children’s health and giving millions cleaner air to breathe.

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. pubs.acs.org/doi/full/10....
