Aerosols are very small, have a high surface to volume ratio and can readily reach super saturation. This combination makes them a unique environment for chemical reactions. We had a paper published in JACS that looked into the rate of chemical reactions within and on aerosols.

👏 Heroic effort to extract a H₂ record from ice cores 👏

The samples had to measured in the field immediately after drilling (i.e. fresh out the oven 🥮) to prevent the tiny H₂ molecules from leaking out.

Having a great day at JAMSTEC, visiting the Earth Surface System division. Their lobby has former versions of the Earth Simulator computer (currently at version 4) and, nerd that I am, here is a photo. JAMSTEC also lead work on LLM for climate adaption planning - essopenarchive.org/users/555101...

Major AI conference flooded with peer reviews written fully by AI Controversy has erupted after 21% of manuscript reviews for an international AI conference were found to be generated by artificial intelligence.

Bit late with this one, and paywalled. Fascinating to see AI tool concluding >20% of peer-reviews for ICLR are wholly AI-generated. Wait to see if there was a strong difference between the conclusions of the reviews, although it does flag some egregiously bad cases. www.nature.com/articles/d41...
