A new study led by @swri.org provides evidence that liquid nitrogen is rising to Pluto’s surface through cracks in the northern edge of the Sputnik Planitia, part of the massive heart-shaped glacier on the dwarf planet’s surface. 🧪 🔭

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.

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...

Super pollutants are trendy, but we should be careful how we use them • Substituting short lived climate pollutants like methane for CO2 as carbon offsets risks breaking the math of net zero
