Interesting model-driven paper out of @jordonhemingway.bsky.social's group on the relative rates of pyrite burial and oxidation and how both relate to what's going on with organic carbon. 🧪⚒️

🚨 First #SEELab @eth-eaps.bsky.social PhD student-led paper is now officially online! We show that sedimentary conditions regulate formation rate and isotope composition of #pyrite, and that this process currently out-paces oxidation on land, leading to O2 accumulation

Former long-time resident of Somerville, can confirm an over-abundance of rats
Federal officials said they had arrested a visiting professor from Brazil at Harvard on Wednesday, weeks after he fired a pellet gun near a synagogue and officials accused him of antisemitism. The professor, who lived near the synagogue, said he was hunting rats nearby.

While Genossenschaften ("co-ops" in the article) are great, they are a low proportion of total housing and have extremely long wait lists and low turnover. Given how high rent is for the rest of us---and the frequency of demonstrations about the cost of living---id say no, we haven't solved it
The way that housing co-ops work in Switzerland may seem foreign to many. But the central idea is simple: What if homeownership had no profit motive and no capital gains? Advocates say their model could reshape how the world thinks about affordable housing. www.nytimes.com/2025/08/26/r...
