I got a new preprint out talking about the impact of heatwaves (and warming in general) on the sediment biogeochemistry of temperate estuaries. Short version: it may contribute to eutrophication.

Interesting #preprint on automated reference-checking.
It "runs entirely on [one] machine (free public databases, a single consumer GPU, and open-weights models) with no [...] external services. The pipeline verifies that references exist, checks retraction status, compares metadata against canonical records, downloads and parses cited papers, verifies that they support the claims made about them, and [...] checks cited papers' own bibliographies. "
I gather they've finally taken this measure because of the preponderance AI-generated slop, but with any luck these other issues will improve too. The arXiv press release states “Review/survey articles or position papers submitted to arXiv without this documentation will be likely to be rejected and not appear on arXiv” so it does sound like they are acknowledging the other problems and intend to enforce their rules more strictly in the future.
"arXiv says it will no longer accept Computer Science papers that are still under review due to the wave of AI-generated ones it has received."
