Sports Happen So Much — the FSPI index, the basis-trade widget factory, and the insider-trading continuum
Matt Levine's July 23 column, diagrammed: FutureSports turning box scores into a continuous 7,500-based index (and why a continuous number is a better ETF wrapper than a binary bet), the Treasury basis trade getting squeezed on all three sides of the widget-factory model, the Truth API sitting on the unmarked line between journalism and insider trading, and Anthropic considering firm-wide 10b5-1 plans because its MNPI is model capability, not quarterly earnings.

SpatialDINO: Self-Supervised Learning for 3D Vision Transformers
Arkash Jain et al. (Kirchhausen Lab, Harvard Medical School)
A 3D self-supervised vision transformer for label-free segmentation and tracking of subcellular dynamics in lattice light-sheet microscopy (LLSM). Beat a prior approach co-led by Nobel laureate Eric Betzig on downstream subcellular structure prediction.
