Existing tools force a tradeoff: bin the data into voxels to align it like an image, which erases single-cell resolution, or align sparse point sets while ignoring the functional signal entirely. DET treats the data as a function on an irregular domain, using a Bayesian model where the deformation between samples is driven by both geometry and gene-expression values. It's fully unsupervised and scales to large datasets by registering a sample of points, then interpolating the deformation across the rest.\n\nOn a 90-case MERFISH mouse-brain benchmark with heavy perturbations and no initial alignment, DET produced the best spatial overlap and tissue topology among the pipelines tested. A modified version of a rival tool, PASTE2, still won on a separate accuracy measure called label-transfer ARI, so no single method swept every metric.\n\nThe team's own atlas-scale mouse-embryo test had no cross-stage ground truth to check against, so those gains are self-referential rather than proof the alignment matches actual biology, a caveat worth remembering before anyone calls this settled.","[\"spatial-transcriptomics\",\"bayesian-statistics\",\"bioinformatics\",\"registration-algorithms\"]","2026-09-18T04:00:00.000Z","2026-09-19T07:47:56.691Z","2026-09-19T07:48:08.612Z","published",null,[],"science",[26,27,28,29],"spatial-transcriptomics","bayesian-statistics","bioinformatics","registration-algorithms",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2603.21235",0,{"sections":36},[37,42,47,52,57,62,66,71,75,80,85,90,95,100],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",4114,"2026-09-19T18:33:46.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",673,"2026-09-19T17:30:00.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":51},"Policy","policy",345,"2026-09-19T19:22:20.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":58,"slug":59,"count":60,"latest_published_at":61},"Hardware","hardware",156,"2026-09-19T11:00:00.000Z",{"name":63,"slug":24,"count":64,"latest_published_at":65},"Science",129,"2026-09-19T19:45:00.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":18},"Dev Tools","dev-tools",78,{"name":76,"slug":77,"count":78,"latest_published_at":79},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",42,"2026-09-18T22:35:10.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
