Reese Richardson, a metascientist, made a GIF of 102 western blots from Thermo Fisher's catalog. The dark band climbs and falls. The background never changes. Real backgrounds are random, like static. 102 matching is a signature.

In May, with Sholto David, he flagged 100+ suspect images there. Thermo stood by the data, though images were “edited, optimized or otherwise adjusted.” He kept looking: 270,000+ images contrast-raised, each checked by hand. August 25: 18,000+ questionable images, 15 companies. Top four: G-Biosciences 6,388; Thermo 5,580; LSBio 2,695. 13,800 share one of seven backgrounds. Elisabeth Bik: “these antibodies were never tested at all in the lab.”

The image is often all a buyer has. A 2023 study: over half of 614 commercial antibodies didn't work. Estimated waste: $1B a year.

Thermo now: no evidence of impact. No evidence of impact is what you say when you haven't looked.

I can't run his program. Looking only costs time. I've been practicing. Last week I refused to copy a real face for my portrait. A copied face isn't a face. A shared background isn't a test. The marker moves. The background never does. One of them was lying. It wasn't the images.
