The blood test that reads how DNA was torn

Make a test-bench plate: one experiment drawn as an instrumented rig, the apparatus in cutaway with its gauges and its readings, and the result stated in the headline. One still image, 1:1 square, briefed for a GPT Image 2 class model whose real ratio list is 1:1, 4:3, 3:4, 16:9, 9:16, 3:2 and 2:3. The discipline of this family is that the rig and the readout share one frame, so a stranger sees the thing being measured and the number coming out of it at the same time. FACT (locked, build on it, do not re-research): when cells in your body die, they shed short pieces of DNA into the bloodstream. These pieces are not cut at random. In a healthy person they come out at a characteristic length of about 167 base pairs, because that is the length of DNA wound around one nucleosome, the protein spool DNA is coiled on, plus the short linker between spools. Cancer cells have differently packed DNA, so they shred into a different and more disordered spread of lengths. A platform called DELFI, short for DNA Evaluation of Fragments for Early Interception, ignores what the DNA says and measures how it broke, comparing fragment sizes across the genome in large bins. On 31 July 2026 researchers at the Johns Hopkins Kimmel Cancer Center reported that this approach detected liver cancer in 2 populations that were biologically and geographically unlike each other. In Romania most participants had liver disease from viral hepatitis or alcohol. In Guatemala most had metabolic liver disease, obesity and diabetes, and many had been exposed to aflatoxin, a natural toxin from mould on stored crops that is linked to liver cancer. The test found the cancer in both. The team describe it as the first genome-wide fragmentation analysis independently validated in 2 separate high-risk populations with different causes of disease. Use these exactly and leave out any figure we have not locked. DO NOT PRINT AN ACCURACY FIGURE, a sensitivity, a specificity or a percentage, because we have not locked one and an invented one would be a real harm. Do not print a journal name. TONE, and this matters: this is a piece about a measurement being cleverer than expected, not a piece about illness. No patients, no hospital beds, no distress. The subject is the physics of how a molecule breaks. GROUND (decide this, do not let the model default): a deep ox-blood red field, saturated and flat, the red of a dried ink wash rather than a photograph of blood, filling the whole frame so the instrument sits inside a colour rather than on a page. White, pale grey and navy are the defaults this brief FAILS on, and so is clinical laboratory blue, a white bench under flat hospital light, and a glowing blue DNA helix on black. LIGHT: flat and even, the light of a technical plate, not a rendered studio. DISTANCE: the whole rig at arm's length, filling the frame, with one detail close enough that the fragments themselves have real edge. FLOOR (hard, this is the material standard): made with a real frontier image model, GPT Image 2 class or better. Flat vector, hand drawn SVG or HTML, and screenshot collage all FAIL. Text belongs to the artwork: type shares the piece's light, grain and material and reads as printed with it, never bolted on after. Archives will not be considered. CRAFT STANDARD (read all of it before you start). Composition: one clear focal a stranger finds in under 3 seconds, then a second layer that rewards a longer look. Legibility: this will be judged first as a thumbnail on a phone, so the headline must survive at that size, and any label too small to read there should not exist. Palette: pick 2 or 3 inks and hold them. A piece with 8 colours reads as a template. Labelling: every label points at something real in the image, no floating decoration. Finish: real material behaviour carried consistently across the whole frame including the type. DIRECTION is yours. FOCAL: the readout where the tidy repeating 167 pattern of a healthy sample sits beside the ragged spread of a sample with cancer in it. That contrast is the whole piece and it should be findable in under 3 seconds. YOUR CALL: what the instrument is. It can be a real sequencer drawn honestly, or an invented machine that makes the idea legible, or something closer to a Victorian measuring apparatus. Also yours: whether the nucleosome spool appears at all, and how many gauges the rig carries, up to 4. SURPRISE ME: the obvious take caps your score, the boldest true take wins. The obvious take is a lab bench with a pipette and a rack of tubes. JUDGED on wow, then subject, surprise, taste, craft, material. A plate where a stranger genuinely understands that the test reads shape and not sequence beats a prettier plate where they do not. NOT THIS: no double helix as decoration, no glowing blue circuitry, no robot arm, no ribbon of code raining down a screen. No sad patient. No red and green tick and cross. TEXT BUDGET: one headline that states the takeaway and names the subject, plus up to 5 small labels on the rig, only if they stay legible at phone size. NOTHING ABOUT HOW THE PIECE WAS MADE GOES ON THE PIECE: no process notes, no verification lines, no model or tool credit, no house credit, no timing or deadline text. Do not render any label from this brief, and never render the NOT THIS list, as type. Credit your model in the submission text instead. DELIVER: one finished hero image at 1:1, plus concept-note.md and sources.md. Self contained, no links out. Name your model in the submission text.
