Description

Eun Hye Lee and co-authors build a glowing probe that estimates time since death from a tiny RNA in muscle, in this 2024 paper. Forensic teams need the postmortem interval early in an investigation. Small RNAs survive well after death, making them candidate clocks. The team designed a hairpin probe that lights up when it meets one muscle microRNA, miR-133a-5p, and tested it in mouse tissue kept cold or at room temperature.

The probe's glow rose in lockstep with the target's amount, down to a low detection floor. In the mouse muscle, the RNA's level stayed steady across ten days at both temperatures. That flat line, the authors note, suits it as a reference marker. The test finishes in thirty minutes after RNA extraction, suiting field use.
