What to know about Microbial clocks can accurately estimate time since death across different climates

The article reports on new research published in Scientific Reports regarding the use of microbial clocks to estimate the postmortem interval (PMI). The study demonstrates that microbial data collected from pig carcasses in the U.K. can be reliably applied to estimate the time since death for human bodies in the U.S. across various climates.

Why it matters

successfully estimated the PMI of human bodies placed in the U.S.

Common ground

For the first time, this showed that microbial data from different species can accurately and reliably estimate time since death in human forensic investigations.

Claim 1: “The research, published in Scientific Reports, assessed bacteria found both inside and outside the noses of pig carcasses as they decomposed outdoors during summer in the U.K.”
SINGLE SOURCE
While the claim is detailed, the provided evidence for this specific claim consists of irrelevant search results (speed tests, political parties). However, the claim is mirrored in the evidence for claim 4. Since no independent authoritative source confirms the 'Scientific Reports' publication specifically in the provided evidence for claim 2, it remains single-source based on the article's internal logic.
