I feel the microplastics contamination story which turns out to be measuring nitrile gloves used preparing samples is in this space. We can now measure things down to levels that may exceed our ability to exclude them as contaminants, routinely.
- mananaysiempre 4mo agoI’d say that has been true since we started using spectrometers (of all kinds). Those things are preposterously sensitive and pretty damn routine. Nowadays of course there are also other, more narrowly scoped detection methods as well, such as PCR.
- ggm 4mo agoPCR/amplification is black magic. I'm also amazed by "no the DNA will be too old" keeps turning out not to be entirely true: People getting out of jail from re-testing evidence 20+ years later, Hominid DNA statements being made from archaic bones.. Animal population studies used to be (in my understanding) largely observational. Now, people can do scat tests and identify individuals.
