Contaminated sample

Here are a few expert discussions on the topic of contaminated samples:

1. Peter Attia and Brian Deer explained the contamination in research involving formalin and nitrogen preservation methods. Formalin can degrade nucleic acids, requiring more PCR cycles to detect genetic material compared to nitrogen-preserved samples 1.

2. Professor Paul Steinhardt discussed the improbability that a rare structure found in a contaminated sample was produced by humans, highlighting the intriguing nature of the contamination 2.

3. Josh Barnett and Joe Rogan talked about contamination in supplements, focusing on trace amounts of substances found due to improper cleaning of mixing vats. They emphasized the importance of third-party testing to ensure supplement purity 3.
