Contaminations contaminate common databases [PDF]
Molecular Ecology Resources, 2020 AbstractThe polymerase chain reaction (PCR) is a very powerful method to detect and identify pathogens. The high sensitivity of the method, however, comes with a cost; any of the millions of artificial DNA copies generated by PCR can serve as a template in a following experiment.

Counterfactual Contamination [PDF]
Australasian Journal of Philosophy, 2021 Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively under-theorized. One structural idea in the literature, the principle of Counterfactual Closure (CC), connects easy possibility with counterfactuals: if it easily could have happened that p, and if p ...

Oxidative damage in metal fragment-embedded Sprague-Dawley rat gastrocnemius muscle
Current Research in Toxicology, 2022 Injuries suffered in armed conflicts often result in wounds with embedded metal fragments. Standard surgical guidance has been to leave fragments in place except under certain circumstances; meaning that individuals may carry these retained fragments for
