Antimicrobial resistance (AMR) in waterways presents a critical threat. If commonly used antibiotics are deemed useless, decades of progress in human medicine and agriculture could be undermined.

Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability helps ...

Paxlovid may offer marginal benefits for low-risk children with COVID-19; however, among high-risk children with COVID-19, Paxlovid is a safe oral option.
