Princeton University researchers find wintertime outbreaks of COVID-19 have been largely driven by whether people adhere to control measures such as mask wearing and social distancing.

Researchers from Princeton University and the University of California-Berkeley found that a one-time legal sale of ivory intended to stifle elephant poaching in Africa actually expanded the black market for ivory and led to the slaughter of more elephants. In general, the work suggests that the partial legalization of some illegal products may in fact encourage black-market activity by attracting new customers and by reducing risk for criminals.
