Sponsored by the local mosquito control board and U.K.-based biotech firm Oxitec, the ad promotes a contentious plan to release millions of genetically modified Aedes aegypti mosquitoes here to test a new method of bioengineered pest control. It’s the first-ever such experiment in the United States, and one that has turned this chain of sun-soaked island communities into a battleground over scientific truth, government authority, and humanity’s right to modify nature.

This study aimed to understand the extent to which cannabis-related risk perception and COVID-19-related health worries were associated with the reported reduction in sharing cannabis smoking products to mitigate the risk of the coronavirus transmission or infection. This association was tested in two different periods in terms of toughness of national lockdown policy imposed in the first months of the pandemic in Israel. The study population included adult recreational cannabis users who completed one of the two online cross-sectional surveys dedicated to COVID-19 and the cannabis use situation in Israel in the first h...

The decision comes a few days…
