A new study finds that prosecutors in North Carolina believe "drug-induced homicide" (DIH) laws are effective at both reducing drug overdoses in a community and curtailing the distribution of illicit drugs. These beliefs are worth noting because there is no evidence to support them, while there is evidence that DIH prosecutions make people in affected communities less likely to call 911—and may actually increase the number of overdoses in a community. https://phys.org/news/2024-03-drug-homicide-prosecutions-north-carolina.html Social Sciences Political science Wed, 06 Mar 2024 14:54:03 EST news628959242 Subaru Telescope discovers the faintest moon around icy giant planets Using some of the largest telescopes in the world, including the Subaru Telescope, a team of astronomers discovered three new natural satellites orbiting the outermost planets in our solar system—one around Uranus and two around Neptune.
