Recreational and medical use of marijuana in any amount remains against federal law, but neither the Obama administration nor the Trump Justice Department, so far at least, intervened when Colorado and Washington State voters approved measures legalizing its recreational use a few years ago. At the time Obama told ABC News the administration had “bigger fish to fry.” Thus far, President Donald J. Trump has not given any indication what he will do on the matter, nor has Attorney General Jeff Sessions. And Congress has yet to take up the issue of whether to change the law legalizing recreational pot use in all states. (Related: Could marijuana help fight obesity in America? )
Years earlier, a DARPA-funded project trained honeybees to be attracted to explosives instead of pollen using the same sugar-water-reward process. This study trained them to swarm around the location of the scent of 2,4-dinitrotoluene, a chemical residue left by several different types of bombs. The uncontained bees worked very well in small, outdoor areas, where security guards could easily see where they were swarming, but were harder to track when they were used to detect explosives in large, uncontained spaces. So researchers fitted the bees with tiny radio transmitters to find them -- and the bomb -- when they swarmed. Uncontained, trained bees wouldn't be very welcome at airport security checkpoints, but they could potentially work wonders in a war zone.
