Summary
In science news around the world, the U.S. Food and Drug Administration (FDA) cracks down on stem cell labs, Brazil opens one of its largest national reserves to gold and iron mining, and the International Atomic Energy Agency launches a global bank for low-enriched uranium. Also, FDA clears the party drug ecstasy for post-traumatic stress disorder clinical trials, and U.S. courts rule that the federal government must consider the impacts of major energy projects on climate change. Plus, rumors abound over a new gravitational wave signal, zebrafish can be trained to crave—and self-administer—opioids, astronomers discover the source of a nova witnessed in the 15th century, and burying beetles concoct a "cocktail" of microbe-laced slime to keep their larvae healthy.
