In science news around the world, the United States' Advanced Research Projects Agency-Energy, part of the Department of Energy, announces a slew of projects that it hopes will break the logjam in fusion research, the National Academies launches an initiative to discuss the ethically fraught topic of human embryo gene editing, and German scientists join other genetically modified (GM) foods proponents in an unusual gamble: urging the country's government to label all GM products to convince people there's nothing to be afraid of. Also, agriculturalist Cary Fowler discusses his work to protect the genetic diversity of the world's crops, featured in the upcoming documentary Seeds of Time. And researchers are closing in on a long-standing goal of engineering genes into yeast that will enable the microbes to make opiates—which, policy experts worry, could make it too easy for narcotics dealers to manufacture the drugs as well.
