Summary
In science news around the world, the United States surpasses 500,000 deaths from COVID-19, the world's highest toll. A U.K. ethics board authorizes a research team there to intentionally infect volunteers with the pandemic coronavirus, in a world-first, hotly debated experiment intended to accelerate research on vaccines against the disease. Researchers produce the first clone of an endangered animal native to North America, a black-footed ferret, which could boost the species' genetic diversity and aid restoration efforts. Scientists from poor nations that hold many of the world's tropical coral reefs are often excluded from research teams that "parachute" in for studies, an analysis concludes. The European Space Agency gives preliminary approval to the Harmony mission: two satellites that will monitor glaciers, oceans, and earthquake faults using a technique called interferometric synthetic aperture radar.
