-90%: Premature births have dropped around the world amid the Covid-19 pandemic, according to the New York Times. Studies found a link between lockdowns and a fall in premature births — one team in Denmark even saw a sharp decline of 90%, though many other reported results were less dramatic. Suggested influencing factors include an increase in rest for some mothers and less exposure to air pollution.

37 volcanoes: Researchers identified 37 recently active volcanoes on Venus, according to a study published in Nature Geoscience. The findings challenge the commonly-held notion among scientists that the planet is effectively geologically dormant.
