A recent paper in the journal "Nature" reports that although the 2019–20 Australian brushfires produced 700 million tonnes of carbon dioxide, they also resulted in a massive phytoplankton bloom larger in size than all of Australia that absorbed carbon dioxide as part of the photosynthesis process. The smoke also deposited approximately three times the amount of iron normally found in the ocean.
A study published to the journal "Nature" finds dozens of potential stellar mass black holes in the Galactic Center, suggesting there may be as many as 20,000 orbiting the supermassive black hole Sagittarius A*.
"Nature" publishes research from The Institute of Astrophysics of Andalusia at the Glorieta de la Astronomía of Granada, Spain, describing the discovery that a ring system orbits the trans-Neptunian dwarf planet Haumea.
A research team led by an evolutionary biologist at the University of Arizona publishes a paper in "Nature" on the genetic history of HIV proving that Gaëtan Dugas, the Canadian flight attendant who had been identified for years as "Patient Zero" of the AIDS epidemic in the U.S., did not spread the virus to the country. The study indicates that HIV first spread to the U.S. from the Caribbean around 1970.
Researchers report in the journal Nature the discovery of three potentially habitable, Earth-like exoplanets orbiting TRAPPIST-1, an ultracool dwarf star 40 light-years away in the constellation Aquarius.
"Nature" publishes Penn State University findings of Ancient shells with 430,000-year-old engravings believed to be made by "Homo erectus", changing beliefs on artistic expression and tool use by ancestors of "Homo sapiens". Dutch anthropologist Eugene Dubois found the collection in Java in 1891 and Penn State discovered the markings in a museum in the city of Leiden.
