------------------ Not included ------------------

- A brown bear sighting in Spain's Invernadeiro national park is reported for the first time in 150 years

- A maiden flight of China's most powerful rocket to date, the Long March 5B, occurs

- *Proof-of-concept of a quantum radar developed

- *A Seyfert flare 3.5 million years ago with a burst of ionizing radiation from Sagittarius A* created the large X-ray/gamma-ray Fermi Bubbles around the galactic center and reached so far into space that it illuminated the Magellanic Stream – a stream of gas extending from two of the Milky Way's satellite galaxies.

- *Genomic analysis shows that mainland East Asians have a closer genetic relationship to northern Neolithic East Asians instead of southern ones and that migration and gene flow played important roles during the Neolithic Revolution

- *Researchers claim to have developed a low-noise silicon single-photon source compatible with large-scale quantum photonics

- *Researchers project a net increase in the extent and biomass of green snow algae with coastal Antarctica turning more green due to climate change

- *Genome-wide data of 19 Siberians of the Upper Paleolithic to Bronze Age of up to ca. 14,000 years ago show the most deeply divergent connection between Upper Paleolithic Siberians and the indigenous peoples of the Americas and that long-range human mobility across Eurasia during the Early Bronze Age as well as prolonged local admixture that lead to an ancestry that gave rise to all non-Arctic Native Americans.

- One-minute novel coronavirus test with 90% accuracy developed

- *Evidence for the early differentiation of the cline of Italian variation dating back to the Late Glacial and for Neolithic and distinct Bronze Age migrations having further differentiated their gene pools. Ancestors of present-day Italians are believed to have experienced an extraordinary history of migrations and gene flow as main factors underlying their genetic diversity which is one of the highest across Europe

- *Comet ATLAS reaches its nearest point to Earth. The Solar Orbiter spacecraft flies through comet ATLAS' ion tail between May 31 and June 1 as well as its dust tail in the solar wind on June 6.

- Sensor only 11 atoms in size, able to capture spin waves developed

- Chicxulub impactor produced a "worst case" scenario in terms of lethality for the dinosaurs, arriving from the north-east at a 60° angle, which maximised the amount of gases and debris thrown up into Earth's atmosphere

- Novae - likely created in a close binary star system consisting of a white dwarf and either a main sequence, subgiant, or red giant star - are the galactic producers of the element lithium

- *Social networks can function poorly as pathways for inconvenient truths and the interplay between communication and action during disasters may depend on the structure of social networks
