- ------------------ Not included ------------------
- - * The Chinese experimental nuclear fusion reactor HL-2M is turned on for the first time, achieving its first plasma discharge.
- - The Washington Post reports a serious warning for people with a "significant" history of allergies and the possibility of "anaphylactoid reactions" regarding the Pfizer COVID-19 vaccine.
- - Scientists report the detection of large-scale X-ray bubbles in the Milky Way halo.
- - * A study finds there to be no direct causal relationship between the proportionally most comparable mass radiations and extinctions, substantially challenging the hypothesis of such creative mass extinctions.
- - * Scientists report that four months old ravens can have physical and social cognitive skills similar to that of adult great apes.
- - Jupiter and Saturn come within a 6' arc (called a great conjunction), giving a rare telescopic view of the two so close together. As the two planets have an apparent size smaller than one arc minute, occultations are extremely rare: this is the closest approach since 1623 and the next occultation will happen in the year 7541.
- - * Publication of research of "counterfactual quantum communication" – whose first achievement was reported in 2017 – by which information can be exchanged without any physical particle traveling between observers and without quantum teleportation. The research suggests that this is based on some form of relation between the properties of modular angular momentum.
- - * Researchers publish projections and models of potential impacts of policy-dependent modulation of how, where, and what food is produced.
- - A new mineral, dark green in colour and named kernowite, is discovered in Cornwall, south-west England.
- - A study finds that face masks reduce the risk of spreading large COVID-19-linked droplets when speaking or coughing by up to 99.9 percent.
- - Scientists determine that desalination membranes are inconsistent in density and mass distribution, and show a way to increase efficiency in the membranes by up to 40 %.
