Electric charge may have been key ingredient in planet formation, experiment finds
Researchers have struggled to explain the mechanisms of planet formation from protoplanetary dust particles, due to the "bouncing barrier", which prevents particles from forming a planet under the force of gravity. A new experiment used tiny glass beads as a replacement for dust particles, and found that in a weightless environment, the particles came together due to differences in electric charge, sometimes in clumps of thousands.

Malaria medication could be a cure for coronavirus, research finds
Researchers led by infectious disease expert Didier Raoult have found that the drug hydroxychloroquine, used in the treatment of malaria, could potentially be a cure for the novel coronavirus, with a lab experiment involving 26 patients revealing more than 50 percent of coronavirus-positive patients tested negative for COVID-19 after a week of treatment with hydroxychloroquine.

Groundbreaking experiment cools particle to the quantum limit
An experiment designed by Markus Aspelmeyer and his team of researchers at the University of Vienna has successfully cooled a nanoparticle to the quantum cooling limit, reaching the particle's ground state at a minimum temperature of twelve millionths of a Kelvin, through the precise use of an array of lasers to levitate the particle in a specially constructed cavity.

NASA's suitcase-sized exoplanet hunter Asteria may be lost
NASA deployed the Asteria spacecraft, a suitcase-sized satellite termed a CubeSat, from the International Space Station in 2017 with the mission to observe dimming in stars' brightness as evidence of orbiting planets. Asteria successfully finished three missions before losing contact on December 5, 2019, and is thought to be lost.

Fox domestication study reveals surprising discoveries for scientists
Researchers concluded a 60-year experiment that studied the gradual domestication of silver foxes in Siberia. The study surprisingly found that domestication syndrome, a widely held theory which states that certain animals are genetically pre-disposed to domestication, may not necessarily hold true, and animals may have chosen to self-domesticate themselves instead by adapting to the human world.
