2019–2020 Vaping Lung Illness Outbreak
Template:Infobox outbreak An outbreak of severe vaping-associated lung illness starting in 2019 is ongoing among users of cannabis vaping products, almost exclusively in the United States. The first cases were identified in Illinois and Wisconsin in April 2019; as of January 21, 2020, a total of 2,711 hospitalized cases, including 60 deaths have been confirmed by the U.S. Centers for Disease Control. Cases peaked in September 2019, and have been slowly declining since. CDC investigators identified direct exposure to chemicals present in vaping products as responsible for the outbreak. Vitamin E acetate is a very strong culprit of concern in the lung illnesses related to THC-based vaping products, but the CDC did not rule out other chemicals as possible causes. Though patients have reported using vaping products containing THC, nicotine, or both types, about 86% of patients studied by the CDC admitted THC use. The majority of those affected were young adults 18-34, which is the group with the greatest prevalence of cannabis use in the US. Nicotine-containing products are regulated in the U.S. by the Food and Drug Administration; THC products are illegal under federal law, but allowed and regulated by some states. Prior to the outbreak, vitamin E acetate was used in low concentrations, or lower than 20% of the formula in vape cartridges, as a thickening agent. As a result of a limited availability of cannabis in California as well as high demand, illicit sellers had used about 50% or higher of diluent thickeners in their formulas to bulk up tiny potency vape cartridges, and vitamin E acetate is a common choice because it resembles THC oil. Some jurisdictions took action to restrict the sale of products containing vitamin E acetate and other chemicals in response to the outbreak, but THC products in states where it is illegal and some nictotine-containing products are produced illegally (and sometimes obtained illegally in jurisdictions where legal, by underage consumers).

2020 AV2
2020 AV2 is a near-Earth asteroid discovered by the Zwicky Transient Facility on 4 January 2020. It is the first asteroid discovered to have an orbit completely within Venus's orbit, and is thus the first and only known member of the inner-Venusian Vatira population of Atira-class asteroids. 2020 AV2 has the smallest known aphelion and third-smallest known semi-major axis among all asteroids. With an absolute magnitude around 16.4, the asteroid is expected to be larger than 1 km in diameter.

2020 Nintendo Data Leak
The 2020 Nintendo data leak, more commonly referred to as the Nintendo Gigaleak is a series of leaks of data from Japanese video game company Nintendo on the anonymous imageboard website 4chan. The releasing of data started in March 2018, but became most prominent in 2020. Nine main sets of data leaked on 4chan, ranging from game and console source code to internal documentation and development tools. The name "Gigaleak" mainly refers to the second leak on July 24, 2020, which was 3 gigabytes in size. The leaks are believed to have come either from companies contracted by Nintendo in the design of these consoles, or from individuals previously convicted of intrusion into Nintendo systems. An earlier, much smaller leak had also occurred in 2018 which had the Nintendo Space World 1997 demos for Pokémon Gold and Silver leaked. The leaks are infamous for the sheer size and the amount of internal material leaked; video game journalists have described the magnitude of the leaks as unprecedented, and suggested that they might have significant effects for emulation and to preservationists, in addition to the legal questions posed by the leak. As of May 2021, Nintendo has not made any official response.

2020 Twitter Bitcoin Scam
User:RMCD bot/subject notice On July 15, 2020, between 20:00 and 22:00 UTC, around 130 high-profile Twitter accounts were compromised by outside parties to promote a bitcoin scam. Twitter and other media sources confirmed that the perpetrators had gained access to Twitter's administrative tools so that they could alter the accounts themselves and post the tweets directly. They appeared to have used social engineering to gain access to the tools via Twitter employees. The scam tweets asked individuals to send bitcoin currency to a specific cryptocurrency wallet, with the promise of the Twitter user that money sent would be doubled and returned as a charitable gesture. Within minutes from the initial tweets, more than 320 transactions had already taken place on one of the wallet addresses, and more than US$110,000 of equivalent bitcoin had been deposited in one account before the scam messages were removed by Twitter. In addition, full message history data from eight non-verified accounts was also acquired. Dmitri Alperovitch, the co-founder of cybersecurity company CrowdStrike, described the incident as "the worst hack of a major social media platform yet." The FBI and other law enforcement agencies are investigating the scam and the security used by Twitter. Security researchers expressed concerns that the social engineering used to execute the hack can affect the use of social media in important online discussions, including the lead-up into the 2020 United States presidential election.

2020 XL5
2020 XL5 is a near-Earth asteroid and Earth trojan discovered by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii on 12 December 2020. It oscillates around the Sun–Earth L4 Lagrangian point (leading 60°), one of the dynamically stable locations where the combined gravitational force acts through the Sun's and Earth's barycenter. Analysis of 2020 XL5's trojan orbit stability suggests it will remain around Earth's L4 point for at least four thousand years until gravitational perturbations from repeated close encounters with Venus destabilize its trojan configuration. With a diameter about 1.2 km (0.75 mi), 2020 XL5 is the second Earth trojan discovered and is the largest of its kind known, after 2010 TK7.
