March 2022 in science

1 March Researchers report the development of a solar panel integrated system that, using a hydrogel, cools the panel or produces fresh water to irrigate enclosed crops beneath. Atmospheric scientists report that the 2022 volcano eruption in Tonga, Pacific Ocean – the largest recorded volcanic eruption since 1991 which eruption reportedly cooled global climate by ~0.6°C during 15 months – did not have a cooling effect (volcanic winter) of significance to global climate change (i.e. a cooling of ~0.004°C during the first year). 2 March – Researchers report the development of a system that combines the MOST solar thermal energy storage system with a chip-sized thermoelectric generator to generate electricity from it. 4 March – A study using brain-scans of 36,678 UK Biobank participants shows that negative associations between alcohol intake and brain macrostructure and microstructure are apparent in individuals consuming an average of "one to two daily alcohol units" that some may consider light or moderate consumption. A study of 371,463 UK Biobank participants' cardiovascular health published on 25 March shows that while "light to moderate alcohol consumption was associated with healthier lifestyle factors" than in alcohol-abstainers, adjustment for such factors suggests that in principle minimizing alcohol intake could lower risks for (or negative effects towards) hypertension and coronary artery disease for everybody. 7 March Pig calls are decoded into positive or negative emotions, using an algorithm based on ~7,000 audio recordings classified by an artificial neural network for potential use in farms. A new cellular rejuvenation therapy of bursts of iPSC reprogramming is reported, which can reverse aspects of aging in mice, without causing cancer or other health problems. Researchers report that more than three-quarters of the Amazon rainforest has been losing resilience due to deforestation and climate change since the early 2000s as measured by recovery-time from short-term perturbations ("critical slowing down" (CSD)), reinforcing the theory that it is approaching a critical transition. On March 11, INPE reports satellite data that show record-high levels of Amazon deforestation in Brazil for a February (199 km²). Scientists report how COVID-19 impacts the brain at least temporarily based on brain-scans and cognitive tests of 785 UK Biobank participants (401 positive cases), including grey matter thickness- and brain size-reductions. Researchers report the first artificial parthenogenesis in mammals (viable mice offspring born from unfertilized eggs). A study suggests that half of the US population has been exposed to substantially detrimental lead levels in early childhood – mainly from car exhaust whose lead pollution peaked in the 1970s. Researchers report the development of 3D-printed nano-"skyscraper" electrodes that house cyanobacteria for extracting substantially more sustainable bioenergy from their photosynthesis than before. Researchers report that the widely used supplements glycine and NAC when combined as "GlyNAC", which previously showed various beneficial effects in humans i.a. in a small trial by the authors, can extend lifespan by 24% in mice when taken at old age. Progress in biomarkers-based cancer screening is reported: researchers estimate risks for prostate cancer based on age, PSA and hK2 (7 Mar). Researchers achieve high prediction accuracy for pancreatic cancer using faecal microbiota biomarkers (8 Mar). A cancer test that checks for more mutations than ever before in one tissue sample is launched by a biotech-company (15 Mar). The first clinical test of a technology to detect early-stage cancer via novel biomarkers of extracellular vesicles concludes with promising results, possibly reaching screening-relevant sensitivities at high specificity at least for pancreatic cancer (17 Mar). Using drug discovery artificial intelligence algorithms, researchers generate 40,000 potential chemical weapon candidates, which may be relevant to timely regulation of chemicals and related products that can be used to manufacture the fraction of viable candidates and either illustrates or proves that such software is dual-use technology. 8 March – Researchers report SARS-CoV-2 variant recombinant viruses that contain elements of Delta and Omicron – Deltacron (also called "Deltamicron"). Recombination occurs when a virus combines parts from a related virus with its genetic sequence as it assembles copies of itself. It is unclear whether Deltacron – which is not to be confused with "Deltacron" reported in January – will be able to compete with Omicron and whether that would be detrimental to health. 9 March Researchers in the Antarctic announce they have found Endurance, one of the greatest ever undiscovered shipwrecks, which sank in 1915 during Ernest Shackleton's exploration. Doctors report that an antiseptic drug reduced recurring urinary tract infections in a trial as effectively as antibiotics whose prevalent use is implicated in antimicrobial resistance. Researchers report that, on average, the elderly played "a leading role in driving up GHG emissions in the past decade and are on the way to becoming the largest contributor" due to factors such as demographic transition, low informed concern about climate change and high expenditures on carbon-intensive products like energy which is used i.a. for heating rooms and private transport. Results from a study imply "that all living cells probably possess a common mechanism of [methane] formation". This universal mechanism is based on interactions among ROS, iron and methyl donors. Scientists demonstrate limits and the scale of challenge of genetic-editing-based de-extinction, suggesting resources spent on more comprehensive de-extinction such as of the woolly mammoth may currently not be well allocated and substantially limited. Using graphene and molybdenum disulfide, Chinese scientists create a transistor gate with a length of 0.34 nm, equivalent to just one carbon atom, by exploiting the vertical aspect of the device. 10 March A study estimates that "relocating current croplands to [environmentally] optimal locations, whilst allowing ecosystems in then-abandoned areas to regenerate, could simultaneously decrease the current carbon, biodiversity, and irrigation water footprint of global crop production by 71%, 87%, and 100%", with relocation only within national borders also having substantial potential. A study reports that excess mortality data suggests that between Jan 1, 2020, and Dec 31, 2021, ~18.2 million people died worldwide because of the COVID-19 pandemic (compared to 5.94 million reported deaths). It notes that further research could help distinguish the proportions directly caused by COVID-19 from those caused by indirect consequences of the pandemic. 11 March – Researchers demonstrate electrostatic dust removal from solar panels. 12 March – Biomedical gerontologists demonstrate a mechanism of anti-aging senolytics, in particular of Dasatinib plus Quercetin (D+Q) – an increase of α-Klotho as shown in mice, human cells and in a human trial. 14 March – Impact and reactions to the 2022 Russian invasion of Ukraine in science: at least one journal enacts a immediate publishing boycotts against Russia-located researchers or institutions (before 14 Mar). Researchers caution that a surge of various diseases is to be expected due to the war (15 Mar). Scientists warn that policy-makers should not abandon sustainable farming practices to increase grain production in response to resulting food insecurity, but change "the demand side which can lead to both a more resilient and more sustainable global food system" (18 Mar) – such as limiting the import of animal feed (10 Mar) – and e.g. expanding wheat production in high-productivity areas (22 Mar). Scientists explain why the Ukraine biolabs conspiracy theory is disinformation (11 Mar). Scientists describe dangers of nuclear energy facilities within war-zones and bombing/shelling of or near them – as well as of waste-sites – by Russia. 15 March – Neuroscientists report that mutations that enable people to naturally sleep as short as five hours reduce Alzheimer's pathology in mice. On 17 March, a study reports that longer and more frequent daytime naps appears to be associated with higher risk of Alzheimer's dementia. 16 March Researchers report that over 80% of the growth of methane emissions during 2010–2019 was caused by tropical terrestrial emissions. Results of a study suggest that many earlier brain–phenotype studies ("BWAS") produced invalid conclusions as reproducibility of such studies requires samples from thousands of individuals due to small effect sizes. 18 March Neuroscientists report that in mice suppression of claustrum appears to attenuate anxiety/stress and increase chronic stress-resistance. Scientists report evolution experiments of self-replicating RNA showing a segment of how life may have emerged on Earth (abiogenesis) e.g. from RNA world conditions – from the long self-replicating RNA chemicals to diverse complex molecules. 21 March The number of confirmed exoplanets exceeds 5,000. Before formal publication of the 'Global Carbon Budget 2021' preprint, scientists report, based on Carbon Monitor data, that after COVID-19-pandemic-caused record-level declines in 2020, global CO2 emissions rebounded sharply by 4.8% in 2021, indicating that at the current trajectory, the 1.5 °C carbon budget would be used up within 9.5 years with a ⅔ likelihood. 24 March: Scientists describe and quantify the biophysical mechanisms by which forests influence climate. 23 March – A far-UVC (ultraviolet light) air purification system is demonstrated by scientists, which can reduce levels of an airborne pathogen by 98% within minutes. This is equivalent to 184 air changes per hour – better than HEPA air cleaners – and is proposed as a solution for COVID-19 and other future pandemics. On 9 March, a study reports promising results of tests of durably biocide treated air filters for preventing the spread of airborne pathogens like SARS-CoV-2, including of field trials onboard public rail transport. 24 March A physical speed limit for electronic computers, optoelectronics, of approximately one petahertz (1015 Hz) is reported. This theoretical maximum is about 100,000 times faster than modern transistors. Scientists review the biophysical mechanisms by which forests influence climate, showing that beyond 50°N large scale deforestation leads to a net global cooling, that tropical deforestation leads to substantial warming from non-CO2-impacts, and that as well as how standing tropical forests help cool the average global temperature by more than 1 °C. Researchers report the development of the first prototype, photonic, quantum memristive device for neuromorphic (quantum-)computers/artificial neural networks. 25 March – Genetic engineers report field test results that show CRISPR-based gene knockout of KRN2 in maize and OsKRN2 in rice increased grain yields by ~10% and ~8% and did not find any negative effects. 30 March – WHL0137-LS, also known as Earendel, is reported as the farthest individual star ever discovered, its light having taken 12.9 billion years to reach Earth. 31 March Astronomers report the discovery of K2-2016-BLG-0005Lb as the most distant exoplanet found by Kepler to date, at 17,000 light years. Depletion of ozone in the stratosphere and, more importantly (60%), ozone increase in the troposphere is shown to be responsible for ~30% of upper Southern Ocean interior warming between 1955 and 2000.

April

• 1 April
  • Biochemists report finishing the complete sequence of the human genome.
  • A study shows that, contrary to widespread belief, body sizes of mammal extinction survivors of the dinosaur-times extinction event were the first to evolutionarily increase, with brain sizes increasing later in the Eocene.
• 4 April
  • The Intergovernmental Panel on Climate Change (IPCC) releases the third and final part of its Sixth Assessment Report on climate change, warning that greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030, in order to likely limit global warming to 1.5 °C (2.7 °F).
  • Researchers announce a new technique for accelerating the development of vaccines and other pharmaceutical products by up to a million times, using much smaller quantities based on DNA nanotechnology.
  • Alzheimer's disease (AD) research progress:
    A study reports 42 new genes linked to an increased risk of AD. Researchers report a potential primary mechanism of sleep disturbance as an early-stage effect of neurodegenerative diseases. Researchers identify several genes associated with changes in brain structure over lifetime and potential AD therapy-targets (5 Apr).

5 April: A study suggests that if "quintessence" is an explanation for dark-energy and current data is true as well, the world may start to end within the next 100 My, during which accelerating expansion of the Universe would inverse to contraction (a cyclic model).

• 5 April
  • COVID-19 pandemic: Preclinical data for a new vaccine developed at the Medical University of Vienna indicates it is effective against all SARS-CoV-2 variants known to date, including Omicron.
  • A study presents a mechanism by which the hypothesized potential dark-energy-explaining quintessence, if true, would smoothly cause the accelerating expansion of the Universe to inverse to contraction, possibly within the cosmic near-future (100 My) given current data. It concludes that its end-time scenario theory fits "naturally with cyclic cosmologies [(each a theory of cycles of universe originations and ends, rather than the theories of one Big Bang beginning of the Universe/multiverse, to which authors were major contributors)] and recent conjectures about quantum gravity".

6 April: The first known dinosaur fossil linked to the actual day of the Chicxulub impact is reported.

• 6 April
  • U.S. Space Command, based on information collected from its planetary defense sensors, confirms the detection of the first known interstellar object. The purported interstellar meteorite, technically known as CNEOS 2014-01-08, impacted Earth in 2014, and was determined, based on its hyperbolic trajectory and estimated initial high velocity, to be from beyond the Solar System. The 2014 meteorite was detected three years earlier than the more recent and widely known interstellar objects, 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019.
  • The first known dinosaur fossil linked to the very day of the Chicxulub impact is reported by paleontologists at the Tanis site in North Dakota.
  • One science journalist reflects on the global management of the COVID-19 pandemic in relation to science, investigating the question "Why the WHO took two years to say COVID is airborne" – a finding hundreds of scientists reaffirmed in an open letter in July 2020 – with one indication that this may be one valid major concern to many expert scientists being several writings published by news outlets.
  • A study decodes electrical communication between fungi into word-like components via spiking characteristics.
  • Researchers demonstrate semi-automated testing for reproducibility (which is lacking especially in cancer research) via extraction of statements about experimental results in, as of 2022 non-semantic, gene expression cancer research papers and subsequent testing with breast cancer cell lines via robot scientist "Eve".

6 April: A study decodes electrical communication between fungi into word-like components.

• 7 April
  • Astronomers report the discovery of HD1, considered to be the earliest and most distant known galaxy yet identified in the observable universe, located only about 330 million years after the Big Bang 13.8 billion years ago, a light-travel distance of 13.5 billion light-years from Earth, and, due to the expansion of the universe, a present proper distance of 33.4 billion light-years.
  • Physicists from the Collider Detector at Fermilab determine the mass of the W boson with a precision of 0.01%. The result hints at a flaw in the Standard Model.
  • A trial of estimated financial energy cost of refrigerators alongside EU energy-efficiency class (EEEC) labels online finds that the approach of labels involves a trade-off between financial considerations and higher cost requirements in effort or time for the product-selection from the many available options which are often unlabelled and don't have any EEEC-requirement for being bought, used or sold within the EU.
• 8 April
  • Bioresearchers demonstrate an in vitro method (MPTR) for rejuvenation (including the transcriptome and epigenome) reprogramming in which fibroblast skin cells temporarily lose their cell identity.
  • Researchers show air pollution in fast-growing tropical cities caused ~0.5 million earlier deaths in 2018 with a substantial recent and projected rise, proposing "regulatory action targeting emerging anthropogenic sources".
• 11 April – A study confirms antidepressant potential of psilocybin therapy protocols (which use the active ingredient in psilocybin mushrooms), providing fMRI data about a correlated likely major effect mechanism – global increases in brain network integration.
• 12 April – Science and the 2022 Russian invasion of Ukraine:
  An editorial in a scientific journal reports that relevant areas of food system research are patchy and lack independent assessments. An editorial projects significant gender and age imbalance in the population in Ukraine as a substantial problem if most refugees, as in other cases, do not return over time (4 Apr). A preprint reports impacts of the Ukrainian power grid synchronization with Continental Europe (15 Apr).

22 April: A study outlines rationale for space governance of satellites/space debris similar to terrestrial environmental regulations.

• 14 April
  • GNz7q, a distant starburst galaxy, is reported as being a "missing link" between supermassive black holes and the evolution of quasars.
  • A study describes the impact of climate change on the survival of cacti. It finds that 60% of species will experience a reduction in favourable climate by 2050–2070, with epiphytes having the greatest exposure to increased warming.
  • A preprint demonstrates how backdoors can be placed undetectably into classifying (e.g. posts as "spam" or well-visible "not spam") machine learning models which are often developed and/or trained by third parties. Parties can change the classification of any input, including in cases with types of data/software transparency, possibly including white-box access.

26 April: Results of the 'Global Carbon Budget 2021' pass peer-review, showing problematic continuation of GHG emissions trends.

• 16 April – A review suggests that global prevalence of long COVID conditions after infection could be as high as 43%, with the most common symptoms being fatigue and memory problems.
• 19 April – NASA publishes its Planetary Science Decadal Survey for 2023-2032. The future mission recommendations include a Uranus orbiter (the first visit to the planet since 1986) and the Enceladus Orbilander (landing in the early 2050s).
• 20 April
  • Micronovae, a previously unknown class of thermonuclear explosions on the surface of white dwarfs, are described for the first time.
  • A study shows that common single-use plastic products – such as paper coffee cups that are lined with a thin plastic film inside – release trillions of microplastics-nanoparticles per liter into water during normal use.
• 21 April – Researchers discover that humans are interrupting a 66-million-year-old feature of ecosystems, the relationship between diet and body mass, by driving the largest vertebrate animals towards extinction, which they suggest could have unpredictable consequences.
• 22 April
  • The Large Hadron Collider recommences full operations, three years after being shut down for upgrades.
  • Scientists suggest in a study that space governance of satellites/space debris should regulate the current free externalization of true costs and risks, with orbital space around the Earth being an "additional ecosystem" which should be subject to regulations as e.g. oceans on Earth.
  • Cancer research progress:
    The largest study of whole cancer genomes reports 58 new mutational signatures and shows that for each organ "cancers have a limited number of common signatures and a long tail of rare signatures". A study reports presence of certain bacteria in the prostate and urine for aggressive forms of prostate cancer, with biomarker- and therapeutic potentials being unclear (18 Apr).
• 25 April
  • Novel foods such as under-development cultured meat, existing microbial foods and ground-up insects are shown to have the potential to reduce environmental impacts by over 80% in a study.
  • A review about meat and sustainability of food systems, animal welfare, and healthy nutrition concludes that its consumption has to be reduced substantially for sustainable consumption and names broad potential measures such as "restrictions or fiscal mechanisms".
  • A new type of cell death 'erebosis' is reported after copper-dependent cell death was first reported the previous month.
• 26 April
  • Scientists report the detection of purine and pyrimidine nucleobases in several meteorites, including guanine, adenine, cytosine, uracil and thymine, and claim that such meteoritic nucleobases could serve as "building blocks of DNA and RNA on the early Earth".
  • The Global Carbon Budget 2021 concludes that fossil CO₂ emissions rebounded by around +4.8% relative to 2020 emissions – returning to 2019 levels, identifies three major issues for improving reliable accuracy of monitoring, shows that China and India surpassed 2019 levels (by 5.7% and 3.2%) while the EU and the US stayed beneath 2019 levels (by 5.3% and 4.5%), quantifies various changes and trends, for the first time provides models' estimates that are linked to the official country GHG inventories reporting, and shows that the remaining carbon budget at 1. Jan 2022 for a 50% likelihood to limit global warming to 1.5 °C is 120 GtC (420 GtCO₂) – or 11 years of 2021 emissions levels.
  • Scientists propose and preliminarily evaluate a likely transgressed planetary boundary for green water in the water cycle, measured by root-zone soil moisture deviation from Holocene variability. A study published one day earlier integrates "green water" along with "blue water" into an index to measure and project water scarcity in agriculture for climate change scenarios.
• 27 April
  • A lineage of H3N8 bird flu is found to infect humans for the first time, with a case reported in the Henan province of China. Months earlier, H5 strain bird flu viruses (HPAIv) have been detected in Canada and the US.
  • A study extends global assessments of shares of species threatened by extinction with reptiles, which often play functional roles in their respective ecosystems, indicating at least 21% are threatened by extinction. One day later, scientists quantify global and local mass extinction risks of marine life from climate change and conservation potentials.
  • Researchers report routes for recycling 200 industrial waste chemicals into important drugs and agrochemicals using a software for computer-aided chemical synthesis design, helping enable "circular chemistry" as a potential area of a circular economy.
• 28 April
  • A comprehensive review reaffirms likely beneficial health effects with links to health/life extension of cycles of caloric restriction and intermittent fasting as well as reducing meat consumption in humans. It identifies issues with contemporary nutrition research approaches, proposing a multi-pillar approach, and summarizes findings towards constructing – multi-system-considering and at least age-personalized dynamic – refined longevity diets and proposes inclusion of such in standard preventive healthcare.
  • A company reports results of a phase 3 clinical trial, indicating that tirzepatide could be used for substantial weight loss – possibly larger than the, as of 2022 also expensive, semaglutide approved by the FDA in 2021 – in obese people.
  • Researchers publish projections for interspecies viral sharing, that can lead to novel viral spillovers, due to ongoing climate change-caused range-shifts of mammals (mostly bats) for use in efforts of pandemic prevention.

May

12 May: Sagittarius A*, black hole in the center of the Milky Way, revealed by the Event Horizon Telescope team

• 1 May
  • A preprint indicates Omicron subvariants BA.4 and BA.5 can cause a large share of reinfections, beyond the increase of reinfections caused by the Omicron lineage, even for people who were infected by Omicron BA.1 due to increases in immune evasion, especially for the unvaccinated. On 18 May, a study shows that immunity from an Omicron infection for unvaccinated and previously uninfected is weak "against non-Omicron variants".
  • A preprint suggests that SARS-CoV-2 antibodies in or transmitted through the air are an unrecognized mechanism by which, transferred, passive immune protection occurs. However, if not sustained, protection from passive herd immunity is thought to wane over the course of weeks to months.
• 4 May
  • NASA reports the sonification (converting astronomical data associated with pressure waves into sound) of the black hole at the center of the Perseus galaxy cluster.
  • A single master gene that programs ear hair cells into either outer or inner ones is discovered, overcoming a major hurdle that had prevented the development of these cells to reverse hearing loss.
  • A study complements life-cycle assessment studies, showing substantial deforestation reduction (56%) and climate change mitigation if only 20% of per-capita beef was replaced by microbial protein by 2050.
  • A study suggests, using an epidemiological model, that by reducing the transferred viral load, face masks against COVID19 may be beneficial for variolation whereby "smaller infectious doses tend to yield milder infections, yet ultimately induce similar levels of immunity".
• 5 May
  • The monthly average carbon dioxide (CO₂) level in Earth's atmosphere exceeds 420 parts per million (ppm) for the first time in recorded history.
  • A new approach to reverse of neuropathic pain is demonstrated in animals – a gene therapy for local transgenes encoding for (releasing) GABA which is effective for months at a time.

• 6 May
  • Scientists report the discovery of 830 million year old microorganisms in fluid inclusions within halite that may, potentially, still be alive. According to the researchers, "This study has implications for the search for life in both terrestrial and extraterrestrial chemical sedimentary rocks."
  • Low butyrylcholinesterase specific activity is identified as a potential biomarker for infants at risk for sudden infant death syndrome in a small crowd-funded study.
• 8 May – The UK's Met Office warns, with WMO affirmation, that the probability of global average temperatures reaching 1.5°C above pre-industrial levels over the next five years is now almost 50:50 (48%). It also predicts a more than 90% chance that a new record high will occur in at least one year from 2022-2026.
• 9 May
  • A study reports that declining numbers of the largest fish on Earth, the endangered whale shark, may be linked to collisions with large vessels in the global transport fleet.
  • News outlets report about the first global, interactive AI- and satellite monitoring-based, map and analysis of plastic waste sites to help prevention of plastic pollution, especially ocean pollution.
• 10 May – A sixth mass bleaching event is recorded at the Great Barrier Reef, with 91% of corals affected.

18 May and 2 May: Two separate studies show how two twin-universe cosmological models could each explain specific open problems of physics or cosmology.

• 11 May
  • A logic gate for computation at femtosecond timescales is demonstrated.
  • A study shows that infusing the nourishing cerebrospinal fluid from around brain cells of young mice into aged brains rejuvenates aspects of the brain, identifying FGF17 as a key target for potential therapeutics such as of anti-aging.
  • Scientists close a missing link in the potential origin of life from a RNA world – synergistic formation of peptides and ever-longer RNAs or peptide-decorated RNA, leading to a protein world.
  • A study suggests that in children at age 8–12 during two years, time gaming or watching digital videos can be positively correlated with measures intelligence, albeit correlations with overall screen time (including social media, socializing and TV) were not investigated and 'time gaming' did not differentiate between categories of video games (e.g. shares of games' platform and genre).
• 12 May
  • Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, is imaged for the first time by the Event Horizon Telescope team.
  • Researchers report that lunar soil has been used to grow plants for the first time.
  • Researchers identify the 425 biggest fossil fuel extraction projects globally, of which 40% as of 2020 are new projects that haven't yet started extraction. They conclude that "defusing" these "carbon bombs" – worked on by only "few actors" to date – would be necessary for climate change mitigation of global climate goals. On 17 May, a separate study finds that "staying within a 1.5 °C carbon budget (50% probability) implies leaving almost 40% of 'developed reserves' of fossil fuels unextracted". On 26 May, a study calculates climate policies-induced future lost financial profits from global stranded fossil-fuel assets.
• 17 May
  • Isotopically pure silicon-28 nanowires are shown to conduct heat 150% better than regular silicon, with potential for improved cooling of computer chips.
  • According to reports, the partly-public 2022 United States Congress hearings on UFOs may result in the UAP issue being approached more seriously, such as for a scientific public pursuit for answers and an increased interest from scientists. Known ongoing scientific research is conducted by non-profit groups of researchers that use or develop expensive equipment for new high-quality data rather than analyzing or systematically organizing public data.
  • A review concludes that, like in 2015, pollution (¾ from air pollution) was responsible for 9 million premature deaths in 2019 (one in six deaths). It concludes that little real progress against pollution can be identified and outlines needs for attention and action such as a "formal science–policy interface".
  • A trial shows that Urolithin A can improve muscle strength, exercise performance, and biomarkers of mitochondrial health.
• 18 May
  • NASA reports that the Voyager 1 spacecraft, the farthest human-made object, is sending data that does not reflect what is happening on board with the antenna apparently remaining in its prescribed orientation to Earth. On 17 June, it was reported that NASA is preparing to power down the two Voyager spacecraft in the hope of using the remaining power to extend their operation to about 2030.
  • A study shows how a Twin-world models cosmological model – already extensively studied to find out why gravity appears much weaker than other known forces – could explain the Hubble constant (H₀) tension via interactions between the two worlds. The "mirror world" would contain copies of all existing fundamental particles. On 2 May, another twin/pair-world or "bi-worlds" cosmology is shown to theoretically be able to solve the cosmological constant (Λ) problem, closely related to dark energy: two interacting worlds with a large Λ each resulting in a small shared effective Λ. Previous similar models e.g. attempt to explain the baryon asymmetry – why there was more matter than antimatter at the beginning – with a mirror anti-universe.

• 19 May
  • Scientists report that RNA was found to be formed spontaneously on prebiotic basalt lava glass which is presumed to have been abundantly available on the early Earth.
  • The yellow-billed hornbill of southern Africa, famous for its role in Disney's The Lion King, is reported to be at risk of extinction due to rising temperatures in the region.
  • Boeing starts the one-week second uncrewed test flight of its Starliner space capsule in advance of its first crewed test flight later in 2022.
  • A study estimates losses of 61 metals to help the development of circular economy strategies, showing that usespans of, often scarce, tech-critical metals are short.
• 20 May – Global warming is projected to substantially erode sleep worldwide.

21 May: The World Health Organization confirms a monkeypox outbreak in 12 non-endemic countries.

• 21 May
  • Graphyne is reported to be synthesised for the first time.
  • The WHO informs about the international 2022 monkeypox outbreak in non-endemic countries – an unprecedented number of cases detected outside of Africa after the first of these cases was detected on 6 May. On 24 May, the WHO states that the outbreak can be contained. The main method used for the early containment is 'ring vaccination' – vaccinating close contacts of positive cases via existing vaccines.
• 23 May
  • Researchers report that CRISPR-Cas9 gene editing has been used to boost vitamin D in tomatoes.
  • A study shows why decarbonization must be accompanied by strategies to reduce the levels of short-lived climate pollutants with near-term effects for climate goals.
• 24 May
  • Scientists report the first 3D-printed lab-grown wood. It is unclear if it could ever be used on a commercial scale (e.g. with sufficient production efficiency and quality).
  • A CDC study based on electronic health records shows that "one in five COVID-19 survivors aged 18–64 years and one in four survivors aged ≥65 years experienced at least one incident condition that might be attributable to previous COVID-19" or long COVID. On 18 May, an analysis of private healthcare claims shows that of 78,252 patients diagnosed with 'long COVID', 75.8% had not been hospitalized for COVID-19.
• 25 May – The world's smallest remote-controlled walking robot, measuring just half a millimetre wide, is demonstrated. Potential applications include the clearing of blocked arteries.

30 May: Frontier is confirmed as the world's first exascale supercomputer.

• 27 May
  • A new compact CRISPR gene editing tool better suited for therapeutic (temporary) RNA editing than Cas13 is reported, Cas7-11, – of which an early version was used for in vitro editing in 2021.
  • Science and the 2022 Russian invasion of Ukraine:
    According to a news report academics in Russia are compiling or circulating a list of researchers who have supported Russia's invasion to prevent them from being elected to the Russian Academy of Sciences. An editorial published in a journal notes that remote surgery and types of videoconferencing for sharing expertise (e.g. ad hoc assistance) have been and could be used to support doctors in Ukraine (3 May). A forum contribution analyzes Russian users' reactions to the Bucha massacre on social media – on nationalist Telegram channels (9 May). The FAO estimates that "at least 20 percent of Ukraine's winter crops" "may not be harvested or planted" (13 May). A preprint estimates potential impacts of the EU embargoing fossil fuels from Russia, suggesting implementing such via a partial embargo with tariffs may be beneficial (25 May).

  • Early 2022 monkeypox outbreak research:
    A study reports phylogenomic characterization of the first monkeypox (MP) virus outbreak genome sequences, finding the "presumably slow-evolving" DNA virus has evolved roughly 6–12-fold more mutations than one would expect and 15 SNP mutations since the beginning of the outbreak. The WHO announces that MP is not yet a global public health emergency but a cause for deep concern (25 June). Early overviews and reviews, including about current knowledge about MP prevention and treatment, are published. Scientists are investigating circulating lineages (and potential variants) of the MP virus and compare them to the African endemic lineages. A preprint suggests that cases "where a small fraction of individuals have disproportionately large numbers of partners, can explain the sustained growth of monkeypox cases among the MSM population" (13 June). The MP incubation period is estimated to be 8.5 days on average and up to 21 days (16 June).

• 20 September – Scientists who reported the earliest known interstellar object, CNEOS 2014-01-08, and members of The Galileo Project, report the discovery of an additional candidate interstellar meteor, CNEOS 2017-03-09, in a preprint using the same fireball catalog. They find that the implied material strength of the two objects suggests that interstellar meteors "come from a population with material strength characteristically higher than meteors originating from within the solar system".
• 21 September – Engineers report the development of autonomous 3D-printing drones for construction and repair.
• 22 September
  • Nanoengineers report the development of biocompatible microalgae hybrid microrobots for active drug-delivery in the lungs (22 Sep.) and the gastrointestinal tract (GT) (28 Sep.). The microrobots are related to medical nanobots and proved effective in tests with mice. A separate team reports the development of 'RoboCap', a robotic drug delivery capsule that enhances drug absorption by tunneling through the mucus layer in the GT (28 Sep.).
  • Around September, news outlets report about deployment, research and development of novel military drone technology in the Russo-Ukrainian War in 2022, including demining drones, self-repurposed commercial/hobby drones (including via a hackathon), surveillance microdrones, kamikaze drones, bomb-dropping modified drones, and countermeasures such as electronic ones.
  • Scientists caution about potential spillover of bat sarbecovirus Khosta-2 resistant to COVID-19 vaccines and also using ACE2, suggesting it or something like it could recombine with SARS-CoV-2 as a new threat.
• 26 September
  • Jupiter makes its closest approach to Earth since 1963.
  • NASA's DART crashes into the asteroid Dimorphos in a first test of potential planetary defense.
  • A study invalidates the common argument as is for high medication costs that research and development investments are reflected in and necessitate the treatment costs, finding no correlation for investments in drugs (for cases where transparency was sufficient) and their costs.
• 27 September – A study in the European Journal of Preventive Cardiology finds that drinking two to three cups of ground, instant, or decaffeinated coffee each day is associated with a longer lifespan and lower risk of cardiovascular disease compared with avoiding coffee.
• 28 September
  • A breakthrough in treating Alzheimer's disease is reported by pharmaceutical companies Eisai and Biogen, using a drug called lecanemab, which is designed to remove beta-amyloid proteins from the brain.
  • A study indicates cancer risk from chronic circadian disruption is caused via body-temperature-related heat shock factor 1.
• 29 September
