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 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 CO 2 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 (10 15 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-CO 2 -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.

  • 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.

  • 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).

• 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 (H ) 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 .
