Another study published on the same day finds that humanly traversable wormholes may be possible if reality can broadly be described by the Randall–Sundrum model 2, which is a brane-based theory consistent with string theory.
A new global food emissions database indicates that food systems are responsible for one third of the global anthropogenic GHG emissions.Study results indicate that limiting global warming to 1.5 ☌ would prevent most of the tropics from reaching the wet-bulb temperature of the human physiological limit.Scientists propose storing DNA and other biological reproductive structures in a "lunar ark" on the Moon of all 6.7 million species of plants, animals and fungi known on Earth – to help assure their survivability over the years.Astronomers report the discovery of a quasar known as P172+18, the most distant source of radio emissions known to date, some 13 billion light years away.5 March – NASA names the landing site of the Perseverance rover in Jezero crater as " Octavia E.4 March – COVID-19 pandemic: Scientists report a problematic COVID-19 variant, less susceptible to vaccines, a combination of British B.1.1.7 and South African E484K (Eeek) mutations, in the state of Oregon.Unlike mitochondria, which play the same role in eukaryotes, it enables its host to breathe nitrate instead of oxygen. Scientists report the discovery of an endosymbiont, bacteria Azoamicus ciliaticola, of an anaerobic ciliate to which it provides energy in the stored form of ATP.The robot features artificial muscles and wings out of pliable materials and electronics distributed within its silicone body and could be used for exploration and environmental monitoring.
Scientists demonstrate a bioinspired self-powered soft robot for deep-sea operation at the deepest part of the ocean at the Mariana Trench.COVID-19 pandemic: Scientists report that a much more contagious SARS-CoV-2 variant, Lineage P.1, first detected in Japan, and more recently found in Brazil, as well as in several places in the United States, may be associated with COVID-19 disease reinfection after recovery from an earlier COVID-19 infection.A study published on 31 March finds higher intake of processed meat was associated with "a higher risk of mortality and major CVD". citizens shows associations between meat intake with risks of some of 25 common conditions, including ischaemic heart disease and diabetes, as well as a lower risk of iron deficiency anaemia. A study of data on half a million U.K.Scientists report substantially more precise and regionally subdivided end times of the Acheulean, finding that it persisted long after the diffusion of Middle Palaeolithic technologies in multiple continental regions and ended over 100,000 years apart.The study's conclusions include robust rationales for searching artifacts within the Solar system. They classify signatures based on a metric about the distance of humanity to the capacity of developing the signature's required technology, associated methods of detection and ancillary benefits of their search. NASA-sponsored online workshop TechnoClimes 2020 about mission concepts for the search of technosignatures is published. A scientific review produced by the i.a.1 March: A review classifies SETI technosignatures.
