    90 million years ago Antarctica was like Wales

    US, WASHINGTON (ORDO NEWS) — When Roald Amundsen was the first in the history of mankind to reach the South Pole on December 14, 1911, it was unlikely that a brave researcher thought about how this area looked 90 million years ago. But now, scientists have found that in the prehistoric past, Antarctica was a temperate and somewhat swampy rainforest with an average temperature of about 12 ° C. In…

    Incredible: rainforests grew in Antarctica

    US, WASHINGTON (ORDO NEWS) — Even when Antarctica was already at the South Pole, dense rainforests grew on its territory. The incredible find of paleontologists convinces of this. The discovery is described in a scientific article published in the journal Nature. The continents, as you know, do not stand still . But 80-90 million years ago, Antarctica was already in the polar latitudes. However, does this mean that it was…

    Can coronavirus spread to eight meters?

    US, WASHINGTON (ORDO NEWS) — A distance of two meters does not guarantee that a person will not become infected with COVID-19. When a patient coughs and sneezes, viral particles can be transported up to eight meters away. This conclusion is made on a scientific article published Lydia Boriba of MIT in the publication Journal of the American Medical Association. The researcher has been studying the dynamics of strong reflex…

    US, WASHINGTON (ORDO NEWS) — A huge ozone hole has formed over the central part of the Arctic, Nature reports citing data from the NASA Ozone Watch portal. Record-low ozone levels in the central Arctic span an area about three times the size of Greenland. At an altitude of 18 kilometers, scientists recorded a drop in ozone concentration of 90%. As Martin Damerias of the German Aerospace Center emphasized, “this…

    Plant sneezing spreads infections

    US, WASHINGTON (ORDO NEWS) — Wheat leaves, like many other plants, are super-hydrophobic, which reduces the accumulation of dirt and allows water to quickly slide down. Small droplets on such a surface easily merge, and the excess energy of their surface tension turns into kinetic energy, throwing individual droplets away. This mechanism of “sneezing,” or “catapult surface tension,” was described by American scientists in an article published in the Journal…

    US, WASHINGTON (ORDO NEWS) — Physicist Lidia Buruiba of the Massachusetts Institute of Technology conducted an unusual study. In her article, published in the Journal of American Medical Association, she described a model for the distribution of droplets that form during sneezing. The data obtained by Bourguiba differ from the ideas about sneezing that circulate in the scientific community. It turns out that drops of liquid ejected from the mouth…

    Link between BCG vaccination and Covid-19 mortality

    US, WASHINGTON (ORDO NEWS) — Massive tuberculosis vaccination may explain the reduced mortality from coronavirus in some countries. However, there are exceptions to this rule that scientists have not yet figured out. In addition, the biochemical mechanisms of such protection are not known. A group of scientists from the Technological University of New York reported that mortality from Covid-19 infection is inversely correlated with the prevalence of tuberculosis vaccination. An…

    US, WASHINGTON (ORDO NEWS) — Starting with the NASA Mariner 9 Martian mission in the 1970s and to this day, scientists have received a lot of evidence that there could once be ponds on the Red Planet — lakes, rivers, and even oceans. However, how they originated, what they were and why today Mars is a large desert – astronomers continue to speculate and express their assumptions on these topics.…

    US, WASHINGTON (ORDO NEWS) — Scientists from the Franco-British Research University of Cranfield are working on a test that will help determine the presence of SARS-CoV-2 virus particles in wastewater. An article about this was published in the journal Environmental Science & Technology. An analysis of domestic wastewater can provide an efficient and quick prediction of the potential spread of Covid-19 coronavirus pneumonia. The basis of this approach is the…

    US, WASHINGTON (ORDO NEWS) — According to a new study, a relative humidity of 40 to 60 percent in a room can hinder the transmission of SARS-CoV-2. However, scientists warn that the virus can still be transmitted by contact and is stored on the surfaces of objects. The Covid-19 pandemic is still in full swing, and both authorities and scientists are trying to find ways to slow the spread of…

    US, WASHINGTON (ORDO NEWS) — The development of wastewater recycling technologies is associated with epidemiological risks. The content of pathogens, such as noroviruses and adenoviruses, causing gastroenteritis, in such sources can reach ten individuals per liter, while due to the small size (usually 10-300 nanometers), their destruction is difficult. Existing methods of water purification, as a rule, are based on disinfection with ultraviolet and chlorine, however, their effectiveness has been…

    The role of animals in controlling the global viral

    US, WASHINGTON (ORDO NEWS) — The number and variety of viruses on Earth is hard to imagine. Studies of sea water easily bring hundreds of thousands of new species “at a time”: each milliliter of it contains about 10 million viral particles, and many are still not fully understood. Fortunately, these intracellular parasites are highly specialized and rarely infect representatives of different species, especially those quite distant from each other.…

    Black hole weighing 100,000 solar masses discovered

    US, WASHINGTON (ORDO NEWS) — Black holes can only be observed by their effect on nearby objects – for example, by the star with which they rotate in a binary system, or by the radiation of an accretion disk from red-hot material falling into the hole. There are enough examples of such objects with black holes as stellar mass (up to 10 solar masses), and supermassive (millions and billions of…

    US, WASHINGTON (ORDO NEWS) — Relatively small black holes of stellar mass are formed as a result of the collapse of large stars; huge supermassive black holes grow in the centers of entire galaxies. But the black holes of intermediate, average mass (ChDSM) – from 100 to 100 thousand masses of the Sun – remain a mystery. Even their education is actively debated by scientists, although the most popular hypothesis…
