Invasive species cause billions in damages every year

  • Disease-carrying mosquitoes, crop-ravaging rodents, forest-eating insects and even the domestic cat are all causing damages to humans and environment, according to a newstudy.
  • Researchers estimate that invasive species have cost nearly $1.3 trillion dollars to the global economy since 1970, an average of $26.8 billion per year. And they warn that this is likely an underestimate.
  • Most of the price tag is associated with the damage to ecosystems, crops or fisheries, although pest-control measures were also included in the research.
  • The top ten invasive pests includes crop-eating rats and the Asian gypsy moth, which is attacking trees throughout the northern hemisphere.

Temperature difference in respiratory tract influences SARS-CoV-2 replication

  • Natural temperature differences which exist in the upper and lower respiratory tract influence the replication of the novel coronavirus and the subsequent activation of the immune system, says a new study.
  • The study assessed the growth of the novel coronavirus SARS-CoV-2, and activation of the immune system's cellular defence mechanisms.
  • In the research, scientists compared the infection pathways of the novel coronavirus and the 2002-03 SARS-CoV pandemic virus in special cell cultures mimicking the respiratory tract.
  • While the 2002-03 pandemic virus is characterized by severe disease and inflammation in the lower respiratory tract.

Scientists discover X-rays from Uranus

  • Astronomers have detected X-Rays from Uranus using Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.
  • Since Voyager 2 was the only spacecraft to ever fly by Uranus, astronomers currently rely on telescopes like Chandra and the Hubble Space Telescope to learn about this distant and cold planet that is made up almost entirely of hydrogen and helium.
  • In the new study, researchers used Chandra observations taken in Uranus in 2002 and then again in 2017. They saw a clear detection of X-rays from the first observation, just analysed recently, and a possible flare of X-rays in those obtained fifteen years later.
