    Unicorn Black Hole

    • It is possibly the smallest-known black hole in the Milky Way galaxy and the closest to the solar system.
      • The black hole is located about 1,500 light years (the distance light travels in a year, 9.5 trillion km) from Earth.
    • It is roughly three times the mass of the sun.
    • A luminous star called a red giant orbits with the black hole in a so-called binary star system named V723 Mon.
    • Black holes are electromagnetically dark so they are difficult to find. However, tidal distortion on the companion star of Unicorn indicated its presence.
      • Its strong gravity alters the shape of the companion star in a phenomenon known as tidal distortion, making it elongated rather than spherical and causes its light to change as it moves along its orbital path.

    Oxygen Concentrators

    • An oxygen concentrator or generator is a device recommended by doctors to fulfill the shortage of oxygen and it functions with the help of atmospheric air and electricity
      • The oxygen concentrator takes in this air, filters it through a sieve, releases the nitrogen back into the air, and works on the remaining oxygen.
    • Oxygen concentrators are the easiest alternatives to cylinders but can only supply 5-10 litres of oxygen per minute (critical patients may need 40-50 litres per minute) and are best suited for moderately ill patients.
    • An oxygen concentrator can only be used under medical supervision and prescription and it should not be considered as a treatment for COVID-19.

    Deep Time Project

    • Scientists at the Human Adaption Institute leading the 1.2 million-euro (US$1.5 million) “Deep Time” Project.
    • Under the Project, Eight men and seven women lived for 40 days in the dark, damp depths of the Lombrives cave in the Pyrenees southwestern France. 
    • There was no sunlight inside, the temperature was 10 degrees Celsius (50 F) and the relative humidity stood at 100 percent
    • The cave dwellers had no contact with the outside world, no updates on the pandemic nor any communications with friends or family.
    • The project aimed to test how people respond to losing their sense of time and space.
    • It will help scientists to better understand how people adapt to drastic changes in living conditions and environments.
