History of Dinosaurs and cause of their extinction - The Jurassic era of our earth

Image
  It is the story of the time when on our earth the dinosaurs used to live. It is about 65 million years ago the giant dinosaurs roaming in grasslands and these battleship size creatures dominate the skies. The mammals of that era were very small they were not like today’s rhinos; hippopotamus as they were not evolved because the big chunk of food was consumed by mighty dinosaurs.  With time these mighty creatures became extinct, what had happened to these creatures and what killed dinosaurs and what is history of dinosaurs the researchers are working hard to find these answers. Here are possible causes for the extinction of these huge size creatures. The time in which dinosaurs were alive is known as the Mesozoic era. This long time frame is divided into three periods. First was a Triassic period, second the Jurassic period, third the cretaceous period. The Triassic period was 250 – 200 million years ago the interesting thing of that period was the earth has only one continent c

New South African Strain of Corona Virus can reduce efficacy of Pfizer vaccine

  THE NEW MUTATED FORM OF COVID 19 COULD DECREASE THE EFFECTIVENESS OF VACCINES.   New South African strain of covid 19 could decrease the effectiveness of Pfizer / bio n tech vaccine. This is revealed   in the research in Israel. The research is conducted on the persons who have taken the single or a double dose of the vaccine and then data is compared with the patients of covid 19.   The persons who have taken a double dose of the vaccine were infected eight times higher than the persons who were not vaccinated. According to the researchers, the South African strain of covid 19 could decrease the effectiveness of the vaccine. The results are alarming but the good thing about the new strain is that it does not spread quickly as other strains of covid 19 do. According to researchers new South African strain can decrease the efficacy of vaccine but this vaccine can stop covid 19 to spread in exponential numbers.   Although Pfizer had not issued any statement about this research t

How corona virus destroy human immune system

  How corona virus destroy human immune system: One drop of saliva contains almost 200000 corona virus particles. Corona virus does not have floating ability but it can combine with dust particles and in that way it can float for hours. It is estimated this virus has the ability to retain on the glass surface for 96 hours, on plastic and steel surface it retains for about 72 hours, and on cardboard 24 hours. Mostly corona virus attack on lungs because the lung cells have H 2 receptors and corona virus has spike on its surface. In simple words if the H 2  receptor of lung cell is lock then spike protein or spike  of corona virus is key. That’s why it infect mostly lungs cell as cells of other body organs does not possess H 2 receptors. Our cell membrane is selectively permeable which means only selective or beneficial particles (nutrients etc) can pass through it, but spikes of corona virus cheat security system of membrane and enter into the cell where it start creating millions of it
