Microorganisms that grow in impossible conditions

Extremophiles

Microorganisms that prefer to grow in those conditions where life is impractical are called extremophiles.

No doubt, our earth is full of diversity in both flora and fauna, but in earlier times, it was considered silly to expect that any organism could flourish in so tough conditions, but fact is fact and it is true that there are organisms that are able to live at-
  1. Extremely high temperature (Thermophile or Hyperthermophile)
  2. High pressure (Piezophile)
  3. Highly acidic atmosphere (Acidophile)
  4. Highly basic atmosphere(Alkaliphile)
  5. High concentration of heavy metal in the solution (Metallotolrant)
  6. Can resist high levels of ionizing radiations (Radioresistant)
  7. Remain alive from extremely long times under the rocks at low temperature (Cryophile or Polycryophile)
  8. High concentrations of salt (halophile)
  9. High concentrations of sugar (Osmophile)
  10. Polyextremophile, which are capable of growing in various extremophile conditions
  11. Thermoacidophile who can live at high extreme temperature and high acidity
  12. Grow in oxygen less atmosphere (anaerobe)
  13. Lithoautotroph, which live on the carbon extracted from CO2 and exergonic inorganic oxidation
  14. Nutrition less atmosphere (Oligotroph)
  15. Extremely dry conditions (Xerophile)

These facts show that it is not surprising to find some type of microorganism at a place where everything dies.

The most Gruesome and filthy tortures invented in human history

Image
Most Brutal tortures in the history Impalement Invented in                                       -     Romania Time Taken by the victim to die   -     15 min to 3 days Brief description                             -     This was considered the most inhumane way of torture ever adopted in the history. For Impaling a victim, a tapered and oiled wooden stake is inserted inside the anus (in case of men) or in vagina (for women) from the pointed side. After this, it is stood in the vertical position so that the stake is inserted slowly with the own wait of the victim over a long period of time. The punishment was carried out until the stake comes out of the victim’s breast, shoulder, stomach or mouth. The cruelest part of this torture was that the pointed end was kept blunt enough to not kill the victim too early, so that he/she would have to endure the pain for several hours or even days before dying.

World's first analog computer

Image
Antikythera mechanism It is the oldest gear system found till date and is also famous as the oldest analog computer of the world. the calculator has been dated to be built in 1st century BC. The mechanism was found in 1900-1901 from a shipwreck off the coast of the Greek island of Antikythera and is of Greek origin. No other older artifact showing so much complex mechanism was ever found after that, hence Antikythera mechanism is of great historical significance. Reconstruction of Antikythera mechanism at Archaeological museum Athens It is actually a date calculator which was used as a calendar. The calculator had a small hand crank which is lost now. The hand crank was used to set the date and was linked to the largest gear through a crown gear. When the hand crank was rotated, all the gears inside were also rotated with it and various astronomical figures like position of the Sun, Moon phases, planets and eclipse cycles were calculated. The mechanism was made with

Milestones of Human evolution

Image
Milestones of Human evolution Theory of evolution states that we humans, like all other living species of the world have evolved from our ancestors. It is stated that a genetic mutation occurred in few members of an old species of chimpanzee and they were evolved into a newer species. This phenomenon continued for millions of years and we as humans were evolved finally. No doubt this phenomenon still continues and there are a lot of developments to happen. Well this post will only emphasize on the major milestones which occurred in our history of evolution. Toumai (Sahelanthropus) Believed to have existed 7 million years ago, this species is considered to have first evolved from chimpanzees. In this context they are the first known step in our evolution. For detailed information you may jump to Sahelanthropus which contains the detailed text about the species. Orrorin (Orrorin tugenesis) It is considered as the second big step in our evolution and is believed to
