2019 Nobel Prize in Medicine

2019 Nobel Prize in Medicine: has been awarded jointly to William G. Kaelin Jr, Sir Peter J. Ratcliffe and Gregg L. Semenza 
“for their discoveries of how cells sense and adapt to oxygen availability.”
•The oxygen-sensing ability of the body has a role in the immune system and the earliest stages of development inside the womb. 
•If oxygen levels are low, it can trigger the production of red blood cells or the construction of blood vessels to remedy this. 
•More red blood cells mean the body is able to carry more oxygen and is why athletes train at altitude.
Alfred Nobel, a Swedish chemist, engineer, industrialist, and the inventor of dynamite, in his last will and testament in 1895, gave the largest share of his fortune to a series of prizes in Physics, Chemistry, Physiology/Medicine, Literature, and Peace, to be called the “Nobel Prizes”.
•In 1968, the sixth award, the Prize in Economic Sciences was started.
