ClassX Video Lessons Youtube Channel Science Time What The 2019 Nobel Prize Awards in Science Mean For The World
The Nobel Prizes are among the most prestigious awards in the world, established by Alfred Nobel, a Swedish chemist, engineer, and inventor. In 1895, he set up these prizes to honor outstanding contributions in Physics, Chemistry, Physiology or Medicine, Peace, and Literature. Since 1901, these awards have been given annually to recognize groundbreaking achievements that benefit humanity.
In 2019, the Nobel Prize in Physiology or Medicine was awarded to William G. Kaelin Jr., Sir Peter J. Ratcliffe, and Gregg L. Semenza. Their research unveiled how cells sense and adapt to oxygen availability, a crucial process for survival. Oxygen is vital for energy production in cells, as it helps mitochondria convert food into energy. Their work revealed how cells adjust their metabolism when oxygen levels drop, such as during intense exercise. This discovery has opened new avenues for treating diseases like anemia and cancer by targeting how cells respond to oxygen changes.
The Nobel Prize in Physics was shared by James Peebles, Michel Mayor, and Didier Queloz. James Peebles was recognized for his theoretical work in cosmology, which has deepened our understanding of the universe’s origins and structure. Michel Mayor and Didier Queloz made history by discovering the first exoplanet, Pegasi b, orbiting a star similar to our Sun. This discovery confirmed that planets exist beyond our solar system, sparking a new era in the search for Earth-like planets. By the end of 2019, over 4,000 exoplanets had been confirmed, expanding our knowledge of the universe.
John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino received the Nobel Prize in Chemistry for their pioneering work on lithium-ion batteries. These batteries are essential for powering mobile phones, laptops, and electric vehicles. Their invention has paved the way for a more sustainable future by enabling cleaner energy systems and reducing reliance on fossil fuels. Lithium-ion batteries work by moving lithium ions between electrodes, providing a lightweight and efficient energy source.
The 2019 Nobel Prizes in Science highlight remarkable achievements that have transformed our understanding of biology, expanded our view of the cosmos, and advanced technology for a sustainable future. These discoveries not only enhance our knowledge but also offer practical solutions to some of the world’s most pressing challenges.

The greatest benefit to humankind is reflected in the will of Swedish chemist, engineer, and industrialist Alfred Nobel. In 1895, he established five prizes in the fields of Physics, Chemistry, Physiology or Medicine, Peace, and Literature. The prizes were first awarded in 1901 and continue to be presented annually by the Nobel Foundation and the Royal Swedish Academy of Sciences to some of the most accomplished researchers in science.
This year, 15 laureates have been recognized for their achievements. Their work and discoveries range from understanding how cells adapt to changes in oxygen levels to finding the first exoplanet orbiting a sun-like star.
William G. Kaelin Jr., Sir Peter J. Ratcliffe, and Gregg L. Semenza won the 2019 Nobel Prize in Physiology or Medicine for identifying the molecular machinery that regulates gene activity in response to varying oxygen levels. According to the Nobel Assembly, oxygen plays a crucial role in the energy metabolism of living organisms, as it is utilized by mitochondria in nearly all animal cells to convert food into useful energy. Oxygen sensing allows cells to adjust their metabolism to low oxygen levels, such as in our muscles during intense exercise. Other oxygen-controlled adaptive processes include the generation of new blood vessels and the production of red blood cells. The groundbreaking work of these Nobel laureates has significantly advanced our understanding of how different oxygen levels control basic physiological processes, paving the way for promising new strategies to combat anemia, cancer, and various other diseases.
The 2019 Nobel Prize in Physics was awarded jointly to James Peebles for his theoretical discoveries in physical cosmology, and to Michel Mayor and Didier Queloz for their discovery of an exoplanet orbiting a solar-type star. Peebles, from Princeton University, received the award for his theoretical contributions to physical cosmology. Mayor and Queloz, from the University of Geneva and Cambridge University, shared half of the award for discovering the exoplanet named Pegasi b, which was the first planet ever discovered outside our solar system. This groundbreaking find confirmed that planets similar to Earth could exist elsewhere in the universe. As of December 1, 2019, there are 4,135 confirmed exoplanets in 3,073 systems, with 673 systems having more than one planet.
John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino were awarded the 2019 Nobel Prize in Chemistry for their work in developing lightweight rechargeable batteries that power today’s mobile phones and other portable electronic devices. The Nobel Assembly noted that their contributions have laid the foundation for a wireless, fossil fuel-free society. In a lithium-ion battery, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging. These batteries have also enabled the development of cleaner energy systems and electric vehicles, thereby reducing greenhouse gas and particulate emissions.
