an award-winning American-Danish trio, including an extremely rare double Nobel

Barry Sharpless, 81, is only the fifth person to win a Nobel twice. He had already won the prize for chemistry in 2001 for his discoveries on the technique of asymmetric catalysis.

They have opened two new fields of modern chemistry: the 2022 Nobel Prize for Chemistry crowned Danish Morten Meldal, American Carolyn Bertozzi and her compatriot Barry Sharpless on Wednesday, who achieved the extremely rare feat of winning a second Nobel. The trio is rewarded.for the development of ‘click chemistry’ and bioorthogonal chemistry“, announced the jury in its ruling.

Barry Sharpless, 81, is only the fifth person to win a Nobel twice. He had already won the prize for chemistry in 2001 for his discoveries on the technique of asymmetric catalysis.

California-based American researcher and Dane Morten Meldal, 58, from the University of Copenhagen, are crowned for their pioneering work on “click chemistry», a new way of combining molecules. This is used in particular to develop pharmaceutical treatments, map DNA or create new materials.

bioorthogonal chemistry

American Carolyn Bertozzi, 55, is celebrated for the invention of bioorthogonal chemistry, a chemical reaction described as capable of being initiated in a living organism, but without disturbing or changing its chemical nature. Cited among this year’s favourites, her discoveries have markedly paved the way for improving the efficacy of cancer treatments.

In science, the Nobel committees had opened the ball by awarding the Nobel Prize in Physiology or Medicine on Monday to Sweden’s Svante Pääbo, father of Denisova man and discoverer of Neanderthal man’s DNA. On Tuesday, the Franco-Austro-American trio of Alain Aspect, Anton Zeilinger and John Clauser, pioneers of the revolutionary “quantum entanglementHe had received the Nobel Prize in Physics.

The prize is endowed with 10 million Swedish crowns (approximately 920,000 euros) in each discipline, possibly to be shared in the case of co-winners. The week continues with the Nobel Prize for Literature on Thursday and the Nobel Peace Prize, awarded in Oslo. The Nobel Prize ceremony ends next Monday with the Nobel Prize in Economics.
