![Infographic on the 2022 Nobel Prize in Chemistry, awarded jointly to Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless for their development of click chemistry and bioorthogonal chemistry. Click chemistry refers to reactions which efficiently snap together small molecules with simple reaction conditions and no unwanted byproducts. Bioorthogonal chemistry involves chemical reactions which happen in cells without affecting their normal chemistry. The graphic shows a classic example of a click chemistry reaction involving the cycloaddition of an azide and an alkyne using a copper catalyst, and also how this was adapted for use in living organisms by removing the copper catalyst and replacing the alkyne with a cycloalkyne.](https://i0.wp.com/www.compoundchem.com/wp-content/uploads/2022/10/2022-Nobel-Prize-in-Chemistry.png?resize=370%2C208&ssl=1)

The 2021 Nobel Prize in Physics was awarded to Syukuro Manabe and Klaus Hasselmann “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”, and to Giorgio Parisi “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

The second of the science Nobel Prizes awarded this year was in Physics. The Nobel Prize in Physics 2020 was awarded with one half to Roger Penrose, “for the discovery that black hole formation is a robust prediction of the general theory of relativity”, and the other half jointly to Reinhard Genzel and Andrea Ghez “for the discovery of a supermassive compact object at the centre of our galaxy”.
