Prize motivation: "for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution." Frank developed computational methods to determine the structures of unordered, single molecules, and Dubochet developed a way of protecting the sample by freezing water into a smooth ‘glaze’, rather than crystalline ice.Joachim Frank was born 1940 in Siegen, Germany. He is a former researcher at the European Molecular Biology Laboratory in Heidelberg, Germany, and an honorary professor of biophysics at the University of Lausanne in Switzerland.. He picked the Jet Propulsion lab at Caltech before joining Bob Glaeser, one of the cryo-EM pioneers, at the University of California, Berkeley, and finished his US tour at Cornell University. Electron microscope images provide knowledge that is important for the development of pharmaceuticals, among other things.Tasked with a mission to manage Alfred Nobel's fortune and has ultimate responsibility for fulfilling the intentions of Nobel's will.For more than a century, these academic institutions have worked independently to select Nobel Laureates in each prize category.Several outreach organisations and activities have been developed to inspire generations and disseminate knowledge about the Nobel Prize. Joachim Frank delivered his Nobel Lecture on 8 December 2017 at the Aula Magna, Stockholm University.

All Rights Reserved Nobel Prize in Chemistry, 2017: Molecules of life, captured in 3D And NMR worked for only a relatively small set of proteins.The winners of the 2017 Prize employed three different approaches that together overcame these challenges, taking, as the Nobel Committee said, “biochemistry into a new era, making it easier than ever before to capture images of biomolecules”.Richard Henderson abandoned X-ray crystallography and resorted to imaging proteins using transmission electron microscopy — in which, instead of light, a thin beam of electrons is sent through the specimen.

He also made significant contributions to structure and function of the ribosome from bacteria and eukaryotes. As electron microscopy evolved with better lenses and the development of cryotechnology (in which samples were cooled with liquid nitrogen to about – 190 degrees Celsius in order to shield them from the electron beam) his technique managed to produce, in 1990, a bacteriorhodopsin structure at atomic resolution.Also in 1975, Joachim Frank prepared a theoretical strategy to merge together whatever information is carried in the two-dimensional images from a electron microscope, to generate a high-resolution three-dimensional whole. Jacques Dubochet (born 8 June 1942) is a retired Swiss biophysicist. Scientists’ knowledge evolved steadily over the last six decades — beginning with the pioneering crystallographic studies of the structures of globular proteins that fetched Max F Perutz and John C Kendrew the Chemistry Nobel in 1962, to mastering cryo-electron microscopy (cryo-EM) for which the 2017 Prize has been awarded.In the 50s, X-ray crystallography (exposing protein crystals to X-rays) was used to develop models of biomolecules for research and development; in the 80s, nuclear magnetic resonance (NMR) spectroscopy was also employed to this end. The process of capturing these images in the electron microscope and creating 3D images from them is cryo-electron microscopy, and for its development Joachim Frank, Jacques Dubochet and Richard Henderson received the 2017 Nobel Prize in Chemistry. October 2, 2017 . For the past few months, Joachim Frank, a biophysicist at Columbia, and his wife, Carol Saginaw have been awakened before dawn by their energetic rescue puppy, Daisy. EM requires samples to be held in a vacuum, in which they deteriorate as their water content evaporates.The three laureates began their research in the 1970s. Jacques Dubochet, Joachim Frank and Richard Henderson win the 2017 Nobel prize in chemistry – as it happened. However, crystalline water fuzzed the images as the electron beams were diffracted through water crystals.Dubochet solved the problem by rapid cooling that didn’t allow water molecules to arrange into crystalline form; they instead turned into vitrified water that would act as glass for the electron beam. Biophysicist Joachim Frank was woken up to the news on 4 October 2017 - who will be woken up by the #NobelPrize this year?
