Freeze frame microscopy for 3-D biological images captures 2017 Nobel Prize in chemistry
WASHINGTON — Just three years ago, the Nobel Prize in Chemistry went to optical scientists for breaking Abbe's diffraction limit to enable super-resolution microscopy. Today, biomedical microscopy is again in the limelight, with the 2017 Nobel Prize in Chemistry being awarded to Jacques Dubochet, University of Lausanne, Switzerland; Joachim Frank, Columbia University, USA; and Richard Henderson, Cambridge University, UK; "for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution." Using cryo-electron microscopy, researchers can now freeze biomolecules mid-movement and define the structures of their proteins at atomic resolution. This technology has taken biochemistry into a new era.
"The Nobel Committee's recognition of yet another type of biomedical imaging underscores just how important, and enabling imaging and microscopy techniques are to all areas of science and medicine," stated Elizabeth M.C. Hillman, professor of Biomedical Engineering at Radiology, Columbia University, and general chair of the upcoming 2018 OSA BioPhotonics Congress. "The contribution by Drs. Dubochet, Frank and Henderson enables biochemists to image every corner of the cell in atomic detail; a close-up view beyond the reach of optical methods, but an amazing complement to the continuum of optical microscopy and in-vivo optical imaging and tomography methods that are increasingly enriching medical science." The team's work also stands as a testament to the importance of interdisciplinary technique development that spans physics, engineering, biology and chemistry, notes Hillman.
University of California Davis professor and chair of the OSA Microscopy, Histopathology and Analytics topical meeting at the upcoming OSA congress, Richard Levenson, stated, "Cryo-electron microscopy's major breakthrough was to enable imaging of intact cells, frozen in time, without the need for the damaging sample preparation steps required by conventional electron microscopy. Beyond just imaging, the method permits the structure of single proteins to be determined in the context of their native cellular environment." A pathologist by training, Dr. Levenson himself has pioneered methods to simplify and improve microscopic imaging of tissues to tease out tiny details that can betray the presence of disease. "We finally are entering an era where 'seeing is believing,'" says Levenson, "tests that used to rely on biochemical analysis can now visualize molecular events directly. I think the next decade will see a revolution in the way we understand the workings of cells, organs and organisms and the way we use that information in medicine."
The Nobel Prize Award Ceremony will be held on 10 December in Stockholm, Sweden. His Majesty King Carl XVI Gustaf of Sweden will present the honor to Dubochet, Frank and Henderson and the other 2017 Laureates during this annual ceremony.
