New cryo-electron microscope produces first beam

The cryo-electron microscope installed on the Imperial College London Hammersmith Campus produces its first beam, coinciding, fittingly, with the award of the 2017 Nobel Prize in Chemistry, to Jacques Dubochet, Joachim Franck and Richard Henderson, “for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution.”

London research consortium for cryo-EM awarded £3 million

The London consortium for cryo-EM (LonCEM), of which the The DNA Replication Group is a founding member, awarded £3 million to establish a new, state-of-the-art cryo-EM facility at the Francis Crick Institute. The award is part of a larger £20 million investment by the Wellcome Trust in cryo-electron microscopy to support world-leading structural biologists across the United Kingdom.
