A celebration of cryo-EM

Here at Nature Methods, we were quite excited yesterday to wake up to the news that the Nobel Prize in Chemistry had been awarded to Jacques Dubochet, Joachim Frank, and Richard Henderson for their seminal developments in cryo-electron microscopy (better known as cryo-EM) which now enable high-resolution biomolecule structure determination. This is a technique we have been watching closely since 2013, when the first papers (including one of our own) realizing the capability of near-atomic-resolution structure determination with cryo-EM were published.

Though much of the excitement about cryo-EM is quite recent, the Nobel Prize is a good reminder to us all that the essential foundations of this technology were laid decades ago. We celebrated such developments, both old and new, in our 2015 Method of the Year issue featuring cryo-EM.

To commemorate this well-deserved Nobel Prize, Nature Research presents an editorially curated collection of papers published in our pages – including methods and protocols, biological results generated using cryo-EM technology, and reviews, news and comment. Check it out!

An archive for raw EM data

Earlier this week we published a Correspondence describing EMPIAR, a public archive for raw 2D electron microscopy (EM) image data.

While the established Electron Microscopy Data Bank (EMDB) hosts the 3D EM map data required by most journals for publication, the EM community has long been calling for an archive to host the raw 2D image data underlying the 3D maps, as highlighted in our Method of the Year 2015 feature. EMPIAR, a pilot project from the Protein Data Bank in Europe (PDBe), now fills this need.

At Nature Methods we support this archive as a welcome development in the rapidly growing 3D EM field that will enhance transparency, reproducibility, and facilitate the development and refinement of data analysis tools. Though we do not require that our authors deposit their 2D EM image data in EMPIAR, we do encourage it. We urge researchers to make use of the archive and provide feedback to the developers in order to ensure that it is meeting the needs of the field.
