In this Mmmanuscript we use our new tool M to break a couple of things, as is customary in #cryoEM. Most importantly, we show that 3.7 Å resolution can be achieved for a protein directly inside a cell. Software release next week. Now, thread:

M performs multi-particle refinement. One of single-particle analysis' central assumptions is that the particles are, in fact, single. This is physically never the case, and there is benefit in treating all items in a micrograph/tomogram as a connected system. 
This way deformation occurring during data acquisition can be modeled to improve registration of every particle's motion. Others* have done similar things over the years. M offers a unified framework for these concepts and aligns everything in one go.
