Freeze frame: cracking molecular motion
Time-resolved cryo-electron microscopy can resolve protein motion on millisecond or even microsecond timescales, but the need for highly specialized tools and skills limits the method’s reach.

Interested in how the heart generates contractile forces to pump blood? Then take a look at our new paper "α- and β-myosin II can be non-uniformly distributed within the cardiac sarcomere". #CellBiology www.sciencedirect.com/science/arti...

I am trying to gauge how much interest is given to muscle wasting in critical illness within the scientific community? This is a very heterogenous condition and would be keen on join forces to further understand it!!!

Excited to be part of a consortium application to the European Rare Disease Research Alliance (ERDERA), lead by Coen Ottenheijm (NL). Among the group, I point out @droch.bsky.social, as we seem to be finding ourselves more and more on the same applications. Our methods really pair well together!
