In case anyone wants to know what Ken is up to…
This article is an awesome layman’s breakdown of why Ken was whisked away to San Francisco only after having been in Hamburg for 3 weeks. He has beam time for the next three days from 9pm to 9am (sucks!) so feel free to text him a happy message while you’re at the bar!

image description: The molecular structure of proteins is inferred by measurements of patterns of X-rays scattered from crystals formed from those proteins. The regular array of molecules in the crystal gives rise to strong peaks needed for measurement, shown here as balls in a three-dimensional space.

Just to add my two cents, the proteins we are studying are photosystem I and photosystem II, which are important in making photosynthesis work.
Here is a wiki page on it : http://en.wikipedia.org/wiki/Photosynthesis (see the bit on light reactions)
