For the first time, MIT chemists measured the energy transfer between photosynthetic light-harvesting proteins. They discovered that the disorganized arrangement of light-harvesting proteins boosts the efficiency of the energy transduction.
The disorganized arrangement of the proteins in light-harvesting complexes is the key to their extreme efficiency.
I found this to be a fascinating read. Wish the paper was linked, but it looks like it's slated to be released in a journal later this week.
