Researchers watch protein 'quake' after chemical bond break

Scientists for the first time have precisely measured a protein's natural 'knee-jerk' reaction to the breaking of a chemical bond -- a quaking motion that propagated through the protein at the speed of sound.

For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data. All of the assumptions were proven false by Dr. Alla Zelenyuk and her colleagues.
