With the 21st Century dawns what many have called the
"biological century," in which advances in biologyspurred by achievements in
genomic research, including the sequencing of the human genomewill bring
revolutionary and unconventional solutions to some of mankindís most pressing
and expensive challenges in health, energy, the environment, and national
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.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
