A NERSC INCITE projectBridging the Gap between Climate and Weather
The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?

April 2009 Newsletter
In March and April NERSC increased the I/O capabilities of Franklin, added 110 terabytes of storage to the NERSC Global Filesystem, and made upgrades to NERSC's SSH software to improve security and increase the performance of data transfers.
A network performance monitoring tool called PerfSONAR is being used to accelerate big geographically distributed science collabortations such as experiments at the Large Hadron Collider at CERN in Switzerland and the Daya Bay Neutrino Experiment in Southern China. [MORE]

Quantum Secrets of Photosynthesis Revealed
Computational models guide the design of the experiment and help interpret the results
Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key — the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a longstanding mystery that may have finally been solved. The answer lies in quantum mechanical effects.
