Lawrence Livermore National LabCrossing the Blood Brain Barrier: One Byte at a TimeThe blood-brain-barrier (BBB) is a special structure in the body that helps to protect the brain from unwanted toxins and germs. Unfortunately, this barrier can also make it extremely difficult for therapeutics to reach their intended target within brain. Lawrence Livermore Lab scientists describe how combining experimental techniques with computational methods, making use of some of the fastest supercomputers in the world, can speed up the process of optimizing therapeutics to cross the BBB.

Lawrence Livermore National Lab scientist Sean Ford and teacher Ken Wedel discuss what an earthquake of that size in the Bay Area would look like and explain its effects. Just like an earthquake, a nuclear test can cause seismic disturbances that are recorded at monitoring stations around the world.
