Healthy Living: New supercomputers can simulate beating heart at
cellular level Scientists have created a supercomputer that
mimics a beating human heart, a technology that may one day
revolutionize the way drugs for the heart are created. Cheryl

Laboratory in Northern California, scientists have created
supercomputers -- among the largest in the world -- that can
simulate the human heart all the way down to the cellular level.
"When your heart beats, it's actually an electric signal that
goes around the heart and that causes it to contract," says Fred
Streitz, the director of the National Laboratory's High
Performance Computing Innovation Center. "How that electric
signal transmits around the heart -- we can now model at near
cellular resolution, at real time." Streitz was invited to New
York City for the fourth annual Partner
