Drs. Fenton and Cherry Honored by NSF and Science

Drs. Flavio Fenton and Elizabeth Cherry of the Department of Biomedical Sciences in the College of Veterinary Medicine have been awarded honorable mention in the interactive media category of the Science and Engineering Visualization Challenge created by the National Science Foundation (NSF) and the journal Science. Their winning contribution, "Cardiac Bioelectricity and Arrhythmias," has been published in a special section of the September 22, 2006 issue of Science and Science Online and on the NSF website.

Drs. Fenton and Cherry, who have been studying mechanisms of heart rhythm disorders for more than ten years, developed their interactive program to educate people about such disorders. In normal hearts a region of pacemaker cells sends out electrical waves that keep the heart pumping rhythmically, supplying life-giving oxygen to the body. When these electrical waves become disorganized, the heart starts beating irregularly or arrhythmically, which produces symptoms ranging from dizziness to unconsciousness to death. "Cardiac Bioelectricity and Arrhythmias" presents detailed information on cardiac anatomy, normal cardiac electrophysiology and different kinds of arrhythmias using a combination of words, pictures, and interactive computer simulations and animations.

If you don't know your aorta from your elbow, try the "Heart Anatomy" section, (tick the boxes).

But what animates the heart before it develops? what is the driving force behind those first pulses evident long before the heart develops? What causes circulation to begin inside a fertilised birds egg?

A clue comes from the fertilization of barnacles with seawater.
