Emory University News Release . It is a new found species of copepod, a tiny aquatic crustacean. Ga. Copepods are microcrustaceans, among the thousands of crustacean species that can be found in marine and freshwater environments. They are the most abundant multi-celled organisms in the world, and form an important part of plankton communities, the foundation for the food chain that leads up to much larger fish and whales.

Color image produced by researchers shows a spiral heart wave.
Victims die within minutes unless the erratic heart rhythms can be halted with massive jolts of electricity from a defibrillator. Medical researchers have now moved one step closer to understanding the causes of ventricular fibrillation through a remarkable series of high-resolution movies that clearly show how the condition disrupts the electrical signals that normally govern the heart. The unique high-speed imaging system built for the study also revealed for the first time that ventricular fibrillation may develop in two distinct phases. This dramatically increases the possibility that we could develop a new defibrillator or improve existing defibrillators. Georgia Tech Research News .
