ABCnews is carrying this story about a remarkable discovery in great white shark research. By using new tracking technology, scientists followed the movements of a great white named "Nicole" over a 12,000 mile journey from Africa to Austrialia. They also tracked a group of salmon sharks moving from Alaska to Hawaii. The finds have implications not only in the study of the sharks and how to develop conservation plans for them, but the way the sharks traveled could also help certain kinds of medical research.
