What's My Story: Ph.D. Research Assistant in Chemistry

It took Tana Villafana some time to figure out that she wanted to be a chemist. She started out hoping to be a writer and a musician. But as things worked out, she got to combine her love of the humanities with her love of electromagnetism.

Ph.D. Research Assistant: employed by a university to conduct research while seeking to earn a doctorate degree. They are typically responsible to a principal investigator.

Fish Tagging

Ecosystems have limits to the numbers of organisms and population sizes they can support. These limits are set by predation, competition, diseases and the physical habitat (reefs, artificial reefs, mud flats, sea grass, and marsh). Fish biologists are using two types of tagging to understand how the physical environment constrains the population dynamics of the red drum, North Carolina's state fish.

Riding the Wind

From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. Those forces have both strength and direction and they can be observed and measured to predict future motion. Watch how an aeronautics engineer works with Newton's three Laws of Motion to test the best posture and helmet for a cyclist in a wind tunnel.

Surging Water Warnings

Storm surge is not a giant wave like a tsunami, but it is the gradual piling up of water along the coast. It is often the most damaging effect of a hurricane, but is not often clearly understood and it is not easy to predict. New research, and a new computer program developed by the UNC Institute of Marine Science, is helping solve the problem.

Exploration Station

Maria Lundberg takes us to downtown Lumberton to visit Exploration Station, a regional children's museum designed to help youngsters open their minds to creativity through 12 interactive exhibits that focus on literacy, science, math, arts, health and safety. Exploration Station is the only museum of its kind in Robeson County and receives visitors from North and South Carolina. Original Broadcast Date: 05/17/2013
