Study of Earth's Ionosphere Could Improve GPS Communications


Researchers from NASA’s Jet Propulsion Laboratory along with Canada’s University of New Brunswick are conducting a joint research project to look for and study interference producing irregularities in the Earth's ionosphere that can affect the Global Positioning System. Dr. Richard Langley from the University of New Brunswick, Canada is a member of the research team. He'll tell us about what he and his colleagues hope to learn from this project. Also… Greg Flakus reports on a cyber-security conference that was recently held in Houston, Texas. Attendees discussed what’s being done to counter threats from cyber intrusions. Jessica Berman tells us that researchers are hoping that a drug now used to treat seizures can improve memory in the early stages of Alzheimer's, even reversing the condition.
