In Disease Outbreak Management, Flexibility Can Save Lives and Money
In Disease Outbreak Management, Flexibility Can Save  Lives and Money 21 October 2014A new approach for responding to and managing disease outbreaks is being proposed by a team of epidemiologists led by two Penn State University researchers. The team's flexible approach could save many lives and millions of dollars.
Greater Rates of Mitochondrial Mutations Discovered in Children Born to Older Mothers
Greater Rates of Mitochondrial Mutations Discovered in Children Born to Older Mothers 13 October 2014The discovery of a "maternal age effect" by a team of Penn State scientists that could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells -- and the transmission of these mutations to children -- could provide valuable insights for genetic counseling. These mutations cause more than 200 diseases and contribute to others such as diabetes, cancer, Parkinson's disease, and Alzheimer's disease. The study found greater rates of the mitochondrial DNA variants in children born to older mothers, as well as in the mothers themselves. The research will be published in the early online edition of the Proceedings of the National Academy of Sciences on October 13, 2014.
Predicting the Future of Antarctic Ice
Predicting the Future of Antarctic Ice 30 September 2014The National Science Foundation's Division of Mathematical Sciences has awarded more than $500,000 to Penn State to develop new statistical methods needed for predicting the future of Antarctic ice sheets. Using information gleaned from geologic data from the past 20,000 years, the scientists also will apply their new methods to provide a better understanding of the past and current behavior of the ice sheets.
