Can synthetic clays save a world awash in pollution?
July 21, 2016
In a series of high profile journal articles published over the past 30 years, Sridhar Komarneni has explored ways to remove radioactivity from the environment. A materials scientist and Distinguished Professor of Clay Mineralogy, Komarneni develops specially structured synthetic clays capable of immobilizing radioactive species by ion exchange.
Trees rely on a range of strategies to hunt for nutrient hot spots
July 20, 2016
The precision of the nutrient-seeking strategies that help trees grow in temperate forests may be related to the thickness of the trees' roots and the type of fungi they use, according to David Eissenstat, professor of woody plant physiology, Penn State. The tree must use a variety of strategies because nutrients often collect in pockets -- or hot spots -- in the soil, he added.
Female deer disperse farther than males, present disease-control challenge
June 29, 2016
Fewer female white-tailed deer disperse than males, but when they do, they typically travel more than twice as far, taking much more convoluted paths and covering larger areas. These findings have important deer-management implications in states where chronic wasting disease is known to be infecting wild, free-ranging deer, noted researcher Duane Diefenbach, adjunct professor of wildlife ecology.
Projects to test water for lead, other impurities in underserved Pa. counties
May 20, 2016
Despite the highly publicized lead contamination in the municipal water supply serving Flint, Michigan, the vast majority of public water systems meet federal safe drinking water standards. However, the same cannot be said for private supplies -- such as wells, springs and cisterns -- in Pennsylvania, according to Bryan Swistock, water resources extension specialist in Penn State's College of Agricultural Sciences.
