Bean plants that suppress secondary root growth in favor of boosting primary root growth forage greater soil volume to acquire phosphorus, according to Penn State researchers, who say their recent findings have implications for plant breeders and improving crop productivity in nutrient-poor soils.

Food safety practices that Americans take for granted — washing hands with soap, refrigeration, and not cutting raw meat and vegetables on the same surface without disinfection — are not widely practiced in other places around the world, and researchers in Penn State's College of Agricultural Sciences want to change that.

For more than a century, plant geneticists have been studying maize as a model system to understand the rules governing the inheritance of traits, and a team of researchers recently unveiled a previously unknown mechanism that triggers gene silencing in corn.

Mushrooms may contain unusually high amounts of two antioxidants that some scientists suggest could help fight aging and bolster health, according to a team of Penn State researchers.

With amphibian populations declining around the world and funds to find the causes scarce, a team of Penn State researchers has shown that an unorthodox tactic will make it easier and therefore less expensive to capture adult salamanders and frogs.

A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets — planets beyond our solar system. With the new attachment, ground-based telescopes can produce measurements of light intensity that rival the highest quality photometric observations from space. Penn State astronomers, in close collaboration with the nanofabrication labs at RPC Photonics…

Some great ideas are born out of years of painstaking research. Others are gleaned from the plotline of the movie "Twister."

There is considerable uncertainty surrounding emerging contaminants in aquatic ecosystems and groundwater, and a recent Penn State study of compounds from pharmaceuticals and personal care products didn't add much clarity. But it did provide insight into the transport of the chemicals, according to researchers in the College of Agricultural Sciences.
