Troy Ott, professor of reproductive physiology in the College of Agricultural Sciences, is developing a blood test that dairy farmers and livestock veterinarians can use to tell whether a cow failed to conceive after insemination.
Communities with more self-employed workers can better withstand economic shifts caused by imports than communities that have fewer self-employed people, according to Penn State economists.
A new Penn State project aimed at improving the food system in East Africa by enhancing pollination services and promoting bee-derived products has received a Food Systems Innovation Grant from the Global Center for Food Systems Innovation, based at Michigan State University.
Chemical signaling among social insects, such as bees, ants and wasps, is more complex than previously thought, according to researchers at Penn State and Tel Aviv University, whose results refute the idea that a single group of chemicals controls reproduction across numerous species.
Scientists had high hopes that heroin would be a safer and less addictive alternative to morphine, which had left tens of thousands of soldiers dependent on it after the Civil War. At the dawn of the 20th century, philanthropic societies even dispensed free samples of heroin to morphine addicts. Unfortunately, the wonder drug, when injected, turned out to be two to four times more potent than morphine and highly addictive.
Food Science Professor Gregory R. Ziegler is exploring the commercial potential of a brilliant orange found in avocado pits as a natural food coloring.
Penn State researchers are conducting field studies to monitor the effects wastewater irrigation practices are having on the ponds and its froggy inhabitants. The Living Filter has been operational for more than 50 years and is used as a cost-effective, sustainable way to restore ground-water levels and meet pollution-control requirements.
Smartphones are so ubiquitous, and text messaging and social media activities so common in public places, that no one questions what anyone does with their phone. That pervasiveness allows a phone application to be used in direct, concealed observations without alerting the people being observed.
In the battle against weeds, tillage is one of the strongest weapons at the disposal of organic or ecologically based farmers. But, depending on when it is used, tillage can also be a strong driver of nitrogen losses that contribute to groundwater pollution, according to researchers in Penn State's College of Agricultural Sciences.
Exploring the effects of environmental stress and policy strategies for building more resilient communities in the central Asian highlands is the focus of a new NASA-funded research project at Penn State.
More than 48 million turkeys and laying hens in 21 states have died this year following an outbreak of highly pathogenic H5N2 avian influenza. As wild waterfowl, which may carry the virus, begin their autumn migration, Pennsylvania is in the crosshairs, and that has Penn State's Animal Diagnostic Laboratory on high alert.
Adolescents who live in rural areas and small towns and cities are more likely to abuse prescription painkillers than adolescents who live in large urban areas, according to sociologists.
Scientists wonder why some people get so sick and even die after being infected by the foodborne pathogen E.coli O157:H7, while others experience much milder symptoms and recover relatively quickly. Now Penn State's College of Agricultural Sciences researchers believe they have discovered an explanation.
Penn State researchers assessed the effects of changing climate conditions on agriculture, tourism, infrastructure, water resources, forestry, energy and human health in the 2015 Pennsylvania Climate Impact Assessment Update. Researchers also made recommendations to help Pennsylvanians prepare and respond.
In a deception that likely has evolved over thousands of years, a caterpillar that feeds on corn leaves induces the plant to turn off its defenses against insect predators, allowing the caterpillar to eat more and grow faster, according to chemical ecologists in Penn State's College of Agricultural Sciences.
John Hayes, associate professor of food science and director of Penn State's Sensory Evaluation Center, received the Young Investigator Award at the Pangborn Sensory Science Symposium in Gothenburg, Sweden.
Compounds found in purple potatoes may help kill colon cancer stem cells and limit the spread of the cancer, according to a team of researchers.
When trying to explain the potential effects of climate change on plants, fish and wildlife, scientists usually resort to language that fails to convey the impact of warming. Now, a study by Penn State's College of Agricultural Sciences fisheries researchers clearly explains the impact of projected warming waters on wild brook trout in the eastern U.S. for fishermen.
Matthew Kaplan, professor of intergenerational programs and aging in Penn State's College of Agricultural Sciences, is the co-recipient of the Brabazon Award for Evaluation Research, Generations United recently announced.
The growing availability of heroin, combined with programs aimed at curbing prescription painkiller abuse, may be changing the face of opiate addiction in the U.S., according to sociologists.
