The finding of relatively high levels of the antimicrobial compound clovamide in the leaves of a disease-resistant strain of cacao has significant implications for breeding trees that can tolerate black pod rot, according to Penn State researchers who conducted a novel study.

December 22, 2020

A self-administered "scratch-and-sniff" test for COVID-19 may be around the corner, according to researchers at Penn State, the University of Florida and Arizona State University. The team, which received $912,000 from the National Institutes of Health, will analyze two different smell tests with a goal of developing inexpensive, at-home tests to help identify new cases of COVID-19 and provide a warning sign of a community outbreak in time to thwart it.

December 21, 2020

Bumble bees found in low-quality landscapes — characterized by a relative lack of spring flowers and quality nesting habitat — had higher levels of disease pathogens, as did bumble bees in areas with higher numbers of managed honey bee hives, according to research led by Penn State scientists.

December 16, 2020

Two Penn State botanists have received a grant from Pennsylvania to study wild ginseng population genetics, morphology and human influence through seed planting in the state.

December 14, 2020

The vast majority of nutrients and sediment washed into streams flowing into the Chesapeake Bay are picked up by deluges from severe storms that occur on relatively few days of the year. That is the conclusion of a new study led by Penn State researchers, who say it offers clues for cleaning up the impaired estuary.

December 2, 2020

Shipping pallets — often used as display platforms in retail settings or seen as raw material for household projects — were responsible for sending more than 30,000 people to the emergency rooms of U.S. hospitals over a recent five-year period, according to a new study by a Penn State researcher.

December 2, 2020

Penn State was one of 37 international universities that endorsed a letter drafted by the International Universities Climate Alliance that urged world leaders to protect humankind from climate change.

December 1, 2020

With a $1.7 million grant from the National Science Foundation, Penn State researchers will investigate how duckweed could be grown on Pennsylvania farms to limit nutrient pollution into the Chesapeake Bay.

An inexpensive, FDA-approved drug — cholestyramine — taken in conjunction with an antibiotic prevents the antibiotic from driving antimicrobial resistance, according to new research by scientists at Penn State and the University of Michigan.

Funding from the National Institutes of Health will enable Margherita Cantorna, distinguished professor of molecular immunology and nutrition in the College of Agricultural Sciences, to study whether vitamin D supplementation could help people ward off or reduce symptoms caused by COVID-19.

November 18, 2020

Job losses resulting from the coronavirus pandemic have affected wide swaths of the population, but workers in some demographic groups and industry sectors have been hit harder than others, according to "COVID-19 and Pennsylvania’s Economy," a series of reports compiled by researchers in Penn State's Center for Economic and Community Development.

Biochar — a charcoal-like substance made primarily from agricultural waste products — holds promise for removing emerging contaminants such as pharmaceuticals from treated wastewater. That’s the conclusion of a team of researchers that conducted a novel study.

November 16, 2020

Dairy cows, exposed to drinking water contaminated with heavy metals for a few years, carry more pathogens loaded with antimicrobial-resistance genes able to tolerate and survive various antibiotics. That’s the finding of a team of researchers that conducted a study of two dairy herds in Brazil four years after a dam holding mining waste ruptured, and it spotlights a threat to human health, the researchers contend.

November 11, 2020

Self-reports of smell and taste changes provide earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators, according to an international team of researchers. The researchers also observed a decline in self-reports of smell and taste changes as early as five days after lockdown enforcement, with faster declines reported in countries that adopted the most stringent lockdown measures.

Gold foil, ornate labels and an intriguing backstory are product characteristics highly desired by premium chocolate consumers, according to research conducted by food scientists in Penn State’s College of Agricultural Sciences.

November 9, 2020

Similar to bacteria evolving resistance to antibiotics, viruses can evolve resistance to vaccines, and the evolution of SARS-CoV-2 could undermine the effectiveness of vaccines that are currently under development, according to a paper published Nov. 9 in the open-access journal PLOS Biology by David Kennedy and Andrew Read from Penn State. The authors also offer recommendations to vaccine developers for minimizing the likelihood of this outcome.

The Penn State community is mourning the loss of Philip Keeney, professor emeritus of food science, who died Oct. 17 at the age of 95. Intimately linked with the Department of Food Science since he helped to establish it in 1975, Keeney perhaps was best known for his research and teaching related to ice cream
