High-tunnel growing systems, sometimes called hoophouses, have gained popularity for their ability to enhance growth conditions and extend the growing season of horticultural crops. Now, a team led by Penn State researchers has demonstrated that growers can select various plastic film coverings on the structures — depending on their desired light-filtering properties — to protect plants and enhance their health.

Antimicrobial resistance is an increasingly serious threat for public health, and the use of antimicrobials in livestock feed has been a major contributing factor in the emergence and spread of antimicrobial resistance to many drugs, according to the U.S. National Institutes of Health. Led by Erika Ganda, assistant professor of food animal microbiomes, a Penn State research team conducted a study of natural feed additives that are promising alternatives to substitute for antimicrobial growth promoters.

The size of an individual snack piece not only influences how fast a person eats it, but also how much of it they eat, according to a new study led by researchers at Penn State. With nearly a quarter of daily calorie intake in the United States coming from snacks, these findings may have implications for helping people better understand how eating behavior impacts calorie and sodium intake.

Bovine tuberculosis (TB) is a livestock disease that results in large economic losses to animal agriculture worldwide. The disease can also transmit to humans and cause severe illness and death. Researchers from Penn State, Addis Ababa University and the University of Cambridge have now demonstrated that a vaccine for TB currently used in humans significantly reduces infectiousness of vaccinated livestock, improving prospects for elimination and control. The study published today (March 28) in the journal Science.

As climate change worsens global drought conditions, hindering crop production, the search for ways to capture and store atmospheric carbon causing the phenomenon has intensified. Penn State researchers have developed a new high-tech tool that could spur changes in how crops withstand drought, acquire nitrogen and store carbon deeper in soil.

Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team led by Penn State researchers has now found that these ecosystems appear to keep the energy exchanges in balance — a finding that the scientists called surprising.

A newly developed intranasal vaccine candidate, called SpyCage, helps to clear COVID-19 infections more quickly than controls in pre-clinical testing, according to a recent study led by researchers at Penn State.

March 11, 2024

Penn State researchers examined community member's COVID-19 perceptions in Bristol Bay, Alaska, home to the world’s largest commercial salmon fishery, and found perceptions of risk varied across race/ethnicity groups by residency and income.

March 8, 2024

A new study led by researchers at Penn State has clarified how a widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm. These findings could improve techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.

Synthesized from cholesterol in the liver, bile acids long have been known to play a role in human metabolism. A team led by Penn State researchers has uncovered the mechanism by which bacteria in the gut generate a wide variety of new bile acid species, the functions of which are not yet clear.

Spring frosts can have devastating effects on apple production, and a warming climate may be causing trees to blossom early, making them more susceptible to the damaging effects of extreme cold events. Growers’ attempts to prevent the flowers from freezing by attempting to heat the canopies of their orchards largely have been inefficient. To deal with the worsening problem, Penn State researchers devised a frost protection cyber-physical system, which makes heating decisions based on real-time temperature and wind-direction data.

TerraSafe has established a lab in State College and entered a licensing agreement with Penn State to commercialize sustainable packaging solutions developed by researchers at Penn State. The agreement is based on technologies invented by a research team led by Jeffrey Catchmark, professor of agricultural and biological engineering and of bioethics in the College of Agricultural Sciences. Catchmark and his team have worked for years developing technology that can replace conventionally used materials with those that are significantly more environmentally friendly.

Kathleen Keller, professor of nutritional sciences and food science at Penn State, will deliver the 2024 Pattishall Research Lecture on March 20. Her lecture will discuss brain and behavioral factors that drive what, why and how children eat, and how these eating behaviors predict the development of childhood obesity.

February 22, 2024

A team of researchers led by Sara Hermann, assistant professor of arthropod ecology and trophic interactions in the Penn State College of Agricultural Sciences, has developed pest control tools based on chemicals present in interactions between ladybugs and aphids. These tools could offer farmers more sustainable pest-control options.

The secret to making delicious chocolate with less added sugar is oat flour, according to a new study by Penn State researchers. In a blind taste test, recently published in the Journal of Food Science, 25% reduced-sugar chocolates made with oat flour were rated equally, and in some cases preferred, to regular chocolate. The findings provide a new option for decreasing chocolate’s sugar content while maintaining its texture and flavor.

Spicy food lovers know that milk can ease the oral burn, but why? Some believe that fat is the soother, with whole cow’s milk reducing the bite more than low-fat cow’s milk or plant milks. A new study conducted by Penn State food scientists, however, suggests that protein plays a role in cooling the heat sensation, too.
