Landscape architecture professor receives Stuckeman Collaborative Research Grant

April 22, 2024

Stormwater runoff has become one of the leading causes of water pollution in urban environments, according to the U.S. Environmental Protection Agency, due to years of cities implementing “gray” infrastructure. Stuart Echols, associate professor of landscape architecture in the Stuckeman School, is working to rectify this with the support of the recently awarded 2024 Stuckeman Fund for Collaborative Design Research Grant for $50,000 over the course of two years.

April 5, 2024

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. 

Vaccine protects cattle from bovine tuberculosis, may eliminate disease

March 28, 2024

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.

Novel method to measure root depth may lead to more resilient crops

March 19, 2024

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.

Forest, stream habitats keep energy exchanges in balance, global team finds

March 13, 2024

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.

Cyber-physical heating system may protect apple blossoms in orchards

February 28, 2024

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.

Stable profits, land preservation matter to farmers debating solar leases

February 12, 2024

While a stable and predictable profit is an important factor to Pennsylvania farmers considering leasing out their land for solar energy development, it’s not enough on its own, according to a new study led by Penn State researchers.

Sugar-reduced chocolate with oat flour just as tasty as original, study finds

February 12, 2024

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.
