Climate warming could increase malaria risk in cooler regions

Malaria parasites develop faster in mosquitoes at lower temperatures than previously thought, according to researchers at Penn State and the University of Exeter. The findings suggest that even slight climate warming could increase malaria risk to hundreds of thousands, if not millions, of people — including travelers — in areas that are currently too cold for malaria parasites to complete their development.

Spotted lanternfly expert at Penn State offers advice on using tree bands

According to Heather Leach, spotted lanternfly extension associate in Penn State's College of Agricultural Sciences, one of the most effective traps for catching spotted lanternflies is a sticky band wrapped around the trunks of trees. Nymphs and adults are trapped on the sticky barrier as they crawl up the trunks to feed on newer growth higher in the tree.

Seaweed feed additive cuts livestock methane but poses questions

Supplementing cattle feed with seaweed could result in a significant reduction in methane belched by livestock, according to Penn State researchers, but they caution that the practice may not be a realistic strategy to battle climate change.

Report: Pa. employment strong, but job growth leaves regions, industries behind

With the U.S. economy on track for potentially the longest expansion on record after the Great Recession of 2008-09, employment in Pennsylvania overall is strong. But the rosy statewide job numbers can mask persistent decline in various industries and regions across the state, according to economists in Penn State's College of Agricultural Sciences.

Sensing food textures is a matter of pressure

Food's texture affects whether it is eaten, liked or rejected, according to Penn State researchers, who say some people are better at detecting even minor differences in consistency because their tongues can perceive particle sizes.

Ants maintain essential interactions despite environmental flux

Ants adjust their social interactions to accommodate changes in population density, according to researchers at Penn State and Georgetown University. The findings suggest that ant colonies are capable of maintaining their sophisticated social organization despite potentially drastic changes in their environments.

Penn State researchers to boost endangered Chesapeake logperch population

As fishes go, the Chesapeake logperch is hardly impressive.

Annual Penn State Flower Trials is a labor of love for organizers, volunteers

Each May, Sinclair Adam, Alyssa Collins, and a pack of faithful staff and volunteers at Penn State’s Southeast Agricultural Research and Extension Center pull off a logistical — and exhausting — feat, all for the love of flowers.

Hales named director of Penn State Extension

Brent Hales, senior associate dean and chief financial officer of the University of Minnesota Extension, has been named director of Penn State Extension and associate dean in the College of Agricultural Sciences, effective Sept. 3.

New records show spread of parasitic deer flies across the US

With flattened bodies, grabbing forelegs and deciduous wings, deer keds do not look like your typical fly. These parasites of deer — which occasionally bite humans — are more widely distributed across the U.S. than previously thought, according to Penn State entomologists, who caution that deer keds may transmit disease-causing bacteria.

Penn State students take a global look at sustainable agriculture in Costa Rica

A group of Penn State students explored a different type of classroom when they traveled to the tropics over spring break as part of the embedded course “Environmental Resource Management 499: Costa Rica Sustainable Agriculture and Natural Resources,” offered in the College of Agricultural Sciences.

Eastern forests shaped more by Native Americans' burning than climate change

Native Americans' use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a Penn State researcher who determined that forest composition change in the region was caused more by land use than climate change.

Native forest plants rebound when invasive shrubs are removed

Removing invasive shrubs to restore native forest habitat brings a surprising result, according to Penn State researchers, who say desired native understory plants display an unexpected ability and vigor to recolonize open spots.

Protecting pollinators: Penn Staters working to reverse bee population declines

Within the past decade, beekeepers across the globe have observed massive declines in managed honey bee populations. Given their critical role in the nation’s agricultural industry, Penn State’s Christina Grozinger and the Center for Pollinator Research are implementing creative approaches to protecting bee populations in Pennsylvania and beyond.

More than 100 years of data show Pennsylvania tick population shift

The prevalence of the most abundant species of ticks found in Pennsylvania has shifted over the last century, according to Penn State scientists, who analyzed 117 years' worth of specimens and data submitted primarily by residents from around the state.

'Right' cover-crop mix good for both Chesapeake and bottom lines

Planting and growing a strategic mix of cover crops not only reduces the loss of nitrogen from farm fields, protecting water quality in the Chesapeake Bay, but the practice also contributes nitrogen to subsequent cash crops, improving yields, according to researchers.

Songbird-body changes that allow migration may have human health implications

Songbirds that pack on as much as 50 percent of their body weight before migrating and that sleep very little, exhibit altered immune system and tissue-repair function during the journey, which may hold implications for human health, according to Penn State researchers.
