A new study used modern methods to reassess a foundational study in biology that explained how ecologically similar species of wood warblers coexist. The research team examined foraging behavior, physical characteristics, diet and evolutionary history of 13 warbler species, including the black-throated green warbler (Setophaga virens) pictured here, and found that how these songbirds coexist is more nuanced than originally proposed.

Foraging on the wing: How can ecologically similar birds live together?

New study uses modern molecular and evolutionary techniques to reassess a foundational, 67-year-old study in warblers.

Immune system proteins involved in severe parasitic disease identified

New insights into the mechanisms that cause more severe cases of schistosomiasis — a disease caused by parasitic worms and second only to malaria in terms of potential harm — have been revealed by researchers at Penn State.

Feeling salty? Increased salt stress reduces tomato pest activity

Increased soil salinity can reduce damage from prominent tomato pests such as the tomato fruitworm, according to researchers at Penn State. They published their findings in the Journal of Plant, Cell and Environment.

Complete genome sequences of six ape species unveiled

Differences among the DNA of seven ape species — including humans — are greater than originally thought, according to an international team led by researchers at Penn State, the National Human Genome Research Institute, and the University of Washington.

Postdoctoral training series assists scholars seeking fellowships

Three free sessions cover funding mechanisms, strategies for crafting effective proposals, and feedback to strengthen current fellowship applications.

Even sublethal insecticide dose may disrupt pollinator mating process

Insecticides can help protect crops against troublesome pests, but they also pose a risk for beneficial insects such as pollinators. A new study led by researchers at Penn State provided insight into how even sublethal doses of insecticides can negatively affect pollinators by disrupting the mating process.
