HGSAC prepares for largest Life Sciences Symposium yet

The Life Sciences Symposium, organized by the Huck Graduate Student Advisory Committee (HGSAC), is set to showcase student research on May 23.

Heather Hines named interim director of the Center for Pollinator Research and the Insect Biodiversity Center

Heather Hines, Associate Professor of Biology and Entomology, has been named Interim Director of the Center for Pollinator Research (CPR) and the Insect Biodiversity Center (IBC). Hines is succeeding Christina Grozinger, Publius Vergilius Maro Professor of Entomology and director of the Huck Institutes of the Life Sciences.

This study is the first to scientifically document use of ghost pipe in North America, along with the growing influence of social media and the internet on how and why people are turning to ghost pipe as a medicinal plant. Credit: Penn State. Creative Commons

Traditional forest medicinal plant ghost pipe used differently today

Driven by the internet and social media, consumption of a strange white plant known as ghost pipe is enjoying a resurgence — but with a twist.

High-tech sticker can identify real human emotions

A team led by scientists at Penn State has created a stretchable, rechargeable sticker that can detect real emotions — by measuring things like skin temperature and heart rate — even when users put on a brave face.

The study found that the presence of the nearby Lake Tanganyika, pictured here, plays a considerable role in shaping cholera transmission in the area.  Credit: MONUSCO/Abel Kavanagh.

Focus on sanitation and clean water may improve control of endemic cholera

Pathogens that persist in hosts and environments may require tailored management strategies, according to new study of endemic cholera interventions in Sub-Saharan Africa.

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.

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.

The findings could help drive future research as well as help evaluate the costs and benefits of pesticide use in agroecosystems, the researchers said. Credit: Kym MacKinnon/Unsplash. All Rights Reserved.

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.
