Flatheads grow fast in this river system, attain large body sizes and can eat a variety of prey. Because adult flatheads have few natural predators, they can exert strong control over the ecosystem. Credit: Penn State. Creative Commons

Invasive flathead catfish now top predators in Susquehanna River in Pennsylvania

New study suggests that smallmouth bass and channel catfish are changing what they eat to avoid having to compete with or being eaten by the invader.

A team at Penn State has developed a novel wearable sensor capable of continuously monitoring low rates of perspiration for the presence of a lactate — a molecule the body uses to break down sugars for energy. Credit: Provided by Farnaz Lorestani. All Rights Reserved.

Don’t sweat it: New device detects sweat biomarker at minimal perspiration rate

Non-invasive, wearable sensor can identify and track lactate in low-perspiration conditions, researchers say.

Connection among gut fungi, genetics and disease risk in humans identified

Novel genome-wide association study sheds light on the human genetic determinants of the fungal component of the human microbiome and their relation to chronic disease.

Huck launches new seed grant program to support research in MRI Core Facility

Penn State’s Huck Institutes of the Life Sciences is requesting proposals for a new “Life at All Scales” seed grant program that will afford researchers opportunities to explore the capabilities of the High-Field Magnetic Resonance Imaging (MRI) Core Facility. Proposals are due Sept. 30.

Penn State petition calls for support of federally funded research

A petition launched by Penn State invites the University community to support continued federal investment in research that plays a vital role in life-changing solutions, powering economic growth across the commonwealth and beyond, and driving transformational discovery.

New research by Penn State scientists shows that migration of farming groups was the dominant factor in the spread of agriculture, while cultural adoption by hunter-gatherers only played a minimal role.

Ancient DNA reveals farming spread through migration, locals slow to adopt it

Using mathematical models, computer simulations, and ancient DNA analysis, an interdisciplinary team of scientists at Penn State was able to measure how migration and cultural adoption each contributed to the expansion of farming.

Research sheds light on Beech Creek’s struggle with abandoned mine drainage

Students in the TREES dual-title graduate degree program partnered with residents to gather data and build support for watershed restoration.

Zinc enrichment and light intensity affect the nutritional composition of radish microgreens, shown here. The researchers found that high light intensity decreased the production of plant-defense compounds while it increased the production of antioxidants. Credit: Penn State. Creative Commons

Fine-tuning zinc supplementation, light exposure to boost microgreens’ nutrition

Microgreens, which are young, edible plants that only take one to three weeks to harvest, are more than garnish at trendy restaurants — they could be the answer to global hunger, according to plant scientists at Penn State.
