Novel biogel may solve a hairy problem for wearable brain-monitoring systems

A vital tool for healthcare practitioners, electroencephalography (EEG) systems measure electrical activity in the brain through electrodes placed on the scalp, but getting reliable readings can be surprisingly difficult. Hair interferes with contact between the electrodes and skin, and the gels used to improve those connections often dry out over time, weakening signal quality. Researchers at Penn State have developed a reusable material designed to solve both problems at once. The material is a thermoreversible semiconducting ionic biogel, meaning it becomes liquid when gently heated so it can move through hair and reach the scalp, then returns to a stable gel as it cools, keeping its conducting and semiconducting character.

New Beescape updates include county-level plant recommendations for pollinators

Penn State’s Beescape tool is gaining a new feature that allows users to download county-specific lists of pollinator-attractive plants, offering a more localized approach to improving pollinator habitats across Pennsylvania. The feature, developed by a multidisciplinary team of researchers at Penn State’s Center for Pollinator Research in the College of Agricultural Sciences, allows users to generate lists of plants tailored to ecological conditions at the county level.

$3M NIH grant to support research on memory and exaggerated fear responses

Experiencing a traumatic event sometimes produces long-lasting biological changes that can lead to an exaggerated fear response to future stressful events, such as what occurs in individuals with post-traumatic stress disorder. To better understand the regulatory mechanisms in the brain that produce this biological memory and exaggerated fear response, a team of researchers from Penn State and the University of Wisconsin-Milwaukee has been awarded a grant from the U.S. National Institutes of Health’s National Institute of Mental Health.

Worker bumble bees help determine which baby bee will become queen

Every bumble bee colony has a queen, but a new study led by researchers at Penn State suggests the process of determining which baby bee reigns supreme may be less monarchal than the royal title suggests. The study explored why some bumble bee larvae become workers and others become queens, despite coming from the same eggs.

Stretchy implants could stick to arteries to treat high blood pressure

High blood pressure, formally known as hypertension, is a leading cause of heart disease in the United States, impacting nearly half of all adults. Approximately one in 10 of these patients experience drug-resistant hypertension that can be difficult to address, but according to researchers at Penn State, tiny devices that gently shock one of the body's most critical arteries could offer effective treatment.

Q&A: What can plant evolution teach people about breeding better crops?

May 22 is United Nations International Day for Biological Diversity, drawing attention to a critical resource for developing crops that are resilient or resistant to extreme weather and other threats to their health, according to Jesse Lasky, associate professor of biology at Penn State.

College of Ag Sciences, FAO mark one-year anniversary of Youth Food Lab

Penn State’s College of Agricultural Sciences welcomed a delegation from the Food and Agriculture Organization of the United Nations, or FAO, to University Park last week to mark the first anniversary of the World Food Forum Youth Food Lab North America at Penn State partnership and to explore opportunities to deepen collaboration on global agrifood systems, innovation and education.

Q&A: Is AI democratizing global health or reinforcing old inequities?

Artificial intelligence is rapidly transforming the tools that are central to global health decision-making in areas like disease control policies, financing and vaccination strategies, such as infectious disease modeling. This brings new opportunities to the modeling landscape, but could also exacerbate existing disparities, according to Matt Ferrari, professor of biology and director of the Center for Infectious Disease Dynamics at the Huck Institutes of Life Sciences at Penn State.

Q&A: Tips to protect against ticks

May is Lyme Disease Awareness Month, and Pennsylvania consistently ranks as one of the top states in the nation for reported cases of Lyme disease and other tick-borne illnesses. However, there are ways to protect people, pets and livestock against ticks and the pathogens they carry, according to Erika Machtinger, associate professor of entomology in Penn State’s College of Agricultural Sciences.

Elevated blood sugar levels during pregnancy may result in poorer birth outcomes

Pregnant women in the United States are routinely tested for gestational diabetes, a condition where the body has high blood sugar during pregnancy that can lead to health problems for both mothers and babies. In a recent study led by Penn State researchers, scientists examined records from thousands of births and found that failing the glucose challenge test was associated with babies with higher birth weights — a risk factor for future obesity and diabetes — even when women passed their second glucose test.
