Huck Grad Students Hold Virtual Life Sciences Symposium

Huck Graduate Students organized a virtual Life Sciences Symposium, welcoming keynote speakers from Penn State and internationally, and giving awards for outstanding student presentations.

Coupled brain activity, cerebrospinal fluid flow could indicate Alzheimer's risk

Penn State researchers may have discovered a potential marker to clinically evaluate patients’ risk for Alzheimer’s disease through non-invasive imaging tests, according to a study published in PLOS Biology. The finding may have implications for diagnosis and treatment of the disease that results in significant cognitive decline, the researchers said.

New images of canine parvovirus may help predict how virus jumps to new species

​Canine parvovirus (CPV) is a highly infectious pathogen that causes severe diseases in unvaccinated dogs, including inflammation of the heart and acute gastrointestinal illness. Originating in cats, the virus is a rare example of a DNA-based virus that can jump between species, and a team of researchers’ discovery may help in predicting this and the virus’ ability to evolve, which could have implications for current vaccines used in dogs.

Reef-building corals and microscopic algae within their cells evolve together

The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another’s needs. A new study by Penn State biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals.

Data 4 Action enriches student experience while documenting pandemic

​The Data 4 Action (D4A) project is comprised of dozens of Penn State researchers who are documenting the impacts of COVID-19 in Centre County. While the goal of the project is to assess the biological, psychological and social functioning of Penn State students and community members, the project is also providing new and impactful opportunities for a growing group of students working as research assistants.

Widespread coral-algae symbioses endured historical climate changes

One of the most important and widespread reef-building corals, known as cauliflower coral, exhibits strong partnerships with certain species of symbiotic algae, and these relationships have persisted through periods of intense climate fluctuations over the last 1.5 million years, according to a new study led by researchers at Penn State.

Sufficient knowledge but sense of information overload evident early in pandemic

Residents of central Pennsylvania had the information they needed to slow the spread of COVID-19 early on in the pandemic, but were overwhelmed with worries about mixed messages and distrust of some sources, according to Penn State College of Medicine researchers.

Photo Gallery: A New Home for Ancient DNA

Penn State, the College of the Liberal Arts, and the Department of Anthropology are going online with the new Penn State Ancient Biomolecules Research Environment, or PSABRE. The new facility is one of the largest ancient DNA laboratories in the United States and will host a variety of University and international research teams.

Maternal stress during pregnancy may shorten lifespans of male lizard offspring

Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study.

What makes plant cell walls both strong and extensible?

A plant cell wall’s unique ability to expand without weakening or breaking — a quality required for plant growth — is due to the movement of its cellulose skeleton, according to new research that models the cell wall.
