Researchers recognized for excellence by Institute of Energy and the Environment

The Institute of Energy and the Environment recognized six Penn State faculty members for their research excellence.

The Penn State Neuroscience community kicked off their 2024-25 seminar series with presentations by the second-year doctoral students in the Huck Neuroscience Program. The 2024 Big 10 Neuroscience Annual Meeting will provide similar events for student presentations and networking and will feature presentations from all career stages.

Fourth annual Big Ten Neuroscience Symposium to convene at Penn State

The Penn State Neuroscience Institute, through the Huck Institutes of the Life Sciences and the Penn State College of Medicine, will host the Big Ten Neuroscience Annual Meeting on July 21 and 22 at the Nittany Lion Inn in State College.

New research finds sex-specific regions of the brain can relieve the detrimental effects of chronic stress in male and female mice. Left: Schematic showing a cortical microcircuit with three types of interneurons expressing somatostatin (SST), parvalbumin (PV) or vasointestinal peptide (VIP) and their distinct patterns of innervation of glutamatergic output neurons (PNs), with thin lines representing axons that send chemical signals and the thicker lines of PNs representing dendrites that receive information. There is selective innervation of the distal ends of PN dendrites by axons of SST neurons. Right: Increased activity of SST neurons by genetically induced disinhibition, on top right, or by chemogenetic activation of SST neurons in the medial prefrontal cortex, on bottom right, leads to stress resilience and facilitates the reversal of the detrimental behavioral effects of stress exposure in male but not female mice.

Brain regions that relieve effects of chronic stress in mice differ based on sex

In two new studies, researchers made mice resilient to stress by activating neurons in different brain regions and found that the changes involved are highly sex-specific

Relieving chronic stress in the brains of male and female mice

In two new studies, researchers made mice resilient to stress by activating neurons in different brain regions and show that the brain regions and gene expression changes involved are highly sex-specific.

Three Penn State researchers awarded scientific grants from Kaufman Foundation

The Charles E. Kaufman Foundation — a supporting organization of The Pittsburgh Foundation, which works to improve the quality of life in the Pittsburgh region — has selected three Penn State researchers to receive scientific research grants. The foundation awards grants to scientists at institutes of higher learning in Pennsylvania who are conducting innovative, fundamental scientific research in the fields of biology, chemistry and physics.

New experimental technique developed by Penn State researchers helps uncover how certain proteins cooperate to bind to otherwise closed regions of the genome to facilitate cell differentiation and development. Illustration shows expanded view of chromosome from a cell at the upper left. The “pioneer factor” FOXA1 co-binds with AP-1, allowing FOXA1 to locate target sites in the genome with high specificity.

Genomic pioneers collaborate to access the inaccessible

A new experimental method allows researchers to dissect how certain proteins, called pioneer factors, can bind to selective regions of the genome that are inaccessible to other DNA binding proteins.

Cancer drug could treat early-stage Alzheimer’s disease, study shows

A type of drug developed for treating cancer holds promise as a new treatment for neurodegenerative diseases such as Alzheimer’s, according to a recent study by researchers at Penn State, Stanford University and an international team of collaborators.

Rewriting the evolutionary history of critical components of the nervous system

A new study has rewritten the conventionally understood evolutionary history of certain proteins critical for electrical signaling in the nervous system. The study, led by Penn State researchers, shows that the well-studied family of proteins — potassium ion channels in the Shaker family — were present in microscopic single cell organisms well before the common ancestor of all animals.

Re-engineering cancerous tumors to self-destruct and kill drug-resistant cells

A team led by Penn State researchers has created a modular genetic circuit that turns cancer cells into a “Trojan horse,” causing them to self-destruct and kill nearby drug-resistant cancer cells. Tested in human cell lines and in mice as proof of concept, the circuit outsmarted a wide range of resistance.

Food, not sex, drove the evolution of giraffes’ long neck, new study finds

Why do giraffes have such long necks? A study led by Penn State biologists explores how this trait might have evolved and lends new insight into this iconic question. The reigning hypothesis is that competition among males influenced neck length, but the research team found that female giraffes have proportionally longer necks than males — suggesting that high nutritional needs of females may have driven the evolution of this trait.
