Placenta assessment tool aims to improve neonatal, maternal care

A multi-national, multi-institutional team led by Penn State researchers developed a new tool that enables doctors to examine placentas right at the bedside using just a phone.

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

Center for Socially Responsible AI awards seed funding to seven diverse projects

The Penn State Center for Socially Responsible Artificial Intelligence (CSRAI) has announced the results of its most recent seed-funding competition.

Penn State and U.S. National Science Foundation representatives cut a ribbon celebrating the official launch of the U.S. National Science Foundation National Synthesis Center for Emergence in the Molecular and Cellular Sciences (NCEMS) with the Penn State Nittany Lion mascot. The NCEMS launch took place on Monday, Nov. 18, and provided information about open calls for working groups, fellowships and internships, as well as a growth trajectory over the next five years.

Q&A: How do microbiomes influence the study of life?

Microorganisms — bacteria, viruses and other tiny life forms — may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstein, director of Penn State’s One Health Microbiome Center within the Huck Institutes of the Life Sciences.

The novel Cleavage High-throughput Assay (CHiTA) developed at Penn State provides a scarless method to characterize thousands of diverse small self-cleaving RNA enzymes, called twister ribozymes, in a single experiment. The image shows 2D models of some of the tested ribozymes that had imperfections in their helical and loop elements but were still active, demonstrating that twister ribozyme's ability to self-cleave is tolerant of these slight structural imperfections.
