Neurons sequester the cholesterol-inhibiting TFEB in oligodendrocyte cytoplasm to safeguard myelination and neural function.

Cell Rep

September 2025

Department of Molecular Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA; Peter O'Donnell Jr. Brain Institute, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA; Hamon Center for Regenerative Science and Medicine, University of Texas Southwestern M

Myelination is essential for normal brain function, yet the mechanisms governing neuron-oligodendrocyte interactions that ensure proper myelination levels remain poorly understood. Here, we identify transcription factor EB (TFEB) as a molecular link that connects extrinsic neuronal cues to intrinsic oligodendrocyte transcriptional programs, regulating central nervous system myelination. Using a TFEB epitope-tagged knock-in mouse model, we find that neurons sequester most of the TFEB protein in the cytoplasm of myelinating oligodendrocytes.

With the continued upsurge of antibiotic resistance and reduced susceptibility to almost all frontline antibiotics, there is a pressing need for the development of new, effective, and safe alternatives. In this study, a scaffold-hopping strategy was utilized to develop a novel class of penicillin-binding protein 2a (PBP2a) inhibitors, centered around a 4H-chromen-4-one core structure. These newly designed compounds demonstrated strong antibacterial efficacy against methicillin-resistant Staphylococcus aureus (MRSA) and other drug-resistant gram-positive pathogens.

While cognitive function remains stable for majority of the lifespan, many functions sharply decline in later life. Women have higher rates of neurodegenerative diseases that involve memory loss, including Alzheimer's disease. This sex disparity may be due to longer life expectancies when compared to men; women outlive men by roughly 5 years globally.

Thermodynamics-inspired high-entropy oxide synthesis.

Nat Commun

September 2025

Department of Materials Science and Engineering, The Pennsylvania State University, University Park, PA, USA.

High-entropy oxide (HEO) thermodynamics transcend temperature-centric approaches, spanning a multidimensional landscape where oxygen chemical potential plays a decisive role. Here, we experimentally demonstrate how controlling the oxygen chemical potential coerces multivalent cations into divalent states in rock salt HEOs. We construct a preferred valence phase diagram based on thermodynamic stability and equilibrium analysis, alongside a high throughput enthalpic stability map derived from atomistic calculations leveraging machine learning interatomic potentials.

The Bat Signal: An Ultraviolet Light Lure to Increase Acoustic Detection of Bats.

Animals (Basel)

August 2025

Virginia Cooperative Fish and Wildlife Research Unit, U.S. Geological Survey, Blacksburg, VA 24061, USA.

Bats are a taxa of high conservation concern and are facing numerous threats including widespread mortality due to White-Nose Syndrome (WNS) in North America. With this decline comes increasing difficulty in monitoring imperiled bat species due to lower detection probabilities of both mist-netting and acoustic surveys. Lure technology shows promise to increase detection while decreasing sampling effort; however, to date research has primarily focused on increasing physical captures during mist-net surveys using sound lures.
