HERV-K10 Retrotransposes in Human Cancer Cells: An Etiology Factor for Glioblastoma Aggressiveness

This study challenges the prevailing view that Human Endogenous Retroviruses (HERV-K) are inactive by demonstrating that the HERV-K10 element actively retrotransposes in human cancer cells and immature oocytes, where this process drives genomic instability and induces aggressive, metastatic cancer stem cell-like characteristics in glioblastoma.

Striatal inflammation is exacerbated by impaired resolution in a model of ASD: environmental enrichment rescues neuroimmune and behavioral deficits

This study demonstrates that in an ASD mouse model carrying the R451C Neuroligin-3 mutation, impaired resolution of striatal inflammation drives synaptic and behavioral deficits through lipidomic and glial dysregulation, which can be fully reversed by environmental enrichment that restores endogenous inflammatory resolution pathways.

A Spatial Risk Model Reveals a 25 μm Transcriptomic Event Horizon for Plaque-Associated Myeloid Activation in Alzheimer’s Disease

By analyzing high-resolution spatial transcriptomics data from Alzheimer's disease brains, this study identifies a precise 25 μm spatial threshold where myeloid cells abruptly transition from a homeostatic to a disease-associated state, revealing specific early-warning biomarkers and regulatory drivers within this critical event horizon.

Signatures of selection underlying adaptation and production performances in tropical Bos indicus cattle: A systematic review

This systematic review synthesizes genome-wide selection-signature evidence from 58 studies to identify a reproducible core of candidate genes in tropical *Bos indicus* cattle that govern both climate adaptation (thermotolerance and immunity) and production traits, providing priority targets for breeding strategies that enhance resilience without compromising productivity.

Genetic variants associated with on-water sports performance: A systematic review

This systematic review of 28 studies identifies 17 genetic variants across eight populations associated with on-water sports performance but concludes that current evidence is insufficient for meta-analysis, highlighting the need for larger, diverse, and collaborative genome-wide studies to fully understand the genetic basis of athletic success in these disciplines.

Systematic screening of brain neurotransmitter enzymes for radical pair mechanism competence reveals quantitative constraints on magnetic field sensitivity

This study computationally screens human brain enzymes for radical pair mechanism (RPM) competence, finding that while eight of nine candidates meet necessary spin-parameter conditions, severe quantitative barriers—specifically prohibitive exchange coupling requirements and short coherence times—effectively rule out RPM-based magnetic field sensitivity in neurotransmitter-metabolizing enzymes, leaving cryptochrome as the sole defensible RPM host.

Hemangio-organoids derived from human pluripotent stem cells support the formation of dendritic cells

This study demonstrates that human pluripotent stem cell-derived hemangio-organoids can be efficiently differentiated via a scalable, non-genetic protocol into functional dendritic cells capable of stimulating T-cell responses, highlighting their potential as a source for immune cell therapies in regenerative medicine.
