A 30-year study by University of California, Riverside researchers has challenged a central idea of evolutionary biology by finding that mice bred for extraordinary athletic ability paid no biological price in lifespan or reproductive success, according to findings published in Behavior Genetics. The Three-Decade Mouse Experiment That Defied Evolutionary Theory According to research led by … Read more
Aging brain biology actively shapes brain tumor progression, treatment resistance, and cognitive decline, according to a review published in Ageing and Cancer Research & Treatment. Rather than viewing aging as a passive background variable, the study—titled “Navigating the aging brain: The interplay between brain malignancy and the aging microenvironment”—proposes that the physiological shifts of an … Read more
Lifestyle factors like an unhealthy diet can worsen the effects of genetic causes of male infertility, according to a proof-of-concept study published in Human Reproduction. Led by Dr Jessica Dunleavy and Professor Moira O’Bryan from the University of Melbourne’s School of BioSciences, the research used a mouse model carrying defects in the M1AP gene to … Read more
Mapping human brain function requires tracking single-cell and spatial multi-omics across molecular layers, according to a review published in EXO – Beyond the Cell. Traditional bulk tissue measurements often miss the complex anatomical and microenvironmental niches that define neurological diseases like Alzheimer’s and Parkinson’s. Single-Cell Multi-Omics and Disease Progression Understanding molecular changes in the brain … Read more
Researchers at the University of California Riverside found that nanomolar concentrations of vanillin cause stem cells to lose pluripotency and prematurely differentiate into endoderm tissue, a mechanism that may help explain clinical links between vaping, difficulty conceiving, and miscarriages. How Vanillin Targets Embryonic Stem Cells Laboratory tests conducted on human embryonic stem cells—which are similar … Read more
According to a study published on August 7, 2026, in Volume 17 of Oncotarget, treatment with the multi-kinase inhibitor K252a transiently delayed the growth of SK-ES-1 Ewing sarcoma tumor xenografts in immunodeficient mice. Led by researchers at the Federal University of Rio Grande do Sul and INCT BioOncoPed in Brazil, the team found that the … Read more
Recent research reveals that arthropod fertilization often relies on sperm cooperation rather than individual competition, reshaping evolutionary biology understandings of reproduction. According to a study published in Nature Communications by evolutionary biologists from Syracuse University, the University of Siena, and the University of Szeged, sperm cells in numerous species form coordinated groups using sperm-associated material … Read more
Endometriosis, a reproductive condition affecting roughly 1 in 10 women worldwide, can now be detected through a non-invasive saliva test called Endotest, following approval from the National Institute for Health and Care Excellence (NICE) in the UK. According to Yale Medicine, women face an average wait of 11 years between their first symptoms and a … Read more
Senescent cells—damaged cells that stop dividing but remain metabolically active—accumulate lipid droplets as a hallmark of their aging state, according to a study published July 1, 2026, in the journal Aging. Researchers led by Noa Rachmian-Cooper and Valery Krizhanovsky at the Weizmann Institute of Science found that these lipid deposits are linked to chronic inflammation … Read more
Modern IVF treatments now achieve a 68.2% cumulative live birth rate over three cycles while maintaining a multiple birth rate of just 2.9%, according to research presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE). This represents a significant improvement over historical methods that often resulted in multiple … Read more
