Plant-Based Diet Could Turn Back Biological Aging

A new study suggests that eating more plant-based foods rich in natural compounds called methyl adaptogens—like turmeric, berries, garlic, and green tea—may slow the body’s biological aging process. Researchers analyzed DNA methylation, a cellular marker of aging, in men aged 50 to 72 who followed a nutrient-rich, plant-forward lifestyle.

Parents’ Age, Ancestry, and Habits Shape New DNA Mutations

A massive genomic study has revealed that parental age, ancestry, and smoking habits subtly influence the number of new genetic mutations (de novo mutations) passed from parents to children. By analyzing whole-genome data from 10,000 parent-child trios, researchers found that most variation in mutation rates comes from parental age, especially the father’s.

Prenatal Stress Leaves Lasting Molecular Imprints on Babies

A new study reveals that stress during pregnancy can molecularly reprogram newborns' stress response systems, with significant differences between boys and girls. Researchers found that maternal stress altered entire families of tRNA fragments in umbilical cord blood, particularly those regulating acetylcholine, a key neurotransmitter.

Maternal Childhood Trauma Linked to Rapid Weight Gain in Baby Boys

A new study reveals that maternal childhood trauma—such as neglect or abuse—can trigger rapid weight gain in male infants as early as the first two months of life. Researchers found that boys born to mothers who experienced early-life adversity gained significantly more weight per day than average, despite being full-term, healthy, and mostly breastfed.

Brain Enzyme Limits Risk of Drug Relapse

New research reveals that the enzyme HDAC5 plays a critical role in suppressing a gene (Scn4b) that regulates brain activity associated with drug-related memories, which are central to relapse in substance use disorders (SUDs). By limiting expression of Scn4b, HDAC5 reduces the excitability of neurons in the brain’s reward system, weakening the formation of powerful drug-environment associations.

Schizophrenia Risk May Begin in the Placenta

A new study highlights the placenta’s role in neuropsychiatric development, showing that DNA methylation influences gene expression tied to psychiatric disorders. Researchers found strong links between placental DNA methylation and conditions like schizophrenia, bipolar disorder, and major depression.

Mutations Drive Aging and Shape Epigenetic Clock

A new study has uncovered a direct link between somatic mutations and epigenetic modifications, challenging established views on aging. Researchers found that random genetic mutations drive predictable changes in DNA methylation, offering new insights into the relationship between mutation accumulation and epigenetic clocks.

Early Stress Alters Sperm DNA, Impacting Offspring’s Brain Development

Childhood stress may leave lasting marks on sperm, altering epigenetic profiles and potentially influencing brain development in offspring. Researchers found that men with high levels of childhood maltreatment had changes in DNA methylation and non-coding RNA levels in their sperm.

Leaded Gas Exposure Linked to Mental Illness

A new study estimates that childhood lead exposure, peaking between 1960 and 1990 due to leaded gasoline, caused 151 million excess cases of mental illness by 2015. Researchers linked historic lead exposure data to mental health symptoms, finding that personality changes and mental health disorders were most pronounced among Generation X.

Maternal Inflammation May Shape Offspring’s Alzheimer’s Risk

Maternal immune activity during pregnancy influences memory circuitry in offspring, with sex-specific effects extending into midlife. Elevated immune markers like IL-6 and TNF-a in mothers were linked to adverse brain activity in memory regions, particularly in postmenopausal women, and lower cognitive performance in children.

Cannabis Use Linked to Epigenetic Changes, Cancer Risk

Research indicates that cannabis use causes cellular damage that increases the risk of highly cancerous tumors by disrupting mitochondria and damaging DNA. This genotoxicity can result in mutations, accelerated aging, and birth defects, with potential to be passed on to future generations through egg and sperm. Insights from broader mitochondrial research provide a mechanistic understanding of how cannabis affects genetic stability.
