Genes Behind Dog Behaviors Also Shape Human Emotions

Researchers analyzed the genomes and behavioral profiles of 1,300 golden retrievers and found that several behavioral traits—such as trainability, fear of strangers, and aggression toward other dogs—are shaped by specific genetic variants. Remarkably, a dozen of these same genes also influence emotional and cognitive traits in humans, revealing shared biological roots across species.

Gene Discovery Reveals Hidden Risk Pathway for Delirium

A massive genetic analysis of over one million people has revealed that APOE, long known for its role in Alzheimer’s disease, also independently increases a person’s risk of delirium. The researchers found that this effect cannot be explained solely by dementia, showing that APOE directly contributes to delirium vulnerability in otherwise cognitively healthy individuals.

Genetics Point to a New Type of Suicide Risk

New research shows that many people who die by suicide without prior suicidal thoughts or behaviors are not simply “missed cases”—they may have an entirely different underlying risk profile. Genetic analyses of more than 2,700 deaths revealed that these individuals carry fewer genetic risk factors for major psychiatric conditions compared to those with known suicidality.

Genetics Plus Heart Health Markers Sharpen Dementia Risk

New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.

Night-Vision Disorders Share a Surprising Cellular Trigger

New research reveals that the loss of a single ion channel, TRPM1, is enough to produce persistent rhythmic oscillations in the retina, a feature observed in both congenital stationary night blindness and retinitis pigmentosa. By comparing Trpm1 and mGluR6 knockout mice, researchers identified a disrupted circuit between rod bipolar cells and AII amacrine cells that produces anti-phase oscillations interfering with visual signaling.

Genetic Roots of Depression Reveal Strong Suicide Risk Signals

New research shows that depression beginning before age 25 has a much stronger hereditary component than depression that emerges later in life. By analyzing genetic data from over 150,000 people with depression, researchers identified distinct genetic regions linked specifically to early-onset cases.

Genome Study Reveals True Genetic Influence on Traits

Using full genome sequencing data from more than 347,000 individuals, researchers quantified how much genetic differences explain human traits such as height, body mass index, fertility, and disease risk. The results show that genes account for roughly 30% of the variation between individuals, with higher estimates for traits like height and lower for fertility.

Autism and ADHD Brain Patterns Reveal Shared Biological Roots

A new study shows that autism symptom severity, rather than a formal diagnosis, aligns with shared brain-connectivity patterns across children diagnosed with autism or ADHD. Stronger autistic traits were linked to heightened connectivity between frontoparietal and default-mode networks, regions central to social cognition and executive functions.

3D Brain Map Reveals How Inflammation Reawakens Developmental Genes

Researchers have developed the most detailed molecular map yet of how the brain develops and reacts to inflammation, revealing that disease processes can “reawaken” genes from early life. Using a new spatial tri-omics technique, the team tracked how gene activity, epigenetic changes, and protein production interact in specific brain regions.

AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health

For the first time, scientists have mapped the genetic architecture of the brain’s communication bridge—the corpus callosum—using AI and MRI data from over 50,000 people. The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.

BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Antioxidant Defense System in the Brain Discovered

A new study identifies biliverdin reductase A (BVRA) as a crucial enzyme defending neurons from oxidative stress, acting independently of its traditional role in bilirubin production. Using genetically modified mice, researchers found that BVRA binds directly to NRF2, a master regulator of antioxidant defense, ensuring the activation of protective genes that maintain cellular health.
