Genes Behind Dog Behaviors Also Shape Human Emotions
Summary: 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…
Genetics Point to a New Type of Suicide Risk
Summary: 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 Roots of Depression Reveal Strong Suicide Risk Signals
Summary: 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…
AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health
Summary: 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…
$2 Saliva Test Could Help Detect Depression and Schizophrenia
Summary: Scientists have developed a portable biosensor that can detect levels of BDNF, a protein linked to mental health conditions such as depression, schizophrenia, and bipolar disorder. The flexible, low-cost…
Child Abuse Leaves Lasting Biological Scars on the Brain and DNA
Summary: New research reveals that child maltreatment leaves measurable biological “scars” on DNA, altering brain structure and function. Using a genome-wide epigenetic analysis, scientists identified four key methylation sites—ATE1, SERPINB9P1,…
Genes Linked to Cannabis Use Reveal Ties to Mental Health
Summary: Researchers analyzing data from over 130,000 participants have identified specific genes associated with cannabis use and its frequency, revealing strong links to psychiatric, cognitive, and physical health traits. The…
1 gene, 1 disease no more – acknowledging the full complexity of genetics could improve and personalize medicine
Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide…
Dietary RNA Molecules May Hold the Key to Slowing Cellular Aging
Summary: Living longer doesn’t always mean living healthier, and researchers are exploring how diet can extend healthspan. A study in worms shows that specific dietary RNA molecules protect cells from…
