Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

Yale Cancer Center offers team-based care for breast cancer patients

Hilary Axtmayer can pinpoint the moment her life changed. In 2023, Axtmayer-then a 40-year-old mother of two from Madison, Conn.-was receiving her regularly scheduled breast exam when her gynecologist paused mid-palpation. She'd found a lump.

New method reveals how individual glioblastoma cells spread through the brain

By combining live imaging of brain tissue with artificial intelligence, researchers at Uppsala University have developed a method that reveals how individual glioblastoma cells spread through the brain, how they can switch between different ways of moving, and how they are affected by cancer treatments. An

$32 million grant extends landmark Alzheimer's research through 2031

When Leonard Berg, MD, then a neurologist at Washington University School of Medicine in St. Louis, noticed memory problems among his older patients in the 1970s, he refused to dismiss the problems as part of "normal aging" or senility but instead set out to understand what was happening in their brains.

Hidden genetic differences in gut bacteria may hold clues to aging

Researchers analyzed approximately 12.8 million gut microbial genetic variants in 10,781 individuals across six cohorts, identifying 940 independent associations with 69 human health characteristics and environmental exposures. Nearly two-thirds of these associations were not accompanied by significant differences in bacterial species abundance, suggesting that microbial genetics can reveal relationships overlooked by conventional microbiome analyses, although causality remains unproven.

Tau spreads more rapidly in early-onset Alzheimer's disease

Patients with early-onset Alzheimer's disease, whose symptoms start before age 65, have more extensive deposits of tau, a hallmark protein of the condition, compared with patients whose symptoms start at 65-plus, a new study found.

Brain scans reveal clues to Alzheimer's risk years before memory loss begins

Inside the brains of some cognitively normal adults, firing patterns were able to foretell Alzheimer's disease years before the onset of memory loss or the accumulation of plaques and tangles, according to new Stanford Medicine-led research.

Workplace exposure to petroleum-based lubricants linked to higher MS risk

Exposure to petroleum-derived lubricants at work, including engine oil, hydraulic oil and cutting fluids used to cool or lubricate metal during metalworking, is associated with higher odds of multiple sclerosis (MS), according to a study published November 4, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Modern lifestyles may be changing our gut bacteria in unexpected ways

A global study of 1,015 adults across 12 countries found that industrialized lifestyles were associated with lower gut bacterial diversity, reduced microbial community stability, and increased markers of intestinal stress and immune activity. The researchers also found that a microbiome-based health index developed using industrialized populations performed poorly in less-industrialized communities, raising concerns about its applicability across diverse populations.
