Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...
Most of the genetic risk for developing a substance use disorder comes from genes that broadly affect how our brains process ...
Seven years ago, I took a bet from one of the most controversial figures in the scientific world. Charles Murray, the political scientist who—along with the late psychologist Richard Herrnstein—wrote ...
An estimated 170,000 Australians were diagnosed with cancer in 2025. Many people know the causes of cancer are partly genetic. But how do your genes, which contribute so much of what makes you you, ...
Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called ...
Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...
In the 1990s, Lee Sweeney, a physiologist at the University of Pennsylvania, demonstrated that inserting the gene encoding insulin-like growth factor 1 (IGF-1) into the muscle cells of mice increased ...

Common gene variant may raise Alzheimer’s risk; researchers eye gene therapy
A genetic variant carried by at least one-fifth of the population may do far more than raise the odds of developing Alzheimer’s disease. New research argues that inheriting two copies of the APOE4 ...
