Researchers analyze 2.2 million genomes to show that addiction risk is primarily driven by broad genes affecting brain wiring and impulse control, not drug-specific traits.

Chimpanzees are adapted to live across diverse habitats in Africa, but little is known about the potential adaptation of chimps in different environments. A new study has found that these apes possess ...

UC Davis Ph.D. candidate Abigail Morris is studying how environmental factors influence the decisions individual monkeys make when they disperse from their family groups in the Amazon. (Courtesy photo ...

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 ...

A new study has developed a powerful computational method that can detect how genes interact with each other to influence complex traits in humans at a scale previously impossible. The new method was ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

It's no secret that smoking is extremely detrimental to health. Tobacco smoke contains thousands of chemicals, including carcinogens, increasing the risk of cancer, cardiovascular and respiratory ...

SEATTLE — Up to 10% of cancers are hereditary, which means they can be passed from generation to generation through genetic mutations. Genetic counseling can help you figure out if a cancer in your ...

Your genes can increase the risk of depression, especially if you have a close relative with it. Depression is not caused by a single gene, but by variations in many genes. Twin studies show that ...

Imagine if scientists could reach back through time and recover the genetic blueprints of species that vanished thousands of years ago, then use those ancient instructions to rebuild lost traits in ...

Most people notice it gradually. A little more hair on the pillow. A slightly wider part. A hairline that seems to be slowly ...
