Changes in our environment can reveal previously hidden mutations in our DNA with potentially good and bad consequences.
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
Your genes, your saliva and the bacteria that live in your mouth all shape how food tastes and what you prefer to eat.
