A lack of diversity in genetic databases is making precision medicine ineffective for many people. One historian proposes a solution: construct reference genomes for individual populations.
Mammoths evolved to handle the cold over hundreds of thousands of years and North America may been home to a hybrid species, a new study finds.
In a Yucatan nature park, engineered genes influence nectar production, affecting ants’ and maybe pollinators’ attraction to the wild cotton plants.
Having two mitochondrial genetic instruction books, a first for vertebrates, may help explain tuatara’s unique ability to tolerate cold temperatures.
Mutations arising early in development may account for genetic differences between identical twins.
DNA suggests that the deadly bacterium that causes the plague reached northeast Asia by 4,400 years ago.
A gene that ticks acquired from bacteria 40 million years ago may help the arachnids keep potential pathogens at bay while feeding on blood.
A new study challenges a long-held belief that essential genes change little over time.
Researchers have located a shared hot spot — on the HLA-B gene — in the immune system in people who say they have penicillin allergies.
By turning genes on or off, the parasite keeps blood levels low but persistent, so infection doesn’t set off alarm bells for the immune system.
