Genetic engineering is moving from the lab bench into clinics, farms, and even family planning decisions, promising to change how we prevent disease, age, and define human potential. The same tools ...

Millions thrive at high altitudes due to remarkable genetic adaptations. Tibetans, for instance, possess a gene variant allowing efficient oxygen use without dangerously thick blood. Andeans and ...

Gregor Mendel described his experiments with pea plants and proved that genes are transmitted in discrete units, with certain ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
