Cancer

Are all cancer cells the same?

Take two cancer cells and compare their genomes. Surprisingly, they can be quite different. This genetic variation is one of the hallmarks of cancer, and one reason why treating cancer is so hard.

Tiny worm mimics key genetic risk for Alzheimer's

Researchers at The University of Alabama have shown a tiny worm can replicate genetic causes of Alzheimer's disease, expanding the breadth of preclinical models for the disease.

A shared past for East Africa's hunter-gatherers

Languages that involve "clicks" are relatively rare worldwide but are spoken by several groups in Africa. The Khoisan language family includes a handful of these click languages, spoken by hunter-gatherer groups in southern ...

Researchers find genetic vulnerability to menthol cigarette use

A genetic variant found only in people of African descent significantly increases a smoker's preference for cigarettes containing menthol, a flavor additive. The variant of the MRGPRX4 gene is five to eight times more frequent ...

Genetic variation

Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the “raw material” for natural selection.
