How cancer cells can become immortal – research finds a mutated gene that helps melanoma defeat the normal limits on repeated replication

One enzyme plays a key role in how tumor cells replicate and divide indefinitely. Identifying the genes that give these cells their immortality could provide new drug targets to treat cancer.

Evolutionary geneticists spot natural selection happening now in people

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.

CRISPR controversy raises questions about gene-editing technique

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.

Differences between men and women are more than the sum of their genes

What produces the differences between men and women? Are they trivial or profound? Are they genetic or environmental, or both? And are men really closer genetically to chimpanzees than to women?
