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.
Watching bacteria and viruses duke it out, evolving to outwit each other.

A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.

Antisense therapy showed promising results in a first-in-human trial for Huntington's disease.
As genes are favored or phased out, human evolution continues.
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.
Some animals seem to have missing genes – but the reality is a lot more intriguing.
Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.

Two US researchers have traced the majority of cancers to DNA replication errors during our natural cell replacement. Their finding asks for a renewed inquiry into the role of "chance" in cancer.
What can a single person’s flu infection tell you about how the virus changes around the world?
Xue and Bloom
New genetic technologies are letting us look at flu evolution right where it starts: within individual people, while they're sick.
Listening to audio derived from DNA may help scientists better understand how cell biology works.
Converting a DNA sequence into an audio could help us learn something useful about it, like where mutations occur.
Laboratory mice are among the first animals to have their diseases treated by CRISPR.

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.
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
There are genetic difference within and between tumors.

Not only are tumors are different from one another, but there can even be genetic differences within a single tumor.

A gene mutation that causes problems for neural stem cells – the building blocks of the brain – could be corrected by adding carnitine.
It’s naive to pretend there are no profound genetic and epigenetic differences between the sexes.

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?
Genetic therapy might be able to reverse the harmful effects of sickle cell anaemia.
Gene therapy is allowing us to switch on natural beneficial mutations to counteract the effects of negative mutations in diseases such as sickle cell anaemia.
