Researchers still do not have a comprehensive picture of the factors that influence gene expression in human cancers. Understanding gene expression in cancer is important because it can reveal how the ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

An understanding of the origin and dynamics of heritable genetic variation within classical animal breeding programs is needed to provide the context for understanding the contributions and concerns ...

Genetic inheritance may sound straightforward: One gene causes one trait or a specific illness. When doctors use genetics, it’s usually to try to identify a disease-causing gene to help guide ...

Earth's biodiversity is in crisis. An imminent "sixth mass extinction" threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity—or variation—within species ...

A rapid koala rebound in southeastern Australia is also boosting their genetic variation, showing one way out of an extinction death spiral. After nearly disappearing from the region over a century ...

Scientists have cracked open some of the most mysterious corners of our DNA, revealing that parts of the human genome mutate at a far faster pace than previously imagined. By studying four generations ...
