Clinicians' ability to diagnose and treat chronic diseases is limited by scientific uncertainty around factors contributing to disease risk. A study published September 2 nd in the open-access journal ...

The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

Animal breeding has traditionally focused on improving mean trait performance; however, contemporary research increasingly highlights the significance of genetic variation not only in trait means but ...

By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than ...

Evolutionary biologists study the changes that occur in plants, animals, and microbes over time and within current populations. When addressing a virus outbreak (like COVID-19), scientists in this ...

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 ...

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 ...

Skin aging is a multifaceted biological phenomenon influenced by an array of factors, including genetic, hormonal, metabolic, and environmental contributors. The aging process of the skin varies ...

A new study from the NIH’s All of Us program is shaking up long-held assumptions by revealing that genetic ancestry rarely aligns with racial labels — and that the interplay between biology and ...

Even a single gene, reshuffled or regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a recent study of wheatear birds. A study was recently published in the ...
