Articles about 'genetics'

Modern humans descended from not one, but at least 2 ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.

Researchers at the University of Cambridge have discovered genes linked to obesity in both Labradors and humans. They say the effects can be over-ridden with a strict diet and exercise regime.

In 1994, a landmark paper identified a gene – BRCA1 – that significantly increases the risk of breast and ovarian cancers when faulty. Thirty years on, we look at the major impact it has had on how we understand and treat cancer – and why there is still much to learn.

Dr Alex Cagan – illustrator, geneticist and explorer of animal DNA – is offering a new perspective on the tapestry of life. His work has profound implications for the pursuit of healthy ageing and the possibilities of cancer resistance.

Cambridge scientists have identified the genetic mutation that causes progressive retinal atrophy in English Shepherd Dogs, which results in incurable blindness, and developed a genetic test to help eliminate the disease from future generations of the breed.

Cambridge researchers have identified genetic variants in two genes that have some of the largest impacts on obesity risk discovered to date.

The largest ever study of the genetics of the brain – encompassing some 36,000 brain scans – has identified more than 4,000 genetic variants linked to brain structure. The results of the study, led by researchers at the University of Cambridge, are published in Nature Genetics.

A large-scale international collaboration has identified new genes associated with breast cancer that could eventually be included in tests to identify women at increased risk of the disease.

An international team of researchers has found a genetic variant that may explain why some people of African ancestry have naturally lower viral loads of HIV, reducing their risk of transmitting the virus and slowing progress of their own illness.

Cambridge researchers are helping launch a nationwide study for children and young people to unlock the power of our DNA.
