Gene study shows human skin tone has varied for 900,000 years

Posted on 12 Oct 2017 in Evolution, Genetics, Journalism

Skin tone has varied greatly among humans for at least the last 900,000 years. So concludes an analysis of the genetic variants associated with skin pigmentation in people from several regions of Africa. The latest findings suggest that some particularly dark skin tones evolved relatively recently from paler genetic variants. Image: llamnudds

The three ancestral tribes that founded Western civilisation

Posted on 1 Jul 2015 in Evolution, Featured, Human Origins, Journalism

Not too long ago, the founding of Europe seemed beguilingly simple. Our species arrived 45,000 years ago from the Middle East, outcompeted the Neanderthals, and that was that. But ancient DNA studies have led to a revolution in European prehistory studies. Image: Effervescing Elephant

Genetic risk of Alzheimer’s has gender bias

Posted on 15 Apr 2014 in Alzheimer's, Journalism

Carrying a copy of the “Alzheimer’s gene” doesn’t significantly raise a man’s risk of developing the disease. The gene does increase a woman’s risk, but women with one copy of the gene were as likely to develop the disease as men with no copies. Image: ACDbio

Right on target: New era of fast genetic engineering

Posted on 27 Jan 2014 in Featured, Genetics, Health, Journalism

Last month, two groups announced that they had performed a mind-boggling feat. They targeted and disabled nearly every one of our genes in cells growing in a dish. The genetic engineering tool used to perform the task has been in development for little more than a year – but it promises to revolutionise gene editing. Image: Martina Gobec
