The last common male ancestor of all humans is far older than previously thought, scientists have found. When the family of Albert Perry, an African-American living in South Carolina, submitted his DNA to commercial genealogy company Family Tree DNA, it was discovered that his Y chromosome was so distinct that his male lineage likely separated from all others around 338,000 years ago.
The scientific community has raised concerns about the state of UK immigration after a number of academics attending the Global Symposium on Health Systems Research were denied access to the country recently.

Travel allows us to see the world – and bring foreign diseases home. Here’s why spreading disease is easier than ever.
Starting about 7,000 years ago, and extending over the next two millennia, recent studies suggest, the genetic diversity of men—specifically, the diversity of their Y chromosomes—collapsed.
A new analysis of DNA sequences suggests the Native American founding population that migrated from Siberia consisted of approximately 250 people.
While some people are warning about artificial intelligence leading to killer robots, researchers are showing the positive impact of A.I. in its potential to overcome disease.
