People with a common history – often due to significant geographic or social barriers – often share genetics and language. New research finds that even a dialect can act as a barrier within a group.
The genetic evidence behind why some people suffer longer term concussion effects is growing. But what are the ethical considerations that flow from that knowledge when it comes to sport?

People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.
The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.
Fundamental research has informed what we know about coronaviruses up until the pandemic. With possible future outbreaks, continuing and developing this type of work is crucial.
Africa is known to be where humans originated. This makes it the most genetically diverse region in the world. Diversity in other populations represents a subset of the diversity within Africa.
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
Scientists of all kinds turn to computer models to investigate questions they can’t get at any other way. Here’s how models work and why we can trust them.
Despite science refuting the existence of different human races, people have used “race” throughout history to divide and denigrate certain people while promoting their claims of superiority.
