It's been reported that astronaut Scott Kelly no longer has the same DNA as his twin brother after spending a year in space.
The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
Most men, women and children in Canada exceed the tolerable upper limits of salt for their bodies. Consumers need to understand how much salt is too much -- to avoid hypertension and heart disease.
What might first seem unarguable starts to look shaky when you bring twins into the equation.
Genetic research could help us produce new ways of diagnosing and treating depression and suicidal ideation – including a 'death smell test'.
Handedness is the tendency to prefer using one hand over the other to perform certain tasks. But how did we get this way?
Research shows that the Y chromosome may be able to protect itself from extinction in the short term. But what about in a future where we all reproduce artificially?
From a certain perspective, we're already on the road to practicing a 'progressive eugenics' not a million miles away from what was imagined historically.
Scandinavia was populated by two main migrations, making its first inhabitants more genetically diverse and adapted to harsh climates than those in the rest of Europe.
Research shows that children attending schools with low-quality food environments, in poorer neighborhoods, gain more central body fat -- putting them at risk of obesity and cardiometabolic disease.
The rapid growth of genetic testing and data-gathering could revolutionize health and medicine if governments work to protect people against privacy and societal risks.
Do you own your own genetic data? The future of genomic databases is almost here, and now is the time to figure out how we are going to allow this information to be used.
Over half the calories humans eat today come from corn, wheat and rice. Raising a greater diversity of types of crops and animals (agrobiodiversity) makes diets healthier and farming more resilient.
New research suggests Dolly's cloning process didn't create health problems.
Cystic fibrosis, spinal muscular atrophy and fragile X syndrome are serious diseases, and most couples carrying the genetic mutations for these don't know it. Should they all be tested?
A group of fewer than 800 orangutans in northern Sumatra has been recognised as a new species - and they are already under threat from deforestation.
The 2017 Prime Minister's Science Prize winner is genetic researcher Professor Jenny Graves, well known for her 2002 suggestion that the male Y chromosome will self-destruct.
I try to learn who are the ancestors of Indonesian people through genetics. The genetics of Indonesian people are a mix between different groups of humans.
A rush of ancient DNA projects in Africa has presented the curators of archaeological skeletons with ethical issues because research requires the destruction of human bone.
Can you blame bad teeth on your genes? Here's why the answer is not as simple as you might think.
