More people are sending off saliva samples to find out about their genetic roots. But the raw DNA results go way beyond genealogical data – and could deliver unintended consequences.
Men who take risks are more likely to eat in response to unpleasant emotions.
Folic acid in pregnancy – and the gene which explains why the benefits may differ.
Our ability to reconstruct physical features from DNA is advancing, but can we ensure the privacy of "anonymised" genetic data if we can predict the face of its owner?
We're at the point in DNA technology where individuals who – having parted with $99 and a small vial of saliva – may suddenly find themselves in a criminal investigation.
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.
Scientists are just starting to understand how your parents' genes and experiences might shape your own susceptibility to dangerous drugs. Could that help to stop addictions before they start?
From genes to wounds, science is making it easier to establish the order of events in criminal cases.
New research shows just 1% of E. coli bacteria's genetic mutations are lethal.
A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
Each discipline tells us only part of the story. And so the truest picture of prehistory comes from triangulating these independent lines of evidence.
We can either take advantage of advances in technology to enhance human beings (never to go back), or we can legislate to prevent this from happening.
They were discovered over 100 years ago – but we still don't know exactly what genes are.
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?
