We all know that stress can wreak havoc on your health but what does it do to your genes?
Many babies are born with a genetic variant that leads to ambiguous sexual development.
Many babies are born with a genetic variant that can result in the child being neither a typical boy or girl. There has been considerable debate about whether the child should be treated.
Sometimes science needs to look at the bigger picture in order to best influence public policy.
Science is about more than protons, genes and neurons. Sometimes a bigger picture can help us make better decisions when it comes to public policy.
DNA analysis reveals that there are three populations of Antarctic blue whales.

Antarctica's blue whales all feed in the same place. But a new genetic analysis suggests they are actually three separate populations that breed in different parts of the globe.
A mouse embryo, like this one, looks a lot like that of a fish, a frog or a human at a certain point in its development.
Scientists have discovered the genetic "switch" that causes many animals, including fish, frogs and humans, to look the same at a certain point in embryonic development.
The mighty monobrow.
New study may lead to drugs that could alter hair growth, such as stopping hair loss.
Cassava feeds 800 million people - keeping it disease-free is a must.
Rapid genetic disease screening will be the key to saving East Africa's crops - just as it was during West Africa's ebola crisis.
A few genetic tweaks can solve a lot of problems.
Genetically modified animals can help to feed the world's burgeoning population, but there is still a lot of misinformation concerning its safety.
These workers are working on behalf of their queen. But why?
It's long been a mystery how queen bees stop their workers from laying eggs. The solution comes from understanding a gene we call Anarchy.
Cutting and pasting DNA – it’s a bit like fitting in LEGO blocks.

The biology and ethics of gene editing, explained by scientists.
Research on how our lifestyles affect our genes raises the possibility of giving your future kids a better start in life before they're even born.
Why do mosquitoes not suffer from the infections they pass on?
There's something about mosquitoes that means they don't get sick from the infections they carry. So can we turn that function off, genetically?
A family migrating to western US in 1886.
Humans evolved in Africa, spread across the world, and then it gets messy. Luckily advances in genetic sequencing have helped us track the complex history of human migration.
The X-chromosome at some point evolved to be different from all other chromosomes.
Unlike other chromosomes, the X chromosome is inactivated in nearly all cells in women – and genes on it are active in very few tissues.
Just thinking about death triggers odd behaviour, shows research.
It's a myth that hair and nails continue to grow after you die. What else have science discovered about death?
New research suggests how we could prevent genetically modified organisms from surviving - and potentially spreading - in the wild.

The International Summit on Human Gene Editing drew a distinction between editing an individual's body cells and editing germline cells that would pass changes to future generations. Does that make sense?
Is he really guilty if he had a genetic predisposition towards impulsive behaviour?
Biology is out of our control but can influence our behaviour. But should people be given shorter sentences because of their genes?
Future people would be grateful if their disease is cured, rather than being replaced by a different healthier or non-disabled person.
Experts from around the world are in the US to discuss the scientific, ethical and governance issues linked to human gene editing. Here are five reasons they shouldn't ban research in the field.
The real question is not whether gene editing should be allowed or banned, but how it should be regulated.
The debate about regulating gene editing technology is often couched in polar terms, but understanding degrees of regulation that might be a better approach.
