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?
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.
A new treatment for achondroplasia is helping to transform many kids' lives.
A collaboration between research and industry has produced a promising new drug that could transform many childrens' lives. It's also a case study in innovation done right.
‘Franken Mozzie’ goes under the spotlight.
The ethics of genetically modified mosquitoes and the gene-drive technology that seeks to spread them.
New genetic technology could change the DNA of entire species to prevent them from spreading diseases.
Effects may vary.
Why does the same medication, at the same dose, work well for some people, but not for others? The answer is in our genes.

Cats share some important genes associated with herbivores – this might explain their particular eating habits.
Microbes can act as canaries in the coalmine for ocean pollutants such as sewage.
There are more bacteria in the ocean than stars in the known universe. New genetic techniques are letting us use microbes as early warning systems for oceans in trouble from pollution and other stresses.

A new study has looked at the 'father effect' in epigenetics.
Who’s a clever boy?
The study of human intelligence dates back well over 100 years. And the core disagreement between researchers and theorists is whether differences are genetic or largely influenced by the environment.
People who believe their problems have biogenetic causes tend to opt for biomedical treatments.
Biological and genetic explanations of mental illness can weaken people’s sense of control and optimism, and create a bias against effective psychological interventions.
