How do people get cancer?

What is cancer – the deadly disease that affects the lives of millions of people around the world each year? And… why do some people get it, and others not?

Although people can reduce their chance of getting cancer by making healthy lifestyle choices, unfortunately it is not possible to completely prevent it... and scientists are still not entirely sure why.

Once genetic lesions for diseases such as cystic fibrosis and haemophilia were identified, the idea of replacing or correcting defective genes grew into what we now call "gene therapy".

A major study of dingo DNA has revealed the animals most likely migrated to Australia in two separate waves – a find with significant implications for their conservation.

An international study has provided compelling evidence that we inherit more than a DNA blueprint from our mothers and fathers – we also inherit vital instructions on how to use this blueprint.

A wild-born, pure Australian desert dingo called Sandy Maliki has taken out first place in the World’s Most Interesting Genome competition. Her DNA will be decoded using the latest genome sequencing technology.

Explorers from UNSW and Britain have discovered a colony of wild St Bernard dogs in a remote mountain range in southern Siberia – a remarkable find given St Bernards were previously thought to be native to Switzerland.

UNSW and Harvard researchers have identified a critical step in the molecular process that allows cells to repair damaged DNA – and it could mean big things for the future of anti-ageing drugs, childhood cancer survivors and even astronauts.

It’s no exaggeration to say that genetic research is rewriting our understanding of the human evolutionary story, writes Darren Curnoe.

The discovery that starlings carrying a new mutation in their mitochondria, the energy powerhouses of cells, almost tripled their population within five years has important implications for mitochondrial diseases in humans.
