What’s the best way to put the brakes on current research?
Scientists and ethicists have called for a five-year moratorium on editing human genes that will pass on to future generations. Yes, society needs to figure out how to proceed – but is this the best way?
New technology means accessing new information from ancient human remains, some which have been in collections for decades.
Ancient DNA allows scientists to learn directly from the remains of people from the past. As this new field takes off, researchers are figuring out how to ethically work with ancient samples and each other.
Genetics is influencing more and more of our decisions, but we can't make the right choices if we don't understand it.
Lake Mungo and the surrounding Willandra Lakes of NSW were established around 150,000 years ago.
New techniques for genetic analysis are helping us build more detailed and accurate stories about the ancient histories of the first Australians.
When a cell divides, mitochondria are randomly allotted to the resulting new cells.

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.
Roughly 10 per cent of the population is left-handed, like President Barack Obama, seen here signing the guest book on Parliament Hill in Ottawa in June 2016.

Handedness is the tendency to prefer using one hand over the other to perform certain tasks. But how did we get this way?

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.
With all these ‘test-tube babies’ grown up, how have our reactions to the technology evolved?

Americans have moved on from worrying about ‘test-tube babies’ – but there are still ethical challenges to resolve as reproductive technologies continue to advance.
There’s still a way to go from editing single-cell embryos to a full-term ‘designer baby.’
The news may have come as a surprise, but it probably shouldn't have. A bioethics expert walks through how big a deal this announcement is – and what we should be considering now.
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
Unravelling the common assumption that runners from Kenya, Ethiopia and Somalia have a natural advantage.
DNA Nation raises questions of genetics, identity and race.
The SBS documentary DNA Nation tracks three people on their 'individual genetic journey'. But for Indigenous Australians in particular, genetic testing is a can of worms - politically, ethically and technically.
People get suspicious when ethically fraught science is discussed behind closed doors.

A recent closed meeting about building synthetic genomes raised suspicions about just what scientists were planning, away from the public eye.
Study finds that gene linked to risk-taking is associated with losing your virginity early.
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.
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.
A DNA string. The genomic revolution is upon us.
The discovery made by three Nobel Prize winning chemists is one of biology's most important safeguards against imperfection in DNA.
The 1000 Genome Project is comparing the genomes of thousands of people from around the world.
The 1000 Genome Project has revealed the genetic variations that exist among people around the world, and discovered that some people are missing many genes.
US row might suggest using feotal tissue is new - in fact it's not only a long-held practice, but essential for many medical breakthroughs.
