Direct-to-consumer genetic testing can help scientific researchers.
Scientists who work in local companies have acquired local knowledge and are therefore able to work with South Africa's unique genetic diversity better than anyone else.
It has long been recognised that mental disorders can run in families. And often members of such families differ in their symptoms.
Research on the genetic basis of mental illness has so far largely excluded anyone who is not of European heritage.
Genetic testing in Banff National Park showed that grizzly bears were using wildlife corridors for safe passage beneath a highway.
Information collected from DNA samples can be used to identify species, track their movements and diagnose genetic diseases. This information is useful in conservation and management projects.
DNA from relatives could be used in sentencing offenders.

When DNA databases and behavioural genetics combine, your family's genes could play a role in criminal sentencing
Individuals who upload their DNA test results to databases may not have much control over how it’s used.
Can the new owner of GEDmatch ,a genealogy database preserve its original purpose while allowing a seamless service to law enforcement?
No, a DNA swab can’t tell you if you’re gay, or likely to be obese, or depressed. And it can be damaging to believe so.
Genetic apps claim to reveal fundamental insights about your health, well-being, and even intellect. But it's not just spurious science - believing these traits are genetic can have harmful consequences.
DNA database giant Ancestry lets members access international records including the convict and free settler lists, passenger lists, Australian and New Zealand electoral rolls and military records.
A US judge has allowed police access to the major DNA database without users' consent (including Australian users). It's a timely reminder that we urgently need genetic privacy legislation.
Australian women and children are said to be among the estimated 72,000 people at the Al Hawl camp in Syria.

DNA testing gives limited information about whether people are likely to be related. But even if we overcame the many practical and legal hurdles to implementing it, what's the point?
Is it worthwhile to know you’re 25% Irish?
We asked five experts if DNA testing was worthwhile. Four out of five said yes.
Polygenic risk scores currently account for only a small proportion of your total genetic risk.
Most common chronic diseases are the outcome of complex interactions between genetic, environmental and social risk factors, so a genetic risk score, on its own, isn't much help.
What are the rules that make a man a father?
Before the advent of genetic testing, definitions of paternity were primarily social and legal. Science has destabilized these older definitions, but it has not replaced them.
We’ve underestimated the extent of mixing between ancestral groups throughout human history.
Estimating our ancestry is hard – because our backgrounds are much more mixed up than we thought. So don't take your DNA ancestry test results literally: they're just a prediction.
Some American Indian tribes, including the Navajo Nation, have moratoriums on genetic testing.
Why is Elizabeth Warren's DNA test so controversial with Native American groups? Two Indigenous geneticists explain the history and science behind the debate.
Genetic ancestry testing might all seem like harmless fun, but there is a downside.
The results of genetic ancestry tests are grossly over-simplified. A new study shows the tests reinforce what you want to believe rather than offering objective, scientific proof of who you are.
Genetics is influencing more and more of our decisions, but we can't make the right choices if we don't understand it.

We now have the capacity to quickly and cheaply sequence an individual's genome and scour it for disease-causing genes. But how much, and what type, of information does a parent-to-be want to know?
Users may want to know more than what’s in a basic report from a genetic testing company.
Data and privacy issues are tangled up in the DNA reports consumers get from big genetic testing companies – and the third-party sites they turn to in order to glean more from their raw DNA.
It all begins with spitting in a tube like this one.

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.

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.
Listening to audio derived from DNA may help scientists better understand how cell biology works.
Converting a DNA sequence into an audio could help us learn something useful about it, like where mutations occur.
