Christine Jessop was murdered in 1984 and, 36 years later, DNA evidence finally identified her killer. But the police investigation's use of genetic genealogical databases raised questions about privacy.
Epigenetic clocks are a fascinating new technology, but some potential applications are controversial.
Pediatric epigenetic clocks have the potential to accurately assess biological age. However, possible applications in law enforcement and immigration raise ethical issues.
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.
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.
Genetic testing costs around A$700 per embryo.
Women aged over 35 are sometimes offered genetic testing of their IVF embryos to rule out abnormalities. But it's expensive and doesn't increase their chance of a baby. In fact, it could reduce it.
No gene for cuteness has yet been identified – but give it time.
It's now possible to choose embryos for IVF based on the likelihood they will have certain traits.
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.
Men with faults in their BRCA2 gene are at higher risk of aggressive prostate cancer.
More than 200 gene variants have been linked to outstanding sporting performance and this number could increase as we continue to research the link between genetics and athlete performance.
Genetic testing could help us build targeted and effective training routines for athletes, but the emerging science could also introduce opportunity for discrimination in the sporting world.
Scientists explain why commercial gene testing should be used with caution.
Is it worthwhile to know you’re 25% Irish?
We asked five experts if DNA testing was worthwhile. Four out of five said yes.
A child with epilepsy during a seizure.
About 470,000 children in the US have epilepsy. Promising advances are being made in the field of epilepsy treatment for children.
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.
Every child born in the U.S. has a blood sample taken to screen for genetic diseases.
What happens when babies are born critically ill and the doctors have no idea what is wrong? Some argue that a controversial tool called whole genome sequencing may help find the cause.
If you’ve got the raw data, why not mine it for more info?
New research investigated who uses the wide array of tools available to people who've received their own raw genetic data and want to maximize what they learn from it.
Swamp foxtail is prized in ornamental gardens across Australia.
Present in Asia and Australia, the origins of swamp foxtails have not always been clear. Genetic studies put uncertainties to rest.
The cause of many inherited eye diseases are a mystery.
The causes of most inherited forms of blindness are unknown. Now more than 260 genes never before linked to eye development could lead to new therapies and diagnostics.
Does a good marriage depend on having the right genes?
Will your marriage be better if you and your partner are genetically compatible? Is there any evidence that certain genes make someone a better or worse partner? And if so, which genes should we test?
When you share your genetic data – even with the NHS – you don't know where it will end up, or how it will be used.
Genetic information is relevant not only for an individual, but also their blood relatives, because it’s often hereditary.
Because genetic changes that cause cause health complications can be hereditary, the information affects not only the person with the mutation but also their biological relatives.
