Both Macron and Madonna have expressed concerns about genetic privacy. As DNA collection and sequencing becomes increasingly commonplace, what may seem paranoid may instead be prescient.
Many researchers are interested in the genetic history of the Khoe-San.
The South African Khoe-San communities are no strangers to exploitative research. One research team is trying to provide genetic ancestry results to community members. But they still face many challenges.
Skin conditions like psoriasis and eczema can have rashes that are difficult to distinguish by eye.

Many doctors currently diagnose skin conditions by eye. Advances in molecular testing could lead to more precise and accurate diagnoses for ambiguous rashes and skin lesions.
Redditors are eager to share their perspectives, knowledge and experiences of non-invasive prenatal testing.
Non-invasive prenatal testing can assess risk for genetic anomalies in a fetus. But interpreting risk levels is highly personal, as a study on Reddit discussions shows.
Genetic testing of embryos during IVF doesn’t increase the odds of having a baby. But there are a number of downsides, including cost.
Australia risks being left behind in the genomic medicine revolution by failing to protect individuals from genetic discrimination.
New Zealand is out of step with the rest of the world in its consumer protection against genetic discrimination in insurance.
It may not be long before Australia’s health sector offers predictive genomic analysis to patients. If this happens, could chatbots help lessen the load on genetic counsellors?
New DNA analysis revealed that Calvin Hoover killed Christine Jessop in 1984. Toronto Police Chief James Ramer sits next to a screen displaying photos of Calvin Hoover during a news conference on Oct. 15, 2020.

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.
