Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.
Climate change is bringing heightened droughts, heat stress and floods. For our fruit trees, that means tougher conditions. To prepare means mining their genomes to hunt for resilience.
A Steller’s sea eagle, native to the Asian Arctic, has traveled across North America since 2021. A scholar questions whether the bird is lost – and how well humans really understand animals’ actions.
How to prove you’re descended from royalty.
A new study shows that the gut microbiota has little or no effect on our weight, metabolism and risk of developing chronic diseases.
The genetic study challenges previous theories about the origins and culture of the Picts.
On DNA Day, Canada should be inspired by the lifesaving discoveries of its researchers. However, lack of funding threatens Canadian researchers’ ability to meet the challenges of the future.
New genetic studies claim to be able to foretell our intelligence or predisposition to certain diseases. But two scientists beg to disagree, reminding us that not everything is written in our DNA.
Some animals appear to use a ‘parliament’ of genes to determine sex. But a closer look reveals these are the exception rather than the rule.
DNA analysis sheds light on important societies within Africa that existed before colonialism.
Our genetics, immune systems and conditions in the environment around us can all play a role in susceptibility to hay fever.
We can trace our human evolutionary lineage back to fish.
FTD leads to changes in personality and behavior. Understanding its genetic and molecular causes could lead to new ways to treat neurodegenerative diseases.
Kate Legge’s husband was chronically unfaithful. So was his father, who was forced to leave the family home after revealing his mother’s affair. Legge reflects on generational love and infidelity.
Medicine works better when the treatments are tailored to fit each individual person’s biology and history. A first step is increasing diversity in clinical trials, but the end goal is precision medicine.
An estimated 1-5% of people globally suffer from avoidant restrictive food intake disorder.
When species naturally hybridise, the influx of genes can reduce their risk of extinction as climate change shrinks their habitats.
The immortal jellyfish ‘Turritopsis dohrnii’ is capable of escaping death. The molecular keys involved in its longevity have been revealed by researchers at the University of Oviedo.
The risk of developing eye complications is high in young people with Type 2 diabetes, which is increasingly affecting children and adolescents, especially those who are more sedentary.
