The genetic evidence behind why some people suffer longer term concussion effects is growing. But what are the ethical considerations that flow from that knowledge when it comes to sport?
Ancient DNA preserved in the tooth tartar of human fossils encodes microbial metabolites that could be the next antibiotic.

Ancient microbes likely produced natural products their descendants today do not. Tapping into this lost chemical diversity could offer a potential source of new drugs.
The research and vision of Canadian scientists were key foundations of the Human Genome Project. Today, lack of funding threatens discovery research in Canada.

Humanity carries traces of other populations in our DNA – and a new study shows how one of these ancestors has influenced the immune systems of modern Papuans.
Statistical pitfalls in GWAS can result in misleading conclusions about whether some traits (like long horns or spotted skin, in the case of dinosaurs) are genetically linked.

People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.

A new study hopes to produce a catalogue of human genetic variation and assess the burden of noncommunicable diseases in 100,000 adults in Nigeria.
While resurrecting dinosaurs may not be on the docket just yet, gene drives have the power to alter entire species.

As genetic engineering and DNA manipulation tools like CRISPR continue to advance, the distinction between what science ‘could’ and ‘should’ do becomes murkier.
Ontario Chief Medical Officer of Health Kieran Moore arrives to speak at a press conference at Queen’s Park on April 11, 2022. Ontario lifted most COVID-19 restrictions in March.

Instead of minimizing current or future waves of COVID-19, we need strategies to deal with new variants efficiently. Only then can we live with the virus in a healthy way.
Over half of the human genome contains repetitive DNA sequences whose functions are still not fully understood.

After a nose swab tests positive for a virus or bacteria, scientists can use the sample’s genetic sequence to figure out where and when the pathogen emerged and how fast it’s changing.
Genetic analysis can reveal how hair gets its colour.
