One Year on, Scientists Defend Canada’s Anti-Genetic Discrimination Law

Article

The Canadian Genetic Non-Discrimination Act (GNA), introduced last May, made it illegal to require individuals to disclose genetic test results or to compel individuals to undergo genetic tests for any agreement or service. However, a subsequent legal challenge has prompted a robust defense of the act from scientists in the May issue of the Canadian Medical Association Journal (CMAJ).

Bird and Turtle Chromosomes Help Identify Dinosaur DNA

Bird and Turtle Chromosomes Help Identify Dinosaur DNA

News

Researchers have used bird and turtle DNA to extrapolate the chromosome structure of their common ancestor that lived around 260 million years ago – 20 million years before the dinosaurs first emerged. They were then able to trace the evolution of avian and non-avian dinosaur DNA through to the present day.

Schizophrenics' Blood Contains RNA From More Microbes
News

The blood of schizophrenia patients features genetic material from more types of microorganisms than that of people without the debilitating mental illness, research at Oregon State University has found. What’s not known is whether that’s a cause or effect of the severe, chronic condition that strikes about one person in 100.
