Technology that can identify stray bits of genetic material in the environment can help scientists monitor human and animal health.
COVID-19 tests rely on a process developed at a biotech company co-founded by a Canadian. Canada’s current testing expertise needs to be channelled to prepare for the next wave, and the next pandemic.
My international research project was put on hold – so I volunteered to become a COVID-19 tester. Here’s what I learned.
Traditional water quality test results tell you what was happening at the beach yesterday. More real-time answers can be a boon for public health.
Genetic evidence has become a critical aspect of modern criminal investigations. What are the methods and approaches used in present-day DNA forensics?
Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
Forget the pith helmet and butterfly net. Discovering biodiversity now is much more about metagenomics and the 0’s and 1’s of digital databases.
