Technology that can identify stray bits of genetic material in the environment can help scientists monitor human and animal health.
In Canada, watersheds are vast and often inaccessible, making it difficult to monitor the health of these ecosystems. A new tool helps communities collect data to assess the state of Canada's rivers.
DNA sequencing means a scientist can take a bucket of seawater and ID every fish in the area. Now we need a universal 'biobank' of samples to make a truly powerful environment monitoring tool.
If you're committed to a belief, it's hard to let go. Psychology and philosophy provide different ways to think about how skeptics respond to counterevidence.
We cannot spot every shark in the ocean. But we can detect their 'environmental DNA'.
Food fraud is a common problem that technologies such as blockchain and DNA fingerprinting can help to solve.
By 2167, DNA barcoding scans will lead to weather-style "biodiversity forecasts," enabling us to more easily protect and care for the environment.
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.
Scientists are pioneering a new way of monitoring water species, using techniques more familiar to fans of crime scene TV shows.
