You shed DNA everywhere you go – trace samples in the water, sand and air are enough to identify who you are, raising ethical questions about privacy

Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.

Uncovering the genetic basis of mental illness requires data and tools that aren’t just based on white people – this international team is collecting DNA samples around the globe

Existing genetic data and sequencing tools are overwhelmingly based on people of European ancestry, which excludes much of the rich genetic variation of the world.

Where coronavirus variants emerge, surges follow – new research suggests how genomic surveillance can be an early warning system

By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.

Genomic surveillance: What it is and why we need more of it to track coronavirus variants and help end the COVID-19 pandemic

The US lags in testing coronavirus samples from COVID-19 patients, which can help track the spread of the virus and the emergence of new variants. But labs are ramping up this crucial surveillance.
