DNA barcoding

A new method traces treatment resistant cells and predicts drugs that can make them more susceptible to cancer therapy.

A simple rainforest leaf swab revealed DNA from dozens of animal species, possibly improving biodiversity monitoring in the future.

In a trio of studies, researchers report capturing and analyzing airborne environmental DNA from a wide variety of plants and animals, suggesting a new way of monitoring which terrestrial species are present in an area.

A New York Times investigation’s failure to amplify tuna DNA from Subway’s tuna salad sandwiches likely says more about the complexities of identifying processed fish than about the ingredients.

A proof-of-concept study uses eDNA in the air to detect mammals, expanding the technique beyond aquatic sampling.

Researchers combine organoids, CRISPR-Cas9, and cellular barcoding technologies to identify genes that influence brain size.

The newly minted Baylor College of Medicine faculty member is working to crack the mystery of triple negative breast cancer.

Monitoring the comings and goings of aquatic life with traces of DNA in water has become an established biomonitoring technique, but scientists are now using environmental DNA to assess terrestrial animals.

The discovery of ancient clades of brittle stars at the bottom of the Pacific Ocean adds to concerns that commercial exploitation of the area could destroy numerous taxa before they’ve even been identified.

A group of scientists in northern Norway are using the technique to measure biodiversity’s response to past and present climate change.

Scientists examine floating traces of DNA left by fish to better understand New York’s aquatic life.

Scientists create a CRISPR-based, self-editing cellular–barcoding system for extensive molecular recording.

A study of black widow spiders suggests that the arachnids leave traces of their own genetic material and DNA from prey in their sticky webs.

Degraded DNA from museum specimens, scat, and other sources has thwarted barcoding efforts, but researchers are filling in the gaps with mini-versions of characteristic genomic stretches.

Watch DNA barcoder Mehrdad Hajibabaei from the University of Guelph describe the technology’s potential.

Scientists have identified a species of cockroach never before seen in the U.S., which was spotted last summer on Manhattan’s West Side.
