Scientists develop tool to sequence circular DNA

A new tool invented by University of Alberta biologists to sequence circular DNA will provide scientists with richer, more accurate data that could help advance research on viruses, agriculture and perhaps even cancer.

Images reveal how bacteria form communities on the human tongue

Using a recently developed fluorescent imaging technique, researchers in the United States have developed high-resolution maps of microbial communities on the human tongue. The images, presented March 24 in the journal Cell ...

New world map of fish genetic diversity

An international research team from ETH Zurich and French universities has studied genetic diversity among fish around the world for the first time. Their research produced a map that will serve as a tool in improving the ...

Simplifying simple sequence repeats

Simple sequence repeats (SSRs) are regions of DNA with high diversity, and they have long been a mainstay for botanists examining the genetic structure of plant populations. However, as the cost of sequencing DNA continues ...
