Liquid biopsies are tests that detect signs of cancer through a simple blood draw. Unlike traditional biopsies, which require removing a piece of tissue, a liquid biopsy typically looks for mutations ...

A new liquid biopsy developed by researchers at the University of Chicago is offering a powerful new window into cancer’s earliest stages by flagging subtle shifts in the gut microbiome. Unlike ...

With the rise of DNA ancestry tests, it’s easier than ever to learn about your family history and connections. Today, there are many DNA testing services to choose from. They're easy to use. You’ll ...

Liquid biopsies have transformed cancer testing. These tests detect signs of cancer using a simple blood draw instead of removing tissue from the body. Traditional biopsies involve surgery, needles, ...

The Human Genome Project changed everything. A map of the entire human sequence of DNA was the starting point for an enormous number of discoveries, from disease genes to how humans evolved. But DNA ...

Genome editing is a powerful biotechnology tool that allows scientists to make precise changes to an organism's DNA. It involves the use of specialized enzymes, known as engineered nucleases or ...

The discovery of CRISPR-Cas9’s gene-editing prowess revolutionized genetic engineering just over a decade ago. Now it appears that genetic engineering technology may be taking its next big leap.
