Genetics tools have advanced significantly in recent decades, and have allowed scientist to sequence all of the genetic material they find in any sample. That has enabled researchers to discover giant ...

CRISPR-Cas9 is a customizable tool that lets scientists cut and insert small pieces of DNA at precise areas along a DNA strand. This lets scientists study genes in a specific, targeted way. (NHGRI via ...

Human DNA is not always making us function in ways we understand. Some of our genome is just there, and we’re not sure what it does. In fact, 8% of our DNA are viruses our ancestors caught one day and ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology. They carry genetic material, but they cannot make proteins on ...

Viruses rely on hosts to survive. But some viruses are more effective at reproducing than others. Now, new research has shown that the herpes virus, more specifically herpes simplex virus type 1 ...

Researchers at Aarhus University have developed a microscopic DNA needle that can deliver molecules directly into cells—and, crucially, help make sure they remain active once they get there. That ...
