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 ...

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 ...

Around 8 percent of human DNA is made up of genetic sequences acquired from ancient viruses. These sequences, known as human endogenous retroviruses (or Hervs), date back hundreds of thousands to ...

Illinois researchers developed a nanorobotic hand made of DNA that can grab viruses for detection or inhibition. In this artist’s rendering, three “NanoGripper” hands wrap around a COVID-19 virus.

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 ...

Charles Darwin proposed that evolution is driven by gradual variations in organisms that have a survival advantage in a changing environment. But University of Maryland evolutionary biologist Karen ...
