For the first time, scientists have used DNA preserved in ancient sediments to examine how a major natural disaster affected ...

In 1994, the remains of 1st Lt. Michael Joseph Blassie, an airman killed in the Vietnam War, were identified and confirmed by DNA testing in 1998. He was exhumed and reburied closer to his family. It ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

Before the DNA revolution of the early 2000s, genealogy was a study dependent on records. Tracing a line of heritage could hit a dead end if documentation had gone missing or been destroyed. But as ...

The single-stranded DNA molecules developed by researchers using the SELEX technology could transform blood testing for Alzheimer's biomarkers. These synthetic aptamers target neurofilament light ...

If they have no ancestors or descendants, then who are they?

Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to separate ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...
