According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...
Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots ...
DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...
Since the dawn of the computer age, researchers have wrestled with two persistent challenges: how to store ever-increasing reams of data and how to protect that information from unintended access. Now ...
In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...
Authorities confirm the DNA belongs to Nancy Guthrie, 84, who was last seen on Jan. 31 at her home in Arizona A sheriff in Arizona tells PEOPLE that investigators discovered "biological DNA" evidence ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated over and over, become longer and more unstable as we age. The study found ...
Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...
And it doesn't stop at heart tissue damage repair. “By enhancing DNA repair, we can heal tissue damage that occurs during a heart attack,” Ibrahim said. “We are particularly excited because TY1 also ...
