Although DNA evidence collected in the Nancy Guthrie investigation has yet to yield matches, law enforcement is still bracing for results that could expose cracks in the southern Arizona case ...

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 ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...

“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...

James Dewey Watson, a molecular biologist whose work helped decode the structure of DNA, died on November 6, 2025, at a hospice in East Northport, N.Y. He was 97 years old. Watson was best known for ...

This statement might sound like a line from a sci-fi movie, but what if life on Earth didn’t start here at all? For decades, that question sat on the fringe of science, it was filed next to crop ...

Summer McKesson struggled to breathe for years. Doctors told her it was because her blood would not stop clotting – and they couldn’t figure out why. A single clot alone can be lethal; but the ...

Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...

For years, Customs and Border Protection agents have been quietly harvesting DNA from American citizens, including minors, and funneling the samples into an FBI crime database, government data shows.

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
