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 ...

Jeffrey Epstein had a bizarre obsession with genetics and “improving” human DNA — and he was corresponding with top scientists to make his fantasies a reality. The newly released documents from the ...

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 ...

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 ...

Medical scientist Eduardo Marbán – then at Johns Hopkins and now Cedars-Sinai – found that heart progenitor cells also have a special mechanism where they send out sacs, known as exosomes, which carry ...

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 ...
