The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Circulating Tumor DNA as a Prognostic Biomarker for Recurrence in Patients With Locoregional Esophagogastric Cancers With a Pathologic Complete Response PD-1 inhibition is effective in patients with ...

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Irvine, Calif., Dec. 3, 2024 – A research team co-led by the University of California, Irvine has discovered that accumulated DNA damage in the retina is a key contributor to age-related macular ...
