DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

HPV-DeepSeek shows promise for early detection of head and neck cancer

Human papilloma virus (HPV) causes around 70% of head and neck cancers in the United States, making it the most common cancer caused by the virus, with rates increasing each year.

Researchers reveal why no level of air pollution is safe for respiratory health

A review in the Journal of Clinical Investigation shows how particulate matter damages the lungs through oxidative stress, inflammation, and immune disruption. It links air pollution to asthma, COPD, lung cancer, infections, and millions of premature deaths, with no safe exposure threshold.

Monitoring ctDNA can personalize the use of consolidation immunotherapy in patients with LS-SCLC

A new study presented at the International Association for the Study of Lung Cancer 2025 World Conference on Lung Cancer (WCLC) demonstrates that monitoring circulating tumor DNA (ctDNA) can refine and personalize the use of consolidation immunotherapy in patients with limited-stage small cell lung cancer (LS-SCLC).

‘Rogue’ DNA rings identified as drivers of aggressive brain cancer

An international team of scientists has revealed how rogue rings of DNA that float outside of our chromosomes – known as extrachromosomal DNA, or ecDNA – can drive the growth of a large proportion of glioblastomas, the most common and aggressive adult brain cancer.
