In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Scientists from Skoltech and the University of Potsdam have developed a physical theory that sheds light on how molecular ...

A machine learning model analyzing CpG-based DNA methylation accurately predicted the origin of many different cancer types ...

Diagnosis requires a tissue biopsy for histopathologic and immunohistochemistry evaluation. Testing for alterations using non-small cell lung cancer (NSCLC) tumor tissue requires acquisition of a ...

Drawing inspiration from natural cell signaling cascades, chemists at Université de Montréal (UdeM) have developed a DNA-based signaling cascade that allows them to quantify and report via an easily ...

Researchers at Boston University have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may ...

MethylScan is a low-cost blood test that detects cancers and organ diseases by analyzing DNA methylation, improving early diagnosis, and identifying disease origin.

In April 2026, a team of bioengineers at the Georgia Institute of Technology unveiled a genetic security system that works ...

A circulating tumor DNA (ctDNA) test showed promise in identifying which older patients with estrogen receptor–positive ...
