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 ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to switch genes on and off with exquisite precision. The latest work on ...

In a quiet lab at Utrecht University, researchers have built a tool that lets you watch one of life’s most serious crises ...

In two experiments, researchers have found that introducing people to "mental models" about how mRNA vaccination works and ...

A live C. elegans animal with the mitochondria in its nervous system decorated with red and green fluorescent proteins. “Mitochondrial DNA is essential for cell function,” Dr Hahn said. “But as we age ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

This may be about as wildly entertaining, disruptive and philosophically profound as legitimate scientific research gets. Michael Levin's work in cellular intelligence, bioelectrical communication and ...

A novel blood test analyzing fragments of cell-free DNA showed robust diagnostic performance for colorectal cancer across clinical subgroups, offering a promising noninvasive screening method.

Mitochondria are well known as the powerhouses of the cell because of their energy generating capabilities. These little ...
