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 ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is densely packed with biomolecules like proteins and nucleic acids. How is ...

The image shows the cross section mutant brown adipose tissue section with enlarged lipid droplets (yellow) and nucleus (blue) being impinged by multiple mitochondria (red). Mitochondria are ...

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this ...

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest ...

The investigations of KIT researchers have shown that biomolecular condensates enable fast yet reliable activation of the right genes. “Biomolecular condensates are tiny drops that form in specific ...
