High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Evo’s success wasn’t limited to proteins. When they tested a different toxin that had an RNA-based inhibitor, the system ...

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the 'dark genome' that are responsible for controlling how cells sense and respond to the ...

DNA might be too small to see with the unaided eye, but it packs our cells in shocking quantities: More than six and a half feet of DNA lies within every cellular nucleus. It squeezes into such a ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

ASH 2025 research shows cancer can arise not just from mutations but from broken DNA architecture. AI reveals how lost genome loops silence tumor suppressor genes.
