Some of the signs of aging in human cells originate in the cell nucleus, because the packaged form of DNA changes with age.

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 ...

In a recent landmark study, scientists have unveiled how HIV-1 penetrates the cell's nuclear barrier—a discovery that could reshape antiviral strategies. The research, led by Professor Peijun Zhang, ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

A study headed by researchers at NYU Langone Health has found that herpes simplex virus 1 (HSV-1) partially liquifies the tightly packed, gel-like interior of human cell nuclei to help copy itself ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

An illustration of multicolored tangle of threads within a small black sphere. A 3D illustration shows DNA packaged into the nucleus, scientists with the 4D Nucleome project are now building accurate ...
