In work conducted at both UC Santa Barbara and the Physics of Life Excellence Cluster of TU Dresden, biophysicist Otger Campàs and his research group have found that cell nuclei control the ...

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 ...

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 ...

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 ...

Around one million individuals worldwide become infected with HIV, the virus that causes AIDS, each year. To replicate and spread the infection, the virus must smuggle its genetic material into the ...

Because viruses have to hijack someone else’s cell to replicate, they’ve gotten very good at it—inventing all sorts of tricks. A new study from two University of Chicago scientists has revealed how ...
