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 ...

"Our new tool allows us to study how changes in mitochondrial abundance and the mitochondrial genome affect cells and organisms," said Jun Wu, Ph.D., Associate Professor of Molecular Biology at UT ...

AMOLF researchers discovered a mysterious interplay of insulin signals in the worm C. elegans. The insulin-driven protein DAF-16 does not only move in and out of the cell nucleus in a complex rhythm, ...
