Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

Biosensors reveal how single bacterium gets the message to split into a swimming and a stay-put cell
Some species of bacteria perform an amazing reproductive feat. When the single-celled organism splits in two, the daughter cell - the swarmer - inherits a propeller to swim freely. The mother cell builds a ...
