HHMI researchers develop a new single-cell imaging technique that reveals the copy numbers and locations of thousands of RNA molecules inside a cell.
Scientists have discovered that periodic ring-shaped actin arrangements encircle the long axonal fibers of nerve cells, in contrast to the linear meshworks that typically give cells their shapes.
New images from HHMI scientists show the stunning dynamics of HIV reverse transcriptase zooming around on the very DNA it is building.
A new microscopy technique allows researchers to examine the complete three-dimensional morphology of many of the tiniest structures of cells.
A colorful new palette of fluorescent tags promises to give researchers a better view of life at the molecular level.
It can take hours, or even days, for a virus to infect a cell. But poliovirus is more efficient than the average virus.
Scientists have recorded the action involved in assembling telomerase, an enzyme used by cells to protect their genes during the potentially dangerous process of DNA replication.
