Here is today's scientific image:
This delicate, fluffy object is a cytoskeleton viewed under a fluorescence confocal microscope. Below is a time-lape video of the process. For an explanation of why the cell's actin fibers twist around into this shape, go to our website.
Indeed, all three of today's new articles involve crucial cellular dynamics: cutting up unfolded proteins with pared-down molecular "scissors" and binding to metal ions in proteins. In other words, within that lovely shell-like cytoskeleton, the cell is quite a busy place, with loads of activities still to explore. Have fun!
