Cryo-Electron Microscopy Technique Helps to Study Biological Nano-Structures

UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution.

Scientists Discover How Cells Ensure Correct Distribution of Proteins Throughout their Interior

All life on earth is threatened by chaos. In this sense, a cell is like a ship which could at any moment sink in a sea of chaos. It must constantly consume energy to maintain the same level of order to avoid going under - metaphorically speaking, the infiltrating water of chaos needs to be pumped out, permanently.
