This is a detailed 3D-structure of the herpes virus: the capsid or protein shell, which contains the virus DNA, is surrounded by several envelope layers.
The genome encodes the complete information needed by an organism, including that required for protein production. Viruses, which are up to a thousand times smaller than human cells, have considerably smaller genomes. Using a type of herpesvirus as a model system, the scientists of the Max Planck Institute of Biochemistry in Martinsried near Munich and their collaboration partners at the University of California in San Francisco have shown that the genome of this virus contains much more information than previously assumed. The researchers identified several hundred novel proteins, many of which were surprisingly small.

Like a homeowner prepping for a hurricane, the bacterium Bacillus subtilis uses a long checklist to prepare for survival in hard times. In a new study, scientists at Rice University and the University of Houston uncovered an elaborate mechanism that allows B. subtilis to begin preparing for survival, even as it delays the ultimate decision of whether to "hunker down" and withdraw into a hardened spore.
