| Turning off small RNA: New tool designed for breaking the epigenetic code Posted: 01 Mar 2012 11:37 AM PST Scientists have known for years that minuscule strings of genetic material called small RNA are critically important to our genetic makeup, but finding out what they do hasn't been easy. Now scientists have developed a way to turn off small RNAs and find out just how important they can be.  |
| Clearer picture of how protein machine systems tweak gene expression Posted: 01 Mar 2012 11:37 AM PST Biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.  |
| Bacteria communicate by touch, new research suggests Posted: 01 Mar 2012 11:37 AM PST What if bacteria could talk to each other? What if they had a sense of touch? A new study suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions.  |
| Protein complex affects cells' ability to move, respond to external cues Posted: 01 Mar 2012 11:33 AM PST Scientists have explained for the first time how a long-studied protein complex affects cell migration and how external cues affect cell's ability to migrate.  |
