| Need for speed: Molecular ticket determines RNA’s destination and speed inside egg cell Posted: 18 Mar 2012 11:40 AM PDT Like any law-abiding train passenger, a molecule called oskar RNA carries a stamped ticket detailing its destination and form of transport, scientists have found. They show that for this molecule, moving in the right direction isn't enough: speed is of the essence. Their study also provides clues as to how a single molecule could receive tickets for different destinations, depending on what type of cell it is in.  |
| Surprise: Protons bypass hydrogen bonds but still change molecules Posted: 18 Mar 2012 11:39 AM PDT Common wisdom has it that protons only travel between molecules via hydrogen bonds: no hydrogen bonds, no proton transfer. Scientists investigating molecular components of RNA were surprised to find that protons can find ways to transfer even when hydrogen bonds are blocked. The discovery may open new opportunities for research in biology, environmental science, and green chemistry.  |
