| Deep-reef coral hates the light, prefers the shade Posted: 16 Oct 2011 06:20 PM PDT Bird's nest coral is common throughout the Indo-Pacific and is able to live across a range of depths. New research used genetic and photosynthetic analysis to demonstrate that the genetic differences between both bird's nest corals and their algal symbionts, which provide energy for the corals to survive, reflect adaptations to the different environmental conditions encountered at different depths.  |
| New role for RNA interference during chromosomal replication discovered Posted: 16 Oct 2011 10:20 AM PDT Scientists have described a new role for RNAi during chromosomal replication. They have now shown that RNAi allows the DNA replication fork to progress smoothly without resulting in DNA damage.  |
| Precise gene therapy without a needle Posted: 16 Oct 2011 10:20 AM PDT For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle. The technique uses electricity to "shoot" bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.  |
