Scientists mark 50 years since key RNA discovery
01-09-2007 · Massachusetts Institute of Technology (MIT)Profound doubts were the frequent response when MIT biophysicist Alexander Rich announced 50 years ago that two single-strand ribonucleic acid (RNA) molecules could spontaneously align themselves to form a double helix.

- Stanford researchers make first direct observation of 3-D molecule folding in real time
02-14-2008 · EurekAlert!
Since the discovery of RNA clumps called "riboswitches," in 2002, scientists have been striving to understand how they work and how they form. Now, researchers at Stanford University are looking closer than ever at how the three-dimensional twists and turns in a riboswitch come together by grabbing it and tugging it straight. By physically pulling on this loopy RNA, they have determined for the first time how a three-dimensional molecular structure folds, step by step.

- Getting on your nerves ... and repairing them
02-15-2007 · EurekAlert!
In a study to be published in the March 2007 issue of the FASEB Journal, scientists from East Carolina University report that a key molecular mechanism, RNA interference (RNAi), plays a role in the regeneration and repair of periphery nerves, which are the nerves located outside of the brain and spinal column. This research may lead to new therapies that manipulate RNAi to treat people with damaged nerves resulting from degenerative disorders and injury.

- Scientists find new genes for Crohn's disease
04-15-2007 · EurekAlert!
A consortium of US and Canadian researchers is reporting in today's online issue of Nature Genetics that they have discovered several more genetic variations that are strongly linked to an increased risk for the disease. The discovery of these Crohn's disease-associated genetic variants has identified several key biological pathways that will be the focus of further research to understand how the debilitating inflammatory process is initiated and maintained in many cases of the disease.

- Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
07-25-2007 · EurekAlert!
Carnegie Mellon University scientists have made an important discovery that helps to explain why HIV enters immune cells with ease. They found that after HIV docks onto a host cell, it dramatically lowers the energy required for a cell membrane to bend, making it easier for the virus to infect immune cells. The finding will provide vital data to conduct future computer simulations of HIV dynamics to help further drug discovery and prevent deadly infections.
