Rehydrate -- your RNA needs it

...hing similar had been seen in protein enzymes, but never before in RNA enzymes. The earlier finding, published in PNAS two years ago, suggested that information about changes in distant parts of the ribozyme travels through some sort of network to the core of the molecule, where chemical reactions take ...

Montreal researchers identify defects of immune cells

Now, they become designated targets for the development of novel treatments not only for candidiasis but other mucosal infections."

Johns hopkins researchers find link between cell's energy use and genome health

...enetics at Hopkins and author of the study. "We've never seen anything that can turn off that many genes in a cell at once." The unexpected finding linking both gene usage and energy management machinery is "like finding out that an enzyme that breaks down food in the stomach also helps you remember tele...

"We use SAM with bariatric patients ?individuals who are remarkably overweight," said Mark Castleberry, Director of Rehabil...

Adult stem cells are touchy-feely, need environmental clues

... environment might limit the fate of stem cells, I never really thought that it would be sufficient to direct cell fate," said Lee Sweeney, a coauthor of the study and chairman of Physiology in Penn's School of Medicine. "When I saw Adam's first images, I was stunned to see that the physical environment a...

How plants avoid feeling the burn

...blem, Fisher had to attempt an experiment that had never been done before for any biomolecule: to control the charge of the biomolecule while measuring its ability to hold a current. By holding a carotenoid under potential control, Fisher could control whether the biomolecule was in a neutral state or in...

First human study confirms that immune cells can be a primary cause of bone loss in gum disease

...ated presence of B and T lymphocytes. Since it has never been reported that any bacteria per se invade and resorb bone independent of osteoclast activation, RANKL expression by T cells and B cells proves to be one of the major stimuli of osteoclast precursor cells and, hence, bone loss through periodontal ...

Newly identified protein complex sheds light on axon growth mechanism

...erised UNC-69, a previously known protein that had never been characterised. By studying mutants lacking unc-69 they show that the protein is widely expressed in the C.elegans nervous system and is required for normal axon development. Hengartner and colleagues then show that UNC-69 physically interacts w...

A more powerful and efficient engine for rice: the C3-C4 challenge

It's going to be an enormously complex and difficult challenge, but we think that with all the new knowledge we have about the rice plant ...

Malaria, potato famine pathogen share surprising trait

Kamoun says not to worry ?there's no chance that the potato pathogen will jump to humans, nor is it likely that the malaria parasite will start infecting plants. However, he said it's fe...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

In a technical tour de force, Salk scientists take a global view of the epigenome

Almost a third of Arabidopsis' ~ 26,000 genes were methylated in some manner, and where they were methylated determined the effect. As in mammals, methylation in regulatory regions next to ...

New human retrovirus originated in mice

...tic as to what might be found," he said. "We would never have looked for this class of virus if it wasn't for the virus chip." Importantly, the researchers found that prostate cancers in which both copies of the RNASEL gene were crippled by mutation showed much more frequent XMRV infection than did those ...
