Scientists explore genome of methane-breathing microbe
...uch as ruminants and landfills. The PLoS Biology study
found that M. capsulatus has multiple pathways for different stages in the oxidation of methane. They also found genes that suggest metabolic flexibility, including the microbe's likely ability to grow on sugars, to oxidize sulfur, and to live in red...
Key stimulator of colorectal cancer identified
A new research study
identifies a molecule that promotes one of the most deadly cancers in humans and reveals the molecular mechanisms underlying the protective effects of nonsteroidal anti-inflammatory drugs (NSAIDS) against the disease. The research, published in the S...

Prion propagation: Avoiding the toxic oligomer
... to plaque. Using the yeast prion protein Sup35 to study
how amyloids form, Jonathan Weissman and colleagues show, surprisingly, that amyloid plaque formation can occur in the absence of the putative toxic oligomers. In yeast, the Sup35 protein forms self-replicating aggregations reminiscent of a...

...significantly in the last three decades," explains study
author Dr. Tom Curran from St. Jude Children's Research Hospital in Memphis, Tennessee. "This is partly due to the absence of adequate model systems for testing novel therapies." Dr. Curran and colleagues used a mouse model of medulloblastoma that th...
