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

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.
