Potential for enhanced sequestration of carbon in soils supports evaluations
...'s team, agriculturally based options for reducing net greenhouse gas emissions by increasing sequestration of carbon in soils "should be evaluated to see how competitive they are in comparison with a variety of other options," such as flue-gas capture to reduce emissions or remove carbon dioxide already...Molecular motor implicated in tissue remodeling
... that MMP-1 moves along a collagen filament with a net unidirectional motion. One-way motion indicates that energy is being utilized, so the team looked for an energy source.

... Cascades south of Mount Rainier. They used a fine net to capture individual Townsend's, hermit and hybrid warblers. All the captures came between 7 a.m. and 1 p.m. to minimize the effect on their measurements of hormone level fluctuations throughout the day.
