Sequestration on shaky ground

Study finds a natural impediment to the long-term sequestration of carbon dioxide. CAMBRIDGE, Mass. -- Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth’s…

This sequence of graphs illustrates the application of the researchers' technique to a real-world computer vision problem. The solution to each successive problem (red balls) is used to initialize (green arrows) the search for a solution to the next.
