    Description: normous amounts of potential energy lie buried in marine sediments in the form of reduced carbon compounds. The most familiar form of this vast energy reserve is petroleum, which drives the lion's share of today's energy economy. The next most obvious submarine energy reserve, even more abundant than petroleum, is methane. At deep-sea conditions of low temperature and high pressure, large amounts of this natural gas are found in sub-seafloor reservoirs of frozen methane hydrates [1]. Yet there is another abundant, but less obvious, marine energy reserve: sediment-associated organic carbon, which represents about 2% of the dry weight of marine sediments along continental margins. Is it possible to tap into this vast, dispersed form of submarine energy? If so, how? The answer, in part, is that microbes already have tapped into this large energy reserve. Now, in two papers, one in this issue [2] and the other in a previous issue of Science [3], researchers harness microbially generated power by constructing a fuel cell that can exploit the naturally occurring voltage gradient created by microbial activity in marine sediments.

    Description: Author(s): David T. Limmer, Céline Merlet, Mathieu Salanne, David Chandler, Paul A. Madden, René van Roij, and Benjamin Rotenberg The fluctuations of the charge on an electrode contain information on the microscopic correlations within the adjacent fluid and their effect on the electronic properties of the interface. We investigate these fluctuations using molecular dynamics simulations in a constant-potential ensemble with hi... [Phys. Rev. Lett. 111, 106102] Published Wed Sep 04, 2013

    Notes: Abstract A decision-tree model of an indigenous forest management system centered around shamu (Cunninghamia lanceolata),an important timber species in China, was constructed from extensive interviews with peasants in two villages in Fujian Province, China. From this model additional interviews were conducted to elicit from these peasants their reasons for selecting among decision alternatives. Those reasons that were of an ecological nature were discussed in detail with the peasants to elicit indigenous interpretations of ecological processes in order to test an hypothesis that a strong analogy exists between traditional indigenous and scientific knowledge of ecological processes. Three cases are presented that test this hypothesis. These three cases concern the effect of intercrops on the growth of shamu,the relative merits of seedlings and root collar sprout cuttings for forest regeneration, and the effects of repeated plantings of shamuon soil chemistry. All three cases provide strong support for the research hypothesis and suggest that, even in the absence of a formalized scientific method, humans exercise mental processes typical of scientific thinking. This phenomenon is called proto-science.

    Notes: Abstract This research was designed to test the following hypothesis: Among traditional (nonliterate and minimally literate) people residing in their home environment, traditionally derived knowledge of specific cases of ecological processes can approximate scientifically derived knowledge of those same cases. After locating three minimally literate peasant family lineages in Lijiayang and Linfengkeng villages, Shouning County, Fujian Province, China, not applying science-based systems of agroforest management, a decision-tree model of an indigenous agroforest management system was constructed from extensive interviews. The system was centered around shamu (Cunninghamia lanceolata),an important timber species with a long history of management in China. A major part of the management system is agricultural intercropping with a wide variety of cereal, cash, medicinal, and oil-producing crops. Intercropping is practiced in the initial phases of afforestation; is an integral aspect of site preparation and the tending of the young stand; and contributes to tree establishment, growth, and survival. The cases presented demonstrate that local peasant knowledge of the effects of burning, site preparation, crop selection, crop tending, and intercropping duration on soil quality and the survival and development of shamu is strongly analogous to the knowledge derived through systematic scientific research. This process of deriving scientifically valid ecological knowledge through traditional means is called protoscience.
