A report published today shows how electrons hop across otherwise electrically insulating areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of electrically conductive 'stepping stones'.
Mexican entrepreneurs designed the first national machine capable of recycling Styrofoam (expanded polystyrene) and transform it into a raw material used in the manufacture of transparent hard plastic.
China, the world's biggest solar market for two years running, is pushing to install more panels at factories, schools and even greenhouses as it seeks to meet its goals under a historic climate agreement with the U.S.
The European Union's flagship Copernicus program ensures operational monitoring of the atmosphere, oceans, and continental surfaces, and will provide reliable, validated information services for a range of environmental and security applications.
Reducing emissions of non-CO2 gases and air pollutants with climate effects would bring health benefits and near-term climate co-benefits - but the impact on long-term climate change might be lower than previously estimated, according to a new study of the potential of air pollution and carbon dioxide mitigation in climate stabilization scenarios.
SciDataCon2014, the International Conference on Data Sharing and Integration for Global Sustainability, was motivated by the conviction that the most significant research challenges - and in particular the pressing issues relating to global sustainability in the face of ongoing natural and human-induced changes to the planetary system - cannot be properly addressed without paying attention to issues relating to equitable access to quality-assured and interoperable datasets and their long-term management and preservation.
A new study performed by a team of international scientists reveals that a complex ecosystem response to iron fertilization in the Southern Ocean might reduce the efficiency of biological carbon pump in transporting carbon dioxide into the deep ocean.
The new method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed, for example, in wireless self-powered sensors and medical implants, where they could ultimately replace batteries.
