‘Wetting’ the Appetite of a Battery for Renewable Energy Storage

New liquid alloy electrode improves sodium-beta battery performance Sun, wind and other renewable energy sources could make up a larger portion of the electricity America consumes if better batteries could be built to store the intermittent energy for cloudy, windless days. Now a new material could allow more utilities to store large amounts of renewable […]

Climate Change: A Plan to Share the Carbon Budget Burden

Climate change is an issue of urgent international importance, but for 20 years, the international community has been unable to agree on a coordinated way to reduce greenhouse gas emissions. In a “Perspective” piece published in the June issue of Nature Climate Change, J. Timmons Roberts, the Ittleson Professor of Environmental Studies and Sociology, proposes […]

In grasslands remade by humans animals may protect biodiversity

Grazers let in the light, rescue imperiled plants, worldwide study shows A comparative study of grasslands on six continents suggests there may be a way to counteract the human-made overdose of fertilizer that threatens to permanently alter the biodiversity of the world’s native prairies. The solution is one that nature devised: let grazing animals crop […]

Methane hydrates and global warming

Dissolution of hydrates off Svalbard caused by natural processes Methane hydrates are fragile. At the sea floor the ice-like solid fuel composed of water and methane is only stable at high pressure and low temperature. In some areas, for instance in the North Atlantic off the coast of Svalbard, scientists have detected gas flares regularly. […]

Climate Change Puts 40 Percent More People at Risk of Absolute Water Scarcity: Study

Water scarcity impacts people’s lives in many countries already today. Future population growth will increase the demand for freshwater even further. Yet in addition to this, on the supply side, water resources will be affected by projected changes in rainfall and evaporation. Climate change due to unabated greenhouse-gas emissions within our century is likely to […]

Recycled plastic proves effective in killing drug-resistant fungi

New uses for recycled plastic — PET in this case — are beginning to emerge. See the following press announcement. Researchers at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) and California’s IBM Research – Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. […]

High bat mortality from wind turbines

Renewable energy solutions from wind turbines provide promise worldwide that longterm sustainable energy solutions will form a foundation for future energy capture and distribution strategies. Such solutions do no not always come about without paying a significant price, however. This report on wind turbines and massive bat deaths is disturbing. Clean energy cure needs to […]

Understanding soil nitrogen management using synchrotron technology

How different fertilizers affect soil organic matter and what that means for crops As food security becomes an increasingly important global issue, scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation. Increasing the organic matter in soils is key to growing crops […]

Next-Generation Antireflection Coatings Could Improve Solar Photovoltaic Cell Efficiency

Materials boasting a “tunable” refractive index have been developed within the past few years, and they show tremendous potential for photovoltaic applications. Professor E. Fred Schubert, of Rensselaer Polytechnic Institute’s Department of Electrical, Computer, and Systems Engineering, is investigating ways to exploit this newly gained controllability and will present his findings at the upcoming AVS 59th International Symposium and Exhibition, held Oct. 28 – Nov. 2, in Tampa, Fla.
