This presentation pertaining to a CO2 sponge is one of some 12,000 at the 248th National Meeting & Exposition of the American Chemical Society (ACS). If any part of this comes to a greater reality in mitigating climate change, this one particularly piques our interest. Read this press announcement from AAAS EurekAlert. A sponge-like plastic […]

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 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 […]
This call for smaller and more manageable electricity grids makes a tremendous amount of sense. David Newman at the University of Alaska provides a good case for his point of view. Read the following press announcement, look at the supporting graphics, and see what you think. Is the power grid too big? Right-sizing the grid […]
Agroforestry, combined with land and water management practices that increase agricultural productivity, can save watersheds from degradation.
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 […]
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. […]
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 […]
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. […]
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 […]
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 […]
Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
When there is little water available for plants to grow, their roots form alliances with soil microbes that can promote plant growth even under water-limiting conditions, according to research published Oct. 31 by Daniele Daffonchio and colleagues from the University of Milan, Italy in the open access journal PLOS ONE.
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.
Influencing sustainable behavior is an ongoing challenge in today’s world. Hotels often ask consumers to “do their part” for the environment by reusing towels, but this approach has limited success. Appeals to adhere to social norms (i.e., informing guests that the majority of guests in a hotel reuse their towels) have been shown to be more effective, yet leave an estimated 50% of hotel patrons unresponsive.
