Hydrologic simulation models that inform policy decisions are difficult to interpret Posted: 11 Oct 2019 01:53 PM PDT Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with advances in computer technology and software with graphical user interface (GUI). While these technologies make the models more accessible, problems can arise if they are used by inexperienced modelers. |
How preprocessing methods affect the conversion efficiency of biomass energy production Posted: 11 Oct 2019 01:53 PM PDT Research on energy production from biomass usually focuses on the amount of energy generated. But it is also important to consider how much energy goes into the process, a component that is often neglected. A study from the University of Illinois takes a look at the bioconversion efficiency of two products often used as biomass for energy production, miscanthus giganteus and sugarcane bagasse. |
New tool enables Nova Scotia lobster fishery to address impacts of climate change Posted: 11 Oct 2019 12:53 PM PDT Researchers use long-term survey data sets and climate models to help fishing communities plan for a warmer ocean. Researchers have developed a tool that incorporates projected changes in ocean climate onto a geographic fishery management area. Now fishermen, resource managers, and policy-makers can use it to plan for the future sustainability of the lobster fishery in Nova Scotia and Canadian waters of the Gulf of Maine. |
Fast-acting German insecticide lost in the aftermath of WWII Posted: 11 Oct 2019 10:19 AM PDT A new study explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide. |
Six degrees of nuclear separation Posted: 11 Oct 2019 10:19 AM PDT For the first time, scientists have printed 3D parts that pave the way to recycling up to 97 percent of the waste produced by nuclear reactors. |
CO2 emissions cause lost labor productivity Posted: 11 Oct 2019 10:18 AM PDT Extreme high temperatures caused by CO2 emissions could lead to losses in labor productivity. The authors found that every trillion tons of CO2 emitted could cause global GDP losses of about half a percent. They add that we may already be seeing economic losses of as much as 2% of global GDP as a result of what we have already emitted. |
New material captures carbon dioxide and converts it into useful chemicals Posted: 11 Oct 2019 08:22 AM PDT The captured CO2 can be converted into useful organic materials. |
Population aging to create pockets of climate vulnerability in the US Posted: 11 Oct 2019 08:22 AM PDT Population aging projections across the US show a divide between cities and rural areas, which could lead to pockets of vulnerability to climate change. |
Liquid metals the secret ingredients to clean up environment Posted: 11 Oct 2019 06:59 AM PDT Liquid metal catalysts show great promise for capturing carbon and cleaning up pollutants, requiring so little energy they can even be created in the kitchen. |
Physics: An ultrafast glimpse of the photochemistry of the atmosphere Posted: 11 Oct 2019 06:59 AM PDT Researchers have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols. |
Cold temperatures linked to high status Posted: 11 Oct 2019 06:59 AM PDT Researchers have discovered that people associate cold temperatures with luxury items, which is important for companies that are trying to promote products that convey high status. |
Fairy-wrens change breeding habits to cope with climate change Posted: 11 Oct 2019 06:59 AM PDT Warmer temperatures linked to climate change are having a big impact on the breeding habits of one of Australia's most recognisable bird species. |
