Hydrologic simulation models that inform policy decisions are difficult to interpret

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

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

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

A new study explores the chemistry as well as the complicated and alarming history of DFDT, a fast-acting insecticide.

The impact of human-caused noise pollution on birds

Anthropogenic noise pollution (ANP) is a globally invasive phenomenon impacting natural systems, but most research has occurred at local scales with few species. Researchers in this study investigated continental-scale breeding season associations with ANP for 322 bird species to test whether local-scale predictions are consistent at broad spatial extents for an extensive group of North American bird species in the continental United States.

Six degrees of nuclear separation

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

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.

Population aging to create pockets of climate vulnerability in the US

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

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.

New tool visualizes nature's benefits worldwide

The researchers set out to understand where nature contributes the most to people and how many people may be affected by future changes. By 2050, up to 5 billion people could be at higher risk of water pollution, coastal storms and under-pollinated crops.

Sharing data for improved forest protection and monitoring

Although the mapping of aboveground biomass is now possible with satellite remote sensing, these maps still have to be calibrated and validated using on-site data gathered by researchers across the world.

Scientists track wheat aphids and their natural enemies for better pest management in Pakistan

Scientists have studied the distribution and population dynamics of wheat aphids and their natural enemies in Pakistan through seasons and periods of time. This research could be useful to develop better pest management methods and safer, healthier crops in wheat production.
