Two new porcelain crab species discovered

Two new symbiotic porcelain crab species have been described. One of them, from the South China Sea of Vietnam, inhabits the compact tube-like shelters built by the polychaete worm with other organisms. The other inhabits the intertidal vermetid snail formations in the Colombian Caribbean.

Inside the fuel cell: Imaging method promises industrial insight

Hydrogen-containing substances are important for many industries, but scientists have struggled to obtain detailed images to understand the element's behavior. Researchers now demonstrate the quantification of hydrogen for different states of water -- i.e., liquid, frozen and supercooled -- for applications to eco-friendly fuel cells.

I'm shouting because the journal is shouting:

Marine Resource Economics is now accepting submissions for a new section of the journal titled Case Studies, which is intended to provide an outlet for rigorous, theoretically grounded analyses of the governance of individual fisheries and/or aquaculture systems. The new section will be edited by Tracy Yandle of Emory University, and the editors expect the first Case Study to be published in the forthcoming volume of the journal.

“Case studies play a valuable role in the development of our understanding of effective marine resource governance, yet they are underrepresented in the economics literature. This new section presents a unique opportunity for researchers to apply an economic perspective to rigorous case studies—whether comparative case studies, or single case studies focused at a range of scales," said section editor Tracy Yandle. "I look forward to continuing the strong intellectual tradition of Marine  Resource Economics, while expanding its coverage to a broader range of settings and research methods.”

The Case Studies section joins four sections currently published in Marine Resource Economics: Articles, Perspectives, Systematic Reviews, and Book Reviews. Its published pieces will provide description and analysis of a particular regionally defined fishery, aquaculture system, marine resource, or comparisons of two or more cases, with an emphasis on an economic analytical perspective and focus on historic and/or current issues of marine or coastal zone policy and governance.

"I'm very excited for the potential of this new section to expand the reach of the journal to a wider range of scholars and resource management practitioners," said Joshua K. Abbott, Marine Resource Economics editor.

The editors encourage submissions focusing on small-scale fisheries and aquaculture in developing nations. Case studies drawing upon quantitative evidence are preferred, though qualitative analyses are also encouraged—particularly in data-poor settings. All submissions to the Case Studies section are subject to a single-blind peer review process. For more information, please review Marine Resource Economics Instructions for Authors webpage.

This is sure to be the home for many studies that haven't been able to find one in the past. 


Rare 'itinerant breeding' behavior revealed in California bird

Only two bird species have ever been shown to undertake what scientists call 'itinerant breeding': nesting in one area, migrating to another region, and nesting again there within the same year, to take advantage of shifting food resources. However, new research provides strong evidence of this rare behavior in a third bird -- the Phainopepla, a unique bird found in the southwestern US and the northernmost member of an otherwise tropical family.

Cheaper catalyst can generate hydrogen in a commercial device

Researchers have shown for the first time that a cheap catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial electrolyzer -- a step toward clean, large-scale hydrogen production for fuel, fertilizer and industry.

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.

New material captures carbon dioxide and converts it into useful chemicals

The captured CO2 can be converted into useful organic materials.

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.

Physics: An ultrafast glimpse of the photochemistry of the atmosphere

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

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

Warmer temperatures linked to climate change are having a big impact on the breeding habits of one of Australia's most recognisable bird species.

Water + air + electricity = hydrogen peroxide

A reactor produces pure hydrogen peroxide solutions from water, air and energy.

Scientists 'must be allowed to cry' about destruction of nature

Scientists witnessing the destruction of the natural world must be supported and 'allowed to cry,' researchers say.
