Sustainable seafood initiatives, including certification and ecolabeling and awareness schemes, could be extended to more effectively cover inland, freshwater fisheries, according to researchers writing in the November issue of BioScience.
The world's growing dependence on fish protein and the imperiled state of many freshwater fisheries argues for such efforts, the authors conclude, although because freshwater fisheries tend to be smaller and are more concentrated in developing countries than marine and coastal fisheries, the efforts would have to be modified substantially to target the different consumers.
The article's authors, Steven Cooke of Carleton University and two colleagues, initially set out to assess the scientific literature on ecolabeling and awareness schemes as they related to freshwater species, but soon determined there were very few such studies.
Although freshwater species and those (such as salmon) that live in freshwater during part of their life cycle are included in lists intended for guide consumers on sustainable diet choices, they constitute a small minority, according to a survey of 10 certification and labeling schemes. This imbalance could lead to a public misperception that freshwater species are generally less at risk than marine species, Cooke and his colleagues argue.
Grassroots schemes, rather than multimedia marketing-oriented certification schemes, are the most promising approach to increasing awareness of the threats to freshwater species and what choices consumers can make to reduce these, the authors say, because many freshwater fisheries are artisanal.
BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
