[1] Silver hake fish follow the Gulf Stream
DOI: 10.1038/ncomms1420

The northward shift in the distribution of the Silver hake, observed over the past 40 years, can be linked to the path of the Gulf Stream, shows a study published in Nature Communications this week. This suggests that the occurrence of this commercially important fish could be forecast on decadal scales on the northeast coast of the US using the more northerly position of the Gulf Stream predicted by climate models.

Janet Nye and colleagues present an example of how the spatial distribution of a species shifts in response to changing climate conditions, such as temperature. Large-scale atmospheric and oceanic changes in the North Atlantic vary the bottom water temperatures on the shelf and the position of the Gulf Stream, which the adult Silver hake respond to.

[2] Grainy superconductivity
DOI: 10.1038/ncomms1419

The grain boundaries of iron pnictide superconductors have advantages over those of more commonly used cuprate superconductors reports a paper in Nature Communications this week. Iron pnictides have been studied extensively, and many of their advantages over cuprates have already been determined. But the additional information provided by this study could aid the development of high critical temperature superconductors that could be used to produce ‘ideal’ electric power lines with zero power consumption.

The misalignment of crystal grain boundaries, which deteriorates current densities, has previously been considered major problem in the development of high critical temperature superconductors. Hideo Hosono and co-workers investigate transport properties through well-defined bicrystal grain boundaries with different misorientation angles. They find that the current density in iron pnictides is tolerant to higher misorientation angles than in cuprates.

[3] And finally…Selecting the best sounding mate
DOI: 10.1038/ncomms1417

Like humans, female túngara frogs are able to group similar auditory signals in order to locate the correct source of the sound, finds a study in Nature Communications this week. They use this ability to help locate a mate in the cacophony of mating calls in the breeding groups on the rain forest floor.

The male túngara frogs sing in complex aggregate patterns of ‘chucks’ and ‘whines’. This makes it a challenge for the female frog to assign the calls to the correct male in the presence of multiple auditory sources. Hamilton Farris and Michael Ryan show that the females group sounds with the smallest relative difference in call parameters, an approach often applied by humans.
