- Distinct traits between mainland and island populations provide an excellent opportunity to study the evolution and genetic basis of these traits. In this issue, Walsh et al. unraveled the evolution of black plumage color that arose independently in two island populations of the white-winged fairywren. They also described the first steps in understanding the genetic underpinnings of this trait.

Konferensbidrag (refereegranskat)abstract
- Since IEC 61499 has reached the state of an international standard and a substantial body of research results exists the question of the authors as main intention for this paper was: Do the models of IEC 61499 solve all problems when thinking of usability and interoperability in heterogeneous system environments? The main problems discussed within the paper concern to the execution model defined for basic function blocks and the scheduling of events within function block networks

Tidskriftsartikel (refereegranskat)abstract
- Realizing visionary concepts of integrated photonic circuits, nanospectroscopy, and nanosensing will tremendously benefit from dynamically tunable coherent light sources with lateral dimensions on the subwavelength scale. Therefore, we demonstrate an individual nanowire laser based device which can be gradually tuned by reversible length changes of the nanowire such that uniaxial tensile stress is applied to the respective semiconductor gain material. By straining the device, the spontaneous excitonic emission of the nanowire shifts to lower energies caused by the bandgap reduction of the semiconductor. Moreover, the optical gain spectrum of the nanolaser can be precisely strain-tuned in the high excitation regime. The tuning of the emission does not affect the laser threshold of the device, which is very beneficial for practical applications. The applied length change furthermore adjusts the laser resonances inducing a redshift of the longitudinal modes. Thus, this concept of gradually and dynamically tunable nanolasers enables controlling and modulating the coherent emission on the nanoscale without changing macroscopic ambient conditions. This concept holds therefore huge impact on nanophotonic switches and photonic circuit technology.
