Does more need to be done to support and encourage young scientists to devote themselves to inventing new theoretical concepts and models? Correspondence Top Due credit for Maxwell-Bloch equations   p207 Brian McNeil doi:10.1038/nphoton.2015.44 The true status of solar cell technology   pp207 - 208 K. D. G. Imalka Jayawardena, Lynn J. Rozanski, Christopher A. Mills and S. Ravi P. Silva doi:10.1038/nphoton.2015.45 Books and Arts Top New titles at a glance   p209 Applications of Nanoscience in Photomedicine Edited by Michael R. Hamblin and Pinar Avci doi:10.1038/nphoton.2015.55 Research Highlights Top Lasers: CEP stable laser | Metamaterials: Anomalous reflection | Plasmonics: Recipe for success | Optical fibres: Silicon-silica integration | Slow light: On-chip pulse compression News and Views Top Organic emitters: Light-emitting fabrics   pp211 - 212 Enrique Ortí and Henk J. Bolink doi:10.1038/nphoton.2015.53 Light-emitting fibres that suit integration with textiles are prepared by dip-coating a steel wire with an electroluminescent material and then cleverly wrapping the structure with a carbon nanotube sheet that functions as a transparent electrode.

Mid-infrared photonics: Spiral superluminescent emitter   p212 Noriaki Horiuchi doi:10.1038/nphoton.2015.52 Nonlinear optics: Anti-diffraction of light   pp213 - 214 Hayk Harutyunyan doi:10.1038/nphoton.2015.39 Using an electro-optic effect, submicrometre-sized beams have been shown to exhibit non-paraxial propagation over 1,000 Rayleigh lengths. The discovery does not require inhomogeneous or lossy media like plasmon waveguiding. See also: Letter by DelRe et al. Metamaterials: Naturally hyperbolic   pp214 - 216 Evgenii E. Narimanov and Alexander V. Kildishev doi:10.1038/nphoton.2015.56 Natural hyperbolic materials hold the key to unlocking the full potential of hyperbolic media in nanophotonics. Until now no such materials were available for visible light but recent work finally brings down this roadblock. Photoacoustic imaging: Cells make themselves heard   pp216 - 218 Srirang Manohar, Aart van Apeldoorn and Wiendelt Steenbergen doi:10.1038/nphoton.2015.46 A photoacoustic imaging scheme that uses genetically altered cells that express an absorbing pigment can monitor in vivo growth of cells and tumour development.
