New Geometric Shape Used by Nature to Pack Cells Efficiently

a) Scheme representing planar columnar/cubic monolayer epithelia. Cells are simplified as prisms. b) Scheme illustrating a fold in a columnar/cubic monolayer epithelium. Cells adopt the called "bottle 23 shape" that would be simplified as frusta. c) Mathematical model for an epithelial tube. d) Modelling clay figures illustrating two scutoids participating in a transition and two schemes for scutoids solids. Scutoids are characterized by having at least a vertex in a different plane to the two bases and present curved surfaces. e) A dorsal view of a Protaetia speciose beetle of the Cetoniidae family. The white lines highlight the resemblance of its scutum, scutellum and wings with the shape of the scutoids. Illustration from Dr. Nicolas Gompel, with permission. f) Three-dimensional reconstruction of the cells forming a tube. The four-cell motif (green, yellow, blue and red cells) shows an apico-basal cell intercalation. g) Detail of the apico-basal transition, showing how the blue and yellow cells contact in the apical part, but not in the basal part.

Europe Thrives on Renewables Despite Unpredictable Weather

This graphical abstract shows the impact of long-term weather variability on the operation of the European power system and how this scales with uptake of wind and solar power out to 2030. We find that ambitious decarbonization leads to much greater influence of long-term weather patterns, with a 5-fold increase in operational variability by 2030. Several relevant metrics can be reasonably approximated by linear functions of variable renewable penetration, providing a shortcut for estimating the impacts of intermittency.

Researchers in Ireland, Switzerland, and the United Kingdom have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. Using 30 years of meteorological data, the scientists have examined and further modelled the impact of renewable energy on the electricity sector

Creating Material to Miniaturize Telecommunication Devices

Modern communication systems often employ optical fibers to carry signals across or between devices, combining more than one function into a single circuit. However, signal transmission requires long optical fibers, which makes miniaturizing the device difficult. Instead of long optical fibers, scientists have started testing planar waveguides. In the Journal of Applied Physics, investigators report on a laser-assisted study of a type of glass that shows promise as a material for broadband planar waveguide amplifiers.
