Current Protocols, Volume 6, Issue 6, June 2026.Abstract Nicotinamide adenine dinucleotide (NAD+) is an essential metabolite involved in numerous biological processes, functioning both as a redox cofactor in cellular energy metabolism and as a co‐substrate for NAD+‐utilizing enzymes, including sirtuins and poly(ADP‐ribose) polymerases.

Climatic Niche Modelling Reveals Limited Phylogenetic Niche Conservatism in New World Crocodylians
Journal of Biogeography, Volume 53, Issue 6, June 2026.ABSTRACT Aim Phylogenetic niche conservatism, the tendency of closely related species to retain ancestral ecological traits, has gained considerable interest, yet the lack of integration across independent evaluation methods has hindered our understanding of whether niches are conserved or dynamic.

Automorphism groups of P1$\mathbb {P}^1$‐bundles over geometrically ruled surfaces
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We classify the pairs (X,π)$(X,\pi)$, where π:X→S$\pi \colon X\rightarrow S$ is a P1$\mathbb {P}^1$‐bundle over a non‐rational geometrically ruled surface S$S$ and Aut∘(X)$\mathrm{Aut}^\circ (X)$ is relatively maximal, that is, maximal with respect to the inclusion in the group Bir(X/S)$\mathrm{Bir}(X/S)$.

Ion Cyclotron Waves Associated With Ionospheric Outflow at Jupiter
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The mechanism driving ion outflow from Jupiter's auroras remains to be determined. H+ ${\mathrm{H}}^{+}$ outflow has been observed with highly field‐aligned pitch angles consistent with acceleration by high‐altitude electrostatic potential structures.

Piezo-Potential Generation in Capacitive Flexible Sensors Based on GaN Horizontal Wires
Nanomaterials, 2018 We report an example of the realization of a flexible capacitive piezoelectric sensor based on the assembly of horizontal c¯-polar long Gallium nitride (GaN) wires grown by metal organic vapour phase epitaxy (MOVPE) with the Boostream® technique

Aggregate, Volume 7, Issue 5, May 2026.In this work, a tunable luminescent liquid crystal system with clusterization‐triggered emission was constructed. The liquid crystal mesogen B‐Chol formed a thermotropic liquid crystal with clusteroluminescence character. The change of birefringence, the chirality inversion and clusteroluminescence enhancement could be realized by the host‐guest ...
