CRISPR‐induced knockouts reveal a dual role for the soybean NFR5α gene in symbiotic nitrogen fixation and root hair development

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Nitrogen fixation in soybeans, facilitated by symbiotic interactions with rhizobia, is a cornerstone of sustainable agriculture, reducing reliance on synthetic fertilizers. However, the efficiency of symbiotic nitrogen fixation (SNF) varies due to natural genetic variation in SNF‐related genes.

Galactomyces ferment filtrate upregulates anchoring junctions and stabilizes actin to maintain the Young's modulus of skin cells in vitro

International Journal of Cosmetic Science, Volume 48, Issue 1, Page 16-29, February 2026.
Ageing causes actin cytoskeleton disorganization, a reduction in cellular components associated with the actin cytoskeleton and focal adhesions, and a reduction in skin firmness. Galactomyces ferment filtrate boosts actin stability, increases expression of anchoring junction proteins, including focal adhesions and protects against loss of firmness ...

Antiferromagnetic MnNi tips for spin-polarized scanning probe microscopy

, 2018
Spin-polarized scanning tunneling microscopy (SP-STM) measures tunnel magnetoresistance (TMR) with atomic resolution. While various methods for achieving SP probes have been developed, each is limited with respect to fabrication, performance, and allowed

Model arenes hydrogenation with silica-supported rhodium nanoparticles:The role of the silica grains and of the solvent on catalytic activities [PDF]

, 2009
Silica-supported rhodium-based nanoheterogeneous catalysts were easily prepared by impregnation with a pre-stabilized colloidal suspension. The resulting catalysts contain rhodium nanoparticles well-dispersed in the silica pores with a mean size of 5 nm.

Extremely Long Nanoribbons Comparable to Gecko Foot by Soft‐Template Electropolymerization From Triphenylamine‐Based Monomers

Nano Select, Volume 7, Issue 1, January 2026.
Extremely long nanoribbons are formed by soft‐template electropolymerization in micellar condition, especially with the monomer with the longest conjugation system (N‐m‐Ph‐p‐diPh‐Cb). These surfaces with nanoribbons are extremely hydrophobic (θw = 131.8°) but with extremely strong water adhesion comparable to gecko foot.
