Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Mutation in RNF170 Causes Unsteady Gait with Hypertrophic Olivary Degeneration

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration resulting from disruption of the Guillain–Mollaret triangle, typically presenting with palatal tremor, ataxia, and nystagmus. Mutations in the Ring Finger Protein 170 (RNF170) gene have been associated with autosomal dominant sensory ataxia.

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...
