Impact of Quantum Gravity on the UV Sensitivity of Extremal Black Holes

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT Recent work has revealed that extremal Kerr black holes may exhibit a sensitivity to higher‐derivative corrections to Einstein's equations, displaying singularities in the tidal forces at the horizon. However, in a purely gravitational context, this “ultraviolet sensitivity” translates into a strong dependence on the Wilson coefficients in the

Principled Fourier Neural Operators for High‐Resolution Regional Ocean Modeling

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Reliable and computationally efficient ocean state forecasts are essential for climate resilience, maritime safety, and science‐to‐decision applications. Growing demand has stimulated interest in machine learning approaches as scalable complements to traditional numerical models.

One Single Session to Sleep Them All? The Potential of Single‐Session Interventions for Insomnia

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Poor sleep and insomnia are pervasive public health concerns, with insomnia ranking as the second most prevalent mental health disorder in the general population. Moreover, insomnia is a significant predictor of subsequent depression and is frequently co‐occurring with other psychological difficulties.

The Effects of Daridorexant on Patients With Comorbid Insomnia Disorder and Untreated Mild Obstructive Sleep Apnoea: A Post Hoc Subgroup Analysis of a Phase 3, Randomised Clinical Trial

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Daridorexant, a dual orexin receptor antagonist, is approved for the treatment of insomnia disorder in adults. Approximately 30%–35% of patients with insomnia disorder also have obstructive sleep apnoea (OSA) of any severity. It is unclear whether sleep medications provide safe and effective treatment for insomnia in these patients.

Sleep in Functional Motor Disorders: A Case–Control Polysomnographic Study

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Sleep problems are frequent in functional motor disorders (FMDs). Surprisingly, objective correlates of impaired sleep and its relationship to other comorbidities have been understudied, and no polysomnographic study is available. We aimed to map the polysomnographic parameters in the context of self‐reported sleep and mood symptoms and search

Digital App Based Cognitive Behaviour Therapy CBT‐I Course Improving Insomnia and Sleep Hygiene: A Randomised Controlled Trial

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Problems with initiating and maintaining sleep are among the most common health complaints, with prevalence rates exceeding 50% depending on the survey. Preventing the progression to chronic insomnia may reduce public healthcare costs and prevent secondary illnesses.
