Neuro-ophthalmic complications of tuberculosis and its treatment: a systematic review and meta-analysis

open access: yesFrontiers in Ophthalmology
IntroductionTuberculosis (TB) and its treatment have been associated with significant neuro-ophthalmic morbidity; however, the magnitude and determinants of these complications remain incompletely characterized.

Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

The Case for Prebiotic Chemistry During the Hadean Eon

open access: yes, 2019
Geochemists disagree whether or not prebiotic chemistry has existed already during the Hadean Eon and whether the then terrestrial atmosphere has been strongly or weakly reduced.

Stratigraphic Partitioning of Evaporites Through the Clay‐Sulfate Transition in Gale Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Changing surface conditions on Mars during the Hesperian eon (∼3.6–3.0 billion years ago) produced widespread stratal sequences transitioning from clay to sulfate‐bearing according to orbital data. Using data collected in situ at Gale crater by the Curiosity rover, we examined both the sedimentology and geochemistry of a 210‐m‐thick succession

The three‐step test in international copyright—a global framework for generative AI training

open access: yesAmerican Business Law Journal, Volume 63, Issue 3, Page 265-298, Fall 2026.
Abstract The training of generative artificial intelligence (genAI) models involves the processing of large datasets, which often include copyrighted materials, thereby raising questions of copyright infringement. These questions tend to center on whether such use constitutes fair use or falls under text and data mining (TDM) exceptions.

Towards Fully AI-Driven Converged Optical Burst Switching and Elastic Optical Networks for Autonomous QoS-Aware IoT Backhaul in 6G and Beyond

open access: yesNetwork
The convergence of optical burst switching (OBS) and elastic optical networks (EON) offers a promising pathway for 6G IoT backhaul. However, existing solutions treat OBS and EON separately and rely on heuristic resource allocation that fails to meet ...

Oxygenaging: A Physiological Framework for Geroscience

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Mechanisms of aging disrupt oxygen homeostasis through three converging processes: oxygen‐cascade impairment, microvascular dysfunction, and molecular maladaptation. “Oxygenaging” integrates these domains to explain how declining oxygen delivery and utilization drive mitochondrial instability and amplify the effect of the hallmarks of aging.
