Subduction Initiation Volcanism Leading to Development of the Talkeetna Arc, Lower Shuyak Formation, Kodiak Archipelago, Alaska

open access: yesTectonics, Volume 45, Issue 4, April 2026.
Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of

A Qualitative Review of Clinical Decision‐Making Using [99mTc]Tc‐Mercaptoacetyltriglycine Renal Scintigraphy in Patients With Malignant Ureteral Obstruction

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue 1, Page 106-114, March 2026.
This case series evaluated the clinical utility of [99mTc]Tc‐MAG3 renal scintigraphy in managing malignant ureteral obstruction (MUO). Renal scintigraphy‐guided decision‐making allowed safe conservative management in selected patients, particularly those with a non‐functional excretion pattern, and helped avoid unnecessary urinary drainage.

Rover‐Induced Mineral Transformations: Extent of the Effect for the Mars Science Laboratory and Opportunities for Future Landed Mission

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract X‐ray amorphous sulfate hydrates are a substantial component (up to 23 wt%) of the sedimentary rocks and sands analyzed to date by the Mars Science Laboratory Curiosity rover at Gale crater. Recently, the CheMin X‐ray diffractometer observed the amorphization of the crystalline sulfate starkeyite (MgSO4 · 4H2O) upon exposure to the dry and ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

open access: yesGlobal Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed

Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

open access: yesTectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...
