TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology

open access: yesRapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Calcium Isotopic Composition in Reindeer (Rangifer tarandus) Bones and Tooth Enamel: A Scalable Tool to Quantify Nursing Frequency in Past and Modern Populations?

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.
ABSTRACT Rationale Populations of North American caribou and Eurasian reindeer (Rangifer tarandus sspp.), essential for Arctic ecosystems and human communities, are experiencing unprecedented declines due to climate change and anthropogenic pressures. While understanding their historical resilience and demographic dynamics is critical for conservation,

Detection and Excretion Profile of Retatrutide in Human Plasma and Urine by LC‐HRMS: Implications for Antidoping Analysis

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 23, 15 December 2026.
ABSTRACT Rationale Retatrutide (LY3437943) is a novel long‐acting triple incretin receptor agonist that targets the glucagon‐like peptide‐1 receptor (GLP‐1R), glucose‐dependent insulinotropic polypeptide receptor (GIPR), and glucagon receptor (GCGR). Its pronounced effects on body composition and metabolic health, combined with increasing off‐label use

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

From Prevention to Healthy Longevity: Evaluating the Multi‐Systemic Effects of Physical Activity and Lifestyle Behaviours in Women

open access: yesReproductive, Female and Child Health, Volume 5, Issue 4, December 2026.
ABSTRACT Purpose Despite spending more on healthcare than any other high‐income nation, the United States faces comparatively poor life expectancy outcomes, primarily due to non‐compliance with preventable and modifiable lifestyle behaviours. This review evaluates the multi‐systemic benefits of physical activity, exercise, diet, weight management and ...

English Learning, Coloniality, and Racism: Practice and Discourse of Study Abroad in the Philippines in the Japanese ELT Market

open access: yesTESOL Journal, Volume 17, Issue 4, December 2026.
ABSTRACT Although the Philippines is gaining growing recognition as an effective site for English learning, especially among Japanese and Korean students, critical attention must be paid to the instrumentalization of Filipino instructors and the country, and the racialized discourse and practice.

Tracing the Untraceable: A Review and Discussion on the Forensic Attribution of 3D‐Printed Firearms

open access: yesWIREs Forensic Science, Volume 8, Issue 4, December 2026.
3D‐printed firearms are rapidly evolving and challenge traditional forensic identification. This review highlights emerging attribution methods, from deposition striae and base‐plate marks to polymer and GSR residual traces, firing marks, and quantitative imaging, identifying the research needed to support robust forensic attribution interpretation and

Exploratory Measurements of Singly Substituted and Clumped Isotopologues in Iodate Using Electrospray Ionization Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 22, 30 November 2026.
ABSTRACT Rationale Clumped isotope geochemistry can reveal the temperatures and chemical pathways at which molecules form, but it remains unexplored for most inorganic systems. Iodate (IO3−) is central to ocean and atmospheric iodine cycling and to tracking radioactive iodine from nuclear activity.

Mass Spectrometry for Semiquantitative Analysis of Thermal Decomposition: A Methodological Case Study on the Pyrolysis of a (CH3)SiO1.5 Hybrid Gel

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 21, 15 November 2026.
ABSTRACT Rationale The thermal decomposition of (CH3)SiO1.5 gels has been systematically investigated by TG‐MS, revealing a complex temperature‐dependent evolution of gaseous species. This work demonstrates that the TG‐MS analysis, coupled with rigorous data processing, allows to set up an insightful methodology to evolve from a qualitative monitoring ...

Stability and Change in Life Narratives by Elderly Adults With Alzheimer's Dementia, Depression, and Healthy Controls

open access: yesApplied Cognitive Psychology, Volume 40, Issue 6, November/December 2026.
ABSTRACT Autobiographical memory is affected by Alzheimer's dementia and depression in old age. We suggest that cognitive decline in Alzheimer's dementia affects both the life narrative construction of personal stability and change, whereas the decline of vitality in depression affects only the construction of change, but not stability of personal ...
