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,

Traceability, Moral Hazard, and Food Safety [PDF]

open access: yes
Errors in traceability can significantly impact the moral hazard associated with producing safe food. The effect of moral hazard depends on the proportion of unsafe food costs that can be allocated to the responsible producer, which depends on the ...

Spectroscopic Analysis of Hydration Structures in PEG‐ and PMPC‐Containing Hydrogels by Pressure‐Controlled ATR‐IR Combined With Multivariate Curve Resolution

open access: yesSurface and Interface Analysis, Volume 58, Issue 12, Page 1071-1080, December 2026.
ABSTRACT Hydration structures govern the properties and functions of hydrogels, yet selectively measuring hydration water in the presence of abundant bulk water remains analytically challenging. Here we applied pressure‐controlled attenuated total reflection infrared spectroscopy (ATR‐IR) combined with multivariate curve resolution (MCR) analysis, a ...

Consumers' perception of food traceability in Europe [PDF]

open access: yes
Food traceability has become mandatory since 1st January 2005 in the European Union. Traceability of products and activities in the supply chain has become a new factor of competitiveness in agribusiness and is deemed to be an important criterion of ...

Occupational Allergic Contact Dermatitis From Over‐Ear Headphones: Chemical Analysis Reveals Octylisothiazolinone and Other Potential Skin Sensitizers

open access: yesContact Dermatitis, Volume 95, Issue 6, Page 557-565, December 2026.
ABSTRACT Background Over‐ear headphones are a growing source of allergic contact dermatitis (ACD). Identifying well‐known and new culprit sensitizers in such products is challenging because of a lack of labelling and limited cooperation from manufacturers.

Transformational Faulting: The Case of Quartz‐Coesite

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Transformational faulting in olivine has been widely invoked as a possible triggering mechanism for deep‐focus earthquakes, yet its dynamics remain debated. It is unclear whether it requires the combined effects of heat release, volume change and mechanical strength contrast, or whether it can be triggered by any one of these alone.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

open access: yesPolymer Composites, Volume 47, Issue 21, Page 19085-19107, 10 November 2026.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices

open access: yesLaser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.
