The good donation attempt: A qualitative analysis of donor experience regardless of phlebotomy outcome

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Globally, blood donation rates are declining as demand for blood products grows. Given that having a positive donation experience is key to retention, this analysis explores how aspects of service quality provided by blood collection agencies shape donation experiences.

Investigating the effect of Pb on As determination in soil materials using x‐ray fluorescence spectrometry at high levels of Pb contamination

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract X‐ray fluorescence spectrometry (XRF) is a method of quantifying elements in soil and other media widely used by researchers in many fields. Inaccuracy in XRF can result from spectral interference between Pb and As, two of the most toxic and highly prevalent soil contaminants.

Brain–Behavior Coupling During Cognitive–Postural Dual‐Tasking in Older Adults With Mild Cognitive Impairment: An fNIRS Study

Brain and Behavior, Volume 16, Issue 11, November 2026.
Among 53 older adults, mild cognitive impairment was associated with poorer balance and reduced cortical activation under challenging cognitive‐postural dual tasks. Under eyes‐closed, unstable‐surface conditions, right prefrontal activation showed a stronger association with mediolateral sway in the mild cognitive impairment group than in controls (FDR‐

Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

Advanced Optical Materials, Volume 14, Issue 38, 16 October 2026.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Plasma eMTBR‐tau243 as a disease biomarker across Alzheimer's disease clinical phenotypes

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION The concentration of endogenous tau microtubule‐binding region containing residue‐243 in plasma (eMTBR‐tau243) has been proposed to be a sensitive biomarker of tangle pathology in Alzheimer's disease (AD). We assessed eMTBR‐tau243 and phosphorylated tau217 (p‐tau217) with tau and Aβ‐positron emission tomography (PET) across ...
