Optimal Control‐Based RF Pulses Versus Classical Motion‐Encoding Strategies for In Vivo Hepatic MR Elastography Across Multiple Excitation Frequencies in Mice: Reproducibility Assessment

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Optimal control (OC)–based motion encoding doubles SNR in vivo in murine hepatic MRE by eliminating motion‐encoding gradients and enabling shorter echo times. Quantitative liver stiffness measurements remain consistent with conventional MEG‐MRE across multiple excitation frequencies, supporting longitudinal studies and clinical translation ...

Two distinct alcohol dehydrogenase classes mediate bacterial 2‐hydroxyethylphosphonate catabolism

open access: yesProtein Science, Volume 35, Issue 10, October 2026.
Abstract Phosphonates are molecules containing a direct carbon‐phosphorus bond. In nature, these compounds are produced by a variety of organisms, and many environmental microbes are able to degrade specific phosphonates and feed on them. This work focuses on 2‐hydroxyethylphosphonate (HEP)—a natural compound that is found frequently in the environment,

When Bigger Is not Better: Corolla Length Increases Nectar Robbing in Aloe secundiflora Engl. (Asphodelaceae)

open access: yesAfrican Journal of Ecology, Volume 64, Issue 7, October 2026.
ABSTRACT Nectar robbing is a widespread but unevenly documented component of plant–pollinator interactions, and quantitative assessments from African savanna systems remain limited. Based on a short field survey conducted over two consecutive days, this study quantified the frequency and reproductive consequences of nectar robbing in a population of ...

Can Machine Learning Reduce Unnecessary Surgeries? A Retrospective Analysis Using Threshold Optimization to Prevent Negative Appendectomies in Adults

open access: yesAnnals of Gastroenterological Surgery, Volume 10, Issue 5, Page 1631-1645, September 2026.
Threshold‐optimized machine learning models using routine clinical and laboratory data in 623 adults undergoing appendectomy. Logistic regression (AUC = 0.765) and random forest (AUC = 0.785) were the best‐performing models for appendicitis detection and complicated appendicitis prediction, respectively.
