The Clinical Spectrum and Neurodevelopmental Pathogenesis of KPTN‐Related Disorder in a Mouse Model

open access: yesAnnals of Neurology, Volume 99, Issue 5, Page 1287-1302, May 2026.
Objective Pathogenic variants in Kaptin (KPTN) cause KPTN‐related disorder (KRD). KPTN modulates mTOR signaling activation within the KICSTOR complex in response to cellular amino acid levels. We define the clinical spectrum and investigate the developmental pathogenesis of KRD.

Bypassing Oxidative Addition: Steric Control in Aryl Iodide Activation at Rh(I) Promotes an Open‐Shell Rh(II) Pathway

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Steric hindrance in a bulky PCP pincer complex switches Rh(I) aryl‐iodide activation from the classical two‐electron oxidative addition route to a one‐electron pathway, yielding a paramagnetic RhIII complex and the aryl radical. The latter reacts with benzene to form biphenyl and a Rh(III) hydride.

Board Governance as a Strategic Mechanism: Carbon Risk and Firm Performance

open access: yesCorporate Social Responsibility and Environmental Management, Volume 33, Issue 3, Page 3832-3850, May 2026.
ABSTRACT Carbon emissions are a major contributor to global warming and pose significant threats to the environment. In response to the urgency of climate change, firms are under increasing pressure to adopt policies that enhance environmental performance while reducing carbon risk.

Chloroplast Phylogenomics and Barcode Discovery in Medicinal Stachys Species Reveal Evolutionary Relationships and Adaptive Signatures

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study presents the first complete chloroplast genomes of two medicinally important Stachys species, S. persica and S. germanica. Comparative phylogenomic analyses revealed highly conserved genomes with lineage‐specific variations, identified hypervariable regions as candidate DNA barcodes, and detected signatures of positive selection in the petB ...

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging
