Global beef production: Trends, challenges, and opportunities for sustainable development

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Sustainable livestock systems require managing trade‐offs and synergies across productive, socioeconomic, and environmental dimensions to meet rising global beef demand. We present a biophysical framework to analyze how management‐driven energy allocation is manifested through herd size and total and per‐head beef productivity.

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

Systemic and Local Adiposity in the Bone Marrow Microenvironment Associated With Improved Prognosis in Hodgkin Lymphoma: Imaging and Molecular Analysis

open access: yesInternational Journal of Cancer, Volume 159, Issue 3, Page 782-796, 1 August 2026.
Schematic overview of systemic and bone marrow‐specific adiposity in Hodgkin Lymphoma (HL). Body Mass Index was associated with bone marrow (BM) involvement, relapse, and mortality (1). In contrast, increased yellow marrow density was associated with poorer prognosis (2).

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

open access: yesPest Management Science, Volume 82, Issue 8, Page 7510-7525, August 2026.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Open, flexible and global: What is driving changes in learning environments and what will be the results? An examination of policy and practice in two contrasting countries

open access: yesReview of Education, Volume 14, Issue 2, August 2026.
Abstract The starting point of our analysis is to interrogate the proposal that the move towards innovative learning environments (ILEs), understood as change to both design and practice in schools, represents an important global trend, considering if or how ILEs map onto transnational reforms.

Ground‐Truthed Fiber‐Optic Sensing Reveals Internal Tide Bores Over Madeira's Steep Slope

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We demonstrate the combined utility of distributed acoustic sensing (DAS) and repeat conductivity‐temperature‐depth (CTD) profiling for observing internal tide dynamics over a sloping seafloor. While DAS has been widely proposed as a method to infer ocean temperature variability from seafloor cables, quantitative in situ validation has been ...

Unveiling the procoagulant state in Alzheimer's disease: A novel PET imaging strategy

open access: yesAlzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION A subset of Alzheimer's disease (AD) patients exhibits a procoagulant state that remains undiagnosed despite available treatments. We developed positron emission tomography (PET) strategies to in vivo detect cerebral microthrombi in TgCRND8 mice. METHODS PET was performed with a fibrin‐binding probe (FBP) in TgCRND8 and wild‐type

Climate‐Driven Range Shifts Limit the Role of Non‐Native Trees for Adaptation Processes of European Forests

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Ensemble species distribution model based study indicates a limited role of non native tree species as alternatives to vulnerable native tree species in Europe. ABSTRACT Climate change threatens biodiversity and ecosystem services by reducing the suitability of many native tree species in Europe.
