The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

Mammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

New Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Interleukin‐6 as a Key Biomarker in Facioscapulohumeral Dystrophy: Evidence From Longitudinal Analyses

Annals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 310-323, February 2026.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is a progressive neuromuscular disorder with no approved treatments. Identifying reliable biomarkers is critical to monitor disease severity, activity, and progression. Interleukin‐6 (IL‐6) has been proposed as a candidate biomarker, but longitudinal validation is limited ...

Small is the New Large: Demonstration of how Microanalyses Elucidate Large‐Scale CO2 Uptake Through Mineralization

Advanced Sustainable Systems, Volume 10, Issue 2, February 2026.
Imaging techniques like X‐ray microcomputed tomography and electron microscopy are integrated to understand the CO2 mineralization process at the pore‐scale. These techniques are used to characterise the reaction progression in basalt. They increase the reliability of reactive transport modeling and consequently improve the CO2 storage capacity ...

Farnesyl Diphosphate Synthase Promotes Proliferation of Hepatocellular Carcinoma Cells by Interacting With Glucose‐6‐Phosphate Dehydrogenase

Cancer Medicine, Volume 15, Issue 2, February 2026.
ABSTRACT Background Hepatocellular carcinoma (HCC) is a highly aggressive malignancy characterized by metabolic reprogramming that supports tumour growth and survival. This study identifies farnesyl diphosphate synthase (FDPs), a key enzyme in the mevalonate pathway, as a critical regulator of HCC proliferation and apoptosis.

DNTTIP1 drives leukaemogenesis through MiDAC‐mediated epigenetic silencing of BMF

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
DNTTIP1 cooperates with SP1 to recruit HDAC1/2, leading to BMF silencing and reduced competitive binding of BMF to BCL2.This suppresses autophagy and apoptosis, promoting leukaemic cell survival. Targeting the DNTTIP1‐HDAC1/2‐BMF axis reactivates BMF and induces anti‐leukaemic effects.
