Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

Oikos, Volume 2026, Issue 5, May 2026.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

Oxytocin Neuron‐Specific CAPS2 Deficiency in Mice Impairs Hippocampal Plasticity and Long‐Term Memory Through Reduced ERK Phosphorylation in the Ventral hippocampus

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
The CAPS2 cKO mouse, characterized by reduced oxytocin release, exhibits impaired cognitive function and disrupted hippocampal long‐term potentiation. ABSTRACT Oxytocin (OXT), a neuropeptide produced in the paraventricular nucleus (PVN) of the hypothalamus, regulates social behaviour, stress responses, and memory. Our previous studies demonstrated that

Softening the Border: A Capacities Approach to the Perception–Cognition Distinction

Philosophy and Phenomenological Research, Volume 112, Issue 3, Page 707-723, May 2026.
ABSTRACT Approaches to the perception–cognition distinction tend toward two extremes. Many embrace a hard border, treating perception and cognition as mutually exclusive, non‐overlapping categories. By contrast, eliminativism denies that any principled, theoretically useful distinction exists between perception and cognition.

Sums of three positive cubes

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract We survey ideas surrounding the study of the number of integers that can be represented as the sum of three positive cubes. We focus on the early contribution of Davenport using elementary techniques, and the subsequent developments due to Vaughan, which introduced Fourier analysis and mirrored many of the important developments of the Hardy ...

Adipocyte‐Derived Exosomal miR‐5099 Mitigates M1 Macrophage Polarization and Adipose Inflammation via c‐Met/NF‐κB Axis to Improve Metabolic Health

Advanced Science, Volume 13, Issue 24, 27 April 2026.
Celastrol upregulates adipocyte‐derived exosomal miR‐5099, suppressing the macrophage c‐Met/NF‐κB axis to mitigate pro‐inflammatory M1 polarization and adipose inflammation. These miR‐5099‐enriched exosomes also act as endocrine signals targeting the liver, muscle, and adipocytes to significantly enhance systemic insulin sensitivity.

Barn owls exert top‐down effects on the abundance and behavior of rodent pests

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Predators can exert top‐down effects on their prey by direct consumption, by imposing risk of predation, or a combination of both. However, empirical evidence for these effects is mixed and inconsistent. Barn owls in agriculture present a system with attributes that should, according to theory, lead to strong top‐down effects, but research is ...

Behavioral Selection of Coprophagy in an Arid‐Adapted Herbivore: Does a Compatibility–Risk Gradient Shape Selective Coprophagy?

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Estimated amount of each scat type consumed by Texas tortoises (Gopherus berlandieri) during 48‐h feeding trials expressed as area under the cumulative‐consumption curve (AUC; ±95% CI). Coprophagy is prevalent in Texas tortoises, and tortoises selectively choose feces along a compatibility‐risk gradient, which is evolutionarily meaningful.

Cyclic 2.5D Perceptual Loss for Cross‐Modal 3D Medical Image Synthesis: T1w MRI to Tau PET

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
The proposed deep learning framework for estimating regional [18F]flortaucipir tau PET SUVRs from 3D T1w MRI. To this end, we introduce two technical innovations: a cyclic 2.5D perceptual loss with alternating neuroanatomical plane wise optimization, and a by manufacturer PET SUVR standardization that reduces inter scanner variability.

Exploring the genetic overlap between substance use disorder and educational attainment

Addiction, Volume 121, Issue 4, Page 908-921, April 2026.
Abstract Background and aims Substance use disorder (SUD) is a polygenic psychiatric condition characterized by persistent drug use despite negative consequences. Several studies support that higher cognitive performance and educational attainment (EA) are associated with a reduced risk for SUD.
