Searching for exotic scalars at fusion reactors
Part of the energy created in deuterium-tritium fusion reactors is carried away from plasma by a high-intensity neutron flux, which is then absorbed by the reactor’s inner walls.

Drought responses of European beech varied along regional environmental gradients, with greater resistance and resilience at warmer, drier sites. Tree‐ring δ13C and Ca increased during drought but were not related to growth responses. Contrasting responses among admixed species highlight the potential resilience benefits of mixed forests.

Some of the most stringent constraints on physics beyond the Standard Model (BSM) arise from considerations of particle emission from astrophysical plasmas.

Tipping Points in Bacterial Richness Amplify Extracellular Enzyme Activities in Northern Peatlands
Using a trans‐Holarctic survey in Sphagnum‐dominated peatlands, we identify a critical bacterial biodiversity threshold. Below this threshold, ecosystem function shifts, increasing enzyme activities by 60%, potentially accelerating carbon turnover. This weakens the peatland carbon sink, emphasizing the need to safeguard diversity.

A covariant description of the interactions of axion-like particles and hadrons
We present a covariant framework for analyzing the interactions and decay rates of axion-like particles (ALPs) that couple to both gluons and quarks. We identify combinations of couplings that are invariant under quark-field redefinitions, and use them ...

Contemporary Environmental Drivers of European Plant Distributions
ABSTRACT Aim Understanding the contemporary environmental conditions determining plant species distributions is crucial. Here, we quantified the relative importance of climatic, edaphic, hydrological, topographic, and land use drivers of the European vascular flora and tested whether driver hierarchies vary across species groups and ecological ...

Refined low-energy supernova constraints on lepton flavor violating axions
The supernova (SN) core, characterized by its extreme temperature and density, serves as a unique laboratory for new-physics searches. Low-energy supernovae (LESNe) provide particularly powerful probes, as their low explosion energies place stringent ...

Consensus habitat‐suitability maps identify current hotspots of species richness across the Inner Western Anatolian mountain systems. Late‐century projections (2081–2100) under SSP2‐4.5 and SSP5‐8.5 show range shifts and changing richness patterns, intensifying at higher elevations.
