Friends or foes? Polyploidy and competition in a grassland geophyte

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we

Magnon‐Mediated Long‐Range Entanglement in a Spin‐1/2 Heisenberg Chain Coupled to Magnetic Skyrmions

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 2, February 2026.
Magnetic skyrmions generate via their stray magnetic fields, entanglement in a nearby interacting spin chain and control the transfer of information encoded in the spin excitations. ABSTRACT Magnetic skyrmionic stray fields are functionalizable to trigger, maintain, and steer quantum entanglement in a coupled chain of localized spins.

Electrical Transport of Nb‐Doped MoS2 Homojunction P–N Diode: Investigating NDR and Avalanche Effect

open access: yesSmall, Volume 22, Issue 9, 12 February 2026.
Niobium (Nb)‐doped molybdenum disulfide (MoS2) p‐type–n‐type (p–n) homojunction diodes are engineered using thickness‐controlled homo‐interfaces. Current–voltage (I–V) characteristics reveal gate‐tunable rectification, wavelength‐dependent photoresponse, and low‐bias switching.

Pneumoperitoneum in two cats treated with trilostane for hypercortisolism

open access: yesVeterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract This report describes two cases of pneumoperitoneum in cats receiving treatment for hypercortisolism and diabetes mellitus. Both cats presented with abdominal distention and lethargy and diagnoses of pneumoperitoneum were radiographically confirmed.

The Critical Role of the Intermittent Two‐Phase Flow Topology on the Solute Dispersion in Partially Saturated Porous Media

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Intermittent flow is a widely recognized phenomenon across various fields, characterized by the spatial‐temporal fluctuations of the two‐phase topology. However, its implications for solute dispersion and mixing remain insufficiently understood.

Learning Wave Scattering Properties From Seismograms

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Heterogeneities in the Earth's crust scatter seismic waves at many scales, trapping seismic energy and producing coda waves that encode valuable information on geological structures. In regions such as volcanoes and fault systems, analyzing coda waves is essential for characterizing non‐uniform subsurface heterogeneity, improving ...
