The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

open access: yesWildlife Biology, Volume 2026, Issue 3, May 2026.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

Hunting strategies, success, and sustainability: A case study in a community forest on the edge of Salonga National Park, DRC

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
In Central Africa, traditional hunting is central to the way of life of local communities. However, increasing demand for wild meat has raised concerns about the sustainability of this practice. With a year‐long analysis of hunting strategies and their impact at the outskirts of Salonga National Park, Democratic Republic of the Congo, we showed a ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

open access: yesAstronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Sensitivity of Chloroplast Movements Along an Elevational Gradient Among Three Alpine Plant Species With Different Life History Strategies

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Chloroplast movements are an important photoprotective mechanism in land plants. The magnitude of chloroplast responses depends on light conditions. We investigated variation in chloroplast movements and leaf physiological traits in three species: a deciduous dwarf shrub, Vaccinium myrtillus, and two wintergreen herbaceous perennials, Homogyne

PERICLES: A Set of Empirical Rotational Isochrones Modeled on Cool Dwarfs in Open Clusters and Wide Binaries

open access: yesAstronomische Nachrichten, Volume 347, Issue 1, January 2026.
ABSTRACT Isochrones, equal‐age curves, are widely used in astrophysics to estimate stellar ages. Classical stellar parameters are, however, very limited in their usability for main sequence stars because of their weak age‐dependence. Here, rotation period measurements provide complementary information.
