Generation of In Vivo‐Inspired 3D Collagen Models for Guided Tumor Invasion In Vitro

open access: yesCurrent Protocols, Volume 6, Issue 1, January 2026.
Abstract Porous collagen hydrogels are widely used to model dynamic cell‐extracellular matrix (ECM) interactions relevant to inflammation, wound healing, and cancer invasion. To improve the physiological relevance of such assays, it is essential to incorporate architectural ECM characteristics identified in vivo that may affect the mechanical and ...

Globular Clusters GMRT Pulsar Search (GCGPS). I. Survey Description, Discovery and Timing of the First Pulsar in NGC6093 (M80)

open access: yesThe Astrophysical Journal
This paper describes the new Globular Clusters GMRT Pulsar Search survey. This survey aims to find millisecond pulsars (MSPs) in the globular clusters (GCs) of the Milky Way using the upgraded Giant Metrewave Radio Telescope (uGMRT).

Male‐Biased Adult Mortality in the Great Bustard Is Consistent With High Reproductive Costs and Aggravated by Anthropogenic Impact

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Annual survival of great bustards (Otis tarda) was lower in males than in females, with minimum values just after the mating and incubation period, respectively, a pattern that is consistent with the reproductive cost hypothesis. Survival was lower in Madrid, a highly anthropized region (males: 0.874, females: 0.931), than in Villafáfila, where good ...

Reversal Asymmetry of Reciprocal Metasurface Enables Ultra‐Compact Varifocal Reflective Lens

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The possibility of breaking the reversal symmetry of a lens without violating reciprocity is demonstrated. The freedom provided is utilized to realize an ultra‐compact reflective varifocal lens‐doublet based on a flat metasurface lens and a piezoelectric actuated micromirror.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie

open access: yesPhysik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

Unraveling Size Dependent Bi‐ and Tri‐Exciton Characteristics in CdSe/CdS Core/Shell Quantum Dots via Ensemble Time Gated Heralded Spectroscopy

open access: yesSmall, Volume 22, Issue 1, 2 January 2026.
The size‐dependent biexciton binding energy in CdSe/CdS quantum dots is measured via ensemble time‐gated heralded spectroscopy, showcasing a transition between repulsive and attractive exciton‐exciton interactions. The spectrum and dynamics of two triexciton transitions are resolved and isolated from emission of multiexcitons of higher order.
