Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc
The Astrophysical Journal LettersIt is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

The FEBS Journal, EarlyView.Metastasis in head and neck squamous cell carcinoma (HNSC) poses significant clinical challenges. This proof‐of‐concept study establishes patient‐derived orthotopic xenografts (PDOXs) as advanced models that closely replicate primary HNSC tumours, including local lymph node metastasis and the intricate cancer–stroma interaction.
