Innovative Application of Multiple Linear Regression for Analysis of Interactions of Divalent Metal Ions With Anionic Surfactant

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT The properties and aggregations of anionic surfactants change strongly in the presence of multivalent cations. Therefore, the knowledge of the binding of multivalent metal ions to the headgroups of anionic surfactants can be helpful for the applications of surfactants in various fields. This paper presents an analysis of the interactions of 14

Facilitative Effects of Alnus viridis ssp. fruticosa on Betula nana ssp. exilis Growth in Arctic Alaska

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We investigated how Siberian alder influences the growth of dwarf birch in the low Alaskan Arctic. Using growth rings, we found that Siberian alder promotes dwarf birch growth overall despite delaying and shortening the growing season through enhancing snow depths.

Life History Consequences of the Prevalence of Aggressive Males Carrying Costly Weapons

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using a soil mite system with dimorphic males, that is, aggressive, weaponized fighters and benign scramblers, we experimentally selected populations for higher proportion of fighter males for 25 generations. Populations with higher proportion of fighter males evolved faster juvenile development and higher early‐life fecundity.

Reduced Visibility of Pigment Network Under Sub‐UV Reflectance Dermatoscopy Compared to Polarised Dermatoscopy: A Novel Diagnostic Clue to Differentiate Melanomas From Nevi

open access: yesJEADV Clinical Practice, Volume 5, Issue 2, Page 620-623, June 2026.
ABSTRACT Background Melanoma accounts for more than 75% of skin cancer‐related mortality. Dermatoscopy is an evidence‐based technique for earlier detection, yet differentiating melanocytic lesions remains challenging. Sub‐UV reflectance dermatoscopy (sUVRD) uses purple light (405 nm) to visualise chromophore distribution in the skin.
