A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Dual‐Responsive Chitosan‐Grafted PNIPAAm Hydrogel Eye Drop Incorporating Insulin‐Imprinted Microgels for Dry Eye Syndrome Treatment

Macromolecular Bioscience, Volume 26, Issue 6, June 2026.
ABSTRACT Dry eye syndrome (DES) happens as a result of inadequate tear secretion or excessive evaporation, which leads to ocular surface irritation and damage. A major therapeutic challenge is maintaining effective drug concentrations, as topical formulations are rapidly cleared by blinking and tear turnover.
