open access: yesClinical &Translational Immunology, Volume 15, Issue 3, 2026.
Abstract Helminths infect nearly 2 billion people worldwide and are a major cause of chronic morbidity in low‐resource regions. Unlike bacterial and viral pathogens that elicit protective memory, helminths actively remodel host immunity to enable their years‐long persistence and reinfection.

Oldest Cretaceous latimeriid elucidates cranial evolution in derived and extant coelacanths (Actinistia, Latimeriidae)

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 2, Page 354-362, March 2026.
We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.
