Summary: Mimicry is ubiquitous in nature, yet understanding its origin and evolution is complicated by the scarcity of exceptional fossils that enable behavioral inferences about extinct animals.Here we report bizarre true bugs (Hemiptera) that closely resemble beetles (Coleoptera) from mid-Cretaceous amber.The unusual fossil bugs are described as
Atopic dermatitis (AtD) is one of chronic recurrent diseases.One of the most frequent complications of atopic dermatitis Mains Terminal Block in children is secondary bacterial infection which plays a significant role in the pathogenesis of AtD and is a relevant factor for its aggravation.It is recurrent bacterial infection that often causes AtD re
Batteries We present a study of the Ca ii K and IR triplet lines in a sample of classical T Tauri stars in the Chamaeleon I star-forming region.We study X-shooter spectra of the stars in the sample and find that in some of these stars the Ca ii lines are much weaker than expected from their H line fluxes and mass accretion rates.Since the Ca ii K l
