The Theischinger fauna of South America is revised to include 11 species, nine of which are described as new to science ( Pivar, , Pivar & Moulton, , Pivar & Sinclair, , Pivar, , Pivar, , Pivar, , Pivar, , Pivar, , Pivar, ). The genus is redefined, both previously described Chilean species are redescribed, (Edwards) and (Edwards), and females are described or redescribed where possible. The first descriptions of the immature stages of South American are provided, which represent a new larval morphotype in Thaumaleidae, as larvae and pupae possess ventral adhesive structures. Furthermore, these larvae were collected from vegetation rather than rocky substrates. Illustrations and micrographs are provided for all species, and scanning electron microscopy images are included for select immatures. A key to species, distribution maps, and discussions regarding phylogenetic affinities and habitat are also included.

This study identifies the optimal combination of active and passive thermoplastic materials for producing multi-material programmable 3D structures. These structures can undergo shape changes with varying radii of curvature over time when exposed to hot water. The research focuses on examining the thermal, thermomechanical, and mechanical properties of active (PLA) and passive (PRO-PLA, ABS, and TPU) materials.

Molecular phylogenetic analyses were conducted to infer relationships between the eastern and western Nearctic Androprosopa Mik and amongst the considerably more diverse western Nearctic species. Fresh, molecular-grade material was obtained for all Nearctic Androprosopa species except two Mexican species, An. sonorensis (Arnaud & Boussy) and An.

The Thaumaleidae or madicolous midges are known from 202 species in the following seven genera: Afrothaumalea Stuckenberg, 1960 (3 species), Androprosopa Mik, 1898 (59 species), Austrothaumalea Tonnoir, 1927 (44 species), Neothaumalea Pivar, Moulton & Sinclair, 2018 (1 species), Niphta Theischinger, 1986 (14 species), Thaumalea Ruthe, 1831 (77 species) and Trichothaumalea Edwards, 1929 (4 species). In addition, one fossil genus and species are known (Mesothaumalea fossilis Kovalev).

The 3' untranslated region (3'-UTR) is the vital element regulating gene expression, but most studies have focused on variations in RNA-binding proteins (RBPs), miRNAs, alternative polyadenylation (APA) and RNA modifications. To explore the posttranscriptional function of 3'-UTR somatic mutations in tumorigenesis, we collected whole-genome data from 2413 patients across 18 cancer types. Our updated algorithm, PIVar, revealed 25,216 3'-UTR posttranscriptional impairment-related SNVs (3'-UTR piSNVs) spanning 2930 genes; 24 related RBPs were significantly enriched.
