AI Article Synopsis

  • The study aims to clarify the size of Germany's insect diversity, focusing on challenging families of flies (Diptera) and wasps (Hymenoptera) that are not well understood.
  • Utilizing over 48,000 DNA barcodes from flies collected in southern Germany, researchers assessed known species to estimate the number of undiscovered species in four difficult fly families: Cecidomyiidae, Chironomidae, Phoridae, and Sciaridae.
  • The findings indicate that Germany potentially has between 1800-2200 undiscovered species in these families, suggesting that expanding the research to other regions could reveal even more biodiversity.

Article Abstract

Determining the size of the German insect fauna requires better knowledge of several megadiverse families of Diptera and Hymenoptera that are taxonomically challenging. This study takes the first step in assessing these "dark taxa" families and provides species estimates for four challenging groups of Diptera (Cecidomyiidae, Chironomidae, Phoridae, and Sciaridae). These estimates are based on more than 48,000 DNA barcodes (COI) from Diptera collected by Malaise traps that were deployed in southern Germany. We assessed the fraction of German species belonging to 11 fly families with well-studied taxonomy in these samples. The resultant ratios were then used to estimate the species richness of the four "dark taxa" families (DT families hereafter). Our results suggest a surprisingly high proportion of undetected biodiversity in a supposedly well-investigated country: at least 1800-2200 species await discovery in Germany in these four families. As this estimate is based on collections from one region of Germany, the species count will likely increase with expanded geographic sampling.

The synaptonemal complex (SC) is a protein-rich structure essential for meiotic recombination and faithful chromosome segregation. Acting like a zipper to paired homologous chromosomes during early prophase I, the complex is a symmetrical structure where central elements are connected on two sides by the transverse filaments to the chromatin-anchoring lateral elements. Despite being found in most major eukaryotic taxa implying a deeply conserved evolutionary origin, several components of the complex exhibit unusually high rates of sequence turnover.

Superior Multimodal Luminescence in a Stable Single-Host Nanomaterial with Large-Scale Synthesis for High-Level Anti-Counterfeiting and Encryption.

Multimode luminescent materials exhibit tunable photon emissions under different excitation or stimuli channels, endowing them high encoding capacity and confidentiality for anti-counterfeiting and encryption. Achieving multimode luminescence into a stable single material presents a promising but remains a challenge. Here, the downshifting/upconversion emissions, color-tuning persistent luminescence (PersL), temperature-dependent multi-color emissions, and hydrochromism are integrated into Er ions doped CsNaYbCl nanocrystals (NCs) by leveraging shallow defect levels and directed energy migration.

Vanadium-based oxides have garnered significant attention for aqueous zinc batteries (AZBs), whereas sluggish Zn diffusion and structural collapse remain major challenges in achieving high-performance cathodes. Herein, different structures of iron-vanadium oxides were fabricated by modulating the amount of vanadium content. It is found that the porous Mott-Schottky heterojunction composed of FeVO and FeVO mixed phase was used to construct a self-generated FeVO-5 structure, which could lower the diffusion barrier and improve the electron transport derived from the formed built-in electric field at the interface, showing faster reaction kinetics and improved capacity compared with the singe-phase FeVO-1.

Animals alter their behavior in response to changes in the environment. Upon encountering hyperosmotic conditions, the nematode worm initiates avoidance and cessation of egg-laying behavior. While the sensory pathway for osmotic avoidance is well-understood, less is known about how egg laying is inhibited.

ConspectusWater-in-salt electrolytes (WiSEs) are promising electrolytes for next-generation lithium-ion batteries (LIBs), offering critical advantages like nonflammability and improved safety. These electrolytes have extremely high salt concentrations and exhibit unique solvation structures and transport mechanisms dominated by the formation of ion networks and aggregates. These ion networks are central to the performance of WiSEs, govern the transport properties and stability of the electrolyte, deviating from conventional dilute aqueous or organic electrolytes.
