The two closely related Oriental species of the genus , (Stål, 1867) and (Fabricius, 1787), exhibit remarkable morphological similarity, particularly in their overall red and black body coloration, including the head, thorax, and abdomen. Based on the examination of type specimens and non-type material collected from various localities of southern China, we found these two congeners were misidentified in many previous publications. Due to the restricted distribution and limited population size of in China, most taxonomic, biological, and biocontrol studies conducted under the name or should be instead attributed to To address this confusion regarding these two species, the present study clarifies the taxonomic status of the two controversial species- and .

Cardiovascular diseases (CVDs) progression is significantly modulated by epigenetic mechanisms, particularly through Sirtuin 6 (SIRT6), a key NAD⁺-dependent deacetylase in the sirtuin family. Though essential for cardiovascular homeostasis, the effects of SIRT6-mediated lysine myristoylation on CVDs progression remain largely unexplored due to detection limitations. This study developes an innovative lysine-myristoylated peptide enrichment technique, identifying mutant SIRT6 (H133Y) with high myristoyl affinity but deficient demyristoylase activity.

Tool use is widely reported across a broad range of the animal kingdom, yet comprehensive empirical tests of its function and evolutionary drivers remain scarce, predominantly focused on a few relatively intelligent vertebrate lineages. In this study, we provide a comprehensive examination of tool use behavior in the assassin bug , a specialist predator of stingless bees that exploits resin droplet from bee nest entrance to facilitate hunting. Field behavioral experiments demonstrated that resin use is critical for hunting success, as the predator uses resin to stimulate the colonial defense of stingless bees, luring attacking bees toward its optimal hunting position.

The quality of Li-solid electrolyte interface is crucial for the performance of solid-state lithium metal batteries, particularly at low stack pressure, but its dynamics during cell operation remain poorly understood due to a lack of reliable operando characterization techniques. Here, we report the evolution of Li-electrolyte interface with high spatial resolution using operando scanning electron microscopy under realistic operating conditions. By tracking the stripping process of both Li and Li-rich Li-Mg alloy anodes, we show that multiple voids coalesce into a single gap and eventually delaminate the interface in Li, whereas the voids split and collapse to partially recover interfacial contact in Li-Mg.
