The molecular mechanisms of defensive-grade organic acid biosynthesis in ground beetles. [PDF]
Insect Mol BiolFormic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.

Comparative and Phylogenetic Analyses of Mitochondrial Genomes in Carabidae (Coleoptera: Adephaga). [PDF]
Ecol EvolIn this study, six complete mitochondrial genomes (mitogenomes) from the genus Harpalus are reported. Additionally, 13 cases of suspected misidentifications in public Carabidae mitogenomes from GenBank were identified, with potential corrections suggested.

A Comprehensive Exploration of Bioluminescence Systems, Mechanisms, and Advanced Assays for Versatile Applications. [PDF]
Biochem Res IntBioluminescence has been a fascinating natural phenomenon of light emission from living creatures. It happens when the enzyme luciferase facilitates the oxidation of luciferin, resulting in the creation of an excited‐state species that emits light. Although there are many bioluminescent systems, few have been identified.

Accurate Magneto‐Driven Multi‐Dimensional Droplet Manipulation
Advanced Functional Materials, Volume 33, Issue 9, February 23, 2023., 2023 Based on the in‐deep research on the mechanism of horizontal transport and vertical droplet capture/release, the noncontact magnetic micropillars array is designed to achieve 3D droplet controllable manipulation for transportation of long‐distance, across‐obstacle, and other severe working conditions.

Differences between poison and venom: An attempt at an integrative biological approach
Acta Zoologica, Volume 102, Issue 4, Page 337-350, October 2021., 2021 Abstract We discuss the use of the terms venom and poison, in the context of integrative biology, with particular emphasis on behaviour and natural history. Our purpose is to reach a broad scientific audience, especially that dedicated to zoology. The meaning of the two terms is reviewed from the secretory perspective, mainly focussed on the reptiles ...

Systematic Entomology, Volume 46, Issue 3, Page 672-684, July 2021., 2021 A new, morphologically unique lacewing larva from Cretaceous amber of Myanmar (Kachin state) is described and rendered using X‐ray phase‐contrast microtomography. The phylogenetic analysis integrating morphological and genomic data from extant and extinct taxa recovers this larva near antlions, corroborating the Cretaceous as an evolutionary ...

Spray aiming in the bombardier beetle: Photographic evidence [PDF]
Proceedings of the National Academy of Sciences, 1999 Bombardier beetles, when physically assaulted, eject a hot quinonoid spray from the tip of the abdomen. Photographic evidence is presented demonstrating that the African bombardier beetle,Stenaptinus insignis, can aim its spray in virtually any direction. It can target its individual legs, and even the individual segments of its legs.

A biomimetic study of the explosive discharge of the bombardier beetle [PDF]
International Journal of Design & Nature, 2007 A biomimetic study of the bombardier beetle’s explosive discharge apparatus was undertaken using numerical (CFD) modelling, first, of the beetle’s combustion chamber, and then of a scaled-up combustion chamber with a view to its application to devices such as gas turbine relighters.

A novel spray system inspired by the bombardier beetle [PDF]
WIT Transactions on Ecology and the Environment, 2008 In this paper we describe an experimental rig which has been built as a result of inspiration from the bombardier beetle. This beetle is such that it has the capacity to fire a spray of hot water, steam and noxious chemicals from a nozzle at the rear end of its abdomen in any direction it wishes (even over its head). An example of controlled combustion
