A Chaos‐Driven Image Encryption Method With Möbius Transformations and Finite‐Ring Diffusion

Engineering Reports, Volume 8, Issue 11, November 2026.
This paper presents a lightweight yet highly secure image encryption framework integrating chaotic dynamics, HKDF‐S3 key expansion, and Möbius‐Affine transformations. The proposed scheme achieves strong confusion and diffusion with minimal computational cost, demonstrating high resistance to differential and chosen‐plaintext attacks through dynamic key

The National Allergy Centre of Excellence–Addressing Australia's Allergy Burden

Clinical &Experimental Allergy, Volume 56, Issue 11, Page 1385-1396, November 2026.
Australia's high allergy burden prompted a national response, leading to the establishment of the National Allergy Centre of Excellence (NACE) in 2022. The NACE has advanced research infrastructure, collaboration, and consumer‐centred care through four pillars, achieving global recognition and accelerating translation into policy, practice, and ...

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Helix Ring Peptide U₁₁ from the Venom of the Ant, Tetramorium bicarinatum, Acts as a Putative Pore-Forming Toxin

Membranes
An insect neuroactive helix ring peptide called U11-MYRTX-Tb1a (abbreviated as U11) from the venom of the ant, Tetramorium bicarinatum. U11 is a 34-amino-acid peptide that is claimed to be one of the most paralytic peptides ever reported from ant venoms ...

Loss, persistence and reversal of phenotypic traits

Biological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

The complexity and structural diversity of ant venom peptidomes is revealed by mass spectrometry profiling

, 2015
Copyright © 2015 John Wiley & Sons, Ltd. Rationale Compared with other animal venoms, ant venoms remain little explored. Ants have evolved complex venoms to rapidly immobilize arthropod prey and to protect their colonies from predators and pathogens ...

Ants as flower visitors : floral ant-repellence and the impact of ant scent-marks on pollinator behaviour [PDF]

, 2012
As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the occurrence of floral traits that ...

Predicting cross reactivity between the fire ant venom allergen Sol i 3 and the antigen 5 from vespid venoms based on molecular modeling computing

Journal of Immunotoxicology
The fire ant Solenopsis invicta is an aggressive invasive species whose venom frequently triggers hypersensitivity reactions, including severe anaphylaxis. In endemic regions, its stings represent a significant cause of Hymenoptera-related allergy.
