The first evidence of breeding by Crocothemis sanguinolenta and Zygonyx torridus (Odonata: Libellulidae) in Iran [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
For the first time, exuviae of Crocothemis sanguinolenta and Zygonyx torridus were collected from southern parts of Iran. Females of Z. torridus were also observed mating and ovipositing in two habitats.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices

open access: yesSmall, EarlyView.
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail

open access: yesSmall, EarlyView.
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Metalinguistic Awareness in the EFL Classroom and Beyond: Exploring the Potential of Translation Tasks

open access: yesTESOL Quarterly, EarlyView.
Abstract Current trends encouraging a move away from monolingual teaching have sparked a renewed interest in the role of translation in language instruction. Yet, there are few theoretically and empirically grounded proposals regarding specific uses of translation in the language classroom.

AML‐Net: Attention‐based multi‐scale lightweight model for brain tumour segmentation in internet of medical things

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Brain tumour segmentation employing MRI images is important for disease diagnosis, monitoring, and treatment planning. Till now, many encoder‐decoder architectures have been developed for this purpose, with U‐Net being the most extensively utilised. However, these architectures require a lot of parameters to train and have a semantic gap. Some

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

open access: yesIntegrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Establishment of Human Formative Pluripotent Stem Cell‐Like Cells Exhibiting Amniotic Differentiation Potentials

open access: yesCell Proliferation, EarlyView.
The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of

Strategic conservation prioritization through creating and updating the regional species of greatest conservation need list in the northeastern United States

open access: yesConservation Science and Practice, EarlyView.
Biodiversity is declining globally, underscoring the need for conservation strategies informed by regional expertise. In the northeastern United States, 14 state wildlife agencies and taxonomic experts developed the Regional Species of Greatest Conservation Need (RSGCN) list, revealing that global and national datasets captured only ~55% of regionally ...
