Summary: Organisms in regions with alternating seasons develop different phenotypes in each season, which are adaptations to the environment. This study investigates how gene expression, alternative splicing, and miRNA-mediated gene silencing vary in Bicyclus anynana butterfly hindwing tissue at different developmental timepoints and rearing temperatures. The results suggest that developmental transitions and hormone pulses have a greater impact on transcriptomic patterns than rearing temperatures. The study also identifies differentially expressed genes, differentially spliced genes, and miRNA-regulated genes between the seasonal forms.

Summary: This study investigates the fundamental mechanisms of interaction between propeller wake vortices and untipped non-lifting wings, revealing the complex interaction between propeller tip and blade trailing vortices and wings under different loading conditions. The behavior of tip vortices is strongly influenced by their interaction with the wing's boundary layer during encounter and early penetration phases, leading to asymmetrical evolution and breakdown of vortex portions along the pressure and suction sides of the wing.

Summary: Organismal development is a complex process characterized by reproducibility and tolerance despite its complexity, implying hidden simplicities. By studying natural phenotypic variation in fruit fly wings, researchers identified a highly constrained set of wing phenotypes that could be described by a single integrated mode. This work demonstrates the presence of constraints that funnel environmental inputs and genetic variation into phenotypes along a single axis in morphological space, providing insights into the robustness of complex forms and potential for evolutionary variations.

Summary: This study identified a transcription factor Zfh1 as an upstream regulator in the development of long and short wing morphs in planthoppers. The balance between the Zfh1-FoxO and insulin signaling cascades plays a crucial role in determining the wing morphological diversity. The findings provide insights into the molecular mechanisms underlying wing polyphenism and the evolution of wing morphological diversity in insects.

Summary: Developmental arrest in preimplantation embryos is a major cause of assisted reproduction failure. This review comprehensively evaluates the biological impacts of molecular biological defects, including epigenetic disturbances, ART processes, and genetic variants, on embryonic development. The creation of diagnostic gene panels and potential ways of preventing developmental arrests are also discussed.

Summary: Research has uncovered differences in gene expression between two species of spadefoot toads in response to a shared environmental risk, particularly genes related to lipid, cholesterol, and steroid biosynthesis and metabolism. These differences may have played a crucial role in the genetic accommodation of developmental plasticity in this biological system.

Summary: In this study, the gene expression abundance related to wing development and metamorphosis in the white-spotted flower chafer Protaetia brevitarsis seulensis was explored based on large-scale RNA-seq data. The transcriptome assembly consisted of 23,551 high-quality transcripts with a coverage of approximately 96.7%. A total of 265 wing development genes, 19 metamorphosis genes, and 1,314 candidates were identified. Network centrality analyses revealed that wing development- and metamorphosis-related genes had a high degree of betweenness centrality. These genes were expressed most highly in eggs, moderately in pupa and adults, and lowest in larva. This study provides valuable clues for understanding the genetic modulation mechanism of wing development and metamorphosis in P. b. seulensis.

Summary: The study analyzed genome-wide DNA methylation in 649 AML patients and identified 13 epitypes, revealing associations between different epitypes and recurrent mutations in patients. Results showed unique DNA methylation patterns among epitypes, with stem-cell-like epitypes associated with poor survival and up-regulated stem cell gene expression signatures. Additionally, a DNA methylation signature involving STAT motifs associated with FLT3-ITD mutations was identified, and DNA methylation signatures were stable at relapse for most patients, with rare epitype switching observed.

Summary: This study used functional MRI to investigate how the neural dynamics of different brain networks contribute to explaining individual differences in language learning. The research identified that certain brain regions represent newly acquired language knowledge and the connectivity between these regions is enhanced in more successful learners. The findings suggest that neural fingerprints derived from multiple neural network dynamics can explain not only the degree of success but also patterns of language learning across different components.

Summary: Exposure to ozonated carbamazepine (CBZ) was found to result in cardiovascular-related malformations and reduced heart rate in zebrafish embryos, along with a lack of swim bladder inflation. Through gene co-expression analysis, two co-expression networks and their upstream transcription regulators were identified, offering mechanistic explanations for the observed toxicity phenotypes. The study presents a novel application of gene co-expression analysis elucidating potential toxicity mechanisms of an ozonated pharmaceutical with environmental relevance.

Summary: Peer developmental relationships, as an alternative to formal mentorships, play an important role in providing career and psychosocial support. This study investigates the factors contributing to the dynamics and persistence of these relationships, and finds that reciprocity, trust, and trust asymmetry are crucial in forming and maintaining multiplex peer developmental relationships. The study also reveals that early provision of psychosocial support and the presence of mutuality further enhance the likelihood of developing and sustaining such relationships.

Summary: This study analyzed the global changes in transcript expression profiles in two meristematic tissues of two genotypes with different sensitivities to photoperiods. A large number of differentially expressed genes were identified, and some genes related to the photoperiod and flower development pathways were found. In addition, marker genes for distinguishing between the vegetative and reproductive stages were identified. These findings provide valuable insights into the molecular factors underlying meristematic development and photoperiod adaptation in the common bean.

Summary: The differential growth of imaginal discs in ants generates distinct castes, with the worker caste in Pheidole showing unique coordination in the development of rudimentary forewing discs in soldier larvae. The increase in volume of the soldier rudimentary forewing discs is coordinated with larval size and with other imaginal discs, suggesting novel patterns of inter-organ coordination specific to Pheidole ants. This study highlights the potential for rudimentary organs to acquire novel regulatory functions during development and evolution.

Summary: This study investigated the geographical distribution of worker polymorphism in ants and found that arid regions are hotspots of superorganism complexity. Tropical savannahs and deserts have the highest densities of polymorphic ants, despite being species-poor relative to tropical or temperate forests. The possible adaptive advantages of worker polymorphism in arid environments are discussed.
