title: Conservation and diversification of mating behavior patterns among three sibling species in the <i>Drosophila subobscura</i> species subgroup

description: Behavioral traits are known to evolve rapidly, often even preceding morphological or physiological changes. However, the genomic and neural bases for such rapid behavioral changes remain to be clarified. <i>Drosophila subobscura</i> is a rare example of a species that performs nuptial gift giving, while the mating behaviors of the other two members of the <i>subobscura</i> species subgroup, <i>D. madeirensis</i> and <i>D. guanche</i>, remain largely unstudied. In the present study, we characterize and compare mating behaviors of three sibling species of the <i>subobscura</i> species subgroup, with the aim of providing a starting point for investigating the neural mechanisms underlying reproductive behavioral divergence in the <i>subobscura</i> subgroup. We find that <i>D. madeirensis</i> males exhibit a rich repertoire of courtship behaviors—very similar to that of <i>D. suboscura</i>—including tapping, midleg swinging, proboscis extension and nuptial gift giving. In contrast, <i>D. guanche</i> males perform only tapping and lack the other premating displays, yet they still copulate successfully. We postulate that female promiscuity has promoted the loss of multiple components of the male courtship repertoire in <i>D. guanche</i>. The relatively recent divergence among these species (∼1.72 Myr between <i>D. guanche</i> and other two species) suggests that only a few genomic and neural changes underpin the striking differences in mating behavior within the <i>subobscura</i> species subgroup. This system offers a promising platform for uncovering the mechanistic basis of rapid behavioral evolution.

title: Simultaneous recording of spikes and calcium signals in odor-evoked responses of <i>Drosophila</i> antennal neurons

description: Most insects, including agricultural pests and disease vectors, rely on olfaction for key innate behaviors. Consequently, there is growing interest in studying insect olfaction to gain insights into odor-driven behavior and to support efforts in vector control. Calcium imaging using GCaMP fluorescence is widely used to identify olfactory receptor neurons (ORNs) responsive to ethologically relevant odors. However, accurate interpretation of GCaMP signals in the antenna requires understanding both response uniformity within an ORN population and how calcium signals relate to spike activity. To address this, we optimized a dual-modality recording method combining single-sensillum electrophysiology and widefield imaging for <i>Drosophila</i> ORNs. Calcium imaging showed that homotypic ab2A neurons exhibit similar odor sensitivity, consistent with spike recordings, indicating that a single ORN’s response can reliably represent its homotypic counterparts. Furthermore, concurrent dual recordings revealed that peak calcium responses are linearly correlated with spike activity, regardless of imaging site (soma or dendrites), GCaMP variant, odorant, or fly age. These findings validate the use of somatic calcium signals as a reliable proxy for spike activity in fly ORNs and provide a foundation for future large-scale surveys of spike–calcium response relationships across diverse ORN types.

title: Characterization of the Gut Virome Reveals the Presence of Norovirus Genogroup IV in the Indigenous Orang Asli from Peninsular Malaysia

description: Here we provide the viral contigs we assembled and codes used in the manuscript titled "Characterization of the Gut Virome Reveals the Presence of Norovirus Genogroup IV in the Indigenous Orang Asli from Peninsular Malaysia".

Summary

The gut virome plays an important role in health and microbial ecology, yet Indigenous communities, especially in Southeast Asia, are underrepresented and may provide unique perspectives on viral diversity and evolution. Through metagenomic and metatranscriptomic sequencing of stool samples from Indigenous Orang Asli (OA) and urban Malaysians, we identified 51,179 viral sequences representing 4,470 viral operational taxonomic units (vOTUs). Most bacteriophage vOTUs (96.6%) lacked genus-level classification and more than half (54.9%) were predicted to infectClostridia. Over one-third (37.6%) of vOTUs were specific to the Malaysian dataset compared to published virome databases. Helminth infection among OA cohort was associated with greater bacteriophage diversity, mirroring the higher gut bacterial diversity previously observed in the OA cohort. Diverse RNA viruses, including Norovirus (genogroup IV) and Enterovirus (Echovirus B18), were detected and assembled exclusively in OA, with high seropositivity to the rare Genogroup IV.1 observed in OA villagers. Hence, Indigenous communities with traditional lifestyles are an important source of uncharacterized viral diversity in defining the global human virome.

title: Imaging FlowCytobot Observations from Salt Pond, Eastham, MA (2015 and 2021) and a Dinophysis acuminata Culture Experiment

description: This dataset consists of four Imaging FlowCytobot (IFCB) datasets, comprised of images of nano- and micro-plankton triggered by particle scatter. Two datasets represent time-series observations from D. acuminata blooms in Salt Pond, Eastham, Massachusetts, collected in the summers of 2015 and 2021 from subsurface waters at an observatory platform at the pond’s center. These two datasets are a subset of all the IFCB image data collected during this time period and only represent the samples that were annotated and analyzed in the associated manuscript. The other two datasets come from a culture experiment in 2024 in which Mesodinium prey availability was manipulated across two treatments (prey-saturated and prey-limited) and tracked for 12 days. The .hdr files contain sample metadata, including field names for the .adc file. The .adc file contains flow cytometric data from each image, including particle scatter parameters. The .roi file contains all the images associated with that sample.
description: Each sample is in a .zip file that contains each of the following:
- Header file (.hdr) with metadata
- ADC file (.adc) containing flow cytometric data
- ROI file (.roi) containing raw image data
description: Instrument name: Imaging FlowCytobot (IFCB)

title: A Unified Hypothesis for Matter Stability, Aging, Time Emergence and Cosmological Phase Transitions

description: This work presents a speculative theoretical framework proposing that all material systems possess internal conjugate states coexisting in dynamic equilibrium with observable matter. These states are not identified strictly with standard antimatter, but represent a broader internal structure whose energetic phases govern material stability, aging, degradation, radioactivity, and large-scale cosmological behavior.

In this model, energy does not create the conjugate states but induces transitions between their energetic regimes. Material aging and the arrow of time are interpreted as emergent consequences of irreversible conjugate-state activation rather than fundamental primitives. The framework naturally extends from microscopic matter to planetary, astrophysical, and cosmological systems, offering reinterpretations of radioactive decay, black holes, and the Big Bang as manifestations of energetic phase transitions.

The proposal is formulated to remain compatible with established principles of thermodynamics, quantum field theory, and observational cosmology. It is presented as a phenomenological and conceptual contribution, providing a unifying interpretation and testable indirect predictions rather than a finalized or experimentally confirmed theory.

title: Transcripts of Semi-Structured Interviews with 30 Community Pharmacists on Promoting Medication Adherence in Clients with Diabetes and Hypertension: A COM-B Framework Qualitative Study

description: <b>Background:</b> Community pharmacists play a crucial role in improving medication adherence, particularly for chronic conditions such as diabetes and hypertension. In Ghana, the rising prevalence of these conditions, coupled with low adherence rates, leads to poorer health outcomes. Despite their potential, the role of community pharmacists in promoting medication adherence remains underrecognized. This study examines how pharmacists' capabilities, opportunities, and motivations influence their behaviour in improving medication adherence.<b>Methods:</b> This study utilized the COM-B framework, which posits that capability, opportunity, and motivation are essential for behavioural change. The study investigated how these three factors influenced the behaviour of 30 community pharmacists in the Greater Accra region of Ghana to improve medication adherence among clients with diabetes and hypertension. Between May and July 2023, semi-structured interviews were conducted. The interviews were recorded, transcribed, and analysed thematically to identify key factors influencing pharmacists’ practices.
