We report the first live in situ observations of the iconic goblin shark (Mitsukurina owstoni) on a seamount near Jarvis Island in 2019 and on the slope of the Tonga Trench in 2024. Past observations are restricted to specimens hauled to the surface, resulting in limited knowledge of this species' ecology. These observations extend its known geographic and depth range considerably, and extend the depth range of lamniform sharks by 108 m. To further clarify habitat preferences and assess conservation status, further sampling, particularly with remote video, is required.
β-thalassaemia is considered rare in Africa; however, recent screening-based studies suggest a β-thalassaemia trait prevalence of 6% - 10% among individuals with sickle cell disease (SCD) and up to 25% in those without SCD. Co-inheritance with SCD may modify disease severity, highlighting the need for molecular confirmation. To ascertain the prevalence and genetic basis of β-thalassaemia trait in Nigerians with and without SCD. We recruited 260 participants (130 per group; aged 3 years - 69 years, median [interquartile range] = 16 [9-29]). Haemoglobin fractions were analysed using high-performance liquid chromatography, and full blood counts were obtained. A 1.6 kb region of the β-globin gene was amplified and sequenced by Sanger sequencing. Variants were annotated and haplotypes constructed. An additional 26 samples from a separate SCD cohort were also genotyped. Molecular analysis revealed a β-thalassaemia trait prevalence of < 1% in both groups, contrasting with recent screening-based reports. In addition to sickle cell, haemoglobin C, and β-thalassaemia mutations, eight other variants were identified, three of which were unique to SCD patients and in linkage disequilibrium. Sickle cell and haemoglobin C mutations occurred on the major ancestral haplotype, whereas the only β-thalassaemia mutation detected (rs33915217C>A) was associated with a minor ancestral haplotype atypical of Africa. Two rare variants (rs537944366T>C and rs33915217C>A) are reported for the first time in the Yoruba population. These findings indicate a low prevalence of β-thalassaemia trait in Nigeria and underscore the need to re-evaluate diagnostic approaches in African populations for optimal clinical management of SCD and other anaemias. This study provides the first molecular confirmation of the low prevalence of β-thalassaemia trait in the Yoruba population. It identifies two rare variants, including a β-thalassaemia mutation on a minor, atypical haplotype, and highlights the limitations of high-performance liquid chromatography, underscoring the importance of genetic testing for accurate diagnosis.

We revised the fauna of goblin spiders (Oonopidae) in the Nansei Islands, southwest Japan, and recognized 12 species of seven genera. Eleven of them were described species, namely, Gamasomorpha cataphracta Karsch, 1881, Heteroonops spinimanus (Simon, 1892), Ischnothyreus narutomii (Nakatsudi, 1942), Ischnothyreus peltifer (Simon, 1891), Ischnothyreus velox Jackson, 1908, Opopaea cornuta Yin & Wang, 1984, Opopaea deserticola Simon, 1892, Opopaea syarakui (Komatsu, 1967), Orchestina flava Ono, 2005, Xestaspis parmata (Thorell, 1890), and Xyphinus karschi (Bsenberg & Strand, 1906). A new species is described under the name of Ischnothyreus ogatai sp. nov. This paper provides photographs of each oonopid species, notes on habitat and distribution, and keys to the species. A detailed description of I. ogatai sp. nov. (for both sexes), morphological data regarding three species newly added to the Japanese fauna (X. parmata, I. velox, and O. cornata), and additional data on the genital morphology of G. cataphracta are also presented.
A rise in antisocial behaviour indicates covid-19 lockdowns disrupted our cultural evolution, says Jonathan R. Goodman.
Five striking and prey capture events of two goblin sharks were videotaped at sea for the first time, showing their extraordinary biting process. The goblin sharks swung their lower jaw downward and backward to attain a huge gape and then rapidly protruded the jaws forward a considerable distance. The jaws were projected at a maximum velocity of 3.1 m/s to 8.6-9.4% of the total length of the shark, which is by far the fastest and greatest jaw protrusion among sharks. While the jaws were being retracted, the mouth opened and closed again, which was considered a novel feeding event for sharks. Phylogenetic evidence suggested that their feeding behavior has evolved as an adaptation to food-poor deep-sea environments, possibly as a trade-off for the loss of strong swimming ability.

The family Oonopidae Simon, 1890 is composed of tiny spiders between 0.5 and 4mm (Baehr et al. 2012) that are distributed all over the world (Platnick et al. 2020; World Spider Catalog 2021). They occupy diverse habitats, mainly in tropical and subtropical regions (Platnick et al. 2020), generally associated with the soil and litter fauna (Ranasinghe Benjamin 2018). Oonopidae is among the eight most diverse spider families with 114 genera and 1872 species (World Spider Catalog 2021). Most of this diversity was discovered after 2006, as a result of the Planetary Biodiversity Inventory (PBI) project: Goblin Spider (Platnick et al. 2012). Recent molecular phylogenetic analyses recovered Oonopidae as monophyletic (Wheeler et al. 2017), hypothesis supported by the presence of a synapomorphic pair of completely fused testicles (Burger Michalik 2010). Brazil has a great diversity of Oonopidae (e.g., Brescovit et al. 2012a; Platnick et al. 2013; Feitosa et al. 2017), including the genus Predatoroonops Brescovit, Rheims Ott 2012, endemic to the Atlantic Forest, that includes 17 species (World Spider Catalog 2021). The genus can be recognized by the male chelicerae frontally modified, with one or two pairs of distally sclerotized, and sometimes branched, apophyses, and by the pars cephalica dorsally squared (Brescovit et al. 2012b). In this paper, we describe a new species of the genus, based on a male specimen from the State of Minas Gerais: Predatoroonops stani sp. nov.. Also, we give new records for Predatoroonops yautja Brescovit, Rheims Santos, 2012 from the same state and a distribution map with all the records of Predatoroonops along the Atlantic Forest.
The data we present are part of the long-term project SLAM - Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores, which was established in 2012 to monitor arthropod communities in Azorean forest habitats using standardised long-term ecological sampling. The main aim of this project is to understand how major biodiversity erosion drivers, including habitat degradation, biological invasions and climate-related pressures, affect the distribution, abundance and diversity of Azorean arthropods through time. Long-term monitoring is particularly relevant on oceanic islands, where biodiversity change may be expressed more strongly through species turnover, shifts in community composition and increases in introduced taxa than through immediate declines in total species richness. The SLAM framework also contributes to the early detection and documentation of new species occurrences, thereby improving baseline knowledge for conservation planning, biodiversity assessment and biosecurity. Sampling relies on passive flight-interception SLAM (Sea, Land and Air Malaise) traps, which are operated continuously and serviced at regular intervals to provide comparable seasonal and interannual samples. We sampled 17,064 specimens from samples from the years 2015-2021 out of which 16,491 were identified to the level of species (96.6%) or even subspecies (326 individuals) and 247 were identified to the order, family or genus level. The identified specimens belong to 17 unique orders, 82 families, 156 genera and 165 species and eight subspecies. Of these species and subspecies, 14 were endemic, 49 were native non-endemic, 86 were introduced and 24 have uncertain colonisation status.A total of 26 species were recorded for the first time on Graciosa Island, but none represents a new record for the Azores Archipelago. Amongst these newly-recorded species, two are Azorean endemics, five are native non-endemics, 16 are introduced and three have uncertain colonisation status, with most detected at very low abundance.New island records on Graciosa Island comprise nine spiders (Order Araneae), including two Azorean endemic spiders recorded for the first time on Graciosa, Neon acoreensis (jumping spider; Salticidae) and Savigniorrhipis acoreensis (dwarf sheet spider; Linyphiidae). The remaining newly-recorded spiders are: Agyneta decora (dwarf sheet spider; Linyphiidae), Enoplognatha mandibularis (cobweb spider; Theridiidae), Haplodrassus signifier (ground spider; Gnaphosidae), Neriene clathrata (sheetweb spider; Linyphiidae), Orchestina furcillata (goblin spider; Oonopidae), Theridion melanostictum (cobweb spider; Theridiidae) and Zelotes aeneus (ground spider; Gnaphosidae).New records also include eight beetles (Coleoptera): Amischa forcipata (rove beetle; Staphylinidae), Brassicogethes aeneus (pollen beetle; Nitidulidae), Carpelimus troglodytes troglodytes (rove beetle; Staphylinidae), Cathormiocerus curvipes (weevil; Curculionidae), Omosita discoidea (sap beetle; Nitudulidae), Phyllotreta procera (flea beetle; Chrysomelidae), Ptenidium pusillum (featherwing beetle; Ptiliidae) and Quedius curtipennis (rove beetle; Staphylinidae).Additional new records comprise one millipede (Diplopoda), Cylindroiulus latestriatus (julid millipede; Diplopoda, Julida) and three true bugs (Hemiptera): Buchananiella continua (minute pirate bug; Anthocoridae), Empicoris rubromaculatus (thread-legged bug; Reduviidae) and Pilophorus confusus (plant bug; Miridae).Further additions are one ant (Hymenoptera), Hypoponera eduardi (ant; Formicidae), one booklouse (Psocodea), Lepinotus reticulatus (booklouse; Trogiidae), two thrips (Thysanoptera), Anisopilothrips venustulus (thrips; Thripidae) and Ceratothrips ericae (thrips; Thripidae) and one bush-cricket (Orthoptera), Phaneroptera nana (katydid/bush-cricket; Tettigoniidae).
Global demand for ruminant milk-based products is increasing, contributing to increases in associated environmental impacts. Yet, most efforts to reduce the total environmental impact of dairy production are based on livestock breeding and manipulation of feed and manure systems. Despite the critical need for low-environmental impact breeding, life cycle assessment (LCA) has not been significantly utilized for forage and livestock trait prioritization. By combining LCA and machine learning, we inventory reductions in footprints of grass-fed dairy systems achievable by selective breeding. To measure the environmental impacts of traits and other farm changes, a pasture-centric dairy system representative of Ireland was modelled using the GOBLIN model. Milk produced in ryegrass-based dairy systems in Ireland was associated with environmental impacts of 1.08 kg CO2-eq (global warming), 0.0066 kg PO4-eq (eutrophication), 0.013 kg SO2-eq (acidification), and 1.62 MJ-eq (fossil resource depletion) per kg fat- and protein-corrected milk (FPCM), translating to annual per-hectare loads of 9281.21 kg CO2-eq, 56.75 kg PO4-eq, 108.21 kg SO2-eq, and 14,025.16 MJ-eq, respectively. Using a machine learning model trained on farm-level LCA outputs, complementarities and trade-offs were revealed across 10,000 graduated scenarios analyzed. The XGBoost Regressor achieved an outstanding R2 value of 99 % in estimating the LCA impacts. Principal component analysis and explainable artificial intelligence analyses identified dry matter digestibility, crude protein, and chemical nitrogen use as key drivers of environmental impacts in dairy systems. By optimizing input parameters, the environmental impacts of grass-based milk can be substantially reduced by breeding for 'LCA-designed ideotypes'. The optimal ryegrass ideotype identified for grass-based dairy systems can reduce; (a) global warming potential by 36.7 %, (b) acidification potential by 31 %, (c) eutrophication potential by 29 %, and (d) fossil resource depletion by 11 %, compared to current levels. We conclude that the environmental performance of ryegrass-based dairy systems can be substantially increased by new LCA-designed forage ideotypes. A more systems-based approach to livestock and forage breeding is therefore needed, as a sole focus on low-footprint livestock may overlook critical gains from forage grass improvement.
The Heartland virus (HRTV) is a tick-borne human pathogenic phlebovirus that primarily causes leukopenia and thrombocytopenia. It is transmitted by Amblyomma americanum type of tick, that is, notable for their aggressive biting behavior, affinity for human hosts, and high prevalence. Developing vaccines or immunizations against HRTV is gaining importance as a public-health preventive strategy. The current study was planned to prioritize a multi-epitope stable mRNA vaccine model against HRTV from lead B-cell and T-cell epitopes (with IC50 < 100 nM) of HRTV proteome following advanced immunoinformatics approaches. Model constructs were designed by linking the most potent, nonallergenic epitopes along with incorporation of human ribosomal protein adjuvant for immune response enhancement. The immunogenic potential of the coding vaccine molecule was examined via molecular docking against toll-like receptors immune receptors followed by normal mode analysis and molecular dynamics simulations-based energy minimization, molecular stability, and flexibility assessments. A robust, stable circular mRNA precursor of multi-epitopes vaccine model was designed by incorporating the Kozak consensus sequence, a start codon, and essential elements such as MHC class I trafficking domain (MITD), tPA, Goblin 5' and 3' Untranslated Region (UTRs), and a poly (A) tail. This strategic amalgamation ensures elevated immunogenicity and predicts a promising circular mRNA vaccine model against HRTV. The immune simulation predicted that the designed model vaccine is capable to elicit cell-mediated and humoral immune responses. The predicted circular mRNA vaccine precursor model is promising against HRTV to examine experimentally for its immunogenicity and safety features.
Global and national environmental targets for the Agriculture, Forestry and Other Land Use (AFOLU) sector need to be reconciled with increasing food and protein demands of a growing global population. Meeting climate targets in AFOLU is a tremendous challenge in countries with high ruminant livestock production and small forest carbon sinks. Using GOBLIN, an integrated assessment model that utilises a back-casting approach, 2187 future AFOLU configuration scenarios are explored to investigate whether current levels of bovine protein production in Ireland are compatible with net zero greenhouse gas (GHG) emissions by 2050. Seven proven GHG mitigation measures are combined at three levels of ambition and screened according to three definitions of net zero based on the GWP100 metric, with a focus on the integration of clover-based grasslands. Net zero was achieved in 19 % of scenarios when all GHGs require balancing by 2050. The current livestock herd configuration was incompatible with net zero, which required at least 1.5 million ha of grassland to be diverted from livestock production towards climate-positive land uses, including afforestation of close to 10 % of terrestrial land area by 2050. When applying less stringent net zero definitions based on a split gas approach, up to 63 % of explored scenarios achieved net zero. Independent of net zero definition (which must be internationally fair and transparent), results indicate that bovine protein production can only be maintained through very high deployment of ambitious technical abatement measures, alongside major land use transformation requiring large-scale structural changes in the agriculture sector.

Dengue is an important public health problem, which caused by the dengue virus (DENV), a single-stranded RNA virus consisted of four serotypes. Central nervus system (CNS) impairment in dengue usually results from DENV-2 or DENV-3 infection, which lead to life-threatening outcomes. Furthermore, neurological complications due to DENV-1 was rare especially in adult patients. A 44-year-old man without comorbidities had lethargy after hyperpyrexia and a positive DENV NS1 antigen was detected for confirming the diagnosis of dengue on day 8 of onset. Then logagnosia, decreased muscle strength, delirium and irritability were occurred even radiographic examination were normal. He was treated with low-dose hormone, sedatives and gamma goblin with a short duration of 6 days. The cerebrospinal fluid (CSF) tests were persistent normal. However, presence of DENV-1 RNA was confirmed both in CSF and serum. Furthermore, the complete sequence of the DENV isolated from the patient's serum was performed (GenBank No.: MW261838). The cytokines as IL-6, IL-10 and sVCAM-1 were increased in critical phase of disease. Finally, the patient was discharged on day 24 of onset without any neurological sequelae. Encephalopathy caused by a direct CNS invasion due to DENV-1 during viremia was described in an adult patient. Treatment with low-dose hormone and gamma goblin was helpful for admission.
The spider genus Trilacuna Tong & Li, 2007, currently comprises 32 species known from China, of which 15 species are from Yunnan and one species, i.e. T. wumanshan Tong, Yang & Zhang, 2023 is recorded from the Nangunhe Nature Reserve, Yunnan. Two new Trilacuna species, Trilacuna jimengi Dai & Tong, sp. nov. (♂♀) and Trilacuna nangunhe Dai & Tong, sp. nov. (♂♀), are described, based on specimens collected from the Nangunhe Nature Reserve, Yunnan Province. Morphological descriptions and photomicroscopy images of the new species are given.
The genus Orchestina is recorded for the first time from Xizang, China. One known species and three new species are reported: Orchestinacolubrina Liu, Henrard & Xu, 2019 (♂♀), Orchestinalini Tong & Li, sp. nov. (♂♀), Orchestinawuzu Tong & Li, sp. nov. (♂♀) and Orchestinayigong Tong & Li, sp. nov. (♂).
Post-transplant diabetes mellitus (PTDM) is a common, dynamic complication after kidney transplantation (KT) that may resolve over time. To better understand and prevent PTDM, we analyzed its prevalence, evolution, and influencing factors. Data from the French national ASTRE database at different post-transplantation periods (P) were analyzed. PTDM was defined by fasting blood glucose (FBG) ≥1.26 g/L, HbA1c ≥ 6.5%, or the use of hypoglycemic medications in kidney transplant recipients without diabetes. Patient trajectories were identified using group-based trajectory models (GBTM), and associated factors were examined. Among 2898 patients, PTDM prevalence was 27.3% at P1 (>M2, ≤M6), 21.3% at P2 (>M6, ≤M18), 19.8% at P3 (>M18, ≤M30), and 19.9% at P4 (>M30, ≤M42). Analysis of 1825 patients identified four trajectories: no PTDM (67%), late-onset PTDM (6%), remission after P1 (10%), and early, persistent PTDM (17%). Late-onset PTDM was linked to history of cardiovascular disease, higher BMI at transplantation, HCV positive status, and weight gain. Early, persistent PTDM was associated with older age, higher BMI, HVC positive status, history of cardiovascular disease, and tacrolimus use. PTDM remission was linked to lower BMI. Corticosteroids contributed to both late-onset and persistent PTDM, while switching between tacrolimus and cyclosporine did not significantly affect progression. This study confirmed the high prevalence and dynamic nature of PTDM after transplantation, emphasizing the critical role of pretransplant cardiovascular disease, BMI, and early post-transplant weight gain in the onset or remission of PTDM.
