The coconut rhinoceros beetle, Oryctes rhinoceros (L.), (CRB) is a major pest of coconut and oil palms that causes significant damage in the Asia/Pacific region. Traditional methods for surveillance and detection of CRB involve in‐person inspections, but these are expensive to carry out and were made impossible by travel restrictions during the COVID‐19 pandemic. In this paper, a method to remotely detect possible CRB incursions and assess damage levels using publicly available images is described. The method involves searching for pictures of palms and identifying those with the distinctive V‐shaped cuts in fronds characteristic of CRB feeding. The method was validated by examining palm images from known outbreak areas and those free from the pest. We found evidence of CRB damage in the previously unreported site of Dili, Timor Leste and possible evidence of CRB in the Solomon Islands even before it was first reported in 2015. Potential limitations and broader applications of this approach are also discussed. [ABSTRACT FROM AUTHOR]

Reward Positivity (RewP) is a feedback‐locked event‐related potential component that is specifically elicited by rewarding feedback and scales with positive reward prediction error, a hallmark of reinforcement learning models. The RewP is also diminished in depression, suggesting that it may be a novel marker of anhedonia. Here, we examined if a sad mood induction offered an opportunity to causally induce a mood‐related alteration of the RewP and reward‐related learning. In Experiment 1 (N = 50 total), participants were randomly assigned to previously established sad or neutral mood induction procedures before a probabilistic selection task. This manipulation failed to induce changes in affect, suggesting that standard methods are inadequate. In Experiment 2 (N = 50 total), participants were randomly assigned to newly developed happy versus sad mood manipulations, which successfully induced large changes in affect. While the RewP was unaffected by mood induction, positive mood moderated the relationship between prediction error encoding in the RewP and reward learning, such that low positive mood and low prediction error encoding resulted in poorer reward learning. These findings provide a mechanistic example of how reduced positive affect moderates reward learning via poorer information encoding in the RewP. Our findings provide a mechanistic example of how mood affects reward learning and information content conveyed in the Reward Positivity. Additionally, our findings challenge the viability of standard mood manipulation procedures for investigating the impact of mood on reward processing and advancing a novel manipulation that is more effective.

The presence of coconut rhinoceros beetle (CRB: Oryctes rhinoceros) was reported on Efate, Vanuatu in 2019. The beetle population was determined to belong to the CRB‐S group (Clade II), similar to populations found in the Bismark Archipelago, Papua New Guinea. An introduction of the CRB‐G group (Clade IA) was discovered in 2021. Damage mapping, beetle trapping and genomic identification show that CRB‐S has now spread around about half of the island from the site of the original introduction. CRB‐G is mainly restricted to the seaport and surrounding areas of Port Vila with some outlying specimens. Through the efforts of Biosecurity Vanuatu, O. rhinoceros is still contained on the Efate group of islands and has not spread to the major copra‐producing islands in other parts of the country. Sanitation efforts appear to have reduced damage from coconut rhinoceros beetle within the zone of first arrival of the pest (Mangaliliu, Efate). Oryctes rhinoceros damage, however, is severe in areas with old plantations and limited sanitation activities (e.g. Mele/Devil's point, Efate). A concerted effort is necessary to contain the beetle on Efate and to reduce further spread and impact on the island. [ABSTRACT FROM AUTHOR]

Since the financial crisis of 2008 and the publication in 2014 of Thomas Piketty's Capital in the Twenty-First Century , income and wealth inequality have returned to public and scholarly interest. Most subsequent discussion has focused on the fall and rise of inequality in the twentieth century, but meanwhile another body of economic history literature has reconstructed long-run inequality dynamics in early modern Europe. This article surveys the new history of old inequality and discusses its three principal findings: first, that between about 1300 and about 1900 inequality increased continuously almost everywhere, meaning there is no clear link between economic growth and inequality. Secondly, the only phenomena that substantially reduced inequality were unprecedented catastrophes. Thirdly, although few things have decreased inequality, many strategies of elite wealth defence have increased it, motivating new comparative concepts like the 'inequality possibility frontier' and the 'extraction ratio'. Inequality will continue to be a subject of urgent political and moral attention, and this field opens up a research agenda that could bridge the methodological divide between economic history as practised by economists and by historians.

While the cerebellum contributes to nonmotor task performance, the specific contributions of the structure remain unknown. One possibility is that the cerebellum allows for the offloading of cortical processing, providing support during task performance, using internal models. Here we used transcranial direct current stimulation to modulate cerebellar function and investigate the impact on cortical activation patterns. Participants (n = 74; 22.03 ± 3.44 years) received either cathodal, anodal, or sham stimulation over the right cerebellum before a functional magnetic resonance imaging scan during which they completed a sequence learning and a working memory task. We predicted that cathodal stimulation would improve, and anodal stimulation would hinder task performance and cortical activation. Behaviorally, anodal stimulation negatively impacted behavior during late‐phase sequence learning. Functionally, we found that anodal cerebellar stimulation resulted in increased bilateral cortical activation, particularly in parietal and frontal regions known to be involved in cognitive processing. This suggests that if the cerebellum is not functioning optimally, there is a greater need for cortical resources. [ABSTRACT FROM AUTHOR]

The coconut rhinoceros beetle (CRB: Oryctes rhinoceros L.) is one of the most damaging pests of coconut and oil palms in the Asia/Pacific region but has not been reported from the Western Hemisphere. Here, we report a possible establishment of CRB in Nayarit, Mexico, based on an analysis of social media reports and photographs indicating the presence of the beetle and the distinctive v‐shaped notches in palm fronds caused by the beetle feeding. CRB populations are destructive once established, therefore, urgent actions are required to contain the pest and prevent damage to coconut and oil palm in the Americas. [ABSTRACT FROM AUTHOR]

In I Misers: British Responses to Extreme Saving, 1700-1860 i , Timothy Alborn has written a lively and engaging history of the cultural representation of misers, understood as individuals with an extreme preference for hoarding rather than spending money. "Before 1789", Alborn argues, "misers mainly resided in poems, novels, and plays or existed as abstractions in sermons and treatises. With earlier books on corporate governance, life insurance, and the cultural power of gold, Alborn has ranged widely across the experience of economic life in eighteenth and nineteenth century Britain.

There is an increasing sense that capitalism may have broken time itself and now is rushing human society toward a catastrophic extinction event. But despite a substantial body of literature on capitalist temporalities and another on the ruptures in historicity that attended the French Revolution, there has not yet been an exploration of the fact that the two intersect in the figure of Georges Cuvier. He and his followers formed a school of "catastrophists," who raised questions about the finitude of time and of the natural world. Their ideas were ultimately defeated, relegating catastrophism to the category of pseudoscience until it returned under a variety of different scientific, philosophical, and political guises in the 1980s. Since capital is predicated on future returns, capitalism on continual growth, and continual growth on unlimited natural resources, the lost "chrono-economics" of finitude and catastrophe offers a repressed alternative to the intellectual preconditions for industrial capitalism.

The EEG feature known as the Reward Positivity (RewP) is elicited by reward receipt and appears to reflect sensitively and specifically positive prediction errors during reinforcement learning. Yet, the RewP also is modulated by state and trait affect, suggesting that it has a more complex computational role than simple reinforcement surprise. We conducted a series of experiments aimed to investigate underlying affect processing reflected in the RewP during a reinforcement learning task. In the first experiment (N = 25), we manipulated the type of rewards a person could win (simple points or hedonically-appraised pictures). Although there were no differences in the amplitudes of the RewP for different types of rewards, there was a significant correlation between the individual rating of liking for the images and RewP amplitude. In a second experiment (N = 25), we manipulated reinforcement rates (easy vs. hard) and affective picture content (liked vs. ambivalent) to examine the potential interaction of prediction error and liking on RewP amplitude. We again found a significant relationship between liking and RewP amplitude, however, only in the hard condition. These findings suggest that the RewP reflects cortical computations of reward surprise as well as hedonic liking, identifying it as a possible nexus where multidimensional value is computed.

Introduction: Distal radius fractures are extremely common injuries affecting a wide range of patient demographics. The purpose of this study was to evaluate the outcomes of distal radius fractures managed initially with closed reduction and immobilization in either a below elbow volar–dorsal splint versus sugar-tong splint prior to conversion into a short arm cast. Methods: We performed a retrospective study of patients with distal radius fractures placed in a sugar-tong (n = 45) and volar–dorsal splint (n = 36). Anteroposterior and lateral radiographs were evaluated immediately after closed reduction and placement into either a sugar-tong or volar–dorsal splint. The radial inclination, radial length, volar tilt, and intra-articular displacement were measured. Results: The average age was not significantly different between groups (Diff: 1.1 years, P = 0.8766). Initial clinic follow-up radiographs illustrated significantly lower radial inclination in the sugar-tong group than volar–dorsal group (17.1 vs. 19, P = 0.0443). Follow-up mean radial length was not significantly lower in the sugar-tong than volar–dorsal group (8.4 vs. 9.2, P = 0.0858). Palmar tilt and articular step-off was not significantly different between splint types. The loss of reduction was 28.8% for the sugar-tong and 25.0% for the volar–dorsal group (P = 0.696). Conclusion: Our results did not demonstrate a significant difference in loss of reduction rates between the two splint groups. There was no significant difference between the sugar-tong and volar–dorsal groups in terms of loss of radial length and volar tilt. Loss of reduction was similar between groups suggesting no advantage of a volar–dorsal splint compared to a sugar-tong splint. Level of evidence: Therapeutic level III. [ABSTRACT FROM AUTHOR]

Aim Heightened craving among individuals with alcohol use disorder (AUD) has been attributed to a hypersensitivity to alcohol cues in attentional brain networks. Active mindfulness training has been shown to help improve attentional control. Here, we examined alcohol cue-related hypersensitivity among individuals with AUD who received rolling group mindfulness-based relapse prevention (MBRP) in combination with transcranial direct current stimulation (tDCS), over right inferior frontal gyrus. Methods Participants (n  = 68) viewed a series of emotionally negative, emotionally neutral and alcohol-related images. Following image presentation, participants were asked to rate their level of craving for the alcohol cues, and their level of negative affect evoked by neutral and negative cues. During the task, electroencephalogram (EEG) was recorded to capture an event-related component shown to relate to emotionally salient stimuli: the late positive potential (LPP). Participants who completed a follow-up EEG (n  = 37) performed the task a second time after up to eight sessions of MBRP coupled with active or sham tDCS. Results We found that both craving ratings and the LPP significantly decreased in response to alcohol cues from pre- to post-treatment, but not for other image cues. The magnitude of alcohol image craving reductions was associated with the number of MBRP group sessions attended. Active tDCS was not associated with craving ratings, but it was associated with greater LPP amplitudes across image types. Conclusions Taken together, these results suggest that disruption of alcohol-cue hypersensitivity in people with AUD may be a target mechanism of MBRP. [ABSTRACT FROM AUTHOR]

Purpose: Fat emboli syndrome is a rare but well-described complication of long-bone fractures classically characterised by a triad of respiratory failure, mental status changes and petechial rash. In this paper, we present the case of a patient who sustained bilateral femoral fractures and subsequently developed FES. Our aim was to review and summarise the current literature regarding the pathophysiology and management of fat emboli syndrome (FES) and propose an algorithm for treating patients with bilateral femoral fractures to reduce the risk of FES.Methods: A literature analysis was performed to determine implications in the clinical setting.Results: Currently, there exists little high-quality evidence to guide the orthopaedic surgeon in identifying patients at highest risk of FES or in preventing FES in patients with multiple long-bone fractures. However, the literature does suggest that the risk is directly related to the volume of marrow displaced and inversely related to both the time to fracture stabilisation and the respiratory reserve of the patient. Based on these correlations, we propose an algorithm for treating patients with bilateral femoral fractures, taking into consideration haemodynamic and pulmonary stability.Conclusions: Our algorithm for managing bilateral femoral fractures prioritises early stabilisation with external fixation, staged intramedullary nailing and conversion to plate fixation if FES develops. This protocol is meant to be the basis of future investigations of optimal treatment strategies. [ABSTRACT FROM AUTHOR]

Dr. Rer. Nat. Alois M. Huger had a long and distinguished career at the Institut für biologische Schädlingsbekämpfung (Institute for Biological Pest Control) Darmstadt, Germany, where he became one of the world’s leading insect pathologists. He applied his experience and understanding of insect tissues and specialist skills in microscopy to diagnosis and elucidation of the pathology of insect diseases. During his career he discovered the Oryctes nudivirus and Bacillus thuringiensis subsp. tenebrionis , and was a member of teams unravelling amber disease in scarab beetles and the role of bacteria in parthenogenesis of parasitoids. He researched and described the life cycles of microsporidian and rickettsial pathogens of insects and was the first to describe the ultrastructure of a microsporidian spore. Dr. Huger carried out diagnosis of diseased insects over a period of 55 years and has left us with many publications and a database containing thousands of records for ongoing investigation. Working with multiple pathogens in different systems, Dr. Huger obtained an overview second to none in the complexities of insect/pathogen relationships and has been at the forefront of making these discoveries benefit humanity. He is a worthy recipient of the Founders’ Lecture Honoree Award, the highest honour of the Society for Invertebrate Pathology. [ABSTRACT FROM AUTHOR]

Antigua is a small island at the northern end of the Lesser Antilles chain. Its geology is largely limited to the Upper Oligocene and it records with unusual fidelity the transition from island arc volcanism to quiescence and limestone deposition. Despite the apparent limitation of a rock record confined to a short stratigraphical interval, Antigua has a geodiversity that ranges from thick andesites through silicified logs and freshwater snails in cherts to limestones that include both shallow and deeper water facies, and fine karstic features.

Carriacou is one of the small islands in the Grenadine chain in the southern Lesser Antilles. It preserves two Miocene successions, that on the south coast shallowing upwards and separated by a probable fault from the extensively exposed turbidite sequence, called the Grand Bay Formation, on the east coast. These formations show a range of features beautifully exposed in coastal sections, including unconformities, turbidites and a starfish bed. [ABSTRACT FROM AUTHOR]

Abstract: The introduction of Oryctes virus into outbreak areas of the rhinoceros beetle, Oryctes rhinoceros (Coleoptera: Scarabaeidae), has been a major success for “classical” biocontrol with a virus and has led to a dramatic reduction in palm damage in many areas of the Asia/Pacific region. In recent years, however, there have been new reports of high levels of rhinoceros beetle damage to palms. Damage has been especially intense in SE Asia following the introduction of no-burn polices for land clearance and replanting, but outbreaks have also been reported from some Pacific Islands where control seems to have diminished over time. SE Asian studies show that there is considerable genetic variation among endemic Oryctes virus isolates and studies in new island release areas have shown rapid evolution of the virus. The consequences of such genetic variation are in need of further study. Furthermore, the taxonomic position of the virus is unclear, with its removal from the Baculoviridae to an “unassigned’ virus, reflecting its novel characteristics. Genomic sequencing could help resolve the taxonomy of the virus and provide a basis for studying strain variation. Oryctes virus has achieved wide success in the past without the benefit of molecular analysis and identification techniques. In order to fully take advantage of this unique pathogen for protection of palms, a renewed, coordinated effort centered on genetic selection and distribution of effective strains is required.

Bacteria of the genus Serratia are often associated with insects, often carry distinctive pigments and can be readily isolated onto diagnostic selective media. Bacterial marking of parasitoids has been used in studies to determine rate of oviposition and host acceptance, and it provides a rapid indication of ovipositor penetration. The technique has been applied to parasitoid-weevil and parasitoid-lepidoptera interactions. Bacterial marking has the potential to be used in parasitoid dispersal studies and its use in IPM is discussed. [ABSTRACT FROM AUTHOR]

Amber disease in the grass grub (Costelytra zealandica White) (Coleoptera: Scarabaeidae), caused by strains of the bacteria Serratia entomophila or S. proteamaculans, is characterised by cessation of feeding and clearance of the midgut. Analysis of the midgut enzyme activity in diseased grass grub larvae showed that proteolytic activity was reduced to low levels. The endopeptidases, trypsin, elastase, and chymotrypsin, were all markedly reduced in activity whereas the exopeptidases (leucine-aminopeptidase and carboxypeptidase A and B) were much less affected. There was no effect on the non-proteolytic enzymes, esterase and α-amylase. Sequential analysis of enzyme levels in the gut during onset of disease showed that proteolytic activity dropped after cessation of feeding and preceded gut clearance. In starved, uninfected larvae enzyme activity levels remained high, indicating that decline in enzyme activity is not associated with absence of food and cessation of feeding, but with the onset of disease.

Cylindrocorpus inevectus sp. n. (Cylindrocorporidae: Nematoda) is described from oil palm flowers (Elaeis guineensis Jacquin) and from the under surface of the elytra of the oil palm weevil, Elaeidobius kamerunicus (Faust) (Coleoptera: Curculionidae) in Malaysia. Cylindrocorpus inevectus sp. n. differs from previously described species in the genus (as defined in the present study) by apparently having only eight pairs of genital papillae in contrast to nine or ten pairs. In addition, the male of the new species differs from C. macrolaimus (Schneider) and C. longistoma (Stefanski) by possessing a very short tail spine. The degree of stoma coverage by the pharyngeal sleeve is suggested as an important character and is 77% in C. longistoma but 91% in C. inevectus sp. n. In the male of C. erectus the bursa does not encircle the tail tip and the tail is much stouter than that of C. inevectus sp. n. In addition, there are only two pairs of pre-anal papillae and two pairs of dorso-lateral post-anal papillae in C. erectus but three pairs of pre-anal papillae and only one pair of dorso-lateral post-anal papillae in C. inevectus sp. n. From C. curzii the new species differs in having the bursal membrane continuing around the tail tip with only two pairs of pre-anal papillae reaching the bursal rim. A key to the genera of the Cylindrocorporidae is provided and Myctolaimus rifflei (Massey & Hinds, 1970) comb. n. is proposed. Because of their parasitic association with vertebrates and morphological characters distinct from those of the saprophagic Cylindrocorporidae, such as the corpus merging with the isthmus, the absence of a valve in the corpus, a posteriorly located vulva, the presence of lateral alae, a reduced number of genital papillae and ovoviviparous nature, members of the genus Longibucca, previously placed in the Cylindrocorporidae, are placed in the new family Longibuccidae fam. n.

A series of constitutive green fluorescent protein (pGFPuv) derivatives of the bacterium Serratia entomophila (Enterobacteriaceae) were constructed, allowing the fate of cells causing amber disease ingested by the New Zealand grass grub (Costelytra zealandica, Coleoptera: Scarabaeidae) to be monitored. Examination of tissue and contents of the alimentary tract over time from ingestion, under fluorescence microscopy, revealed that the major site of S. entomophila colonisation in the grass grub is intestinal particulate matter. Visual examinations showed that wild type pathogenic strain persisted in high numbers in the grass grub intestinal tract, notably in the area of the hindgut, but the S. entomophila pADAP-free strain 5.6RC and the pADK mutant derivatives (pADK-4, -10, -13) that gave a non-feeding without gut clearance phenotype, were unable to colonise the gut. The indiscriminate colonisation of the intestinal tract particulate matter by pathogenic bacteria, rather than the colonisation of a specific site of activity, suggests that the bacterial toxins are induced and released from the bacteria while they live freely in the grass grub intestinal tract.

Coconut rhinoceros beetle (CRB; Oryctes rhinoceros [L.]; Coleoptera: Scarabaeidae) grubs feed only on decaying vegetation and usually are found in dead standing coconut trees and decaying coconut debris on the ground. However, in Guam, a significant proportion of the CRB population develops in detritus caught within the crowns of live coconut palms. This habitat extension may be due to almost total absence of predation by insectivorous birds and mammals as a result of heavy predation by the brown tree snake, Boiga irregularis (Bechsterin) (Squamata: Colubridae).

The only reported occurrence of quartz-rich sands in Jamaica is on the plains of Black River, St Elizabeth, where they outcrop in isolated pockets. The sands overlie limestones of the White Limestone Supergroup and the Coastal Group, and partly underlie Holocene peat deposits. Monocrystalline quartz, containing fluid and mineral inclusions, is the dominant mineral of the sands, with the heavy minerals, magnetite, haematite, epidote, rutile, anatase, zircon and tourmaline, occurring in minor amounts. Grain surface texture studies of the quartz grains have identified-a series of mechanical and chemical features. Grain surface texture studies of the quartz grains have identified-a series of mechanical and chemical features. Microtexture depicting marine, aeolian and pedalogical environments have been retained on the grains and represent the last three stages in the history of the grains. The petrography of the sands indicates an igneous provenance, with the major source of the detritical minerals being the Cretaceous granitoids that outcrop in the eastern half of the island. These rocks were unroofed during the uplift of Jamaica in the Late Tertiary and were subjected to extensive chemical weathering, which accounted for the breadkdown of the majority of their primary silicate minerals. Fluvial transportation and deposition of detritus onto the shelf of the south coast commenced during this period and continued into the Pleistocene, providing terrigenous sand that was modified along the coast to quartz arenite by moderate to high energy marine conditions. Tidal currents, east-west longshore currents and weathering contributed to the maturity of the sand by the time it had been transported along the shelf to the vicinity of Black River. During low sea level stands in the Pleistocene, some of this sediment that became trapped on the shelf was blown inland by south-east winds. [ABSTRACT FROM AUTHOR]

This article seeks to demonstrate that, in addition to his well-known experiments with paper money, John Law's System was a project for creating a prototype of an independent central bank. His arguments, and those of his defenders, tried to establish a legitimate political role for autonomous monetary policy, while his detractors in the 1730s and 1740s argued that central banks constituted conspiracies among cosmopolitan elites, not governance. This neglected episode in the history of economic thought established the data, rhetorical practices, and concepts for later arguments over whether the monetary system can or should be within the scope of human agency.

Background: Multiple graft options exist for anterior cruciate ligament (ACL) reconstruction in an adolescent athlete. Patellar tendon harvest can lead to anterior knee pain, while hamstring tendon harvest can affect knee flexion strength and alter mechanics. Allograft is less desirable in pediatric patients due to the higher failure rate and slight risk of disease transmission. Quadriceps tendon autograft has rarely been reported for adolescent ACL reconstruction in the USA, but is an excellent option due to its large size, low donor site morbidity, and versatility. The purpose of this study is to report the outcomes of adolescents who have undergone ACL reconstruction using quadriceps tendon autograft. Methods: Twenty-two ACL reconstructions using the quadriceps autograft were performed on 21 pediatric patients by the senior author between 2010 and 2017. The patient's demographics, injury characteristics, imaging, physical examination findings, operative findings, outcomes and sports were recorded. Results: The average age at the time of surgery was 15 years. Two patients had open physes; the remainder had closing physes. 64% of patients had additional meniscal tears and 76% had bony contusions. The average duration of follow-up was 2.8 years (range 2–5 years). At final follow-up, there were no angular deformities or leg length discrepancies. The average quadriceps atrophy of the operative leg was 4 mm. The average Lysholm score was 98. 86% of patients returned to sports. No patients had re-rupture of their operative ACL. No incidences of infections, numbness, or anterior knee pain were reported. Two patients had a second arthroscopy for re-injury, revealing new meniscal tears but intact ACL grafts. Conclusions: Use of quadriceps tendon autograft for ACL reconstruction in adolescent patients allows reliable return to sport with minimal complications. Level of evidence: Level IV, retrospective case series. [ABSTRACT FROM AUTHOR]

Coconut production in the Pacific Islands is threatened by coconut rhinoceros beetle (CRB). Distinctive feeding damage caused by adults is often the first indicator of CRB activity in a new location. Multiple approaches to damage assessment have been used, reflecting observers' experience. The lack of standardisation makes it difficult to compare CRB impacts on coconut palms over time. We examine damage assessment from three perspectives: participants, power and purpose. Participants applied binary, 3-point and 5-point damage scales consecutively to photographs of damaged palms. Participant responses were more accurate using the binary scale compared with the 5-point scale. Experience with CRB improved accuracy, but this did not wholly compensate for the effect of scale complexity. Calculations of statistical power determined minimum sample sizes to detect a 20% change in palm damage was 50 palms for the binary scale, 150 palms for the 3-point scale and > 200 palms for the 5-point scale, when the change in damage was spread across damage categories. More complex damage scales did not increase the likelihood of detecting significant changes in palm damage. With real-world examples, including detecting new outbreaks and managing established populations, recommendations were developed to standardise damage assessment for CRB on coconut palms.

Cerebellar contributions to behavior in advanced age are of interest and importance, given its role in motor and cognitive performance. There are differences and declines in cerebellar structure in advanced age and cerebellar resting state connectivity is lower. However, the work on this area to date has focused on the cerebellar cortex. The deep cerebellar nuclei provide the primary cerebellar inputs and outputs to the cortex, as well as the spinal and vestibular systems. Dentate networks can be dissociated such that the dorsal region is associated with the motor cortex, whereas the ventral aspect is associated with the prefrontal cortex. However, whether dentato-thalamo-cortical networks differ across adulthood remains unknown. Here, using a large adult sample (n = 590) from the Cambridge Center for Ageing and Neuroscience, we investigated dentate connectivity across adulthood. We replicated past work showing dissociable resting state networks in the dorsal and ventral aspects of the dentate. In both seeds, we demonstrated that connectivity is lower with advanced age, indicating that connectivity differences extend beyond the cerebellar cortex. Finally, we demonstrated sex differences in dentate connectivity. This expands our understanding of cerebellar circuitry in advanced age and underscores the potential importance of this structure in age-related performance differences. [ABSTRACT FROM AUTHOR]

The inaugural Pacific Ecological Security Conference (PESC) was held in October 2022, bringing together over 100 island leaders, policy-makers, natural resource managers and global and regional invasive species experts to prioritise the critical issue of invasive species in the Pacific Islands Region. Participants confirmed that invasive species are a major threat to building and maintaining climate resilience and adaptability of Pacific Island ecosystems, as well as food security, biodiversity, sustainable livelihoods and the protection of cultural resources and way of life. Three region-wide strategic action plans were developed to guide interventions focused on the topics of invasive ants, coconut rhinoceros beetle and the use of biological control as a pest and weed management tool. These plans were the major outcome of the PESC and, when implemented, will result in coordinated activities that take a "whole-of-Pacific" approach to invasive species biosecurity and management. Here, we briefly describe the background, planning and engagement process for the three plans, summarise any country- and territory-level data obtained through the process and detail what is planned to occur over the next few years. In addition to the adoption and implementation of the strategies as a result of this inaugural PESC, we anticipate that the PESC will become the premier regional conference aimed at reducing the entry and impacts of invasive species to improve sustainability of environments and peoples of the Pacific.

The author reflects on a balance science journalism. He mentions that investigative journalist Nick Davies states in his book "Flat Earth News" that one of the factors preventing journalists getting at the truth is the insistence of balance. He notes that there is a real risk that the anti-science view will hold sway given the scientists are not always expert communicators.

Strains of Serratia spp. showed a high level of virulence when injected into the hemocoel of larvae Costelytra zealandica, with Serratia entomophila, S. plymuthica, and S. marcescens showing significantly higher virulence than S. proteamaculans. Toxicity was independent of the amber disease-causing plasmid pADAP, suggesting a generalized Serratia toxin. [ABSTRACT FROM AUTHOR]

The article discusses medical problem experienced by bell ringers. Church bell ringers in the U.K. have been complaining of a disorder with symptoms that include vertigo, a sensation of the world caving in, anxiety, and a loss of feeling in the hands and feet. The condition has been called "ringing vertigo." The official weekly journal of the Central Council of Church Bell Ringers called "The Ringing World," has included letters attesting to problems associated with the condition. One correspondent suggested that bell ringing could trigger panic attacks due to a fear of heights, fear of falling through the floor, fear of a bell falling or of a rope catching round the neck, or fear of being unable to escape from the tower in case of a fire. However, some suggest that panic is not the cause of ringing vertigo. Rather, it could be caused by a connection between the sound of the bells and the balance mechanism of the ears.

The Melolonthinae branch of the beetle family Scarabaeidae has evolved in isolation in Aotearoa, radiating into >100 endemic species, since Aotearoa separated from Gondwanaland 82 million years ago. The group includes important pasture pests, such as the New Zealand grass grub Costelytra giveni and the manuka beetle Pyronota festiva. These beetles, like other organisms, host their own distinctive microflora including beneficial microbial symbionts and pathogens. A wide range of microbial pathogens infect the Scarabaeidae, but in Aotearoa the bacteria Serratia entomophila, S. proteamaculans and S. quinivorans (Enterobacteriaceae) are frequently found causing natural disease epizootics in C. giveni. S. entomophila is widespread in Aotearoa pasture soils, with only rare isolations of S. entomophila documented in other countries. In contrast S. proteamaculans and S. quinivorans are globally ubiquitous, and are widely distributed within Aotearoa, with some isolates active against either C. giveni or Pyronota spp. larvae, or both. Virulence determinants that impart differential host specificity and potency are located on variants of the amber disease associated plasmid (pADAP). The host specificity of the Serratia-scarab system and the absence of similar systems in other geographies, suggests that the relationship between Serratia spp. and endemic scarabs has evolved in Aotearoa.
