Discovery of seven volcanic outbursts on Io from an IRTF observation campaign 2016 to 2022

This study analyzes near-infrared measurements of Io, Jupiter's moon, observed over 170 nights from 2016 to early 2022 using the NASA Infrared Telescope Facility (IRTF). During this period, seven new volcanic outbursts, the most energetic volcanic events on Io, were discovered and characterized, increasing the total number of observed outburst events from 18 to 25. We also present simplified criteria for the thermal detection of an outburst, requiring it to be both confined to a specific location of Io and above a threshold intensity in the Lp-band (3.8 micron). Our measurements use 2 to 5 micron photometry in eclipse, Jupiter occultation, and reflected sunlight. In addition to extending the observational dataset of Io's dynamic activity, these data provide insights into the temporal and spatial distribution of outbursts on Io. Notably, all seven outbursts were detected in Io's trailing hemisphere. These include Pillan Patera and a newly discovered repeating outburst location at Acala Fluctus. We add these events to the rare category of recurring outbursts, before which Tvashtar was the only known example. We observed that another outburst at UP 254W decreased in Lp-band intensity by a factor of two in 4.5 hours. In August 2021, Io exhibited high volcanic activity when two powerful outbursts rapidly appeared, propagating East. Our findings underscore IRTF's ongoing contributions to the study of Io

Personalising Learning

This report presents the findings of the Personalising Learning project, which was commissioned by Becta. The core aim of the project is to develop a robust model of the effective use of digital technologies for the personalising of learning. Personalising learning in this context involves the tailoring of pedagogy, curriculum and learning support to meet the needs and aspirations of individual learners irrespective of ability, culture or social status in order to nurture the unique talents of every pupil. Section 2 of this report outlines the background and aims of this research project. Section 3 traces the development of the model and the accompanying learning equation. The key concept encapsulated in this model is that of overlapping action spaces, school, teaching, personal and living spaces, in which learning occurs. These spaces are populated by the key educational stakeholders: learners, their teachers, their family and peers. In each of these spaces a range of digital technologies is available to support the learner. Section 4 is a validation of the model using evidence from field research

Illegal Killing of Nongame Wildlife and Recreational Shooting in Conservation Areas

Illegal killing of nongame wildlife is a global yet poorly documented problem. The prevalence and ecological consequences of illegal killing are often underestimated or completely unknown. We review the practice of legal recreational shooting and present data gathered from telemetry, surveys, and observations on its association with illegal killing of wildlife (birds and snakes) within conservation areas in Idaho, USA. In total, 33% of telemetered long‐billed curlews (Numenius americanus) and 59% of other bird carcasses found with known cause of death (or 32% of total) were illegally shot. Analysis of spatial distributions of illegal and legal shooting is consistent with birds being shot illegally in the course of otherwise legal recreational shooting, but snakes being intentionally sought out and targeted elsewhere, in locations where they congregate. Preliminary public surveys indicate that most recreational shooters find abhorrent the practice of illegal killing of wildlife. Viewed through this lens, our data may imply only a small fraction of recreational shooters is responsible for this activity. This study highlights a poorly known conservation problem that could have broad implications for some species and populations of wildlife

Silent Phase of Johne’s Disease in Experimentally Infected Goats – A Study on New and Established Diagnostic Approaches Using Specific and Non-Specific Parameters

The current gold standard diagnostic test for Johne’s disease (JD) is detecting Mycobacterium avium subsp. paratuberculosis (MAP) from fecal samples via culture and/or PCR. Other commercially available JD diagnostic tests focus on the detection of specific antibodies within the serum or milk of infected ruminants. These tests have a high specificity but low their sensitivity and usually fail to diagnose the disease until later stages of the disease. The ideal diagnostic test should detect infected animals already during the silent phase. Here, we evaluate the use of new and established approaches to define the silent phase of JD in experimentally infected goats. None of the established diagnostic tests or new approaches for the detection of humoral and cellular immune responses were positive during the first year of infection. Only the characterization of various subsets of peripheral blood leukocytes and the weight development gave some indication for the presence of a chronic, but silent, infection. Weight differences were present throughout the first year. In addition, some of the subsets of leukocytes (WC1+ T cells, MHC class II+ leukocytes, CD1+ leukocytes, CD14+ granulocytes, and CD14+/MHC class II+ granulocytes) demonstrated significant differences, but only at certain time points

Health-related quality of life in people with aphasia: Implications for fluency disorders quality of life research

Abstract It is increasingly important that clinicians address the health-related quality of life (HRQOL) of adults with communication disorders in clinical practice. The overall aim of this paper is to draw conclusion about the suitability of the Short Form 36 Health Survey for the communication disorders of aphasia and stuttering. This study reports on the impact of post-stroke aphasia on 30 Australian older adults’ HRQOL. It also comments on the capacity of the SF-36 to measure HRQOL in this population, specifically whether it is sensitive to the three known determinants of post-stroke HRQOL – emotional, physical and social functioning. Comparisons with other data are made to assist interpretation of the SF-36 subscale scores: with 75 older adults with no history of neurological conditions; and with data from the 1995 National Health Survey data. The main findings are: (1) adults with post-stroke aphasia have similar HRQOL to their peers on six subscales, but significantly lower Role emotional and Mental health HRQOL; (2) a substantial number of aphasic adults reported depressive mood; and (3) aphasic adults with depressive mood have significantly worse HRQOL on six subscales than aphasic adults without depressive mood, but similar Role emotional and Body pain HRQOL. In conclusion, stroke and aphasia have minimal impact on older adults’ HRQOL as measured by the SF-36, which conflicts with an established evidence base of the negative consequences of aphasia on life. Thus, the SF-36 is not advisable for use with aphasic adults. Implications of these findings for aphasia and stuttering are discussed. Educational objectives: The reader will be able to: (a) describe the impact of aphasia and depressive mood on quality of life; (b) compare the impact of aphasia on the quality of life of adults to adults who do not have aphasia; (c) describe the similarities and differences between quality of life of adults with aphasia and adults who stutter; and (d) describe the strengths and limitations of the SF-36 as a measure of quality of life in adults who stutter versus adults with aphasia

A posture and mobility training package for care home staff: results of a cluster randomised controlled feasibility trial (the PATCH trial)

Background: provision of care for care home residents with complex needs is challenging. Physiotherapy and activity interventions can improve well-being but are often time-limited and resource intensive. A sustainable approach is to enhance the confidence and skills of staff who provide care. This trial assessed the feasibility of undertaking a definitive evaluation of a posture and mobility training programme for care staff. Design and setting: a cluster randomised controlled feasibility trial with embedded process evaluation. Ten care homes in Yorkshire, United Kingdom, were randomised (1:1) to the skilful care training package (SCTP) or usual care (UC). Participants: residents who were not independently mobile. Intervention: SCTP—delivered by physiotherapists to care staff. Objectives and measurements: key objectives informed progression to a definitive trial. Recruitment, retention and intervention uptake were monitored. Data, collected by a blinded researcher, included pain, posture, mobility, hospitalisations and falls. This informed data collection feasibility and participant safety. Results: a total of 348 residents were screened; 146 were registered (71 UC, 75 SCTP). Forty two were lost by 6 months, largely due to deaths. While data collection from proxy informants was good (>95% expected data), attrition meant that data completion rates did not meet target. Data collection from residents was poor due to high levels of dementia. Intervention uptake was variable—staff attendance at all sessions ranged from 12.5 to 65.8%. There were no safety concerns. Conclusion: care home and resident recruitment are feasible, but refinement of data collection approaches and intervention delivery are needed for this trial and care home research more widely

Non-canonical Wnt signalling regulates scarring in biliary disease via the planar cell polarity receptors

The number of patients diagnosed with chronic bile duct disease is increasing and in most cases these diseases result in chronic ductular scarring, necessitating liver transplantation. The formation of ductular scaring affects liver function; however, scar-generating portal fibroblasts also provide important instructive signals to promote the proliferation and differentiation of biliary epithelial cells. Therefore, understanding whether we can reduce scar formation while maintaining a pro-regenerative microenvironment will be essential in developing treatments for biliary disease. Here, we describe how regenerating biliary epithelial cells express Wnt-Planar Cell Polarity signalling components following bile duct injury and promote the formation of ductular scars by upregulating pro-fibrogenic cytokines and positively regulating collagen-deposition. Inhibiting the production of Wnt-ligands reduces the amount of scar formed around the bile duct, without reducing the development of the pro-regenerative microenvironment required for ductular regeneration, demonstrating that scarring and regeneration can be uncoupled in adult biliary disease and regeneration

PATCH: posture and mobility training for care staff versus usual care in care homes: study protocol for a randomised controlled trial

Background: Residents of care homes have high levels of disability and poor mobility, but the promotion of health and wellbeing within care homes is poorly realised. Residents spend the majority of their time sedentary which leads to increased dependency and, coupled with poor postural management, can have many adverse outcomes including pressure sores, pain and reduced social interaction. The intervention being tested in this project (the Skilful Care Training Package) aims to increase the awareness and skills of care staff in relation to poor posture in the older, less mobile adult and highlight the benefits of activity, and how to skilfully assist activity, in this group to enable mobility and reduce falls risk. Feasibility work will be undertaken to inform the design of a definitive cluster randomised controlled trial. Methods: This is a cluster randomised controlled feasibility trial, aiming to recruit at least 12–15 residents at each of 10 care homes across Yorkshire. Care homes will be randomly allocated on a 1:1 basis to receive either the Skilful Care Training Package alongside usual care or to continue to provide usual care alone. Assessments will be undertaken by blinded researchers with participating residents at baseline (before care home randomisation) and at three and six months post randomisation. Data relating to changes in physical activity, mobility, posture, mood and quality of life will be collected. Data at the level of the home will also be collected and will include staff experience of care and changes in the numbers and types of adverse events residents experience (for example, hospital admissions, falls). Details of NHS service usage will be collected to inform the economic analysis. An embedded process evaluation will explore intervention delivery and its acceptability to staff and residents. Discussion: Participant uptake, engagement and retention are key feasibility outcomes. Exploration of barriers and facilitators to intervention delivery will inform intervention optimisation. Study results will inform progression to a definitive trial and add to the body of evidence for good practice in care home research. Trial registration: ISRCTN Registry, ISRCTN50080330.

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

DIY Methods 2022 Conference Proceedings

As the past years have proven, the methods for conducting and distributing research that we’ve inherited from our disciplinary traditions can be remarkably brittle in the face of rapidly changing social and mobility norms. The ways we work and the ways we meet are questions newly opened for practical and theoretical inquiry; we both need to solve real problems in our daily lives and account for the constitutive effects of these solutions on the character of the knowledge we produce. Methods are not neutral tools, and nor are they fixed ones. As such, the work of inventing, repairing, and hacking methods is a necessary, if often underexplored, part of the wider research process. This conference aims to better interrogate and celebrate such experiments with method. Borrowing from the spirit and circuits of exchange in earlier DIY cultures, it takes the form of a zine ring distributed via postal mail. Participants will craft zines describing methodological experiments and/or how-to guides, which the conference organisers will subsequently mail out to all participants. Feedback on conference proceedings will also proceed through the mail, as well as via an optional Twitter hashtag. The conference itself is thus an experiment with different temporalities and medialities of research exchange. As a practical benefit, this format guarantees that the experience will be free of Zoom fatigue, timezone difficulties, travel expenses, and visa headaches. More generatively, it may also afford slower thinking, richer aesthetic possibilities, more diverse forms of circulation, and perhaps even some amount of delight. The conference format itself is part of the DIY experiment
