THE UK FIREBALL ALLIANCE: LESSONS LEARNED FROM TWO METEORITE FIELD SEARCHES IN THE UK

Introduction: The UK currently has six meteor camera networks that are coordinated through the UK Fireball Alliance (UKFAll) [1]. Together, these networks currently image much of the UK's night sky. Since its formal establishment in 2020, the UKFAll has organised field searches following two detected fireball events that dropped meteorites in the UK: one at 21:54 (UTC) 28th February 2021 in Gloucestershire, England, and another at 23:45 (UTC) 14th April 2022 in Shropshire, England. The former fireball detection led to the recovery of the Winchcombe CM chondrite, the first UK meteorite in 30 years [2-4], whilst our search for the Shropshire meteorite have not yet located any stones. Here, we report some lessons learned as a citizen-science and academic collaboration, and from engaging with both local and national communities in searching for meteorites in Gloucestershire and Shropshire, UK. Camera Networks: UKFAll includes the UK Meteor Network (UKMON), Network for Meteor Triangulation and Orbit Determination (NEMETODE), the UK Fireball Network (UKFN), the Fireball Recovery and InterPlanetary Observation Network (FRIPON), the Global Meteor Network (GMN), and the AllSky7 network. Orbital calculations and dark flight modelling are a collaborative effort by researchers from the Global Fireball Observatory based at Curtin University, Australia, as well as the University of Western Ontario, Canada, and FRIPON, France. Winchcombe: Since the Winchcombe meteorite fell during a national lockdown, we issued a press release asking residents in Gloucestershire to report possible meteorite finds following the fireball, as opposed to sending a search party immediately. This approach was successful, with the Wilcock family waking to find a pile of dark rocks and powder on their driveway, and having seen the news, collecting the material and contacting the UKMON. Following verification of the meteorite fall, and additional refinement of the strewn field, a small (~15 scientists) search party assembled in Gloucestershire on 4th March 2021. This led to the recovery of the largest 152 g stone at Rushbury House farm on 6th March 2021. Field Experience: Members of UKFAll with meteorite searching experience led small teams of 4 - 8 people. The search was conducted in a unique situation due to COVID. Care was taken to remain socially distanced at all times, which made coordination of the search efforts challenging. Positive engagement with the local community was prioritised from the outset, with team leaders contacting landowners for permission to search and emphasising our safety precautions and risk assessments. News of the meteorite fall spread quickly, and residents were very hospitable and enthusiastic about our activities. The UK countryside is full of "meteorwrongs", and the rural terrain was difficult to search due to long grass, bushes etc. A game was devised to help boost morale - and to see if a meteorite would be found in that field - where a convincing meteorwrong was thrown into each new area by one team member to be found by the search team. During the field search, we also received many enquiries. These were managed by dedicated UKFAll team members, who replied to emails and visited potential meteorite finds in the area. The press interest in the story following the announcement that the meteorite had been found was significant, with journalists soon arriving in Winchcombe. This press release came after the main UKFAll search had ended, and there were many requests from the the media for interviews. Following several busy days, a key lesson learned was to the need to have a designated media liaison for any future press releases. Shropshire: This meteorite search was carried out over six days by ~20 scientists in an agricultural area south of Shrewsbury that included grazing land for sheep, wheat and rapeseed fields, and woodland. Searching in mid-April proved more challenging due to the increased vegetation cover. In order to train more people in meteorite hunting strategy, search line leaders were alternated each day. An initial small team arrived for the first two days to engage with the community. This "recon" was used to assess the terrain, identify key areas, and obtain permissions, and to avoid inundating small communities with search teams without advance notice. Early on, we engaged with a business owner, who helped to spread the word using local social media groups. Within 24 hours, most residents in the strewn field were aware of the meteorite fall and our presence, with many families conducting their own searches of public land. On 18th April 2022, a press release with an approximate strewn field was issued to local journalists. As with Winchcombe, there was significant national media interest, despite no stone being found to date. This helped us to gain access to search areas, as several landowers were aware of the meteorite before we contacted them.

The Adaptation of Online Project-Based Learning in Computer Engineering Education Settings

While many universities offered some online courses in computer engineering prior to the COVID-19 pandemic, few offered project-based courses in a fully virtual mode. This has changed with pandemic-related restrictions. When converting to an online-only mode, active-learning projects and lab components of computer engineering courses pose additional challenges because they require face-to-face interaction and specialized equipment. In this paper, we present how we adapted a year-long capstone course to be fully online at a public university in California, U.S., and report our findings based on students’ perceptions. Our major findings are: 1) students’ satisfaction rates of online courses improved over the one year of online-only learning, and 2) students tended to prefer synchronous lectures, but the difference in preference between synchronous vs. asynchronous teaching was not significant. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Primary care practitioners have a high level of satisfaction with the current breast referral pathway but the majority would support a change to patient self-referral

Aim: Currently, patients must consult with a primary care practitioner (PCP) prior to being referred to secondary care breast services. A change to patient self-referral would arguably reduce primary care workload, improve access for patients, and allow breast units to allocate resources more appropriately;no data currently supports this. This study aims to explore PCP's views on breast referral, evaluate the community breast workload, and to investigate the impact of COVID-19 on referral rates. Method: An electronic survey was designed on SurveyMonkey.com which aimed to collect both quantitative and qualitative data. The weblink to the survey was sent out via two electronic newsletters. Participants were asked: their role and gender, their level of confidence surrounding breast care, details surrounding their breast workload, how they felt COVID-19 had affected their referral rates, their level of satisfaction with the current pathway, and their opinions on a potential change to patient self-referral. Results: 79 responses were received. PCPs estimated that 7.0% (median) of their total consultations were regarding a breast-related issue and that COVID-19 had not had a significant impact on the rate of referral to breast units (P=0.75). 84.8% of PCPs were satisfied with the current referral pathway. Whilst 74.5% felt a change to patient self-referral would benefit patients and primary care services, their free text comments highlighted some of their reservations. Conclusions: PCPs have a high level of satisfaction with the current breast referral pathway, but the majority would be open to a change to patient self-referral to specialist breast units.

Preexisting autoantibodies to type I IFNs underlie critical COVID-19 pneumonia in patients with APS-1

Patients with biallelic loss-of-function variants of AIRE suffer from autoimmune polyendocrine syndrome type-1 (APS-1) and produce a broad range of autoantibodies (auto-Abs), including circulating auto-Abs neutralizing most type I interferons (IFNs). These auto-Abs were recently reported to account for at least 10% of cases of life-threatening COVID-19 pneumonia in the general population. We report 22 APS-1 patients from 21 kindreds in seven countries, aged between 8 and 48 yr and infected with SARS-CoV-2 since February 2020. The 21 patients tested had auto-Abs neutralizing IFN-a subtypes and/or IFN-;one had anti-IFN-beta and another anti-IFN-T, but none had anti-IFN-. Strikingly, 19 patients (86%) were hospitalized for COVID-19 pneumonia, including 15 (68%) admitted to an intensive care unit, 11 (50%) who required mechanical ventilation, and four (18%) who died. Ambulatory disease in three patients (14%) was possibly accounted for by prior or early specific interventions. Preexisting auto-Abs neutralizing type I IFNs in APS-1 patients confer a very high risk of life-threatening COVID-19 pneumonia at any age.
