Diets high in ultra-processed foods (UPFs) are associated with adverse health(1,2). In the UK and US, UPFs account for almost 60% of total energy intake(3). The NOVA system(4) classifies foods based on extent of processing but does not capture features that may underlie health associations. Proposed mechanisms include certain additives(5), unnaturally high sensory appeal or ‘hyper-palatability’(6), and food matrix disruption that increases the rate of energy intake (EIR)(7). There is an urgent need for a practical tool that characterises processing features relevant to health; to guide consumers in making healthier food choices. The aim of this study was to develop the novel ZOE Processed Food (ZPF) Risk Scale, based on processing features relevant to health, and to examine its associations with cardiometabolic outcomes.
Processing features included in the ZPF scale were additives and non-culinary ingredients (number and grading); hyper-palatability (true/false); and EIR (high ≥72kcal/min; low <72kcal/min)(8). Processed foods (whole foods excluded) were categorised into four classes, from ZPF1 (best) to ZPF4 (worst). Cross-sectional data from 550 US participants in the ZOE PREDICT 2 study (NCT03983733), were used to explore associations between mean daily energy intake (%EI) from ZPF1–4 and NOVA UPF categories (weighed food diaries) and anthropometry and blood biomarkers, using multivariable linear regression adjusted for age, sex, education, ethnicity, total energy intake, and diet quality (Healthy Eating Index), with false discovery rate correction (q<0.05).
Participants (74% female, mean±SD age 43.4±11.6y; BMI 25.8±5.2kg/m2) consumed 23.1%, 17.4%, 23.5%, and 17.5% of energy from ZPF1–4 respectively, compared with 38.4% from UPFs (NOVA). The proportion of unique logged foods (n=13,847) classified as UPF was 11.0%, 38.9%, 63.4%, and 72.5%, from ZPF1–4 respectively. Processed foods within food groups were distributed across ZPF classes (e.g. breakfast cereals (n=186); ZPF1-4, 18.8%, 45.2%, 19.9% and 16.1% respectively) compared to NOVA (UPF=78.5%). Higher %EI from ZPF4 was significantly associated with higher BMI (β=0.07kg/m2, q<0.001), weight (β=0.17kg, q=0.005), and glycA (inflammatory marker) (β=0.001μmol/L, q=0.003), whereas higher %EI from ZPF1 predicted lower BMI (β= −0.07kg/m2, q=0.001), weight (β= −0.14kg, q=0.022), and glycA (β= −0.002μmol/L, q=0.001).
The ZOE Processed Food Risk Scale captures specific processing features driving associations with health, providing a more precise and less stigmatising classification than NOVA. By distinguishing harmful from benign or potentially beneficial processed foods, the ZPF scale provides an evidence-based tool to inform consumer education, public health policy, and nutrition research.
We report the design and functionality of the Murchison Widefield Array Particle Detector Array (MWA PDA), an array of eight particle scintillation detectors deployed to Inyarrimanha Ilgari Bundara, the Murchison Radio-astronomy Observatory (MRO). The purpose of the instrument is to identify cosmic ray extensive air showers (EAS) occurring over the core of the MWA radio telescope and generate a trigger to allow radio data on the event to be captured and analysed. The system also acts as a pathfinder for a much larger instrument to be deployed in the core of the low-frequency component of the Square Kilometre Array, SKA-Low, by the SKA’s ultra-high-energy particles science working group. Here, we describe the instrument and associated infrastructure, which has been verified to comply with the strict radio-frequency emissions requirements of the MRO, and was deployed in November 2024. We present calibration data, which demonstrates the ability of each detector to identify individual atmospheric muons at the expected rate, and we characterise the temperature dependence of the system. We describe a sample of 35 500 EAS identified using multi-detector coincidence over a 13-d period, and show how the detector data can be used to reconstruct the arrival directions and approximate energies of these events. We conclude that the particle detector array can reliably trigger on and reconstruct EAS contained within the $\sim$$103 \times 90$ m$^2$ core region, arriving within 20$^{\circ}$ of zenith, at primary cosmic ray energies above $\sim$4 PeV. We have also verified that the detector array can generate triggers, allowing the capture of radio data from the MWA correlator for offline analysis.
This book provocatively argues that much of what English writers of the seventeenth, eighteenth, and nineteenth centuries remembered about medieval English geography, history, religion, and literature, they remembered by means of medieval and modern Scandinavia. These memories, in turn, figure in something even broader. Protestant and fundamentally monarchical, the Nordic countries constituted a politically kindred spirit in contrast with France, Italy, and Spain. Along with the so-called Celtic fringe and overseas colonies, Scandinavia became one of the external reference points for the forging of the United Kingdom. Subject to the continual refashioning of memory, the region became at once an image of Britain’s noble past and an affirmation of its current global status, rendering trips there rides on a time machine. The book’s approach to the Anglo-Scandinavian past addresses the specific impact of Nordic materials in framing conceptions of the English Middle Ages and positions the literature of medievalism less as the cause of modern Anglo-Nordic interests than as the recurrence of the same cultural concerns that animated early modern politics, science, and natural history. Emphasising multilingual non-literary traditions (such as travel writing and ethnography) and following four topics – natural history, ethnography, moral character, and literature – the focus of Northern Memories is on how texts, with or without any direct connections to one another, reproduced shared tropes and outlooks and on how this reproduction cumulatively furthered large cultural ideas.
By the Anglo-Scandinavian heuristic, travelling in Scandinavia could serve as a virtual trip through time. The region was necessary, familiar, and even, at times, charming. Yet it was the past: what Britain had been and, in an increasingly evolutionary outlook on human experience, what Britain had moved far beyond. Almost like a folk museum, the Nordic region was a place where travellers could talk with people in period costumes, eat period foods, watch period handicrafts being made, buy souvenirs, and walk through a carefully preserved period landscape. The region was necessary, familiar, and even, at times, charming. Yet it was the past: what Britain had been and, in an increasingly stratified view of human experience (Evolutionary Time, according to Johannes Fabian) what Britain had moved far beyond. Clothing, religion, lifestyle, occupations, buildings, personal habits, food – all of these therefore had authentic and immediate interest as what might be called tropes of tactile historiography, potentially revealing something about moral character, whether that of the current Nordic peoples or of the Britons imagined to have evolved from them.
Early modern discussions of British ethnographic history turn on a recurring set of references to Asia, migration, tribal unity, ancestral peoples, pagan practices, genealogies, violence, language, Christianity, mythology, and the Norman Conquest. Produced across the centuries I consider and circulated by writers who often had no direct influence on or even knowledge of one another, these tropes enable memories of a past that supports a specific socio-political present. They offer ways to think about the Nordic regions, Britain, and the historiographic connections among them that sustained national identity by means of historical division. At issue in such cultural memories is the establishment of some kind of continuity between past and present, which depends on distinctions between the two historical moments. Emerging from many early modern discussions of England’s political history was the belief that the Nordic and English peoples were of the same race and that as such they were categorically distinct from other races, especially from the French and sometimes even from the German ones. Evidence for this unity could be found in population movements and the attendant historical interactions, religious practices, and social characteristics.
Focused on the historical relations between English and the Nordic languages and on the relevance of Nordic literature to British experience, memories produced by language and literature worked towards this same end of fashioning a medieval memory. Lacking the mythology of the Poetic Edda and Prose Edda, as well as the sagas’ detailed descriptions of daily life in the Middle Ages, English readers could find in Norse literature reasons to believe there had been comparable material in English literary history and that what Norse literature described equally might have been said about the English experience. Similarities between Old English and Old Norse likewise could be understood to affirm the essential sameness of those who spoke the languages. With the theoretical underpinning of Herder’s and von Humboldt’s reflections on social identity, the putatively shared language and literature identified in this way became much more than a scholarly diversion. Like tropes of travel, ethnicity, and personal identity, replicated references to sagas, Eddas, speakers, poets, verse forms, translation, unintelligibility, dialects, and languages (medieval and modern) fashioned a historical identity worth remembering for what it revealed about the modern world and for how it illustrated contemporary divergences from its historical origins.
Three focuses of British travel writing from the seventeenth, eighteenth, and nineteenth centuries were natural history, science, and recreation. Throughout this period and often independently of one another, widely separated writers on these topics utilised a set of consistent yet contradictory images to represent their experiences. In explicit detail they described beauty but also filth, and dangers to which they responded with expressions of awe, uncertainty, and disgust. From these contradictions emerge coherent ways to look at the modern world – especially the contrasts between Britain and Scandinavia – as well as to remember the world from which it developed. The collective impact of replicated tropes rendered visits to the modern-day Nordic regions as rides on a time machine to the British medieval past.
Northern Memories concerns how English writers of the seventeenth, eighteenth, and nineteenth centuries remembered Scandinavia, especially Iceland and Norway; how by remembering Scandinavia and its people they furthered contemporary sentiments not simply about that region but about the emerging global role of Great Britain; and how they often did so by selectively collapsing the contemporary world and the Middle Ages, providing memories of both in the process. More than simply a literary issue, the construction of an Anglo-Scandinavian ethnicity served as an organising principle for cultural politics, providing ways to read past and present alike as testaments to British exceptionalism. Much of what English critics of the seventeenth, eighteenth, and nineteenth centuries remembered about medieval English geography, history, religion, and literature, they remembered by means of Iceland, Norway, Denmark, and Sweden. As British visitors and thinkers encountered the Scandinavian ‘present’ in the seventeenth, eighteenth, and nineteenth centuries, they similarly found evidence for the British past. Rather than a source study that traces the genealogy of cultural ideas, political contacts, or literary influences, this book is above all a theoretical inquiry about the persistence, independent imitation, and reproduction of Nordic tropes for the imagining of Britain and its medieval past.
Historical memory is situational, the result of a cultural process of construction and representation. As obviously ruinous, perverse, and even demonic as the Nazis’ methods and beliefs were, their use of Nordic imagery and ideas depends on many of the same kinds of historiographic manoeuvres and even some of the same tropes that are traced in this book. As much as the Nazis’ notions of world dominance differed from the aspirations of every English writer considered, both groups shared the strategy of incorporating a Nordic past in their cultural memories. What might be called a parallel descent from Germanic prehistory thus has unsettling epistemic implications. If memory is conditioned not only by what is being remembered but by who is doing the remembering, as many critics maintain, then the process itself – the tropes it uses and the fact that it combines them – is in some ways subject-neutral. It is such malleability and reproducibility that would allow for the creation of competing views from the same recirculated images – totalitarianism as well as fantasy. These may be the qualities that give historical memory its greatest power.
Overlapping galaxies, in which a foreground galaxy partially overlaps a background galaxy, offer a unique opportunity to measure dust attenuation, a key nuisance parameter in galaxy studies, empirically and in great detail by modelling the light of both the foreground and background galaxy and inferring the missing light in the overlapping region. However, the current catalogue of overlapping pairs is relatively limited in number compared to catalogues dedicated to individual galaxies. Expanding this catalogue is not only a necessity to facilitate further detailed dust studies beyond the few limited studies conducted thus far but also to improve pair-to-pair variance and support automated identification through machine learning techniques. To achieve this, we utilise galaxies classified as ‘overlapping’ from Galaxy Zoo DECaLS (GZD-1, -2, and -5), along with images from Data Release 10 (DR10) of the DESI Legacy Survey, in our individual citizen science project to classify these pairs directly using volunteers. This new catalogue will not only provide a wealth of targets for future dust studies but will also contribute to a deeper understanding of these pairs and dust as a whole.
In general, research demonstrates that deprivation, education, health, and well-being are determinants of volunteering, and that volunteering can play an important role in building stronger communities and provides many benefits for individual health and well-being. This study concentrates on the effects of physical and mental health and well-being as predictors when the aspect of socio-economic impact has been minimised. It utilises a unique data set from a UK Housing Association community with generally high levels of deprivation. Data were analysed using bivariate probit regression. In contrast to previous findings, physical health and mental health were not significantly related to volunteering. The key finding was that mental well-being was significantly related to informal volunteering.
An increasing number of children and adolescents are prescribed second-generation antipsychotic medications, which may lead to cardiometabolic or other physical health impairments. It is unknown whether lifestyle interventions can prevent or manage these adverse effects.
Aims
To evaluate the effectiveness of lifestyle interventions for preventing or managing cardiometabolic risks and other adverse physical health outcomes in this population.
Method
Four bibliographic databases were searched up to February 2024. Randomised controlled trials reporting a physical health outcome of children or adolescents (aged 6–17 years) taking antipsychotics and participating in a lifestyle intervention compared with treatment as usual (TAU) were eligible for inclusion. The Cochrane Risk of Bias 2 tool was used to assess risk of bias. Data were synthesised via a random-effects meta-analysis and narrative synthesis.
Results
Four studies with a total of 370 participants were included. Most (75%) had a high risk of bias. Lifestyle interventions resulted in moderate but statistically non-significant reductions in participants’ body mass index (standard mean difference −0.70, 95% CI: −1.70 to 0.31) compared with TAU. Some studies reported improvements in other physical health outcomes favouring the intervention, although findings were inconsistent and varied across different measures. Reporting of secondary indicators of physical health, including participant or family health behaviours, was limited.
Conclusions
The effectiveness of lifestyle interventions for preventing or managing the cardiometabolic risk and other adverse physical health outcomes in this population is unclear due to the limited number of available trials, small samples and high risk of bias. Larger trials are needed.
Tell settlements often provide a unique window into prehistoric lifeways due to remarkable preservation and safeguarding from modern disturbances. Vésztő-Mágor in Hungary is one such tell with stratigraphy, features and finds that reflect thousands of years of prehistoric settlement. In 2021, the Vésztő-Mágor Conservation and Exhibition Program began the work of stabilizing, documenting and preserving prehistoric deposits, features and artefacts exposed in an in situ exhibition trench at Vésztő-Mágor. In the process, an exceptionally well-preserved carbonized item was discovered embedded in a series of Middle Bronze Age house floors. We describe the object and context of discovery, and interpret it as matting inside a wattle-and-daub house. We expand our discussion to similar contexts known from Vésztő-Mágor, in the Carpathian Basin, and beyond, to highlight the technologies involving organic materials used at prehistoric tell sites and their significance for understanding lifeways at these settlements.
