Concordia Station is a long-term lidar observatory in Antarctica. Its main purpose is to detect and classify polar stratospheric clouds (PSCs). In September 2023, water ice PSCs were observed for a period of 6 days. This has never occurred during the month of September in the 10 years of observations of PSCs at Concordia Station. In addition, the space-borne CALIOP (Cloud Aerosol Lidar with Orthogonal Polarization) lidar observed a rare occurrence of ice PSCs over Concordia Station during the first half of June. It is well known that the January 2022 eruption of the Hunga submarine volcano (20°32’S, 175°23’W) injected vast amounts of water vapour into the stratosphere. The Hunga hydration flooded southern high latitudes at the end of the 2022 austral winter, and the moist air was then entrained into the developing vortex in the austral autumn (April–May) of 2023. The increased water vapour from Hunga was reported to promote PSC formation by cooling the stratosphere and raising PSC formation temperatures. Here, we explore the impact of the Hunga eruption on the PSCs observed at Concordia Station.

We study large deviations for Cox–Ingersoll–Ross processes with small noise and state-dependent fast switching via associated Hamilton–Jacobi–Bellman equations. As time scales separate, when the noise goes to 0 and the rate of switching goes to $\infty$, we get a limit equation characterized by the averaging principle. Moreover, we prove the large deviation principle with an action-integral form rate function to describe the asymptotic behavior of such systems. The new ingredient is establishing the comparison principle in the singular context. The proof is carried out using the nonlinear semigroup method from Feng and Kurtz’s book [14].

This review examines the role glycerophospholipids (PL) in dairy cow health, with specific focus on phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI) and phosphatidylserine (PS). Increasing parity of cows is associated with lower concentrations of plasma PL that contain very long-chain omega-3 fatty acids, including docosahexaenoic acid and eicosapentaenoic acid, which are precursors for prostaglandin synthesis, and have anti-inflammatory roles. Low concentrations of these PL could plausibly contribute to the increased risk of disease, reproductive failure and mortality in older cows. The bioavailability and metabolism of fatty acids may differ among supplements that are predominately neutral lipids, such as triacylglycerol-rich oils, and those bound to PL including pasture, whole or ground oilseeds and fish meal. Hepatic lipidosis can occur during the transition period if there is insufficient very-low density lipoproteins (VLDL) production in the liver to transport lipids into blood circulation. The PC are the primary PL of VLDL and are produced by two main pathways in the liver, the cytidine diphosphate-choline pathway that uses choline as a substrate, and the PE N-methyltransferase pathway that uses PE and methyl-donors as substrates. Co-supplementation strategies that target both pathways may increase PC production over a one-pathway supplementation strategy. The PIs are phosphoinositides precursors, which have broad physiological roles including regulating inflammatory processes and may offer targets for novel treatment and management of disease. Both the PI and PE are precursors to endocannabinoids, important regulators of energy metabolism, immune function and reproduction in mammals. Early findings on the endocannabinoid system in transition dairy cows yielded results that diverge from non-ruminant models. The PS expression on cytoplasmic membranes signals apoptosis, coagulation and contributes to sperm–oocyte recognition. As lipidomic diagnostics become increasingly available, understanding the metabolism of PL will continue to develop and promises to offer novel strategies for optimising cattle health and longevity.

The UK National Institute for Health and Care Excellence (NICE) recommends CBT for people with psychosis, yet many do not access therapies promptly, and duration of untreated psychosis predicts poorer outcomes. In addition to systemic service issues, it is likely that insecure attachment, common in people with psychosis, constitutes a key barrier to therapy. If we can articulate attachment patterns in terms of interpersonal beliefs and behaviours, we will be better placed to engage people in CBT. We used a cross-sectional design to examine theoretically predicted relationships between attachment style and (1) beliefs about self and others, (2) underlying assumptions, and (3) help-seeking intentions, across the psychosis continuum – in analogue and clinical samples. We recruited a general population analogue sample with elevated levels of non-clinical paranoia (n=172) and a clinical sample with self-reported psychosis (n=130). All completed standardised measures of attachment, beliefs about self and others, underlying assumptions and help-seeking. Regression analyses showed that insecure attachment predicted higher levels of negative self- and other-beliefs, and problematic underlying assumptions, and reduced help-seeking intentions, with some differences in patterns across analogue and clinical samples. Attachment is associated with CBT treatment targets and can inform psychological formulation and treatment. Our measure of assumptions may have been inappropriate for the clinical group. We conclude with public health, service level, and clinical implications to improve engagement and outcomes in CBT for psychosis.

Key learning aims

1. (1) Everyone with psychosis should have access to recommended treatments including CBT, but many do not.

2. (2) Insecure attachment is common in people with established psychosis or elevated levels of non-clinical paranoia, and may be a key barrier to accessing therapy.

3. (3) We show that insecure attachment is associated with (1) beliefs about self and others, (2) underlying assumptions, and (3) help-seeking intentions.

4. (4) Attachment style can inform CBT formulation and intervention, and wider service level and public health campaigns designed to improve engagement and outcomes for people with or vulnerable to psychosis.

Laser weed control is an emerging non-chemical technology made feasible by recent advances in artificial intelligence and automation. This research evaluated the response of four turf and weed species to varying levels and patterns of laser intensity to determine practical applications of laser weeding in turfgrass systems. Field experiments were conducted from July 2024 to March 2025 on research fairways in Blacksburg, VA, using a 10 W diode laser in spiral patterns with varying pattern-averaged energy densities (PAED). Two studies were implemented: one evaluated increasing energy intensity, and the other assessed combinations of line spacing, PAED, and number of passes in a factorial design. Line spacing significantly influenced weed control efficacy, with 4-mm spacing improving green cover reduction by up to 10% over denser patterns at the same PAED. Bermudagrass [Cynodon dactylon (L.) Pers.] recovered fully within 24 days post-treatment, while creeping bentgrass (Agrostis stolonifera L.) showed prolonged injury at higher intensities and wider spacings. These results demonstrate that laser weeding is feasible in turfgrass systems, especially with optimized energy and pattern configurations, and highlight the need for pattern customization to balance weed control with turfgrass safety.

Vegans face a problem, at least if they base their arguments upon principles against causing harm. As Donald Bruckner (2020) has pointed out, these same principles risk ruling out a great many other practices – even eating dessert. Eating dessert risks being impermissible because of the crop deaths associated with agricultural practices, especially the use of insecticides and rodenticides. I suggest that the extent to which this problem emerges depends on the exact principle vegans appeal to. Under some principles against causing harm, the problem indeed stands. I suggest that the vegan has a couple of options for escaping this problem. She might appeal to a principle that doesn’t have such implications. Alternatively, she might simply bite the bullet and accept that morality really is much more demanding here than we might have thought. I’ll give some reasons why biting this bullet isn’t as bad an option as one might suppose.

Tech innovations have the potential to disrupt traditional banking by unbundling banking, money, and payments; however, their impact on the cross-border payments system (CBPS) – which still relies on correspondent banking (CoBanking) networks – remains uncertain. This uncertainty is compounded by the literature’s tendency to distinguish between cash clearing and credit and to focus on the latter. Challenging this distinction, the article offers a historical perspective on the role of credit in CoBanking and international payments. It reveals the deep-rooted importance of credit in the CBPS and highlights correspondent banks’ role in providing it. But deep-rooted does not mean static. Indeed, changes in bank-intermediated trade finance practices during and after WWI reshaped the London-based CoBanking network. Furthermore, cash clearing and credit operations remained remarkably congruent until at least the 1980s, as reflected in banks’ internal organisation, reporting, and contemporaries’ descriptions of the payment system. The article argues that adopting a definition of payment systems that integrates both cash clearing and credit is essential to understanding the history of CoBanking and how it supports the CBPS. It suggests that relying on tech firms to provide the elastic payments infrastructure the economy requires could equate to jumping out of the frying pan and into the fire.

Many mergers and acquisitions (M&As) fail, and an emerging body of literature highlights the role of prejudice in derailing the M&A process. While prejudice is frequently observed in M&As, strategies to mitigate these biases remain underexplored. Adopting a qualitative case study approach, this study focuses on Chinese acquisitions in the UK and examines how managers from both the acquired and acquiring organizations navigate prejudice through emotional sensemaking. The findings demonstrate that emotional sensemaking plays a critical role in shaping the post-acquisition integration (PAI) process and its outcomes. Specifically, sensemaking supported by emotional intelligence facilitates the accommodation or reduction of prejudice, while emotionally unintelligent sensemaking tends to reinforce it. By focusing on the dynamic, interactive emotional exchanges between managers at the micro level, this study offers a fresh lens on the integration process beyond traditional strategic or structural explanations. The study contributes to the literature by advancing the understanding of micro-level emotional sensemaking in the PAI, emphasizing the dynamic, interactive nature of emotional sensemaking between acquirer and acquiree managers, and its impact on the integration process and outcomes.

John V. Taylor was reluctant to acknowledge process theology flourishing in the 1960s; however, in reading a book by Norman Pittenger, God in Process, during a train ride, he had a ‘light bulb’ experience, triggering the writing of The Go-Between God in 1972. Though Taylor may not have studied the technicalities of the process philosophy of A. N. Whitehead and Charles Hartshorne, he drew upon their characteristic understanding of God. By contrast with Classical Theism’s contention that God is absolute in all respects, they vigorously argued that God is relative to the natural universe and revealed in and through its creative processes. Taylor was also influenced by the Australian biologist Charles Birch, a proponent of process theology. The shape of the train-ride religious experience, which Taylor unpacks in The Go-Between God, bears a remarkable family likeness to the kind of religious experience articulated at length by Whitehead in response to the atheism of Bertrand Russell and the logical positivism of A. J. Ayer, in his book Modes of Thought. This was published in 1938, the year of Taylor’s admission to Holy Orders. It may be that Taylor was unwittingly much more of a process theologian than he himself was aware.

Healthy seeds are an important component of global food security, and their microbiome was recently identified as crucial for plant growth, resilience and health. Seed vigour is highly affected by storage conditions and aging. To study the impact of seed aging on the Brassica napus seed bacterial community, we conducted accelerated aging tests (45°C, humidity > 95%) with seed lots of four genotypes originating from two field sites in Germany. We found a strong effect of accelerated aging on germination, seedling phenotypes, as well as the seed bacterial community. Control seeds developed mainly into normal seedlings and were characterized by diverse bacterial communities comprising typical core seed microbes. Accelerated aging resulted in abnormal germination and reduced total germination. Furthermore, accelerated aging reduced diversity and evenness of the seed bacterial community and contributed to a shift from Gram-negative to Gram-positive bacteria. This effect, especially the enrichment of Firmicutes, was found irrespective of the genotype and field site; however, the way stress affected bacterial taxa varied, depended on both factors. Tumebacillus and Bacillus showed a significant negative correlation with germination phenotype, whereas alpha diversity correlated positively with a high total germination. At the functional level, the majority of isolated bacteria demonstrated plant-beneficial characteristics, showing a greater beneficial potential in the aged seeds. Our results show that accelerated aging tests affect the seed bacterial community structure and diversity, and correlate with the presence of certain taxa, which might have an effect on germination and seedling phenotype.
