Hundreds of large stone vessels can be found dispersed across the Xieng Khouang Plateau in northern Laos. Despite nearly a century of research, their purpose remains uncertain.

Here, the authors report on the excavation of the exceptionally large Jar 1 at Site 75, which contains a collective mortuary assemblage of secondary interments. The disarticulated remains of at least 37 individuals hint at the jars’ function within a complex funerary sequence, with direct radiocarbon dating indicating a prolonged period of mortuary activity c. cal AD 890–1160, which was a time of increasing regional interaction and mobility in Southeast Asia.

Myopia is an increasing global health concern and a leading cause of visual impairment. Genetic factors play a major role, and polygenic risk scores (PRSs) may help identify children at high risk of developing myopia. However, most PRSs are based on European populations, and accurately predicting risk across ancestries remains a challenge. We developed and evaluated PRSs for spherical equivalent refractive error (SER) and myopia using multitrait and multi‑ancestry genomewide association study data. A multitrait analysis of SER‑correlated traits identified 709 genomewide significant loci. PRSs were generated with SBayesRC for each ancestry group and for a combined multi‑ancestry model, and validated in the Australian Twins Eye Study and non‑European participants from the UK Biobank. The European PRSs explained approximately 20% of SER variance in Europeans and 18% in admixed Europeans and showed good transferability to South Asian (14%), East Asian (13%), and African (8%) groups. A multi‑ancestry PRS further improved prediction in Africans, explaining 9% of the variance. Predictive accuracy for high myopia was strong in the admixed group (AUC = 0.82, 95% CI [0.78, 0.87]), with all ancestry groups achieving AUCs of at least 0.70; European ancestry data were not available. PRS also predicted axial length in children, particularly those aged 5–8 years, where individuals in the lowest 10% of the PRS distribution had significantly longer axial lengths (β = 0.81 mm, p = 5.71 × 10−3). These findings enhance genetic prediction of SER and myopia, showing the potential of multitrait, multi-ancestry PRS for early, equitable risk stratification.

This article proposes the examination of the climate politics of labour unions, particularly the strategy of just transition, through the prism of environmental labour studies, an ecosocial approach to labour environmentalism. In the first part, it presents a historical overview in order to highlight how the just energy transition became a central element of labour environmentalism. The paper then examines the double impact of climate politics and just transition on labour environmentalism – narrowing its substantive focus while deepening the intersection of nature and labour within and beyond the workplace. The second part draws on the environmental labour studies approach to propose that labour environmentalism should take into account the inseparable relationship between labour and nature, expand the scope of work and workers, and account for global divisions of labour. In our view, such a programmatic shift will ensure that work and workers are placed centrally within ecosocial politics.

A second-occurrence (SO) focus is the semantic focus of a focus-sensitive operator (e.g. only), but is a repeat of an earlier focused occurrence. We report on the first systematic production and perception experiments to show that SO foci occurring after a nuclear accent are, as Rooth (1996b) has claimed, prosodically marked. We find that (i) there is no mean pitch rise on SO foci, (ii) SO foci are marked by longer duration and greater energy, and (iii) listeners are able to detect the difference between SO foci and nonfoci. On the basis of these results, we argue that SO focus is compatible with theories of focus interpretation that it has been claimed to contradict.

The Radio Neutrino Observatory-Greenland (RNO-G, at Summit Station) experiment comprises an extensive fat-dipole antenna array deployed into ice boreholes over an eventual area of approximately 35 km2. Since the RNO-G experimental sensitivity depends on the radio-frequency properties of the firn, which are known to vary laterally on sub-km distance scales and vertically on sub-meter distance scales, a technique for quickly extracting information on firn ice properties with depth ($n(z)$) during drilling and deployment is desirable. Given that a dipole’s resonant wavelength is fixed by geometry, the resonant frequency $f_{res}$ (measured as an S-parameter reflection coefficient [‘$S_{11}$’] minimum) scales inversely with the local refractive index, allowing a translation of a depth-dependent $S_{11}$(z) profile into $n(z)$. $S_{11}$(z) data were initially taken in August 2024 using a dipole lowered into a newly drilled 98 ± 1 mm diameter, 350 m deep borehole at Summit Station, Greenland, approximately 1 km from the site of the original GISP-2 core; improved measurements were subsequently made in May 2025. We conclude that $S_{11}$(z) data can be used to estimate $n(z)$, on 50 cm vertical scales, at the per cent level of accuracy required by experiments such as RN0-G.

As far as the composition of the House of Commons is concerned the 2001 British general election was a rerun of its 1997 predecessor. Labour won 413 seats, almost two-thirds of the total, and their 167 seat majority represents only a marginal change in the 179 seat majority they achieved in 1997. The hapless Conservatives had a net gain of only one seat and they remain as far from government as ever with only 161 seats in the House overall. The Liberal Democrats picked up a useful additional six seats and now have their largest representation in the House of Commons since the 1920s. With very minor changes in the representation of other parties, the 2001 House of Commons looks a lot like the 1997 House of Commons, as can be seen in Table 1 .

In one crucially important respect, however, the 2001 election was very different from its predecessor.
