Sorgoleone, an allelochemical exuded from root hairs of grain sorghum [Sorghum bicolor (L.) Moench], has proven herbicidal activity on several weeds and crops. Due to its hydrophobic nature and affinity for organic matter, sorgoleone can persist in the soil for a long period. Although sorghum residues are beneficial for weed suppression, growers in the southeastern United States have raised concerns that these residues may negatively affect wheat (Triticum aestivum L.) emergence in double-crop systems. Two independent laboratory studies were conducted to evaluate sorgoleone activity: (1) weed species/wheat variety study, which included four weed species, Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot], large crabgrass [Digitaria sanguinalis (L.) Scop.], sicklepod [Senna obtusifolia (L.) Irwin & Barneby], and velvetleaf [Abutilon theophrasti Medik.], and two wheat varieties, ‘USG3251’ and ‘Shirley’; and (2) wheat variety and group study, which included a total of 20 varieties distributed in four wheat groups. In both studies, sorgoleone was applied at 0.025, 0.05, 0.10, 0.15, 0.20, and 0.30 g L−1 to seeds grown in petri dishes under laboratory conditions. In Study 1, sorgoleone activity had a stronger effect on grass weeds than on broadleaf weeds. Lolium perenne ssp. multiflorum was the most susceptible weed, showing 77% growth reduction at 0.3 g L−1 of sorgoleone. At the same concentration, D. sanguinalis showed the second-highest response, with a 32% growth reduction, followed by A. theophrasti and S. obtusifolia, with reductions of 23% and 20%, respectively. No effect of sorgoleone was observed on wheat varieties. In Study 2, growth reduction was only observed for six wheat varieties at the highest sorgoleone concentrations. Furthermore, in between group comparisons, Hard Red wheat presented higher response to sorgoleone. These findings demonstrate strong herbicidal activity of sorgoleone on grass weeds, particularly L. perenne ssp. multiflorum, while having minimal effects on most wheat varieties.
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a serious disease and increasingly prevalent in children. MASLD is associated with health consequences such as type 2 diabetes and CVD. While vitamin E is a potent antioxidant that has been proposed to improve liver function and cardiometabolic health including liver markers, lipid profile, glycaemic control and anthropometric measurements. A comprehensive search was conducted up to March 2025. Data on anthropometric measures, liver enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transferase (GGT)), glycaemic indices (fasting blood sugar (FBS), insulin, homeostatic model assessment for insulin resistance (HOMA-IR)), lipid profiles (total cholesterol (TC), TAG, LDL-cholesterol, HDL-cholesterol) and serum vitamin E levels were extracted. Statistical analyses were performed using a random-effects model. Eleven randomised controlled trials involving 665 participants were included in this study. Vitamin E significantly reduced ALT (weighted mean difference (WMD) = −5·23 U/L; 95 % CI: −7·72, −2·75; P < 0·001) and AST (WMD = −3·00 U/L; 95 % CI: −4·59, −1·41; P < 0·001), reflecting improved liver function. It also decreased TC (WMD = −5·77 mg/dl; 95 % CI: −11·46, −0·09; P = 0·04) and HOMA-IR (WMD = −0·82; 95 % CI: −1·28, −0·37; P < 0·001), while significantly increasing serum vitamin E levels (WMD = 9·16 mg/l; 95 % CI: 3·29, 15·03; P = 0·002). No significant changes were observed in the BMI, GGT, FBS, insulin, LDL-cholesterol, HDL-cholesterol or TAG levels. Vitamin E supplementation in paediatric MASLD appears to favourably influence key liver enzymes such as ALT, AST and certain metabolic factors including TC, and HOMA-IR levels, supporting its potential role as adjunctive therapy.
In Colombia, monitoring biodiversity studies is hindered due to logistical, economic and security issues due to armed conflict. This study aimed for the application of environmental DNA (eDNA) to monitor mammalian diversity following riparian outlets along the Colombian Pacific coast. Fieldwork was conducted during two different periods, August to November 2021 and February to May 2022. A total of five orders of terrestrial mammals were recorded, distributed in ten families and 17 species. The most abundant orders were Rodentia and Didelphimorphia, with a total of six and five species each. Our methodology can detect relevant and emblematic terrestrial species reported for the region with traditional methods, such as Chironectes minimus and Cabassous centralis, as well as species that had not been confirmed to occur in that area, like Speothos venaticus. Our results demonstrate the high potential for the development of the eDNA tool in Colombia for detection of vulnerable species and, in the future, supporting conservation processes.
The aim of this study was to examine the potential mediating role of intuitive eating in the relationship between food insecurity and adherence to the Mediterranean diet. A total of 1039 adults aged between 20 and 64 years living in Niğde, Türkiye, were evaluated using a questionnaire. The questionnaire included items on participants’ general characteristics, dietary habits, the Household Food Security Survey Module – Short Form, the Mediterranean Diet Adherence Screener and the Intuitive Eating Scale-2. Intuitive eating was found to play a partial mediating role in the relationship between food insecurity and adherence to the Mediterranean diet. Food insecurity was directly and negatively associated with adherence to the Mediterranean diet, and this association remained significant even after the inclusion of intuitive eating as a variable in the model. In conclusion, food insecurity was found to negatively affect adherence to the Mediterranean diet not only directly but also indirectly by weakening intuitive eating skills. Interventions aimed at promoting intuitive eating may help mitigate unhealthy dietary behaviours associated with food insecurity; however, improving food access and living conditions remains essential for a long-term solution.
Dairy cow longevity affects production economy, climate footprint, and cow welfare. Based on data from the Danish Cattle Database, this research paper evaluates the relationship between early-life risk factors associated with the period before first calving and cow longevity, including data from all Danish dairy cows culled in 2019–2023. Explanatory variables for linear mixed models included calf size, twinning, and age at first calving. Information about the length of productive life (LPL) (mean: 1,074 days) and lifetime milk yield (mean: 32,088 kg energy-corrected milk) was available for 767,305 and 716,120 cows, respectively. Milk yield per day of life increased from 7 kg in cows culled during the first lactation to more than 20 kg in cows culled in their fifth or later lactations. For cows born as singletons, LPL was one month longer for cows born as large calves than for medium-sized calves, and 2 months longer than for small calves. Cows born as twins had 2 to 3 months shorter productive lives compared to cows born as singletons. For singletons, lifetime milk yield was 1,200 kg higher for large calves than for medium-sized calves, and 2,100 kg higher than for small calves. Lifetime milk yield was 1,500 to 3,500 kg lower in cows born as twins. Cows being among the third quartile of age at first calving had an estimated productive life 2.5 months longer, and a lifetime milk yield more than 2,600 kg higher than cows calving among the first quartile of age. The results from this study clearly demonstrate the importance of ‘a good start’.
Snapmelon is an indigenous crop of Indian origin that has contributed resistance genes against major melon diseases. Despite its importance, Snapmelon is an under-utilized crop, and its cultivation may be limited due to its very short post-harvest life, fruit-bursting on maturity and very thin pericarp that is unsuitable for long-distance transportation. Studies on the inheritance of melon fruit bursting are scanty, and according to the available literature, it is due to complementary gene action. The inheritance of fruit bursting in Snapmelon in our work was studied through an inter-botanical cross between Snapmelon (IC632170, bursting fruit type) and Chandalak melon (Kashi Madhu, non-bursting fruit type). F2 and backcross populations were developed, and all three populations were evaluated for fruit bursting under polyhouse conditions for two seasons. Chi-square analysis indicated non-significant deviations from the expected 3:1 Mendelian ratio for non-bursting: bursting type fruits in the F2 population, suggesting the monogenic control of fruit bursting. The backcross with parent Kashi Madhu exhibited 1:0 (non-bursting: bursting) ratios, while the backcross with parent IC632170 revealed 1:1 (non-bursting: bursting) ratio. Selective genotyping in the F2:3 population of Kashi Madhu x IC632170 using 86 polymorphic Simple sequence repeat (SSR) markers revealed the association of the marker CMCT505 for fruit bursting at maturity. Knowledge on the genetic basis of fruit bursting is crucial for designing effective breeding strategies aimed at developing non-bursting Snapmelon varieties suitable for commercial cultivation and improved post-harvest handling.
During a biodiversity survey conducted in the Gulf of Izmit (Sea of Marmara, Türkiye), 87 individuals of bat star Asterina stellifera, whose native distribution is along the South Atlantic coasts of South America and Africa, were identified. The population seems to be well adapted to a mixed substrate composed of coarse sand, silt, and shell fragments of Mytilus galloprovincialis between 4 and 8 meters of depth range. DNA barcoding of the mitochondrial cytochrome c oxidase subunit I (COI) gene showed over 99% identity with the National Center for Biotechnology Information (NCBI) GenBank sequences from South America, indicating the possible origin and shipping as the mode of introduction. This is the first record of this species outside of its native range.
There is scant information about seed germination and seedling emergence of common evening primrose (Oenothera biennis L.), even though it is a common and widespread weed in North America. This study was conducted to determine the influence of several environmental factors on its seed germination and seedling emergence from three North American populations in autumn. In alternating light (12 h)/darkness (12 h), maximum germination (89.7% to 97.7%) of freshly matured seeds occurred at alternating temperature regimes ≥25/15 C, and germination was lowest (0% to 80.3%) at the coolest temperature regime of 15/5 C. In comparison to seeds incubated with an alternating light/dark photoperiod, germination was lower when seeds were exposed to continuous darkness, indicating that seeds were positively photoblastic. Cold stratification at 4 C enhanced germination, with seed dormancy alleviated after 4 to 8 wk, depending on the study population. For freshly matured seeds, germination exceeded 67% in test solutions ranging from pH 3 to 10, and was highest (80% to 100%) at neutral or near-neutral pH. Germination exceeded 84% in solutions with osmotic potentials ranging from 0 to −0.4 MPa, and germination was observed at osmotic potentials as low as −0.8 to −1.0 MPa, depending on the study population. Seedling emergence was only observed for seeds sown on the surface of soil or buried to depths ≤2 cm. Thus, seeds of O. biennis are positively photoblastic and exhibit germination characteristics associated with type 2 non–deep physiological dormancy at maturity, with seeds being capable of germinating under a variety of climatic and edaphic conditions.
To examine policy processes and industry opposition surrounding the first US healthy checkout ordinances (HCO), which mandate nutritional standards for foods and beverages displayed in grocery checkout areas.
Design:
Qualitative case study comparison using Kingdon’s Multiple Streams Framework, triangulating city records, advocacy materials and key informant interviews.
Setting:
Local governments of Berkeley and Perris, California, USA.
Participants:
Informants, identified from documents and snowball sampling, included community-based organisation members/local advocates (Berkeley n 6; Perris n 1), staff from national nongovernmental organisations providing assistance (Berkeley n 2; Perris n 2), city councilmembers (Berkeley n 2; Perris n 2), city commissioner (Berkeley n 1) and city staff (Perris n 2).
Results:
We described and compared each city’s HCO enactment process. In both, prior commitments to community-led food environment reforms enabled advocates to garner financial and technical support for early coalition building. Berkeley used soda tax proceeds for a youth-led citizen science project to formulate an enforceable HCO and assess public support. These experiences fostered political commitment to define applicable stores, checkout areas and nutritional standards. Campaigns emphasised protecting children and parents from predatory marketing and impulse buying. Berkeley’s campaign quietly and cautiously engaged mostly independent retailers, attracting limited industry attention; Perris engaged all retailers and after enactment faced open opposition from a chain store and trade associations. Perris’ amended HCO included concessions allowing unhealthy items at many endcaps and long checkout lanes.
Conclusions:
HCO enactment may be facilitated by prior food policy experience, community capacity, early coalition building, careful policy design and framing and anticipating and managing industry opposition.
In tropical forests, the relative thermal and climatic stability contrasts with the seasonal oscillations, mainly due to rainfall patterns, that structure life cycles in temperate zones, leading to different ecological strategies among species. This study investigates the seasonal activity patterns and size-abundance relationships of four sympatric Goliath beetle species (Goliathus goliatus, Mecynorhina confluens, Mecynorrhinella poggei, and Fornasinius russus) in the Mabira Forest Reserve and in other forest areas, Uganda. Over three years (2021–2023), 1,231 individuals were sampled monthly using standardised traps and random transects. Time series analyses were used to explore patterns of abundance. We found a significant negative correlation between body size and abundance (r = –0.78, P < 0.05), with the smaller species, M. confluens and F. russus, being most numerous. Time series and Analysis of Variance (ANOVA) revealed significant sinusoidal patterns of seasonality for G. goliatus, M. poggei, and F. russus, while M. confluens showed non-significant cyclical trends, indicating potential stochastic fluctuations or greater ecological flexibility. Seasonal peaks were species-specific and generally occurred during transitional periods between wet and dry seasons, diverging from previously reported insect patterns peaking during the wet season. These findings suggest that differing phenological strategies may facilitate coexistence and niche partitioning, particularly among species differing in body size. Furthermore, larger species appeared to emerge earlier in the year, possibly reflecting life history adaptations or competitive dynamics. Our study highlights the importance of long-term, species-specific monitoring to understand ecological roles and vulnerabilities of tropical beetles, especially large-bodied taxa increasingly threatened by habitat loss and climate variability. Such insights are essential for informing conservation strategies in biodiverse tropical ecosystems.
The objective of the study was to evaluate the fermentation characteristics, losses, aerobic stability and nutritive value of the silage of three cultivars of cactus pear {‘Orelha de Elefante Mexicana’ – OEM (Opuntia sp.), ‘IPA Sertânia’ and ‘Miúda’ [Nopalea cochenillifera (L.) Salm Dyck.]} mixed with three levels of inclusion of Leucaena [Leucaena leucocephala (Lam.) de Wit] hay (0, 15 and 30%). The design was completely randomized in a 3 × 3 factorial arrangement, corresponding to cactus pear varieties and Leucaena hay levels, with four replications. Gas and effluent losses, pH, organic acids, aerobic stability and nutritional value of silages were evaluated. The silages of the cultivar OEM without the inclusion of Leucaena hay had a higher pH (4.95) compared to Miúda (4.11) and IPA Sertânia (4.17). The aerobic stability was maintained for more than 60h after opening the silos. The inclusion of Leucaena hay (up to 30%) increased the pH and reduced losses by effluents without compromising the fermentative characteristics of the silages, indicated by the predominance of lactic acid (93 g/kg).
Recent geopolitical events remind us of the need for a resilient, global approach to sustainability science. This Commentary argues that a diverse, bottom-up approach is essential to ensure sustainability science progresses, even amid shifting political processes that threaten international collaboration and funding. Locally driven solutions that value diverse perspectives and knowledge systems are vital for resilience. By supporting community-led action, sharing ideas across regions, and recognising that sustainability means different things in different places, we can build a more flexible, inclusive, and resilient path toward achieving the Sustainable Development Goals in an uncertain world.
Technical summary
Recent geopolitical events provide a stark reminder of the need to build a resilient, global approach to sustainability science. Centralised, top-down models of sustainability science are likely to be vulnerable to disruptions, from pandemics to wars, that threaten progress towards the Sustainable Development Goals and jeopardise decades of collaborative advancement that are needed to support future progress. We argue that a decentralised, community-empowered model provides the foundation needed for a resilient sustainability scientific effort. By prioritising local solutions, embracing diverse knowledge systems, and fostering horizontal knowledge exchange, we can create a more resilient and adaptable framework. Sustainability science initiatives need to elevate successful local initiatives, adopt transdisciplinary approaches that include underrepresented knowledge holders, build decentralised knowledge-sharing networks, and recognise that sustainability has different meanings across cultural and geographical contexts.

The Earth is approaching irreversible tipping points. Markets, democracy, and technology alone cannot address these complex crises. Future Design (FD) tackles these challenges by activating human ability to prioritise future generations’ happiness over immediate gains. This research expands the FD framework and reviews a decade’s worth of studies, deepening our understanding of FD’s potential in creating mechanisms for long-term societal well-being and environmental sustainability.
Technical summary
The Earth is approaching irreversible tipping points across multiple domains. Despite advances in markets, democracy, and science, these systems systematically fail to prioritise future generations’ well-being – creating what we term ‘future failures’. New mechanisms are needed, such as FD. Originating in Japan in the early 2010s, FD aims to design, experiment with, and implement mechanisms that activate our futurability – the ability to prioritise the happiness of future generations over immediate gains – to tackle future failures. This paper introduces presentability and pastability alongside futurability, extending the FD framework. Placing various FD studies from the past decade within this framework, this study reviews mechanisms for activating these abilities and examines how activating one ability affects the others. These abilities are ‘leverage points’, as defined by Meadows. We explore the path to a paradigm shift by designing and using mechanisms that activate these points. This paper also highlights unknowns about FD and potential directions for its development, providing a comprehensive overview of its current state and future prospects in addressing global challenges.

Schistosomiasis remains a significant public health concern in sub-Saharan Africa, particularly among women and children. In Cameroon, urogenital and intestinal schistosomiasis affect the lives of millions of impoverished populations, and female genital schistosomiasis (FGS) remains a serious threat which has not been quantified explicitly. The extent of stigmatization and discrimination related to FGS is currently unknown. This study explores the use of precision mapping to identify high-risk communities for urogenital schistosomiasis and guide targeted screening for FGS. Parasitological surveys were conducted between November 2020 and July 2021 in four health districts using urine filtration and Kato-Katz techniques, first in schools to identify areas of higher transmission, and secondly in selected high-risk communities. Geographic information system tools were employed to identify high transmission foci and households of targeted infected women. Results of surveys in schools showed no schistosomiasis transmission in Ayos (0%) and low prevalence in Akonolinga (8%), while Bertoua and Doume had high prevalence, up to 33% and 48% infection with Schistosoma haematobium, respectively. These results made the two health districts of Bertoua and Doume suitable for focused FGS investigations. Surveys in communities revealed higher schistosomiasis prevalence and infection intensity in Doume compared to Bertoua. Precision mapping effectively identified infected women and enabled targeted recruitment for further clinical studies, facilitating efficient resource allocation for gynaecological follow-up. This approach demonstrates the value of geospatial tools in enhancing targeted public health interventions, disease surveillance and control strategies.
