Newborn mice given too much food later developed more severe muscle loss, metabolic problems and shorter lifespans than control mice. Persistent changes in the gut mucus barrier and a decline in the bacterium Akkermansia muciniphila were linked to these effects.
A computer-based analysis of sauropod thigh bones suggests that the largest dinosaurs did not all use the same mechanical design to support their weight. Differences in bone shape, internal architecture and joint cartilage were linked to how the bones handled stress and stiffness.
Researchers developed a propylene-carbonate electrolyte that helped a 1-ampere-hour lithium-ion pouch cell operate from −50 to 120°C. The cell remained stable for 2,000 cycles, with an initial charge efficiency of 93.5%.
Researchers have realized an optical clock based on a nuclear transition in thorium-229, using a laser stabilized to radiation absorbed by thorium nuclei in a calcium fluoride crystal. The clock was also used to search for periodic changes and slow drifts that could indicate interactions between ultralight dark matter and fundamental forces.
Researchers used changes in the upper atmosphere recorded by distant ground stations to estimate vertical movements caused by the magnitude 7.7 Myanmar earthquake. Three distinct signal peaks helped identify the locations and relative strengths of acoustic waves linked to uplift along the fault.
A review of 1,903 studies examined how artificial intelligence is being used to assess and manage supply-chain risks. The 54 studies selected for detailed analysis point to stronger risk prediction from machine-learning models, while also highlighting continuing concerns about data quality and how clearly these systems explain their decisions.
Native verge gardens were more common over time near other verge gardens in two Perth-area communities, a study found. Adoption rates were 11% in Claremont and 18% in Daglish, and many conversions took place without government support.
School professionals in Türkiye said they often recognised possible online grooming or sexual exploitation through changes in students’ behaviour, but were unsure about legal reporting duties and referral routes. The study argues that technical safeguards need to be combined with clear procedures, staff training and ongoing work with families.
Underused materials such as fruit and vegetable residues, cereal by-products, legume components and spent coffee grounds could add fiber, protein, antioxidants and micronutrients to bakery products, according to a narrative review. The review also highlights artificial intelligence, automation, blockchain and smart packaging as tools for more efficient and traceable production, while noting that sensory quality, regulation, scale-up and consumer perception could limit adoption.
This systematic review examined randomized trials of berberine in women with polyendocrine metabolic ovarian syndrome, previously called polycystic ovary syndrome. Four trials involving 452 participants were identified, but all were judged to have a high risk of compromised integrity and were excluded from quantitative analysis. The researchers concluded that current evidence is insufficient to establish whether berberine is effective in this condition.
Researchers used a chiral form of phosphoserine in the lead iodide precursor for perovskite solar cells. The best device reached 26.04% efficiency and retained 90.2% of its initial efficiency after 1,000 hours of maximum-power operation.
Regulatory oversight, external audit quality and environmental governance were not significantly associated with the market value of listed Nigerian banks. The findings suggest these measures may support transparency and accountability more than they produce immediate gains in market valuation.
A qualitative study of 24 university students found that neurodivergent participants used generative AI to manage academic demands, energy and cognitive processing. They described it as essential scaffolding but also raised concerns about authenticity, over-reliance and interfaces that may exclude some users.
A special issue in International Politics reassesses three decades of relations between the European Union and Mediterranean countries through the idea of policy learning. It introduces a framework that considers both cooperation among actors and the extent to which they share power in decision-making.
A modelling study suggests that an earthquake on New Zealand’s Titri fault could increase flood exposure in the Taieri Basin by changing the ground and disrupting drainage. In one simulated rupture, Dunedin Airport was inundated to depths of 0.3–1.5 metres during an intense flood event.
