Global access to food crops is affected by transport costs and economic inequality‎

Producing enough food is only one part of ensuring global food security. A new study shows that transport networks and economic inequality are important factors in determining global food accessibility. A research team led by the University of Oulu, together with researchers from Aalto University and Pellervo Economic Research (PTT), Finland, developed a new spatial accessibility framework to examine how effectively global transport systems connect food supply with demand under different economic and disruption scenarios.

AI-driven literature mining speeds discovery of heat-stable lead-free dielectric materials‎

Artificial intelligence has analyzed data scattered across hundreds of research papers to discover new lead-free dielectric materials that maintain stable performance even at high temperatures. The study presents a new approach that could transform materials discovery from a trial-and-error process into a data-driven one.

Century-old physics idea explains why cubic fluid equations work‎

The Korea Institute of Civil Engineering and Building Technology (KICT) has developed a new cubic equation of state (EOS) that provides a physical justification for a mathematical structure that the chemical and petroleum industries have relied on for more than half a century without a first-principles explanation.

Tourist sign translations made more culturally fluent by AI system‎

A new artificial intelligence, or AI, translation model could improve the accuracy and cultural appropriateness of Chinese-English public signs at tourist attractions, according to research in the International Journal of Environmental Technology and Management. The approach treats translation as more than a word-for-word conversion and combines machine translation with principles from eco-translatology, in which language, culture and social context are considered.

Occupational health challenges require more than individual support, new doctoral study shows‎

Mental health issues are now the most prevalent cause of sick leave in Finland. It is common for an employee's declining occupational well-being to result in a sick leave referral, while nothing changes at the workplace itself.

Scarce emergence of new species drove the decline of African megaherbivores, study suggests‎

A study by the National Museum of Natural Sciences (MNCN-CSIC), the National Research Center on Human Evolution (CENIEH) and the University of Alcalá offers a new explanation for the decline of African megaherbivores. These animals, weighing more than a tonne (2,200 pounds) and today including elephants and hippopotamuses, are known for acting as ecosystem engineers. The results, published in Nature Communications, reveal that their loss of diversity throughout history was not due to their being more vulnerable to extinction, as had previously been proposed, but rather that their decline was driven by particularly low rates of speciation—the emergence of new species.

Thinner lenses, brighter colors: Metalens research clears two hurdles for AR and VR glasses‎

AR and VR glasses once seen only in science fiction may soon be realized not as bulky stacks of lenses but as a single eyeglass-like optical element. That future is now closer to reality.

Rising carbon dioxide is supercharging grass growth in African savannas, study finds‎

Rising atmospheric carbon dioxide is boosting grass growth in Africa's water-limited savannas, according to a new study led by the University of Sheffield.

Researchers build 'digital twin' to model Manhattan air quality‎

Cornell engineers have developed a "digital twin" framework that creates a real-time virtual representation of urban carbon dioxide conditions, providing a tool that could help city planners monitor emissions, identify hotspots and evaluate potential interventions before implementing them in the real world.

North Sea wind farm expansion may shift rain offshore, simulations suggest‎

Offshore wind farms are a key pillar of the energy transition. The European Union plans to expand offshore wind capacity in the North Sea by 2050. A new study by the Helmholtz-Zentrum Hereon indicates that a very extensive expansion could influence regional precipitation patterns: While precipitation over the sea could increase, it could decrease in coastal regions.
