Shanghai, July 18--At the "AI for the Real World" forum during the 2026 World Artificial Intelligence Conference (WAIC), YUAN Yang, Associate Professor at Tsinghua University's Institute for Interdisciplinary Information Sciences, delivered a keynote speech--Calculus of Intelligence: A Theoretical Framework for Agents and unveiled iFuture, a new academic journal focusing on artificial intelligence(AI), alongside its supporting platform, Oscholar, demonstrating a fresh approach to academic publishing and research paradigms in the age of AI.

Dual-atom catalysts (DACs) show great promise in catalyzing oxygen reduction/evolution reactions (ORR/OER), yet facing significant challenges in achieving simultaneous high catalytic activity and stability in zinc–air batteries (ZABs). In this study, we synthesized a porous three-dimensional carbon aerogel anchored with atomically isolated FeN₄/NiN₄ dual sites and Ru₆ nanoclusters (FeN₄–Ru₆–NiN₄@PCA) to address these challenges. The adjacent Ru₆ nanoclusters effectively regulate the geometric structures of FeN₄ and NiN₄ sites and catalyze the formation of a highly graphitic carbon matrix. These structural features endow FeN₄–Ru₆–NiN₄@PCA with remarkable ORR/OER activity and stability, outperforming counterparts with only FeN₄/NiN₄ dual species and benchmark Pt/C and RuO₂ catalysts. Density functional theory calculations reveal that Ru6 clusters induce obvious electron redistribution of FeN₄/NiN₄ sites and optimize their electron transfer to the key oxygen intermediates (OH*) at the rate-determining steps, thereby accelerating the ORR and OER kinetics. When employed FeN₄–Ru₆–NiN₄@PCA as the cathode catalyst in ZABs, the resulting ZAB delivers a peak power density of 197.76 mW cm^–2 and demonstrates outstanding cycling stability over 2000 h, highlighting its great potential for use in applications of energy storage device.

The study analyzed data from 514 smallholder farmers involved in Climate-Smart Villages in Guatemala and Honduras. 

The findings show that trust among farmers is a key factor in increasing the likelihood of knowledge sharing about climate-smart agricultural practices. 

The research found that mutual support is particularly important in communities with low levels of trust, helping to sustain the flow of knowledge among farmers. 

Published in Science, an international study with the contribution of Politecnico di Milano: carbon dioxide can be used as an oxygen source in a key reaction for the production of molecules useful to the chemical, pharmaceutical and materials industries

Blanco de Piura, a native fine-flavor cacao variety recognized for its white beans and high sensory quality, achieved yields of 1,500 kg of dry beans per hectare, comparable to those of high-yielding commercial varieties. 

Renewing trees through grafting with selected native plant material increased production by 59% in just three years. 

The findings show that it is possible to increase productivity and farmers' incomes while conserving the genetic diversity of native cacao. 

An international study led by researchers from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) reveals that Indigenous, African and Afro-descendant communities relied more heavily on marine resources, while communities of immigrants from Germany consumed mainly plant species and terrestrial products.
