In the upper Abbay basin, cradle of the Blue Nile, a team of researchers have predicted soils of the future: what will happen to soil organic carbon if we bet on regenerative agriculture—returning residues, organic manure, cover crops, agroforestry? Their 50-year modelling unveils a mixed picture: yes, land can regain fertility and resilience if we feed soils more; but under warming and increasingly erratic rains, these benefits weaken and vary greatly across territories.

Africa’s agrifood system emits nearly 2.9 billion tonnes of CO₂ equivalent every year—more than a quarter of global sector emissions. An international study compares Africa’s trajectory with China’s and proposes concrete solutions—from water management in rice paddies to modernizing logistics chains—to produce more food without worsening the climate.

Researchers at the University of São Paulo identify a new factor that explains the high prevalence of Alzheimer’s disease in older people with Down syndrome. The discovery paves the way for disease prevention strategies in this population.

Simple quantum-classical neural networks achieve good results in classifying lesions with fewer computational parameters. Scientists from São Paulo State University demonstrated a hybrid model at an international symposium.

In Vietnam, like many countries around the world, modern food retail is expanding, food is becoming more processed and packaged, and unhealthy food marketing is pervasive across physical and digital spaces. These shifts deliver convenience and (in some cases) safer handling, but they also make less healthy options easier to find and harder to avoid. A new study by the Alliance of Bioversity International and CIAT, along with their colleagues, maps these changes and the policy responses and proposes a more robust framework for a faster response.

A vulture recently arrived at the Santos Municipal Orchid Garden and an owl living in captivity for ten years were colonized by antibiotic-resistant Escherichia coli.
