Scientists in Brazil and Peru are using machine learning for early outbreak predictions and Wolbachia-infected mosquitoes to curb dengue fever, amid rising cases fueled by climate change. In Lima, a 2024 epidemic overwhelmed hospitals, prompting adaptations now informing regional strategies. These efforts offer models as subtropical U.S. areas report local transmissions.

Scientists at Harper Adams University in the United Kingdom used fiber optic cables and distributed acoustic sensing to demonstrate how plowing destroys soil structures that hold water. The research, detailed in a new paper, shows tilled fields retain less moisture than undisturbed ones despite appearing looser. Findings highlight benefits of regenerative farming practices like no-till agriculture.

A study on the scarlet monkeyflower (Mimulus cardinalis) shows it recovered from a severe drought in California via rapid evolution, marking the first observed case of evolutionary rescue in the wild. Researchers led by Daniel Anstett at Cornell University tracked the plant's response to the 2012-2015 megadrought. While this offers hope for species facing climate change, experts note limitations for long-term adaptation.

Researchers at Trinity College Dublin have identified a universal thermal performance curve that governs how organisms across the tree of life respond to temperature changes. This pattern shows performance improving gradually up to an optimal point before declining sharply. The finding, based on analysis of over 2,500 curves from diverse species, suggests evolutionary constraints on adapting to warming climates.

Quality seeds resilient to climate change are the main pillar in preventing hunger and ensuring food security across Africa. According to Dr. Yacouba Diallo, Secretary General of the African Seed Trade Association (AFSTA), agricultural reforms cannot succeed without robust seed systems. AFSTA will host its 2026 congress in South Africa to discuss these issues.

Global news coverage of climate change has fallen 38 percent since its 2021 peak, according to data from the University of Colorado Boulder's Media and Climate Change Observatory. This decline, accelerating amid political chaos and other crises, has real-world effects on public awareness and policy action. Experts attribute the shift to competing news priorities and pressures under the Trump administration.
