Climate extremes are adversely affecting cacao production. A recent study by Hasanuddin University highlights the potential of multistrata shade structures in addressing these challenges. Researchers show how a mix of shade trees—such as coconut, banana, and Gliricidia sepium—can help cacao plants grow better and become more resilient. These trees can improve soil fertility and help cacao plants cope with environmental variability—offering a pathway toward more resilient and sustainable smallholder agriculture.

A new decades-long study of oceanographic data provides the first evidence that deep-ocean heat has moved closer to Antarctica, threatening the fragile ice shelves that fringe the continent.

A new review synthesizes research on Tibetan Plateau lakes, revealing that climate warming is turning these high-altitude ecosystems into major greenhouse gas sources. Melting permafrost and retreating glaciers feed thermokarst lakes, which are hotspots for methane emissions. The study calls for new models that include microbial mechanisms to predict and manage these emissions.

A study of over 3,100 middle-aged and older adults in China found that long-term exposure to particulate matter (PM2.5 and PM2.5-10) significantly increases the risk of heart disease. The risk is highest for those with advanced cardiovascular-kidney-metabolic (CKM) syndrome. Accelerated biological aging explained about 9% of this effect, highlighting the need for targeted protections.

The Middle East and North Africa (MENA) region faces considerable challenges from ticks and tick-borne diseases (TBDs), exacerbated by climate change and its impact on human and animal health, as well as overall productivity. To address these interconnected issues, the United Arab Emirates University, located in Al Ain, Abu Dhabi Emirate, United Arab Emirates (UAE), hosted a multinational, transdisciplinary One Health symposium on climate change, ticks, and tick-borne diseases. The event brought together experts from across the region and beyond, featuring seven invited speakers who explored a wide range of topics, including climate change, TBDs of humans and animals, tick research in the UAE, and the One Health approach. The symposium highlighted major knowledge and research gaps, particularly in underexplored areas such as acaricide resistance, tick vaccine development, tick–pathogen interactions, wildlife–livestock interfaces, and the circulation and movement of tick-borne pathogens across the region. Discussions underscored the heavy burden of ticks and TBDs in the MENA region and their complex economic and public health implications. Participants emphasized the need for regional collaboration, enhanced tick surveillance, pathogen detection, and integrated management strategies. The symposium also encouraged the establishment of future alliances and partnerships among universities, government departments, and research institutions to foster joint research projects, resource sharing, and knowledge exchange. Within the One Health paradigm, participants concluded that regional priorities should focus on identifying and understanding tick-related problems, strengthening cross-sectoral cooperation, utilizing regional expertise and infrastructure, and engaging all stakeholders including the public in sustainable tick and TBD management. This collaborative approach is essential to mitigate the multifaceted challenges posed by ticks, tick-borne pathogens, and a changing climate in the MENA region.

Beavers are spreading northwards into the Arctic and a new study provides detailed evidence of their expansion by dating the changes they have been making to the tundra landscape. The research, which combines tree ring analysis (looking at beaver browsing scars) with satellite imagery of surface water (highlighting dams), has allowed scientists to track and date beaver movements in remote areas of the Canadian Arctic.
