Ongoing research into the effect of environmental change on the buzzing of bees reveals that high temperatures and exposure to heavy metals reduces the frequency (and audible pitch) of non-flight wing vibrations, which could have consequences on the effectiveness of bee communication and their role as pollinators.

Are opinions on controversial political issues as divided as many people perceive them to be? Researchers from the Complexity Science Hub (CSH), the Leibniz Centre for Tropical Marine Research (ZMT) in Bremen and the University of California Merced have addressed this question in a study recently published in PNAS Nexus.

Melting glaciers may be silently setting the stage for more explosive and frequent volcanic eruptions in the future, according to research on six volcanoes in the Chilean Andes.

New research identifies the key causes of changes affecting river deltas around the world and warns of an urgent need to tackle them through climate adaptation and policy.

Deltas are low-lying areas that form as rivers and empty their water and sediment into another body of water, such as an ocean, lake, or another river.

Some of the largest in the world, such as the Rhine, Mekong, Ganges-Brahmaputra-Meghna, and Nile, are threatened by climate change, facing rising sea levels and increasing frequency of extreme events.

With approximately 500 million people today living within or adjacent to delta systems, this is a major issue.​

Forest fires cause irreversible ecological and economic losses worldwide, often exacerbated by delayed or inefficient rescue efforts. A new study presents a groundbreaking data-driven framework to revolutionize aviation emergency networks. By integrating fire probability predictions with multi-objective optimization, the research enables faster, cost-effective rescue planning tailored to real-world fire risks. Tested in China’s Hainan Province, the model reduces response times while balancing ecological and operational costs—offering a scalable solution for global forest protection.

A new study challenges the long-debated theory that a massive, kilometre-thick ice shelf once covered the entire Arctic Ocean. By analysing ocean sediments and running advanced climate models, researchers found that seasonal sea ice—rather than a continuous ice shelf—has been the dominant feature of the Arctic for the past 750,000 years. This discovery gives insights crucial for our understanding of how the Arctic has responded to climate change in the past—and how it might behave in the future.
