A new study solves a long-standing climate mystery: Why don't the records of oxygen isotopes in cave formations like stalagmites—known as speleothems—from central southern China reflect the well-known 100,000-year cycles of ice ages seen in other global climate records? These speleothem records have long been considered a key indicator of the strength of the Asian summer monsoon, so their failure to show these major climate shifts has puzzled scientists for decades.

Researchers at Eötvös Loránd University are generating realistic drone footage of landscapes from even hundreds of years ago with the help of artificial intelligence. With their method, presented in the journal Land, the authors aim to introduce a new tool that helps to better understand the original functioning of a landscape and can support strategic decisions about current land use — for example, implementing water retention solutions in often drought-stricken areas such as the Hungarian Great Plain.

The remains of landscapes thought to have formed when ancient rivers flowed across East Antarctica have been discovered – and could help predictions of future loss from the ice sheet.

The Hong Kong University of Science and Technology (HKUST) is pleased to announce the launch of WavyOcean 2.0, an immersive digital twin platform of regional earth system. This upgraded platform deeply integrates digital technologies with innovative research in Earth system, creating the first "dynamic digital mirror" for the Guangdong-Hong Kong-Macau Greater Bay Area (GBA) and China's coastal regions. With these enhancement, WavyOcean 2.0 offers the latest data on ocean currents, marine ecology, atmospheric conditions, and the distribution of rivers and pollutants in terrestrial watersheds, along with comprehensive data analysis tools and immersive visualization interactive functions. 

The azuki bean beetle is a common pest of stored beans and peas. Researchers at Kyushu University have found that when beetles infected with Wolbachia bacteria are exposed to elevated temperature and carbon dioxide they tend to produce larger eggs to enhance the survivability of their offspring. Interestingly, these larger eggs gave rise only to male larvae.
