Understanding the relationship between food waste, climate change, and population aging
Researchers investigated how household food waste is related to a variety of demographic and economic factors and found that age plays a complex role. Credit: Dr. Yosuke Shigetomi, Ritsumeikan University Producing food and delivering it to people’s tables requires the consumption of large amounts of energy and resources. Unfortunately, around one-third of the food produced around the world goes to…

X-rays advance understanding of Earth’s core-mantle boundary and super-Earth magma oceans
Schematic diagram of the experimental setup available at the MEC end station. Four epiX 10k detectors cover the Q range from 15 to 106 nm-1 with an X-ray beam energy of 17 keV. The complete signal can be reconstructed by stitching together the diffuse scattering recorded by each detector. Credit: Nature Communications (2024).

Geologists discover mysterious subduction zone beneath the Pacific Ocean, reshaping understanding of Earth’s interior
A map depicting the area where the ancient ocean floor was discovered. Credit: Jingchuan Wang, University of Maryland. Scientists at the University of Maryland have discovered evidence of an ancient ocean floor that sank deep into the Earth during the age of dinosaurs, casting doubt on existing theories about the Earth’s internal structure. This previously unstudied section of the ocean…

Understanding Antarctica’s impact on sea level rise
Antarctic bedrock landforms and drainage basins and their estimated potential for global mean sea level rise (in metres). Areas considered particularly vulnerable are highlighted in blue. Source: Australian Antarctic Data Centre, 2024. DOI: 10.26179/q3fx-8p19 Will melting of the Antarctic Ice Sheet (AIS), Earth’s largest ice mass, cause global sea levels to rise by 5 metres, 2 metres or even less…

Atmospheric Lidar instrument on climate satellite improves understanding of aerosols and clouds
Ground stations of the European research infrastructure ACTRIS play a key role in calibrating data from the EarthCARE satellites. In recent years, these ground stations have been installed and expanded to analyse aerosol particles and clouds using remote sensing instruments such as lidar and radar. Around 50 stations from Europe (photo: TROPOS, Leipzig) and abroad take part in the atmo4ACTRIS…
