3D scans show that smaller dinosaurs did not shy away from feeding their deceased relatives. This is the conclusion of a new study from Aarhus University, recently published in the scientific journal Evolving Earth. 

This study introduces a custom-designed NV quantum sensing based microscopy for high-sensitivity microscopic magnetic imaging (MMI) of individual Chang'e-5 lunar regolith grains, achieving the first direct observation of surface magnetic field distributions at the single-particle scale. Overcoming the limitations of traditional orbital magnetometry (kilometer-scale) and macroscopic bulk rock-magnetic measurements (e.g., VSM), our approach realizes the separation and identification of magnetic signals at the micro- to nanoscale. Results indicate that native irons in basalt clasts exhibits weak and directionally uniform magnetism, suggesting it records the lunar paleomagnetic field during magma cooling; in contrast, carriers such as nanophase iron and Fe-Ni alloys in breccia grains, as well as crack-associated magnetic “stripe” features, display distinct magnetic signals reflecting the influence of multiple geological processes, including meteorite impacts and space weathering. Overall, this study advances lunar magnetic detection to the single-particle microscopic level, providing direct evidence for understanding the origin of lunar magnetic anomalies and the magnetic field evolution history, offering a new microscopic perspective for lunar and planetary science.

Scientists have solved a 66 million year old mystery about why the earth cooled after the age of the dinosaurs.

A new study led by former Syracuse University doctoral student Ruliang He and co-authored by his advisor, Earth and environmental sciences Professor Zunli Lu, reveals that Earth's ancient tropical oceans were fundamentally different from today's. The research, recently published in Nature Geoscience, shows marine oxygen levels were higher near the equator than at the middle latitudes during the Proterozoic Eon, which began 2.5 billion years ago and ended 539 million years ago. 

Atmospheric scientist Amanda Staudt will join the American Meteorological Society (AMS), the professional society for weather, water, and climate sciences and services, as its new executive director in March 2026.
