What if Mother Earth could sue for mistreatment?
University of VermontPeer-Reviewed Publication
The study highlights the transformative potential of the Rights of Nature, which views nature as a rights-bearing entity, not merely an object of regulation and subjugation by extractive industries. The Llurimagua case—a dispute over a mining concession in Ecuador’s cloud forest—illustrates this approach, providing a unique opportunity to rethink Earth system governance.
The paper was authored by a diverse team of researchers from the University of Vermont, Universidad de los Hemisferios, Centro Jambatu de Investigación y Conservación de Anfibios, Coordinadora Ecuatoriana de Organizaciones para la Defensa de la Naturaleza y el Medio Ambiente (CEDENMA), and the Garrison Institute.
Key Findings of the article:
Nature's Rights: Ecuador's recognition of Nature's Rights represents a monumental shift in Earth system governance, embedding humans within dynamic ecological processes and advancing Earth system law more pluralistically.
Community Action: The resistance to mining in Intag Valley exemplifies the power of community action and international solidarity in pursuing planetary health equity and justice.
Pluriversality: The concept of pluriversality challenges the Core’s hegemony of knowledge, emphasizing care, stewardship, and equitable coexistence with all life forms.
Legal Precedents: The Llurimagua case, involving two frog species and the Junín community, sets a robust legal model for harmonizing the ecosphere and ethnosphere, ensuring the health of both people and the planet.

Klippe emplacement mechanism: Structural analysis and geochronology redefines evolution of Longmen Shan thrust belt, Eastern Tibetan Plateau
Science China PressPeer-Reviewed Publication
The emplacement mechanism of klippes along Longmen Shan foreland thrust belt has been long in debate. A pioneering study published in Science China Earth Sciences has unveiled critical insights into those controversial structures. Conducted by researchers from the China University of Geosciences (Beijing), the study employs structural analysis and low-temperature thermochronology to reveal the formation mechanism and emplacement time of the Longmen Shan klippes, thereby proposing a new tectonic model for the evolution of the klippes.

Broomcorn millet cultivation in the SW East European Plain since the second millennium BC
Science China PressIn a paper published in SCIENCE CHINA Earth Sciences, a team of researchers employed systematic archaeobotanical flotation and AMS radiocarbon dating at two sites in Romania: Baia-În Muchie and Dobrovăț. It provides valuable data on the chronology of millet cultivation in the SW Eastern European Plain and enhances our understanding of early East-West exchanges and their impact on human-environment interactions in critical regions.

Curiosity rover identifies carbonates, providing evidence of a carbon cycle on ancient Mars
American Association for the Advancement of Science (AAAS)Peer-Reviewed Publication
NASA’s Curiosity rover has uncovered a hidden chemical archive of ancient Mars’ atmosphere, which suggests that large amounts of carbon dioxide have been locked into the planet’s crust, according to a new study. The findings provide in situ evidence that a carbon cycle once operated on ancient Mars and offer new insights into the planet’s past climate. The Martian landscape shows clear signs that liquid water once flowed across its surface, which would have required a much warmer climate than the planet has today. It is therefore thought that Mars’ CO2 atmosphere must have been thicker in the past, to maintain warmer conditions. A climate containing abundant liquid water and atmospheric CO2 is expected to have reacted with Martian rocks, triggering geochemical processes that produce carbonate minerals. However, while previous analyses of Martian rock have detected the presence of carbonates, the quantities found were lower than expected from geochemical models.
Using data from the Curiosity rover, Benjamin Tutolo and colleagues investigated carbonate minerals in part of Gale crater – which once contained an ancient lake. In 2022 and 2023, Curiosity drilled four rock samples from different stratigraphic units representing transitions from lakebed to wind-blown environments and analyzed their mineralogy using the rover’s onboard X-ray diffractometer. Tutolo et al. identified siderite (iron carbonate) in high concentrations – ranging from approximately 5% to over 10% by weight – within magnesium sulfate-rich layers. This was unexpected, because orbital measurements had not detected carbonates in these strata. Given its provenance and chemistry, the authors infer that the siderite formed by water-rock reactions and evaporation, indicating that CO₂ was chemically sequestered from the Martian atmosphere into the sedimentary rocks. If the mineral composition of these sulfate layers is representative of sulfate-rich regions globally, those deposits contain a large, previously unrecognized carbon reservoir. The carbonates have been partially destroyed by later processes, indicating that some of the carbon dioxide was later returned to the atmosphere, forming a carbon cycle. “As details of Mars’ geochemistry are discovered through orbital and rover investigations around the planet, additional clues are revealed about the diversity of potentially habitable environments,” write Janice Bishop and Melissa Lane in a related Perspective.
