Human influence reduces natural land carbon stocks by 24%, study finds
Human activities, such as deforestation and the expansion of agricultural areas, have a massive impact on the natural state of ecosystems. As a result, large amounts of carbon are released into the atmosphere, contributing substantially to anthropogenic climate change.

Plastics threaten ecosystems and human health, but evidence‑based solutions are under political fire
Negotiations toward a global, legally binding plastics treaty are set to resume this summer, with the United Nations Environment Program announcing that the Intergovernmental Negotiating Committee on plastic pollution will reconvene in August.

Autonomous Oil Spill Response Through Liquid Neural Trajectory Modeling and Coordinated Marine Robotics
Marine oil spills pose grave environmental and economic risks, threatening marine ecosystems, coastlines, and dependent industries. Predicting and managing oil spill trajectories is highly complex, due to the interplay of physical, chemical, and environmental factors such as wind, currents, and temperature, which makes timely and effective response challenging. Accurate real-time trajectory forecasting and coordinated mitigation are vital for minimizing the impact of these disasters. This study…

New study: 60% of the world’s land area is in a precarious state, putting at risk the ability of the plant world to acquire enough energy through photosynthesis to maintain the material flows of carbon, water and nitrogen that support the ecosystems.

60 percent of the world’s land area is in a precarious state
15.08.2025 – A new study maps the planetary boundary of “functional biosphere integrity” in spatial detail and over centuries. It finds that 60 percent of global land areas are now already outside the locally defined safe zone, and 38 percent are even in the high-risk zone. The study was led by the Potsdam Institute for Climate Impact Research (PIK) together with BOKU University in Vienna and published in the renowned journal One Earth.

The global human impact on biodiversity - Nature
Key measures of biodiversity were quantified and found to be affected by human pressures that shifted community composition and decreased local diversity across terrestrial, freshwater and marine ecosystems.

Soft X-ray line emission from hot gas in intervening galaxy halos and diffuse gas in the cosmic web
Cosmic hot gas emission is closely related to halo gas acquisition and galactic feedback processes. Their X-ray observations reveal important physical properties and movements of the baryonic cycle of galactic ecosystems. However, the measured emissions toward a target at a cosmological distance would always include contributions from hot gases along the entire line of sight to the target. Observationally, such contaminations are routinely subtracted via different strategies. In this work, we a…

BetaWeb: Towards a Blockchain-enabled Trustworthy Agentic Web
The rapid development of large language models (LLMs) has significantly propelled the development of artificial intelligence (AI) agents, which are increasingly evolving into diverse autonomous entities, advancing the LLM-based multi-agent systems (LaMAS). However, current agentic ecosystems remain fragmented and closed. Establishing an interconnected and scalable paradigm for Agentic AI has become a critical prerequisite. Although Agentic Web proposes an open architecture to break the ecosyste…

There's this fascination with what science is discovering about unexpected ecosystems, coupled with dismay at the changes we are causing without intent, thought, or (unfortunately) care. Until it's too late to stop what we are doing, to our own detriment
