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.

Structure, Perfect Divisibility and Coloring of ($P_2\cup P_4, C_3$)-Free Graphs
Randerath {\em et al.} [Discrete Math. 251 (2002) 137-153] proved that every $(P_6,C_3)$-free graph $G$ satisfies $χ(G)\leq4$. Pyatkin [Discrete Math. 313 (2013) 715-720] proved that every $(2P_3,C_3)$-free graph $G$ satisfies $χ(G)\leq4$. In this paper, we prove that for a connected $(P_2\cup P_4, C_3)$-free graph $G$, either $G$ has two nonadjacent vertices $u,v$ such that $N(u)\subseteq N(v)$, or $G$ is 3-colorable, or $G$ contains Grőtzsch graph as an induced subgraph and is an induced s…

How modified RNA tricks the innate immune system
The innate immune system is the body's first line of defense against pathogens and foreign substances. An essential component of this system are pattern recognition receptors, which recognize non-self RNA—such as that from viruses and bacteria—and trigger an immune response.

PTSM: Physiology-aware and Task-invariant Spatio-temporal Modeling for Cross-Subject EEG Decoding
Cross-subject electroencephalography (EEG) decoding remains a fundamental challenge in brain-computer interface (BCI) research due to substantial inter-subject variability and the scarcity of subject-invariant representations. This paper proposed PTSM (Physiology-aware and Task-invariant Spatio-temporal Modeling), a novel framework for interpretable and robust EEG decoding across unseen subjects. PTSM employs a dual-branch masking mechanism that independently learns personalized and shared spat…

LamiGauss: Pitching Radiative Gaussian for Sparse-View X-ray Laminography Reconstruction
X-ray Computed Laminography (CL) is essential for non-destructive inspection of plate-like structures in applications such as microchips and composite battery materials, where traditional computed tomography (CT) struggles due to geometric constraints. However, reconstructing high-quality volumes from laminographic projections remains challenging, particularly under highly sparse-view acquisition conditions. In this paper, we propose a reconstruction algorithm, namely LamiGauss, that combines G…

Mantis: A Simulation-Grounded Foundation Model for Disease Forecasting
Infectious disease forecasting in novel outbreaks or low resource settings has been limited by the need for disease-specific data, bespoke training, and expert tuning. We introduce Mantis, a foundation model trained entirely on mechanistic simulations, which enables out-of-the-box forecasting across diseases, regions, and outcomes, even in settings with limited historical data. Mantis is built on over 400 million simulated days of outbreak dynamics spanning diverse pathogens, transmission modes…
