Maximum Lifetime of the Vegetative Biosphere

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract We use a three‐dimensional model to calculate steady‐state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO2 ${\text{CO}}_{2}$ mixing ratio. Comparison with prior results shows an overestimation of warming by one‐dimensional models when solar constant is increased and CO2 ...

A multi‐source fusion and dynamic verification framework for scientific knowledge graph construction: Methods, evaluation, and applications

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract The exponential growth of scientific literature—over 2.5 million papers and 3.5 million patents annually—poses critical challenges for knowledge discovery. To address these, we propose SCIMKG (Scientific Knowledge Graph), a framework for constructing scientific knowledge graphs via multi‐source heterogeneous multi‐source.

INB3P: A Multi‐Modal and Interpretable Co‐Attention Framework Integrating Property‐Aware Explanations and Memory‐Bank Contrastive Fusion for Blood–Brain Barrier Penetrating Peptide Discovery

Advanced Science, Volume 13, Issue 34, 19 June 2026.
INB3P is a multimodal framework for blood–brain barrier‐penetrating peptide prediction under extreme data scarcity and class imbalance. By combining physicochemical‐guided augmentation, sequence–structure co‐attention, and imbalance‐aware optimization, it improves predictive performance and interpretability.

bacNeo: A Computational Toolkit for Identifying Bacteria‐Derived Neoantigens in Human Cancers

iMetaMed, Volume 2, Issue 2, June 2026.
We present bacterial neoantigen (bacNeo), a multi‐omics‐based computational software to classify bacterial components (BACC), type bacteria‐bound HLA alleles (BACH), and prioritize bacterial peptides as neoantigens (BACP). Bacterial neoantigen potential is quantified by score for peptide antigenicity recognition & kinetics (SPARK), enabling ...
