Parallel LLM agents tackle complex tasks by exploring multiple trajectories, yet useful discoveries remain isolated in individual execution histories. Existing sharing methods often select or summarize information before other agents' needs become clear, potentially overlooking details that become important later. We propose Ask on Demand (AOD), a communication framework that enables agents to seek targeted peer assistance when specific information needs arise.
Knowledge evolution and emerging emphasis on outcome standardization in diabetes remission research: a multidatabase bibliometric analysis, 1950 to January 2026
Abstract Background: Diabetes remission has evolved from an infrequently reported clinical observation into an increasingly defined and assessable outcome. Previous bibliometric studies have largely relied on the Web of Science and focused on literature published after 2000, limiting characterization of earlier knowledge foundations and long-term thematic change.
Engineering bamboo as a multiscale platform for carbon-negative materials
Abstract Carbon-negative materials are increasingly central to credible net-zero strategies; however, their climate benefits depend on transparent life-cycle boundaries, realistic end-of-life scenarios and carbon storage. Bamboo is a fast-growing lignocellulosic resource that combines high biomass productivity with the ability to sequester atmospheric carbon in long-lived materials.

Lactobacillus paracasei L9 Ameliorates Pulmonary Fibrosis in Aged Mice via Gut-Lung Axis-Mediated Regulation of Immune Cell Migration
1 Introduction In recent years, numerous studies have shown the lung may develop fibrosis with age (Moss et al. 2022). And because of the aggravation of global aging, the medical burden of pulmonary fibrosis (PF) increases rapidly (Hutchinson et al. 2015). Most patients with PF have a slow progressive decline in lung function that eventually leads to respiratory failure, while 10%–15% of patients experience an unusually rapid decline over several months (Ley et al. 2011).
Hedyotis diffusa and Scutellaria barbata enhance the anti-ovarian cancer effect of cisplatin through network pharmacology analysis and molecular docking technology
Abstract Hedyotis diffusa Willd (HD) and Scutellaria barbata D.Don (SB) are widely used traditional Chinese herbs with detoxifying properties and anti-tumor activities. The HD-SB pairing demonstrated significant anti-tumor efficacy in cancer, however, the synergistic potential of HD-SB with cisplatin in the treatment of cancer remains poorly understood. The current work aimed to uncover the synergistic effect of HD-SB with cisplatin on ovarian cancer.

Ab initio characterization of protein molecular dynamics with AI2BMD - Nature
Abstract Biomolecular dynamics simulation is a fundamental technology for life sciences research, and its usefulness depends on its accuracy and efficiency1,2,3. Classical molecular dynamics simulation is fast but lacks chemical accuracy4,5. Quantum chemistry methods such as density functional theory can reach chemical accuracy but cannot scale to support large biomolecules6.
From static prediction to dynamic characterization: AI2BMD advances protein dynamics with ab initio accuracy
The essence of the biological world lies in the ever-changing nature of its molecules and their interactions. Understanding the dynamics and interactions of biomolecules is crucial for deciphering the mechanisms behind biological processes and for developing biomaterials and drugs. As Richard Feynman famously said, “Everything that living things do can be understood in terms of the jigglings and wigglings of atoms.” Yet capturing these real-life movements is nearly impossible through experiments.

Whole Rock, Mineral Chemistry during Skarn Mineralization-Case Study from Tongshan Cu-Mo Skarn Profile
1. Introduction Skarn is a type of metamorphic rock primarily formed by contact metasomatism [1]. Swedish geologists initially coined the term “skarn” to refer to a green, calcic siliceous rock mainly composed of minerals such as garnet, pyroxene, hornblende, feldspar and epidote. The process of skarn mineralization is frequently linked with the concentration of metallic elements, leading to the formation of skarn-type deposits [1,2].
Study on the Overmolding Process of Carbon-Fiber-Reinforced Poly (Aryl Ether Ketone) (PAEK)/Poly (Ether Ether Ketone) (PEEK) Thermoplastic Composites
3.1. Influence of Mold Temperature on the Interfacial Bonding Strength The viscosity–temperature curves of PAEK and PEEK resin at the shear rate of 1000 s−1 are shown in Figure 3. The viscosity of PAEK at 340 °C~400 °C is about 89~237 Pa·s, and for PEEK at 360 °C~420 °C is 203~330 Pa·s. Both resins have shear-thinning behavior, and the viscosity changes tend to be consistent with the increase in temperature (the viscosity decreases with the increase in temperature).
