Here, we proposed a screw dislocation-mediated three-dimensional (3D) printing strategy for scalable, integrated manufacturing of metamaterial catalysts. Specifically, screw dislocation was introduced into the 3D printing process to mediate the simultaneous synthesis of 3D architecture and chiral surface nanostructures, effectively eliminating conventional heterointerfaces.

CRISPR-GPT for agentic automation of gene-editing experiments.

Performing effective gene-editing experiments requires a deep understanding of both the CRISPR technology and the biological system involved.

We present CRISPR-GPT, an LLM agent system to automate and enhance CRISPR-based gene-editing design and data analysis.

Landscape of mobile genetic elements and their functional cargo across the gastrointestinal tract microbiomes in ruminants.

Background: Mobile genetic elements (MGEs) drive horizontal gene transfer and microbial evolution, spreading adaptive genes across microbial communities. While extensively studied in other ecosystems, the role of MGEs in shaping ruminant gastrointestinal microbiomes-especially their impact on diversity, adaptation, and dietary responsiveness-remains largely unexplored. This study systematically profiles MGE distribution and functionality across gastrointestinal regions in multiple ruminant species to advance our understanding of microbial adaptation.

Atomic-scale self-rearrangement of hetero-metastable phases into high-density single-atom catalysts for the oxygen evolution reaction.

Maximizing metal-substrate interactions by self-reconstruction of coadjutant metastable phases can be a delicate strategy to obtain robust and efficient high-density single-atom catalysts. Here, we prepare high-density iridium atoms embedded ultrathin CoCeOOH nanosheets (CoCe-O-Ir) by the electrochemistry-initiated synchronous evolution between metastable iridium intermediates and symmetry-breaking CoCe(OH) substrates. The CoCe-O-Ir delivers an overpotential of 187 mV at 100 mA cm and a steady lifespan of 1000 h at 500 mA cm for oxygen evolution reaction.

CHC22 clathrin recruitment to the early secretory pathway requires two-site interaction with SNX5 and p115.

The two clathrin isoforms, CHC17 and CHC22, mediate separate intracellular transport routes. CHC17 performs endocytosis and housekeeping membrane traffic in all cells. CHC22, expressed most highly in skeletal muscle, shuttles the glucose transporter GLUT4 from the ERGIC (endoplasmic-reticulum-to-Golgi intermediate compartment) directly to an intracellular GLUT4 storage compartment (GSC), from where GLUT4 can be mobilized to the plasma membrane by insulin.

This support, prepared via the liquid metal dealloying method, offers a high specific surface area and rapid mass/charge transfer channels.

Experimental investigation on coupled-bunch instability and suppression for the upgrade of Beijing Electron-Positron Collider (BEPCII).

After touching the design collision luminosity of 1.0 × 1033 cm-2 s-1 in 2016, this target has not been reached again for the upgrade of Beijing Electron-Positron Collider during physical collision operation in subsequent years due to various factors, such as the collision background, noise, and equipment stability under high power operation. One of the most serious factors was the beam instability, especially the coupled-bunch instability, whose sideband distribution was clearly displayed on the spectrum analyzer when the feedback system was OFF.
