Magnetic susceptibility measurements showed a diamagnetic shift of 85% of expected Meissner effect strength, suggesting partial superconductivity.  \n- **Significance:** This marks the first independent replication under ambient pressure, though full Meissner effect confirmation remains pending.  \n- **Source:** *Nature*, April 6, 2026, advance online publication: https://www.nature.com/articles/s41586-026-00451-8\n\n### 2. **Breakthrough in Twisted Graphene Bilayer Stability**\n- **Date:** April 8, 2026  \n- **Institution:** Massachusetts Institute of Technology (MIT), USA  \n- **Lead Researcher:** Pablo Jarillo-Herrero  \n- **Finding:** MIT researchers stabilized the superconducting state in twisted bilayer graphene (at the magic angle of 1.05°) up to 25 K, a 5 K improvement over prior results, by encapsulating the structure in hexagonal boron nitride and applying strain tuning.  \n- **Details:** Field-effect transistor measurements demonstrated coherent supercurrent flow over 10 micrometers, a 3x improvement in coherence length.  \n- **Significance:** Enhanced stability brings practical quantum devices closer to feasibility.  \n-","keywords":["dynamic:superconductor-research","zo-research","quantum-computing"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
