Superradiance is usually driven by light-mediated couplings, leaving the role of direct emitter interactions unclear. Now, it is shown that dipole–dipole interactions in diamond spins drive self-induced pulsed and continuous superradiant masing.

Researchers working on China’s fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have experimentally accessed a theorized “density-free regime” for fusion plasmas, achieving stable operation at densities well beyond conventional limits.

The results, reported in Science Advances, provide new insights into overcoming one of the most persistent physical obstacles on the path toward nuclear fusion ignition.

The study was co-led by Prof. Zhu Ping from Huazhong University of Science and Technology and Associate Prof. Yan Ning from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences. By realizing a novel high-density operating scheme on EAST, the team demonstrated that plasma density, long constrained by empirical limits in tokamak operation, can be substantially extended without triggering disruptive instabilities.

Kimura and Wong et al. have demonstrated how Tregs influence bile duct response to liver injury. Combinational immunotherapy that increases Treg number and stability is required for a more efficient bile duct repair program.

A new study of 4,812 Americans finds that emerging adults report the highest levels of both social connection and loneliness, suggesting that life instability, rather than isolation, drives social ill-being in youth.
