High-voltage direct current (HVDC) lines are often described as the power highways of the clean-energy era, carrying large amounts of electricity across long distances with high efficiency. 

The existing magnetic-responsive SERS substrates have difficulty in regulating the spatial coupling between the carrier of the analyte and the plasmonic hotspots, which limits the enhancement effect. This study uses NdFeB/PS/Ag as the plasmonic substrate and the core-shell magnetic nanoparticles (Fe₃O₄@SiO₂@Ag) (FSA) as the molecular capture carrier. By adjusting the magnetization state and magnetic field gradient of the NdFeB sheet, the spatial distribution of FSA particles can be controllably regulated.

Neurodegenerative diseases, cerebrovascular disorders and other age-related neurological conditions are major causes of long-term disability. A review published in SCIENCE CHINA Life Sciences by researchers from Huashan Hospital, Fudan University, examines how damaged nuclear DNA and mitochondrial DNA can become immune danger signals. The authors highlight cGAS-STING as a key molecular hub linking cellular damage, inflammaging and neuroimmune dysfunction, and discuss opportunities for more precise therapeutic intervention.

Transition-metal sulfides can accelerate sulfur reactions in all-solid-state lithium-sulfur batteries, but their own stability during cycling has received less attention. Researchers uncovered two major catalyst failure pathways and used these insights to develop a compositionally disordered catalyst. The new design suppresses phase separation and transition metal migration while maintaining carrier transport, enabling efficient sulfur conversion under demanding battery conditions.

Researchers have uncovered how compressive strain and oxygen contents drive Ruddlesden–Popper nickelate thin films toward superconductivity. X-ray reveals that key electronic orbitals become increasingly delocalized while long-range magnetic order is suppressed, yet short-range magnetic excitations remain robust. The findings identify an orbital-selective pathway toward high-temperature superconductivity in Ruddlesden–Popper nickelates.

Researchers have uncovered an unexpected antiviral role for PGK1, an enzyme best known for its function in glucose metabolism. Acting through its non-canonical protein kinase activity, PGK1 phosphorylates the host protein heat shock protein 90-alpha (HSP90AA1), reduces its chaperone function, and promotes its proteasomal degradation. The resulting loss of viral protein stability restricts the replication of several RNA and DNA viruses, highlighting a potential host-directed antiviral strategy.
