In a new study published on Science Advances, Yichao Zhao and a research team in integrated bioelectronics and materials and engineering in the U.S. engineered a disposable, free-standing electrochemical sensing system (FESS). ...
Phys.org / Protein modification with ISG15 blocks coxsackievirus pathology via antiviral and metabolic reprogramming
During early encounters between a pathogen and a cell, receptors located on the cell surface, in the cytosol or within endosomal (storage) compartments engage with the pathogen's nucleic acid (DNA/RNA) or pathogen-associated ...
Phys.org / Realizing kagome spin ice in a frustrated intermetallic compound
Exotic phases of matter known as spin ices are defined by frustrated spins that obey local "ice rules"—similar to electric dipoles in water ice. Physicists can define ice rules in two-dimensions for in-plane Ising-like spins ...
Phys.org / Researchers demonstrate first terahertz quantum sensing
Quantum physicists rely on quantum sensing as a highly attractive method to access spectral regions and detect photons (tiny packets of light) that are generally technically challenging. They can gather sample information ...
