Researchers at WVU and Marshall University are analyzing COVID-19 samples to identify new variants, including the UK Variant B.1.1.7, which is believed to be more contagious than the original virus. The team aims to understand how these variants evolve and potentially develop therapeutics or vaccines.
The generation of dissipative solitons and coherent frequency combs in a photonic dimer made of two microresonators enables real-time tuning of the soliton-based frequency comb. Soliton hopping, a phenomenon not present at the single-particle level, can be used for generating configurable combs in the radio-frequency domain.
The CUHK research team found that viscoelasticity can be harnessed to control active matter's self-organisation, enabling the creation of self-driven devices. The discovery has implications for soft robotics, tissue engineering, and microbial physiology, as well as the dispersal of biofilms and gut microbiome.
