Secure and steady 6G communication

Sixth-generation, or 6G, cellular networks are the next step in wireless communication, and electromagnetic terahertz waves are seen as crucial to its development. However, terahertz waves, with their higher frequency and shorter wavelength, are subject to greater interference from electromagnetic noise, making clear and secure transmission a challenge. Researchers have now created an electromagnetic wave absorber for waves between 0.1–1 terahertz (THz). This greatly expands the range of the terahertz frequency which could be commercially used in the future. The ultrathin film is inexpensive, environmentally friendly and can be used outdoors, as it is resistant to heat, water, light and organic solvents.

Scientists develop realistic ‘micro-gut’ model to study the relationship between gut microbes and human diseases

In a breakthrough for the advanced study of gut health, scientists have developed a 3D microscopic version of the human intestines condensed into a small chip about half the size of a five-cent coin. This new cell culturing platform, known as the Gut-Microbiome on a chip (GMoC), provides a realistic in vitro microgut model that allows researchers to examine the interactions of gut microbes and their collective impact on gut health. The chip offers a scalable, reproducible, and efficient method to dissect the roles of gut microbes and their community, which is of key interest for the preventive healthcare and pharmaceuticals industry.
