Researchers at ETH Zurich have developed a novel phononic metamaterial that can precisely control mechanical waves, enabling the harvesting of energy from vibrations and processing signals mechanically. The material features a specific pattern with varying unit cell sizes, allowing it to redirect waves along predefined paths.
A study published in Nutrients found associations between high homocysteine levels and fatigue-related outcomes, including physical fatigue in men and decreased motivation in women. Maintaining a well-balanced diet rich in vitamin B12 and folate is essential to prevent homocysteine level increases.
A novel study shows that adults with atopic dermatitis, particularly those with childhood onset, report significantly greater limitations in their educational and professional choices. The findings highlight the need for comprehensive, early, and multidimensional care to address the long-term impact of AD on life trajectories.
Researchers identified a specific gut microbial group that can dramatically worsen sepsis by excessively sensitizing immune cells. A Muribaculaceae-enriched microbiota was found to exacerbate TLR4-dependent Acinetobacter baumannii-induced hyperinflammatory sepsis.
