Green walls, effective acoustic insulation

Researchers have found that green walls are suitable for absorbing environmental noise and acting as acoustic insulation, improving life quality and reducing pollution. The study also shows that green walls can be effective in high and low frequencies, making them a potential solution for acoustic insulation.

Device speeds concentration step in food-pathogen detection

Researchers at Purdue University have developed a system that concentrates foodborne salmonella and other pathogens faster than traditional methods, enabling potential routine analysis within a single work shift. The device uses hollow thread-like fibers to filter out cells and recovers up to 70% of living pathogen cells.
