Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around more, according to a new study from researchers at UCL and UCLH.upon the spread of airborne particles, which are similar to those breathed out by a person with a viral respiratory infection such as SARS-CoV-2 or influenza.
The researchers found that while use of built-in ventilation and PACs can reduce particle spread in some scenarios, in some experiments the use of PACs increased aerosol spread by up to 29% between neighbouring rooms. Built-in ventilation potentially increased aerosol migration across the clinic by up to 5.5 times more than if no ventilation was used.
"Putting air cleaners in rooms led to unexpected increases in the circulation of aerosols in some cases, but it took months to understand what we were seeing. Each scenario produced different, unexpected results, depending on the spaces and airflow sources involved.

3D-Printed Wall Coverings Naturally Absorb Humidity, Reducing Need for Energy-Intensive VentilationResearchers at ETH Zurich have developed a novel 3D-printed wall and ceiling covering that effectively absorbs and stores excess moisture from the air. This innovative solution utilizes a hygroscopic material to mitigate high humidity levels in crowded indoor spaces, minimizing the reliance on traditional mechanical ventilation systems. The material, composed primarily of recycled marble quarry waste, is bound together using a geopolymer binder, creating a durable and environmentally friendly building component.

Night Owls May Face Increased Health Risks, Study FindsA new study published in Experimental Physiology reveals that individuals who identify as 'night owls' may be at a higher risk for certain diseases due to their sleep patterns. Researchers found that night owls had a reduced ability to use fat for energy, leading to potential fat accumulation and increased disease risk. They also exhibited higher rates of insulin resistance, a factor linked to heart disease and type 2 diabetes. Early birds, on the other hand, showed better metabolic health with increased fat utilization and improved fitness levels.
