A study published in Engineering introduces a synchronous-asynchronous ambient noise observation system. It was tested in an abandoned parking lot in Hangzhou to detect karst features. This new system addresses challenges like non-uniform noise source distribution and enables cost-effective, high-resolution subsurface imaging for urban geohazard investigations.

Findings of new research suggest regular coffee consumption may contribute to improved health in older adults. Researchers found habitual coffee consumption was associated with a reduced risk of frailty - defined by presence of weight loss, weakness, exhaustion, slow walking speed, or low physical activity. The research is the first to analyse the relationship between coffee consumption and the underlying components of frailty.
