A Chinese research team has developed a single-step femtosecond laser 4D printing technology that enables rapid and precise micro-scale deformation of smart hydrogels. This innovation, inspired by the hierarchical structure of butterfly wings, holds significant promise for applications in flexible electronics and minimally invasive medicine.

A KAIST research team led by Professor Keon Jae Lee has proposed an innovative theoretical framework and research strategies for AI-based wearable blood pressure sensors, paving the way for continuous and non-invasive cardiovascular monitoring. 

More than 31 million Americans (12%) report needing to borrow about $74 billion last year to pay for healthcare despite most having some form of health insurance, according to a new survey from West Health and Gallup.
