  "account": "Engineers in Australia and France have developed a novel way to create lightweight, strong, and buoyant structures that can float in water, overcoming the limitations of traditional open-cell metallic materials. By combining titanium alloy with expandable polyurethane foam, researchers have designed hybrid lattice metamaterials that maintain their structural integrity while incorporating water-excluding skeletal density. This new approach allows for the seamless integration of various materials, leading to potential applications in marine vehicles, floating platforms, and therapeutic devices.",
