Researchers have created organic materials for brain and heart pacemakers, which rely on uninterrupted signal delivery to be effective. Using a plastic base known as polypropylene, the researchers added a specially formulated clay called Montmorillonite and different ratios of graphene, one of the strongest lightweight materials. They created five different materials that could be performance-tested and took detailed measurements of the structure of the composite materials using scanning electron microscopy.

Different types of cancer have unique molecular 'fingerprints' which are detectable in early stages of the disease and can be picked up with near-perfect accuracy by small, portable scanners in just a few hours, according to a new study. The discovery sets the foundation for creating new, non-invasive diagnostic tests that detect different types of cancer faster and earlier than currently possible.
