Nanotechnology deals with particles that are several thousand times smaller than the human hair, and it is being put to use in a variety of applications such as drug delivery and diagnostic tests.
Indian scientists have developed a remote sensing technique that uses satellite data to delineate between various coastal landforms like beaches, mangroves and marshes. This method can help monitor and understand impacts of natural disasters as well as human activities on coastal ecosystem.
