Scientists study and synthesize new transuranium elements in the laboratory because these elements that are not yet to be made or discovered may help the development of every human life.
For example, The first transuranium element made was plutonium. It’s fissionable and tons have since been produced. Another element made on an industrial scale is americium, used for detecting gasses in smoke detectors. Others were initially designated for medical treatments (targeted cancer therapies) but have largely been displaced by other cheaper alternatives. These elements serve their purposes very well and make life easier. To think of it if americium is not discovered fire detectors won't be made.
