Well, most of those (at the moment) are just novel elements anyways. At the moment, they have half lives of shorter than a second, so you can't do much with them. However, due to the fact that their half lives seem to be getting a bit longer than what you flat out expect from increased mass alone, it hints at the concept of an "island of stability" or something, and those might have potential uses. Even if that stability is low, and there are no physical uses, the properties might allow us to further understand other elements better with a larger sample size of properties.
