A team of Japanese scientists has developed a way to make and sell a type of ice cream that does not melt, capitalizing on a discovery made accidentally by a chef. Most ice cream starts melting just moments after it is scooped from a container and placed into a bowl or on a cone. Because of this, people have taken to eating it quickly. But now that may change, as a team in Japan has found a way to maintain the shape of ice cream no matter how slowly it is eaten.
