“It’s a really elegant and creative design to make tough adhesives that work in wet environments,” says Mark W. Grinstaff of Boston University, who was not involved in the work.
For just about his entire life, Ron Smith has been a subject of a scientific inquiry. At birth, in 1972, he was studied by scientists, and then assessed again at age three to document his physical fitness, mental health and intelligence.
