A team of researchers from Yonsei University in Korea and Hokkaido University in Japan, has developed a metamaterial device that allows for much better than normal sound transfer between water and air. In their paper published ...
It is one of the great ironies of biochemistry: life on Earth could not have begun without water; yet water stymies some chemical reactions necessary for life itself.
