In this edition of Tech It Out, CGTN visited a chemistry lab at Zhejiang University to find out how scientists are bending the laws of nature to regenerate tooth enamel, the hardest tissue in the human body.

We also take a look at a new smart material that can memorize shapes and review the major scientific news stories of the past two weeks, including NASA's latest findings on solar wind and thousands of ice balls winding up on a Finnish beach.
