What are some examples of technological innovation?

Examples of scientific and technological innovation: 1. Scientists in China realize the world's first human lung regeneration. Dozens of stem cells taken from patients' bronchial brushes were expanded tens of millions of times in vitro and transplanted into patients' lung lesions.

After three to six months of proliferation, migration and differentiation, these stem cells gradually formed new alveolar and bronchial structures, and then completed the repair and replacement of damaged lung tissue. Professor Zuo Wei from Tongji University School of Medicine took the lead in using adult lung stem cell transplantation technology in the world and successfully achieved human lung regeneration in clinic.

2. Successfully cloned hybrid rice seeds. From June 2065438 to October 2009 10, the team of Wang Kejian, the State Key Laboratory of Rice Biology of China Rice Research Institute, established a rice apomixis system by using gene editing technology, successfully cloned hybrid rice seeds, and realized the stable inheritance of hybrid rice characters to the next generation for the first time. This achievement was published online in the journal Nature Biotechnology.

3. After the successful sea trial of "Tian Kun", the dredging industry in China turned to deep blue. Tian Kun made a sea trial on June 8th at 20 18- 1 1. During this period, Tian Kun completed many tests, such as speed measurement, ship stopping test, steering test, mooring test, steering gear test, ship power system function test and other auxiliary system function tests.
