CTOnews.com, December 16 (Xinhua) according to the official Wechat account of Science Daily, on December 16, 2022, Science magazine released a list of this year's top 10 scientific breakthroughs. Among them, the development of perennial rice varieties in China was selected on the list.

In November 2022, relevant teams inside and outside the United Nations of Hu Fengyi team of Yunnan University in China published a research paper entitled "Sustainable Productivity and productive potential of perennial Rice" in the internationally renowned academic journal Nature Sustainability. a research brief entitled "perennial rice change promoting sustainable agriculture" was also published at the same time.

The team's perennial rice 23 (PR23) can be harvested continuously with no-tillage for 3-4 years, that is, it does not need to buy seeds, raise seedlings, plow and transplant from the second season, but only needs two production links of field management and harvest, so as to save production costs and reduce labor. It is a milestone in the field of interspecific hybrid cultivation of perennial food crops.

In addition, after numerous setbacks, 20 years of development, 10 billion dollars and 1.5 million kilometers of dangerous space travel, the new James Webb Space Telescope (JWST) has finally opened its golden infrared eyes to glimpse the universe and its unfathomable past in amazing and unprecedented detail. To commemorate this feat, Science magazine selected JWST's flight as the top scientific breakthrough in 2022.

Space telescopes are unhindered by the Earth's atmosphere and provide an undisturbed view of the universe around the Earth. However, unlike its predecessor, the Hubble Space Telescope, JWST can capture infrared light, including light from the first stars and galaxies.
