“Science” magazine announced the top ten breakthroughs in 2022

According to the news on December 16, according to the WeChat account of Science Daily, on December 16, 2022, the American “Science” magazine announced the list of the top ten scientific breakthroughs of the year. Among them, the development of China’s perennial rice varieties was selected for the list.

In November 2022, Hu Fengyi’s team from Yunnan University of China, together with relevant domestic and foreign teams, published a research paper entitled “Sustainable Productivity and Production Potential of Perennial Rice” in the internationally renowned academic journal “Nature Sustainability”, and simultaneously published a research paper titled “Sustainable Productivity and Potential of Perennial Rice”. Research brief for “Perennial rice transformation for sustainable agriculture”.

The team’s perennial rice 23 (PR23), once planted, can be harvested continuously for 3-4 years without tillage, that is, from the second season onwards, there is no need to purchase seeds, raise seedlings, plow fields, and transplant other production links, and only need two days of field management and harvesting It is a milestone event in the field of perennial food crops based on interspecific hybridization, which saves production costs and reduces labor.

And, after numerous setbacks, 20 years of development, a colossal $10 billion cost, and a dangerous 1.5 million-kilometer journey into space, the new James Webb Space Telescope (JWST) has finally opened its golden infrared eyes for awe-inspiring The universe and its unfathomable past are glimpsed in unprecedented detail. To commemorate this feat, the US magazine Science selected JWST’s flight as the top scientific breakthrough of 2022.

Unobstructed by Earth’s atmosphere, the space telescope provides an undisturbed view of the universe around Earth. However, unlike its predecessor, the Hubble Space Telescope, the JWST captures infrared light, including light from the first stars and galaxies.

Science magazine’s top 10 breakthroughs for 2022:

• James Webb Space Telescope (JWST)
