In the early morning of July 4, a citizen called the police and reported that someone was calling for help from the signal tower opposite the bus stop at the entrance of Qingsong Highway outside Qichang Road in Jiading District, Shanghai. After receiving the call, the fire department rushed to the scene to deal with it immediately. Unexpectedly, it turned out that two junior high school students climbed up the signal tower about 25 meters above the ground.

On July 26, Nature published this night vision technology that can see daytime scenes in the dark as a cover article. Bao Fanglin, a research scientist at Purdue University, is the first author of the paper. After the publication of this paper, which took four years to complete, Bao Fanglin was not overly surprised. He admitted that many emotions had been gradually smoothed out during the two-year and three-round review process. Indeed, he added more than 80 pages of explanations for the first round of comments alone, and the second round of comments allowed him to develop 10 application scenarios.
