Rumor: "Yangyang", a giant panda in the US, foams at the mouth and gnaws at the wall when hungry?
Truth: Recently, the Internet reported that the giant panda "Yangyang" in the United States appeared "foaming at the mouth", "vomiting", "hungry to gnaw on the wall" and other situations, causing concern. In this regard, the Chengdu Research Base of Giant Panda Breeding replied in a document on May 11 that "Yangyang" and "Lunlun" are in good health. The "foaming at the mouth" in the online video is actually the foaming at the mouth of giant pandas when they are moving a lot or walking a lot; "Vomiting" is actually the phenomenon that the excess part of the mucus secreted by the unique mucus gland in the inner lining of the digestive tract of the giant panda gathers in the intestinal tract and is discharged out of the body after wrapping the feces, and the giant panda recovers as before after the end of mucus excretion; "Hungry to gnaw on the wall" is actually a common behavior of giant pandas to explore the environment through sniffing, gnawing, dawdling, scratching and other behaviors. At present, the "Yangyang" and "Lunlun" families have not suffered from "insufficient food". Please rest assured. At the same time, according to the agreement between China and the United States, the return procedure of the giant pandas "Yangyang" and "Lunlun" in the United States has been started and the relevant procedures are being handled.

Science popularization: Is the red aurora in China recently a "false aurora"?
Details: On the evening of May 11, brilliant aurora appeared in the sky in Xinjiang, Inner Mongolia and other places in China, and even in some areas of Beijing. But unlike most of the auroras seen in the past in the polar region, which are mostly green, the auroras in China are mainly red. Can you see a "false aurora"? In fact, aurora is not only one color, but will be layered like a cocktail.
Aurora is a "by-product" of geomagnetic storms. When high-energy particles generated by solar activities meet the Earth, they will collide with the Earth's atmosphere at a high speed. This process will generate microscopic energy exchange. Take the oxygen atoms in the atmosphere for example, they will receive a share of energy from the impact, but due to the characteristics of electrons outside the atomic nucleus, only a certain amount of energy can be held between the electron and the atomic nucleus, and the excess part will be released again, and the form of release is luminescence.
According to the schematic diagram of human observation aurora drawn by China National Geographic magazine, the aurora is mainly light red at more than 300 kilometers; 200-300km is mainly dark red; 100-200km is mainly green; Below 100km, it is blue, purple or a mixture of multiple colors.
Therefore, if you want to see the green aurora in China, you will not be able to see it until the solar activity is more intense and high-energy particles bombard the atmosphere in the mid latitude region about 100 kilometers from the ground. (Source: Science and Technology Daily)
