Rumor that the giant panda "Yangyang" in the United States foams at the mouth and gnaws on the wall skin with hunger?
Truth: Recently, it has been reported on the Internet that the giant panda "Yangyang" in the United States has "foamed at the mouth", "vomited", and "gnawed on the wall skin with hunger", which has attracted attention. In this regard, the Chengdu Giant Panda Breeding Research Base issued a response on May 11, saying that the "Yangyang" and "Lunlun" families are currently in good health. The "foaming at the mouth" in the online video is actually the white foam that appears on the side of the mouth of the giant panda when there is a lot of exercise or walking; "Vomiting" is actually a phenomenon in which the mucus secreted by the mucus gland unique to the lining of the digestive tract of the giant panda wraps the feces and the excess part accumulates into a clump in the intestine and then excretes from the body. "Hungry to bite the wall" is actually a common behavior for giant pandas to explore the environment through sniffing, biting, rubbing, scratching and other behaviors. At present, the "Yangyang" and "Lunlun" families have not been "underfed", please rest assured. At the same time, in accordance with 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 is going through the relevant procedures.

The red aurora that has recently occurred on the mainland is a "false aurora"?
Details: On the evening of May 11, gorgeous aurora lights appeared in the sky in Xinjiang, Inner Mongolia and other places on the mainland, and even parts of Beijing. But unlike the aurora seen in the polar region in the past, most of the aurora is green, and the aurora that occurs on the mainland is mainly red. In fact, the aurora doesn't just come in one color, but is layered like a cocktail.
Auroras are a "by-product" of geomagnetic storms, and when high-energy particles produced by solar activity meet the Earth, they will collide with the Earth's atmosphere at high speed, and this process will produce microscopic energy exchange. Take the oxygen atoms in the atmosphere as an example, they will receive a share of energy from the impact, but due to the characteristics of the electrons outside the nucleus, only a certain amount of energy can be contained between the electrons and the nucleus, and the excess part will be released again, and the form of release is luminescence.
According to the schematic diagram of human observation of the aurora drawn by the magazine "China National Geographic", it shows that above 300 kilometers, the aurora is mainly light red; 200-300 km is dominated by dark red; 100-200 km is mainly green; Below 100 km, it is blue, purple or a combination of colors.
Therefore, the desire to see green aurora on the continent will not be possible until the solar activity is more intense and high-energy particles bombard the atmosphere about 100 kilometers above the ground in the mid-latitudes. (Source: Science and Technology Daily)
