●Recently, the scientific and technological innovation team of the Chinese Academy of Agricultural Sciences used 850 Chinese horse genetic resources collected and preserved in the National Domestic Animal Germplasm Resource Bank to successfully analyze the main gene mutation of Chinese horse body high variation, and found that the mutation first appeared in the ancient horse population during the Mongolian Empire 2,300 years ago, and then quickly expanded to all modern horse populations in Eurasia. This research has laid an important scientific foundation for the conservation and breeding of horse resources in southwest China. (Source: Science and Technology Daily)

●According to the Physicists' Organization website on the 22nd, an international research team composed of scientists from the United States and France wrote in the latest issue of Nature Astronomy that they used data provided by the Hubble telescope to directly detect the characteristics of the magnetic field around an exoplanet for the first time. The researchers pointed out that the magnetic field plays a vital role in protecting the atmosphere of the planet, so detecting the magnetic field of the exoplanet is an important step to better understand these alien worlds.
