● How to repair tooth enamel has always been a problem in the field of bionics. Recently, the artificial tooth enamel research led by mainland scholars has made a new breakthrough, and composite materials with similar structure and performance to natural tooth enamel are expected to become a new generation of dental restoration materials. In this study, a multi-scale enamel-like composite synthesis route based on "macro synthesis and controllable assembly of nanostructured units" was designed, and the controllable preparation of tooth enamel composites with similar enamel structure was realized.

● According to the Physicists Organization Network reported on the 5th, an international research team has confirmed that a "microlensing" event they witnessed in 2011 was caused by a lonely black hole roaming freely in interstellar space, which is the first time scientists have ever observed such a black hole. Moreover, for the first time, scientists have measured the mass of the black hole to be about 7 times the mass of the sun, and the speed of travel is about 45 km/s.
