We all live in a big bubble, and it created thousands of stars in the night sky.
A bubble spanning 1000 light-years surrounds our solar system, where thousands of young stars are born. It is called a local bubble and is produced by the gorgeous death of stars-supernova bursts-providing conditions for the formation of new stars. However, in the 50 years since its discovery, due to the limitations of observation technology, the overall image of the local bubble has been blurred to astronomers. Recently, someone has finally unveiled its mystery.

Medical science Treatment of articular cartilage injury with piezoelectric device Osteoarthritis is a very common disease. As a result of trauma or aging, articular cartilage will be damaged, resulting in a direct impact on the bone, causing severe pain. At present, there is no effective cure for osteoarthritis. Recently, scientists have used a piezoelectric device to effectively improve the healing of knee cartilage defects in rabbits. The study has been published in the journal Science Translational Medicine.
