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.

When there is a lot of stress, plants will scream, and it will be super loud.
Don't think that plants are quiet and silent under any blow. Actually, it's our ears. We don't hear their voices.

New technology The world's smallest miniature battery Nowadays, electronic devices such as computers are becoming smaller and smaller, so there is an urgent need to develop smaller micro-batteries compatible with the devices. At present, the integration of micro-battery mainly uses wet chemical method, in which electrodes, adhesives and other materials need to be treated as mud, and the area of the battery integrated by this method is often more than 1 square millimeter. Recently, a study published in Advanced Energy Materials produced miniature batteries less than 1 square millimeter and smaller than a grain of salt using a method called Swiss roll.

Is the Arctic "dormant" methane or "awakened", and the sixth mass extinction climax is approaching?
Introduction: About 65 million years ago, the dinosaurs, the biological overlords on the earth, were tragically extinct, so there were a lot of vacancies in the ecological chain of the earth. It stands to reason that mammals should quickly rise to become the new overlords of the earth at this time, but That wasn't the case, as dust and carbon dioxide levels in the air surged after the planetary collision that killed the dinosaurs, and temperatures began to mess up.

Humans dived 10,000 meters underwater in the Mariana Trench, what did they find? Here comes the truth
Introduction: With the continuous progress of science and technology in my country, there have been many satellites launched by humans in space now. Through these satellites, we can better observe every place on the earth, but from the satellite we can only see the general situation of the earth's surface, more for the land, but there is no way to use the interior of the ocean. Satellite to detect. Now we usually rely on submarines to explore the ocean.
