India has developed nanobots that destroy bacteria inside the teeth.

The idea is that iron-coated silicon dioxide helical structures can change position and move in space under the influence of magnetic fields. More importantly, they can be either inserted into living tissues or removed after a treatment session. Toothbots can penetrate into the dentinal tubules to a depth of up to 2000 micrometers, after which a change in the parameters of the magnetic field causes them to heat up. The excess heat destroys the bacteria, then the nanobots are removed. Experiments on individual teeth were successful, and now Indian scientists are working to create a new special tool for dentists based on their technology.

The Israelis have created a smart bee hive that can prevent the global extinction of bees

To neutralize the threat, the Israelis proposed a prototype of the "smart beehive" Beehome. The hive is equipped with precise robotic systems, computer vision and artificial intelligence. This allows you to follow the bees and their needs in real time. About the same thing beekeepers have been doing for the last 150 years. A smart hive instantly detects possible threats to the bee family (for example, the presence of pesticides or pests) and immediately activates defense mechanisms.
