Pigeons have surpassed mammals in brain efficiency.

A gram of pigeon brain consumes, on average, 2.5 times less glucose than the brain of mammals of comparable size, and 3.5 times less per neuron, the German scientists found. The reason for such a high energy efficiency of avian neurons has not yet been precisely determined, but, most likely, the matter is in the histological features of the nervous tissue and the temperature of the brain.

Men's brains shrink when they become fathers, scientists have found.

The study involved forty volunteers from two countries who were preparing to become fathers for the first time. They underwent MRI examinations before their partner's pregnancy, during it, and also several months after the birth of the child. The results showed that in fathers, unlike mothers, the structure of the limbic system of the brain, which is responsible for motivation and internal reward, does not change with the birth of a child. But the restructuring occurs in the cerebral cortex, affecting the visual cortex and areas associated with the network of the passive mode of the brain. Perhaps the changes in the brain are designed to help fathers more easily recognize their child and be more willing to respond to him, the authors of the study say.

In Japan, they released the NFT to reward officials.

NTU scientists have introduced a robot to prevent falls in the elderly.

The robot consists of a wheeled battery base that is connected to a padded seat belt worn around the user's hips. While the person walks, the robot follows him. Using a depth-sensing camera and other sensors, it is able to recognize control movements that indicate a sudden loss of balance by the user. When this happens, it stops and fixes the straps, preventing the user from falling. In addition to assisting in everyday life, the robot can be used in rehabilitation medicine, supporting the user when he learns to walk again. It is reported that in the near future the MRBA will be improved to an industrial prototype.

Thus, the Celestial Empire actually got rid of the technological dependence of Taiwan, Nvidia and other guys. We are waiting for the appearance of video cards on the market.

People begin to hate each other when they are too cold or too hot.

Temperatures below +12 °C and above +21 °C can have a negative impact on the psyche and provoke aggression in social networks. Scientists analyzed 4 billion tweets written by Americans in 2014-2020. Artificial intelligence compared the presence of hate speech in the post with the temperature outside the window. The least aggressive tweets were written at temperatures between +15°C and +18°C. When it was warmer than +30 °C outside, there was much more hatred on the Internet: in all climatic zones and social communities.

New Delhi will ban fireworks from October to January.

This measure was introduced to reduce the level of air pollution. These months are especially difficult - the metropolis is shrouded in smoke from burning stubble, dust and car exhaust. In addition, on October 24, the Diwali festival of lights takes place, and the city is filled with smoke from the launch of pyrotechnics. Some Hindus condemn the city government's decision. They believe that the ban on fireworks during Diwali restricts their freedom of worship.

From blows to the head, the skull becomes stronger.

After blows to the head, the bones of the skull become thicker and stronger - this is how the body prepares for new injuries and protects the brain. These conclusions were reached by Australian scientists in the course of experiments on rats. How much thickening of the bones protects the brain is not yet clear. More research is needed.

Scottish scientists have come up with a hearing aid that reads lips even through a mask.

For this, artificial intelligence is used - the radar scans the movements of the lips and determines which sound they are characteristic of. For open faces, the accuracy is 95%, for closed faces, 83%. The scanner will help people hear well both in normal conditions and in noisy environments. Prior to this, the effect of a cocktail party for the hearing impaired was provided by devices that read lips with the help of a camera. But the video recording of the interlocutors could violate their privacy.

By 2050, 16% of people worldwide will be over the age of 70.
