Scientists have learned how to make computer chips from mushroom skins.

Such a chip, according to scientists, is much easier to dispose of when it has served its useful life. After testing the resulting chip, the team concluded that the skin was almost as good as traditional plastic bases. After 2,000 bends, not a single crack formed on it. But there are still difficulties. For example, in the production of such chips, additional tests must be carried out to make sure that the skin works as it should. Nevertheless, scientists consider their development promising and plan further research.

Up to 1.35 billion people could lose their hearing due to too loud music on headphones.

The researchers analyzed more than 30 scientific papers on this topic over the past 20 years. In the studies analyzed by scientists, a total of about 20 thousand people participated. It turned out that in 24% of cases, listening to music with headphones can be called dangerous. In the case of concerts, this figure reaches 50%. The researchers also found that listening to loud music was associated with "changes in hearing thresholds." This is due to the fact that sensory cells are damaged in humans, and it takes years to restore them.

The causative agents of leprosy can speed up the recovery of the liver.

Scottish scientists observed the South American armadillos and found that one of the strains of leprosy (leprosy) penetrates into the animal's liver and accelerates its growth. Perhaps the bacterium can be used to regenerate this organ.

Scientists decided to create a protocol of actions in case of a meeting with aliens.

John Elliot, a researcher at the Scottish University of St. Andrews, decided to unite around himself scientists, amateur ufologists, lawyers, journalists and representatives of other professions to create an up-to-date protocol. The Post-Detection Hub will focus on scanning signals and looking for potential extraterrestrial messages, as well as combating misinformation on the subject. The document will prescribe how to respond to alien signals and interact with them in case of contact.

Supercar Rimac Nevera set a speed record for electric vehicles.

The car was dispersed to 412 kilometers per hour. Up to 100 kilometers, the car accelerates in less than 2 seconds, and is currently the fastest on the planet.

A new definition of the second will appear in the SI system in 2026-2030.

The current definition of the second associates it with a certain number of transitions (9.192 million) between energy levels that cesium-133 ions make inside atomic clocks when interacting with electromagnetic waves. In recent years, the quality of measuring instruments and the accuracy of atomic clocks have greatly improved. This makes scientists think about the introduction of a new concept of a second, based on other measurement methods. Nine approaches, based on different types of atomic clocks and frequency standards, are currently claiming this role.

Black Mamba.

The black mamba is the fastest snake in the world. It is capable of speeds up to 20 km / h, if the need arises. The length of the black mamba can reach three meters. Contrary to their name, black mambas are by no means black. They got their name from the black color of their mouths, which they open wide before attacking. In Africa, as a result of the expansion of agricultural land, people have invaded the lands where black mambas live, but the snakes do not go anywhere, so attacks on peasants are becoming more common. Every year, eight to ten thousand people die from the bite of a black mamba.

Startup Move AI came up with motion capture technology that works without sensors.

A specially created neural network will turn the recorded video into a finished animation with the ability to import it into any engine, and therefore into any virtual world. To transfer yourself to the virtual world, an ordinary camera is enough.

Nike opens a store in the metaverse.

They will trade virtual and real sneakers there. They are launching a project together with the Swoosh platform, where the first collection will be shown - at the beginning of 2023. So far, they say, they cannot predict how buyers will perceive the novelty.

In France, surgeons have grown a nose on a woman's hand and transplanted it onto her face.

A patient from Toulouse lost a large part of her nose in 2013 after being treated for nasal cancer with radiotherapy and chemotherapy. The woman experienced an unsuccessful attempt to reconstruct her nose with a skin flap graft and had difficulty wearing facial prostheses. However, thanks to a revolutionary procedure, a new nose was grown on her forearm and transplanted onto her face.

Happiness in money!

Scientists have found that happiness is in money. They conducted an experiment: 200 participants were given $10,000 in their hands, and nothing was given to the control group of 100 people. The lucky ones had to spend the gift money in the next three months. All 300 participants in the experiment kept a diary - who has a mood, do they live well and do they enjoy every day they live? It turned out that $10,000 significantly increased the feeling of joy and happiness among those who received it compared to those who did not get the money.

The oldest evidence of life on Earth has been found.

Rock formations in Western Australia in the Dresser Formation, 3.5 billion years old, have been found to be the oldest evidence of life on Earth. These rocks are stromatolites. Usually they consist of layered rocks, which can be formed either as a result of the vital activity of microbial colonies, or as a result of chemical reactions between the rock and the environment. They can help scientists understand when and where life first arose on Earth, but determining the exact origin of stromatolites is difficult.

Record fine in the case of illegal surveillance.

Google has agreed to pay a record fine in the case of illegal surveillance of users. It's all about the murky politics of corporations, where to turn off surveillance of yourself you need to climb into the jungle of settings, and even then this does not always work. For this, 40 US states fined Google half a billion dollars. And they were obliged from 2023 to make the functions of disabling tracking more transparent.
