The company Neuralink, founded by Elon Musk, received permission for a second operation to implant a neuroimplant into the human brain after the first was successful. After this operation, a paralyzed volunteer spoke about how the chip helped him develop telekinetic abilities, making a significant difference in his daily life.

Noland Arbo, who became disabled after an accident in 2016, noted that thanks to Neuralink, he can now control his computer with his mind, play interesting games and cope with everyday tasks. Previously, he had to use a stylus held between his teeth to do this.

Modern technologies in the field of brain interfaces open up new opportunities for people with speech impairments. The University of California recently unveiled its latest project – an implant that helped a paralyzed man regain the ability to speak not only his native Spanish, but also English.

This man, whose life was changed by a stroke, was faced with the loss of his ability to speak due to damage to his brain stem. His cognitive abilities were not affected, but his control of his vocal apparatus was severely limited. That is why he agreed to become a participant in a study with a neural interface.

In Japan, the problem of excess salt intake has reached critical levels, with Japanese adults consuming approximately twice the daily recommended amount for health. To solve this problem, scientists from Meiji University have created a unique electric spoon that can add a salty taste to ordinary food.

Professor Homei Miyashita demonstrated this amazing invention, which works thanks to a weak electric field that concentrates sodium ions on the silt, enhancing the perception of salinity. Lightweight and convenient, the spoon weighs only 60 grams and is powered by a rechargeable lithium battery, making it accessible to everyone.

Recent research suggests that rivers in Alaska are suffering from pollution, causing their water to turn rusty and orange, reminiscent of vinegar. Scientists paid attention to 75 streams that have changed their color and chemical composition over the past decade.

Water samples showed high levels of various metals such as iron, zinc, copper, cadmium and nickel, indicating serious environmental problems. The reason for these changes, according to scientists, is an increase in temperature, which caused the melting of permafrost and the migration of metals into water sources.

The James Webb Space Telescope has made a significant discovery by capturing images of galaxies that emerged just 400 to 600 million years after the Big Bang, early in cosmic history. Thanks to its powerful infrared capabilities, the telescope was able to penetrate deep into time and space, allowing us to see the first galaxies forming.

The telescope’s revealing images show three galaxies that formed between 13.2 and 13.4 billion years ago during the birth of the cosmos. These unique images represent the first glimpses of young clusters that have not previously been accessible to astronomical observation, generating significant interest in the scientific community.
