Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Consciousness as a balance of interaction between neurons 31.01.2016

Scientists from the Institute of Medical Psychology (Germany) have shown that brain activity in consciousness and in unconscious states is seriously different. This means that our consciousness is based on a delicate balance of interaction between neurons: as soon as it is disturbed, consciousness escapes.

At the moment of waking consciousness, there is a flurry of constantly changing activity in the brain, functional MRI showed the presence of many overlapping networks of activation. When a person was unconscious under anesthesia, the number of networks was significantly reduced, and activity practically did not change its character throughout this period.

The results suggest that in the brain there is an optimal level of connectivity between neurons, which creates the maximum possible number of interactions. However, there can't be too many of them either: if every neuron in the brain is directly connected to every other neuron, the brain will become too homogeneous, and one signal will become indistinguishable from another. Consciousness means this point of balance, in such a state between chaos and complete stability, the brain can effectively engage in research.

"It's like cars driving around a city. If you always drive a car on exactly the same route from point A to point B and back, then at the end of the day you will not know how the city works. But you will explore all possible routes and parts of the city , you will get a map that is very close to the real map of the city," said Enzo Tagliazucchi, leader of the study.
