Focus Description:

In this trick you will learn how to make a chemical snake.

Focus secret:

Soak a piece of dry fuel (for example, tablets containing urotropin) for several minutes with a solution of ammonium nitrate and dry. This operation must be repeated again. Tablets cannot be kept in solution for a long time, as they dissolve. With the pills themselves, the trick can turn out badly, so it’s better to cut cubes out of the pills.

If we now set fire to the dried piece, then ammonium nitrate, decomposing with the release of a large amount of gases, will swell the combustible mixture, turning it into a black loose snake. If such a "snake" is carefully taken by the head, it can easily be twisted into a spiral.

Be especially careful when demonstrating this trick.

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.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

Bad fat becomes good 10.05.2013

For a long time, scientists have dreamed of turning unwanted white fat cells into brown ones, which help to “shed” excess weight. Scientists at the University of Bonn are one step closer to that goal by discovering a "switch" in mice that stimulates fat burning.

On Earth, a huge number of people suffer from overweight, which is associated with the accumulation of so-called white fat, which retains excess nutrients. Brown fat cells are exactly the opposite: they burn excess energy. Scientists have spent years trying to figure out how to turn unwanted white fat into usable brown fat. The researchers may have found a way to shed extra pounds by simply turning unwanted fat into "good" fat.

Scientists at the University of Bonn have discovered a microRNA 'switch' in mice that is important for the formation of brown fat cells. MicroRNAs are able to very quickly and efficiently regulate gene activity. A specific miRNA 155 inhibits a specific transcription factor that controls brown fat cells. Moreover, the transcription factor works like a switch: when the expression of microRNA is high, the production of brown fat is blocked, and when it is low, on the contrary, the production of brown fat increases and, accordingly, the body loses excess weight.

It turns out that microRNA 155 functions as a brown fat antagonist. Simply put, as long as there is a certain amount of microRNA 155 in the body, the production of brown fat necessary for weight loss is blocked. This, of course, complicates the development of therapy - if it were the other way around, then for weight loss it would be enough to introduce an excess amount of microRNA 155. Nevertheless, scientists believe that they will be able to develop a drug that will reduce the amount of microRNA 155, especially since in overweight people, an increased content of this miRNA was found.
