Focus Description:

On the table is a small box with narrow - about 2 cm - sides. Take the thread with the beads strung on it out of your pocket and shift it several times from hand to hand so that everyone can see that the beads are strung freely. Tell the audience that you will make the beads stand upright.

Pick up the box and show the audience that it is completely empty. Lower the thread with beads into the box, take the box in your hand, make a few passes over it with the "magic wand", and the thread with beads will rise from the box.

Focus secret:

There is a small hole in the bottom of the box. The beads are strung in such a way that there are several smaller beads below that could pass into the hole. When you put the beads in the box, the smallest of them are passed through the hole. Take the box between your thumb and forefinger and turn your hand with the palm facing you. Press the tail of small beads with your middle finger to the palm of your hand and pull the thread. A column of beads instantly rises above the box.

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 ... >>

Fullerenes can be neutralized 13.01.2005

Recent studies have shown that fullerenes - round hollow molecules, consisting of several tens of carbon atoms, can damage the cells of living organisms.

It is believed that these carbon balls, interacting with the fatty substances of the cell, cause the formation of free radicals. Active molecules of radicals break the cell, since its membrane consists of two layers of fatty substances.

Now the experiments of biochemists from Rice University in Houston (USA) allow us to hope that the toxicity of hollow supermicroscopic balls can be largely removed by changing the composition of their surface. By attaching hydroxyl groups to 24 of the 60 carbon atoms that make up the fullerene molecule, scientists have reduced toxicity to human skin cell culture by seven orders of magnitude. Without such surface modification, fullerenes, even at low concentrations, kill skin cells.

This discovery is important for practice, since fullerenes are increasingly used in technology - as an additive to lubricating oils, as a component of batteries and fuel cells. They can get into the external environment, and from there - into the body of humans and animals. Hollow fullerene molecules are supposed to be used as ultra-small pills, filling them with medicines and injecting them into the patient's blood.

On the other hand, the authors of the study believe that by introducing other additives into fullerenes, on the contrary, it is possible to increase their toxicity and use such molecules against cancer cells. True, they emphasize that the behavior of fullerenes in a laboratory cell culture may differ from their effect on a whole living organism.
