Focus Description:

The participant is asked to fold the notebook sheet into 9 squares. Write a name in each square, and your name in the middle square. Carefully break the squares along the lines and mix (remember the name that was written in the middle of the sheet). The magician must move his hand over the pile and get the right piece of paper.

Focus secret:

The leaflet that was in the middle will be torn off on all sides.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Smallest mobile life form created 10.12.2022

In a groundbreaking study, Japanese researchers at Osaka Capital University have created the world's smallest mobile life form. They introduced seven bacterial proteins into a synthetic bacterium. Eventually, she was able to move on her own. As the biologists explain, the study provides a better understanding of evolution and the origin of organisms' mobility.

For the experiment, scientists used a synthetic bacterium syn-3. A completely artificial life form was created 12 years ago when scientists created a microorganism from a synthetic chromosome consisting of four chemicals. Then other researchers added the syn3 genome to the organism, which allowed it to grow and divide. However, he remained motionless.

As part of a new study, scientists have introduced seven genes encoding proteins and "responsible" for the swimming functions of the Spiroplasma bacterium. This is a small natural organism in the form of a long spiral. As a result, syn3 also changed its usual round shape and became similar to Spiroplasma. He was also able to swim using the "change the direction of the helix" technique, just like the original bacterium.

"Our floating syn3 can be called the 'smallest mobile life form' capable of moving on its own," said Professor Makoto Miyata, co-author of the study. "The results of the study will help us better understand the evolution and origin of cell motility."

The study of the smallest bacterium in the world with the smallest functional motor apparatus will be useful for developing the movement of microrobots that mimic the work of cells or motors based on proteins.
