Focus Description:

The magician easily "magnetizes" the hands of the viewer.

Focus secret:

The magician tells his partner to clench his hands very tightly at chest level. Then the magician makes 3 turns around his hands with his hands, "conjures", then snaps his hands. Everything, the viewer can unclench his hands - they are magnetized!

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 ... >>

Plant Growth Control with Light 04.07.2020

Scientists from Germany and the UK have found a way to control various plant processes - such as growth - using optogenetics. By exposing different colors of light, scientists can turn different plant genes on and off.

Previously, it was not possible to use optogenetics in research with plants because plants naturally respond to light as they grow. Therefore, any genetic switches controlled by light, one way or another, remained permanently active.

Experts have found a way to deal with this problem. They developed a special system PULSE (Plant Usable Light-Switch Elements), which allows you to control various cellular processes in plants using light. The project links two current topics in biology - optogenetics and synthetic biology.

Thanks to the new tools, it is now possible to use, for example, red light to trigger gene expression at a certain point, while ambient white light can be used as a "switch" to reverse the process. In this case, the procedure can be repeated any number of times. This process is non-invasive and easily reversible - unlike the use of chemicals or drugs.

Scientists can use this system to control the physiological responses in plants: their immune response and possibly their development, growth, hormone transmission, and stress responses.

The researchers hope that in the future their technology will allow them to regulate how plants grow and how they flower and adapt to their environment, ultimately increasing yields.
