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 ... >>

Random news from the Archive New chemical element 11.05.2014 The Helmholtz Center for the Study of Heavy Ions (Darmstadt, Germany) synthesized four ununseptium atoms, thereby confirming the existence of the 117th element of the periodic table. Ununseptium was first obtained at the Russian Joint Institute for Nuclear Research (JINR) in 2009. For the synthesis of the 117th element, a target of the 97th element, berkelium-249, obtained at the Oak Ridge National Laboratory (USA), was bombarded with calcium-48 ions at an accelerator. Ununseptium formally belongs to the halogens, but its chemical properties have not yet been studied and may differ from those characteristic of this group of elements. During a long (more than half a year) experiment, 6 events of "birth" of the 117th element were registered. The decay properties of the isotopes of ununseptium and its daughter products - the isotopes of elements 115, 113, 111, 109, 107 and 105 - are direct experimental proof of the existence of "islands of stability" of superheavy nuclei. Despite the achievement of Russian scientists, the existence of the 117th element was not recognized by the International Union of Theoretical and Applied Chemistry, since it required independent confirmation. Now this element has been synthesized by German researchers. The heaviest natural element - uranium - has an atomic number (the number of protons in the nucleus) 92. Elements heavier than uranium are obtained in nuclear reactors, the heaviest of them is fermium with number 100. All heavier elements were obtained at accelerators in reactions accelerated to high energies ions with target nuclei. As a result, nuclei of superheavy elements are formed, which exist for a very short time, and then decay. Thus, the half-life of ununseptium is 78 milliseconds. Note that from 2000 to 2010 physicists from the Flerov laboratory at the Joint Institute for Nuclear Research in Dubna, near Moscow, have synthesized for the first time the six heaviest elements with atomic numbers from 113 to 118. Two of them have already been officially recognized by the International Union of Pure and Applied Chemistry and have received the names flerovium (114) and livermorium (116 ). The application for the discovery of elements 113, 115, 117 and 118 is currently under consideration.
