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 We smell not only with our nose, but also with our tongue. 02.05.2019 Scientists from the Monell Center (USA) came to such an interesting conclusion. They found that olfactory receptors found in the nasal cavity are also found in taste cells found on the tongue. This discovery could lead to the development of odor-based taste modifiers that could help fight nutrition-related diseases such as obesity and diabetes. Smell provides detailed information about the taste quality of food, and taste, by which the tongue detects sweet, salty, sour, bitter molecules, acts as a "gatekeeper" for assessing the nutritional value and potential toxicity of food. Until now, these two systems were considered independent systems that did not interact with each other until signals from taste and olfactory receptors arrived in the brain. It turned out that they interact with each other at the very first stage. Cell biologist Mehmet Hakan Ozdener and colleagues used methods developed at the Monell Center to culture living human taste cells (receptor cells located in the taste bud). Using genetic and biochemical methods to study taste cell cultures, the researchers found that these cells contain many key molecules that are present in olfactory receptors. Then, turning to calcium imaging, they showed that cultured taste cells respond to odor molecules in a similar way to olfactory receptor cells. Other experiments by scientists at the Monell Center have also confirmed that a single taste cell can contain both taste and smell receptors.
