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 ... >>

The cleanest place on earth 02.06.2020

Scientists from Colorado State University have found a region of the atmosphere on Earth that has not been affected by human activity.

The study found that the cleanest air on Earth can be found in the Southern Ocean south of 40 degrees south latitude. A group of scientists have discovered that the planetary boundary layer (the lower layer of the planet's gaseous envelope - ed.), which feeds the clouds over the Southern Ocean, is absolutely clean. No aerosols were found there, which are formed as a result of anthropogenic activity and are carried by the wind over great distances.

According to scientists, weather and climate are complex processes that bind together every part of the world, and therefore it is so difficult to find a corner on Earth that is not affected by people. Creidenweiss and his team hypothesized that the air over the remote Southern Ocean surrounding Antarctica would be the least affected by people and dust from the continents.

The samples were collected during field research, the ship with scientists passed south from Tasmania to the Antarctic ice edge. Air samples were taken in the marine boundary layer, which has direct contact with the ocean.

With the help of DNA sequencing, it turned out that the microorganisms in the air samples were local, brought there from the surrounding ocean. The air over the Southern Ocean was so pure that the researchers did not even have enough DNA to work with.
