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 ... >>
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 ... >>
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 ... >>

Augmented Reality Contact Lenses
12.03.2023
Korean developers, in collaboration with scientists, have introduced contact lenses that can work as an augmented reality screen.
Developers from the Ulsan National Institute of Science and Technology assure that the operation of such lenses does not require a large amount of energy. The gadget can fully display white, blue and green spectra.
"The main disadvantages of known AR devices are the price, experimental technologies and bulky design. Our contact lenses are inclusive, comfortable and can be worn for several hours without problems," the scientists note.
The lenses were based on electrochromic (color-changing) displays based on Prussian blue pigment. In the pilot version, the lenses contained limitations in the display of words or pictures, since at first it was difficult for scientists to apply microcircuits to an accessory using the galvanization (electronic current) method.
In the new version, experts have replaced this technique by printing chips and displays on a 3D printer. As a result, the team received a miniature AR screen. Experts tested its action experimentally - the screen indicated the route to the user with lenses through GPS coordinates, which the person received in real time. The lenses helped the person to reach their final destination.
