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 ... >>

USB 3.2 standard 27.02.2019

Representatives of the USB Implementers Forum (USB-IF) announced the future of the USB standard. It was decided to stop at the USB 3.2 standard and make it the main and only one for the next few years.

This important decision on the popular standard was made because there are several versions of the third generation of USB in the world: 3.0, 3.1 and 3.2 - the last one was approved in 2017. All of them have different specifications, differing from each other in data transfer speed: first, speeds of 5 Gb / s were reached, then up to 10 Gb / s and up to 20 Gb / s in the case of USB 3.2.

However, due to confusion in specifications and an attempt to make backwards compatible connectors, there was a complete mess. Data transfer rates of 5 Gbps were mandated by the USB 3.0 and USB 3.1 Gen 1 specifications. 10 Gbps could be achieved with the USB 3.1 Gen 2 specifications. USB 3.2 specifications, by using two data lanes in a certified cable instead of one, they allowed both exchange at the level of 10 Gb / s and 20 Gb / s. In the case of only one line, depending on the version of the host controller, USB 3.2 can also work at 5 Gb / s.

As a result, the USB-IF organization was fed up with the confusion over the specifications of the third generation USB interface, and they decided to make USB 3.2 the main standard for this connector for the coming years. Thus, from the middle of 2019, all manufacturers will start releasing their devices with a USB 3.2 port, and there is no talk of USB 4.0 yet.

USB 3.2 will have three speed options: SuperSpeed USB, SuperSpeed USB 10Gbps, and SuperSpeed USB 20Gbps. For ordinary people, this is understandable and clearly speaks of the capabilities of USB ports.
