Focus Description:

If you find a glass pipette with a drawn-out tip, on which an elastic band is put on top, you can do a spectacular trick.

Remove the rubber band, take a glass of very hot water, almost boiling, lower the pipette into it so that it is half filled with water. Then you need to firmly close the upper hole with your finger (in order not to get burned, you can put several layers of some kind of film under your finger) and pull out the pipette. Naturally, water does not pour out of it. If you now quickly turn it over, then a fountain up to a meter high will hit from its tip.

Focus secret:

When you quickly turn the pipette over, hot water begins to flow down the walls and heat the air remaining in the second half. It expands and pushes water out with force.

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 ... >>

New GM Electronic Platform 22.05.2019

General Motors (GM) has unveiled an entirely new electronic platform on which its next generation of vehicles will be built. The platform combines active safety, infotainment and communication features, as well as the development of the company's Super Cruise driver assistance system.

According to the automaker, the development of the automotive industry and vehicles in the next 5-10 years will require a significant increase in the capacity of on-board digital systems in connection with the transition to electric propulsion and the expansion of functionality that helps the driver and protects him and passengers.

GM's new electronics platform will go into production later this year. It should be rolled out to most vehicles in GM's global lineup by 2023. The first model on the new platform will be the 5 Cadillac CT2020 sedan.

In terms of performance, the new platform is five times faster than its predecessor, being able to process up to 4,5 TB of data per hour. The new architecture also enables faster communication within the vehicle itself and to external sources with 100Mbps, 1Gbps and 10Gbps Ethernet connections. The manufacturer also notes enhanced software updates over the air, allowing you to install updates throughout the life of the car.
