Focus Description:

The magician puts the clock on the table, it stops! Everyone hears the ticking until the clock is placed on the table.

Focus secret:

Any mechanical watch can be used. There is a magnet hidden under the tablecloth. As soon as you put the clock on the table, it will stop. But never do this trick with expensive watches, they may show the wrong time in the future.

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 ... >>

5nm IBM chip 05.06.2017

IBM IT Corporation announced the creation of the first working samples of processors with 5 nanometer transistors. The development was carried out jointly with GlobalFoundries and Samsung Electronics.

The new technology allows up to 30 billion transistors to be placed on a single chip the size of a human fingernail and used in a variety of equipment - from smartphones to spacecraft. The world's first 7nm chips, announced by IBM two years ago, had 20 billion transistors.

A higher density of transistors in a microcircuit increases the speed of the signal passing between them. IBM claims that 5nm solutions are 40% more productive than current 10nm chips, or 75% more energy efficient than them at the same speed.

The presented chip uses a new type of transistors, combined in the so-called silicon nanosheets (silicon nanosheets). They send electrons through four gates, while in the case of FinFET transistors (considered the most advanced at the moment on the mass market), we are talking about three gates. FinFET technology has appeared in 22nm and 14nm semiconductors and is expected to remain in 7nm chips. The semiconductor industry is moving away from FinFET because the technology is not geometrically scalable, said Mukesh Khare, vice president of semiconductor research at IBM Research.

"Going beyond 7nm is an important innovation," comments Hare. "It's an innovation in terms of design and how more transistors are put together. This transistor structure paves the way for a true 5nm process."

At the moment, it is still too early to talk about the commercial release of 5-nm chips (tentative dates - 2020). However, it is already known that for the production of such solutions, IBM will use the technology of photolithography in deep ultraviolet (extreme ultraviolet lithography, EUV).
