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 benefits of sex for athletes 20.10.2016

Laura Stefani from the University of Florence (Italy) and her colleagues analyzed and summarized data from scientific publications on the impact of the sexual life of athletes on their performance. They came to the conclusion that the prejudice that sex before the start is harmful is nothing more than a ridiculous myth.

The notion that sexual intimacy before a competition negatively affects athletes has existed since ancient times. Back in the XNUMXst century AD. the ancient Roman physician and philosopher Areteus of Cappadocia wrote that male power can weaken, transforming into a seed. Even earlier, the Greek philosopher Plato condemned the Olympians who practiced intimacy on the eve of the competition.

Nowadays, such an opinion exists, for example, among football coaches, and fans of the film about Rocky remember his mentor's warnings that "women make legs weak."

Scientists have analyzed more than 500 different scientific publications relating to the relationship of sex with physical activity. Surprisingly, there are practically no works dealing with this problem in detail. Of the nine studies that have been published over the past 60 years, researchers have found that none address this question systematically.

The researchers concluded that sex the night before a competition may even have a positive effect on athletic performance.

"In general, there is an overall positive effect of sex the night before a competition on an athlete's performance, especially from a psychological point of view. Sex has a relaxing effect that can help reduce stress, increase endurance (important for marathon runners) or concentration (when shooting)" , the authors write.

However, the researchers caution that the available material is somewhat ad hoc and there is still no reliable data on the correlation between sex and fitness.

Scientists talk about the positive impact of sex at least ten hours before the start, provided that the athlete does not smoke or drink alcohol.
