Why is white drink chilled, and red - at room temperature?

Red wine contains many natural acids and tannins that white wine does not. They pass into the wine from the skin of grapes, giving the wine color. If red wine is cooled, these substances will not be felt on the palate, and the “bouquet” of the wine will become much poorer.

How did the atheist's request to kill him with magic end?

On March 3, 2008, the atheist Sanal Edamaruku challenged a well-known Indian sorcerer on a popular Indian TV show, asking him to demonstrate his power on him - to kill with magic. For several hours the sorcerer unsuccessfully performed ritual actions, and, having not achieved success, he concluded that the atheist was "protected by a very strong deity."

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 ... >>

How to name the medicine 10.08.2006

Canadian programmer Greg Kondrak is passionate about languages. He speaks Polish, English and Spanish, and has good knowledge of French, German and Esperanto.

While still a graduate student at the University of Toronto, Kondrak wrote a computer program that heard similarities between words in different languages. The degree of similarity is expressed by a figure - the coefficient of similarity, which makes it possible to judge the possible relationship between languages.

For example, the computer claims that the Russian word "brother" is related to the German "bruder" and the English "brother", but is very different from the Spanish "ermano", although all four words mean the same thing. This means that Russian is close to German and English, but far from Spanish.

Philologists, having familiarized themselves with the program, found that it did not open anything new for them. However, the brainchild of Kondrak found a job in an unexpected area - the search for names for new medicines. There are now so many drugs that it is not easy to find a new name that is not similar to some already known one, and this similarity can lead to dire consequences. For example, erythromycin, erythropoietin and erythrocin or cystamine, cysteine and cystenal are used in completely different cases.

The US Food and Drug Administration has a whole team of specialists who check how the proposed new names differ from the existing ones. A computer with a new program will greatly facilitate their work.
