Comments on the article

As the gray stain for wood it is good to use water-soluble, durable and light aniline paint nigrosine.

A solution of 7 parts of nigrosine in 1000 parts of water turns the wood into a beautiful silver-gray color, which is so durable that even after two years it does not change at all.

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 ... >>

Apples won't turn brown 29.01.2017

The U.S. Food and Drug Administration (USFDA) has authorized the sale of genetically modified apples developed by the Canadian company Okanagan Specialty Fruits.

Transgenic Arctic apples have one interesting feature - they do not darken from cuts or bites. Contrary to prejudices, this does not mean at all that they do not contain iron! Apples contain antioxidants, thanks to which these fruits are considered so useful for our body - for example, polyphenols. Apples also contain the enzyme polyphenol oxidase, which is needed to oxidize polyphenols.

In order for these two substances to begin to interact, oxygen is needed from the air. If you cut or bite off an apple, a chemical oxidation reaction of polyphenols begins and the flesh becomes covered with a brown coating. In fact, it protects the fruit from parasites and microorganisms for which such an apple becomes unattractive. Genetically modified Canadian apples of the "Arctic" variety are spared this feature.

Thanks to the efforts of Canadian scientists, transgenic apples do not oxidize antioxidants and do not darken for up to three weeks. Canadians have already grown 85 thousand fruit trees, and by 2018 their number is planned to increase to 500 thousand. Now the fruits are finally on sale in several supermarkets across the US, and the creators promise that Artic will be cheaper than the usual varieties of apples.
