mosquito tomato

16.09.2002

The American chemist Michael Rowe, while testing new compounds that repel insects, suddenly noticed that one of them, in terms of the structure of the molecule, is very similar to some kind of oily organic substance that is part of tomatoes.

He synthesized this substance, soaked a piece of gauze with it and threw it into a jar of cockroaches. The insects immediately fled. It turned out that the "tomato" compound also repels mosquitoes. Compared to the well-known DEET repellent, it is no less active, but lasts longer on the skin and does not cause allergies.

The chemist does not disclose the true name of the new repellent (a patent has not yet been issued), but reports that this substance has long been known, is used in cosmetics, and its harmlessness has been fully proven. Therefore, there is hope that the new repellent will be on sale by the next mosquito season.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Bosch Smart Refrigerator Powered by Blockchain 15.04.2019

Sometimes advanced technologies appear in the most unexpected solutions. This is what happened with blockchain technology. It was integrated into the refrigerator. Of course, in a smart refrigerator.

For example, Bosch has collaborated with leading Austrian energy supplier Wien Energie to create an advanced refrigerator that uses blockchain technology to record where the energy that feeds it comes from. Wien Energie also notes that the owners of such a refrigerator will be able to control the device through a mobile application, view its energy consumption and select an energy source.

The main idea is to teach owners to use cleaner energy, and blockchain technology will allow them to easily choose (and change) electricity suppliers. Considering that detailed information about energy generation, including the sources used for this, will be recorded in the distributed ledger, "each kilowatt will receive an exact" biography "and it will be clear due to what and how it was created," Wien Energie says . In addition, thanks to a smart contract, the refrigerator will automatically be able to send micropayments for each kilowatt-hour of electricity consumed. Bosch and Wien Energie claim that this is a kind of proof of the source of energy generation.

There are other "smart" features in the new Bosch conceptual refrigerator. For example, it can notify if a door is left open for too long.
