faster than light

05.11.2011

Physicists from the European Organization for Nuclear Research report that neutrinos generated in an accelerator near Geneva traveled 732 kilometers through the earth to a detector of these particles installed in an underground tunnel in Italy, 60 nanoseconds faster than Einstein's theory suggests.

As you know, she claims that no material body can move faster than light (299 meters per second), and according to measurements taken on 792 thousand neutrino events, the speed of these particles was 458 meters per second.

The difference is small, but if it is real, that they will still check, double-check and interpret, it will be necessary to question the special theory of relativity and the far-reaching not only physical, but also philosophical conclusions related to it.

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 ... >>

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, ... >>

An effective way to control mosquitoes 15.06.2020

An aerosol made by combining a type of volcanic glass with water has shown an effective method to control malaria-carrying mosquitoes, according to a new study. The results obtained may be useful for reducing the populations of these insects in Africa.

Malaria, an infectious disease transmitted by mosquitoes. Every year, the disease claims the lives of about 400 people in Africa.

There are many remedies that repel bloodsuckers. But mosquitoes are becoming increasingly resistant to commonly used insecticides such as pyrethroids, so alternative safe chemicals to control them are very important.

Scientists have found that a volcanic mineral, perlite, most commonly used in building materials and as a soil additive in gardens, may also help control malaria mosquitoes.

A spray based on it (Imergard WP) was developed for the treatment of interior walls. This aerosol does not contain any additional chemicals, is non-toxic to mammals and will be cost effective. Early results show that mosquitoes are not resistant to perlite aerosol.

The results showed that the mosquito mortality rate in rooms treated with Imergard WP was above 80% within five months of treatment and 78% within six months.

"The statically transferred perlite particles essentially dehydrate the mosquitoes," said Mike Roe, NC State Distinguished Professor of Entomology William Neil Reynolds.

According to scientists, mosquitoes die within a few hours after contact with the treated surface.
