Prompter cures stuttering

08.04.2004

Employees of the University of East Carolina (USA) have patented a way to get rid of stuttering.

It has long been known that the speech of a stutterer becomes smooth if he speaks with someone together, in a duet. A device like a hearing aid (there are models that fit in the ear canal or behind the ear) perceives the speech of its owner and, having slightly changed the frequency characteristics, produces the same sound with an adjustable delay of 25-100 milliseconds directly to the eardrum.

The success rate of correcting a speech defect ranges from 50 to 95 percent.

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, ... >>

Carbon dioxide detected near planetary body 09.11.2023

NASA's James Webb Science Space Telescope (JWST) has detected the presence of carbon dioxide in Centaur 39P/Oterma for the first time, providing scientists with a unique opportunity to rethink how the solar system formed.

Centaurs, small planetary bodies orbiting between Jupiter and Neptune, are an interesting class of space objects. Combining features of both comets and asteroids, they have become the focus of astronomers' attention. Although the presence of carbon monoxide has been previously discovered in several centaurs, recent observations from the JWST space telescope give this discovery a new direction.

The centaur chosen for the study, 39P/Oterma, discovered in 1943 by Finnish astronomer Liisi Oterma, provided scientists with an excellent opportunity to study its characteristics. Scientists from Appalachian State University, using JWST's Near Infrared Spectrograph Instrument (NIRSpec), as well as ground-based observations from the Gemini North Observatory and the Lowell Discovery Telescope, were able to confirm the presence of carbon dioxide in the atmosphere of 39P/Oterma.

The extraordinary find is not only that it is the first time carbon dioxide has been detected in a centaur, but also that it has the smallest amount of carbon dioxide found among all centaurs and comets. This discovery challenges previous ideas about the composition of these cosmic bodies and is likely to change the understanding of their role in the early evolution of the Solar System.

Interestingly, although 39P/Oterma is now classified as an inactive comet, its orbit is shifted to the category of centaurs, located between Jupiter and Saturn. This distinguishes it from typical comets and emphasizes the uniqueness of this space object.

The research aims to change the way we think about centaurs and their role in the formation of the solar system, allowing us to better understand the chemical processes and evolution of cosmic objects in our galaxy.
