Ion microscope

07.02.2021

Scientists from the University of Stuttgart (Germany) have developed a powerful ion microscope to study quantum gases.

Unlike most microscopes designed to study quantum gases, this device is not limited to the reconstruction of two-dimensional systems and allows you to study with spatial and temporal resolution completely different systems, such as samples in the ground state, Rydberg ensembles, or cold ions immersed in quantum gases.

The researchers plan to use the new tool to expand research on cold ion-atom hybrid flows, and intend to prove the collision energies in these flows in ultracold mode.

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, ... >>

Walking speed measurement without wearable devices 08.05.2017

The Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Lab has found a way to measure walking speeds with 95 to 99% accuracy without the need for additional wearable devices. WiGait technology uses wireless signals sent by devices like routers. Such devices can be located in different parts of the house.

The WiGait system is designed for home use: you can install it in any convenient place so that it does not interfere at all. It constantly measures walking speed and stride length, and the user does not need to wear any device and, accordingly, worry about charging.

The ability to track walking speed is of great benefit to clinical research. There is growing evidence that this indicator helps predict health problems. The ability to notice changes in stride length also helps identify certain medical conditions, such as Parkinson's disease.

WiGait stands out from other solutions in this area because it does not require any wearable devices and does not involve cameras, which can also be useful, but often have a number of privacy problems. The patient is much more comfortable when his steps are monitored by a simple sensor, and not by the eye of the camera, which, even at a subconscious level, can be perceived as a surveillance device.

The development has great therapeutic potential in long-term care and geriatric medicine. Interest in a field that specializes in diseases of the senile age is growing as the average life expectancy increases, but at the same time, the demographic aging of the population is taking place.
