Sleeping before bed improves memory

06.02.2019

Children are usually rocked before bed so that they fall asleep faster. But, as experiments show, lulling helps to sleep not only for children, but also for adults. Researchers from the Universities of Geneva and Lausanne invited 18 volunteers to spend three nights in the laboratory. On the first night, they simply got used to the new environment, and on the other two, some participants in the experiment began to rock on a special bed before going to bed, while others continued to sleep as usual.

Those who were rocked fell asleep faster, slept longer, their sleep was deeper. And their memory also improved: in the morning, those who were rocked, remembered better the pairs of words that they were asked to learn before going to bed.

Brain activity during sleep was recorded using electroencephalography. It turned out that rhythmic motion sickness helps to synchronize neural activity in thalamocortical neural networks, which are actively involved in the regulation of sleep and the transformation of memory from short-term to long-term.

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 ... >>

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, ... >>

Balloons with GLONASS 01.07.2013

From 9 to 15 June, the 18th International Meeting of Balloonists was held in Velikiye Luki. For the first time in the history of the competition, balloons are equipped with the GLONASS system, and it was possible to watch the flights of the crews online.

This year 50 teams from Moscow, St. Petersburg, Tula, Nizhny Novgorod, Omsk, Perm region, Latvia, Lithuania, Ukraine and Belarus took part in the competition. Several cups were raffled off at the competition, including: the Cup of Russia in aeronautics, the Friendship Cup among all pilots of the competition, the Cup of Velikiye Luki, the Cup of Princess Olga, which will be awarded to the best female pilot.

Equipping the balloons with the GLONASS monitoring system is a technical innovation this year. FORT navigation equipment was installed on 15 aircraft. With the help of terminals, the speed of the balloon, its height and location are measured.

Vladimir Makarenko, Development Director of Fort-Telecom, the manufacturer of the FORT GLONASS monitoring system, notes that, as a rule, navigation terminals are used to monitor the operation and movement of vehicles, and it is connected to the vehicle's electrical circuits. “In the case of monitoring balloons at the International Meeting of Balloonists, we used terminals with a built-in rechargeable battery that holds a charge for up to 12 hours. This charge is enough for one flight, after which the battery is recharged,” Makarenko explained.

He said that in any monitoring system, data about the controlled object is transmitted to the server through stationary GSM cell towers, and there were fears that the horizontally directed antennas of the towers would not be able to provide proper signal reception at a height. Therefore, it was originally planned to install FORT navigation terminals on the balloons, supporting data transmission both via GSM networks and Wi-Fi technology. It was planned to deploy mobile "points" of data transmission along the routes of the balloons. But before the start of the competition, tests were carried out, during which it turned out that for flights at an altitude of up to 500 meters, ordinary FORT navigation terminals transmitting data via GSM networks are quite enough.
