Dream control device

24.04.2018

Researchers at the Massachusetts Institute of Technology Media Lab in the US have developed the Dormio device, which is designed to increase the duration of hypnagogia (microsonics) - an intermediate state between sleep and wakefulness.

According to scientists, a person's stay in a long micro-sleep can improve his creative abilities.

In a state of hypnagogia, a person may experience auditory, visual and tactile hallucinations, but most often the experiences between sleep and wakefulness are not remembered.

Dormio was tested on six volunteers. Initially, it consisted of an Arduino microcontroller mounted on a glove with a pressure sensor and an electroencephalograph (EEG). The subject, before falling asleep, clenched his gloved hand into a fist, pressing on the sensor.

At the same time, the EEG recorded brain activity. When the person fell asleep, the sensors sent a signal to the Jibo robot, which said the phrase "Don't forget to think about the rabbit" or "Don't forget to think about the fork." To prevent deeper sleep, the robot spoke the volunteer's name and the phrase "You are falling asleep."

In the new version of Dormio, the EEG has been replaced with a heart rate sensor, Jibo with a smart phone app, and the pressure sensor with a muscle tension sensor.

In a state of hypnagogia, the subjects answered questions from a robot that recorded their responses. The results of the experiment showed that although not all volunteers remembered the answers, they saw an image of what they were asked to think about. According to scientists, this means that they have a workable microsleep control system at their disposal.

In the second part of the experiment, volunteers were asked to compose a story with a key word they heard in a state of hypnagogia. The story had to be based on what was seen in the micro-dream. The more original the story was, the more points the participant received. The use of Dormio contributed to a more creative approach to the task, and five out of six volunteers scored higher than in the control test.

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, ... >>

Energy-saving solar-powered clothing 20.12.2023

With increasing temperatures on the planet and environmental challenges, people are faced not only with the need to adapt to a changing climate, but also to ensure biological safety in conditions of elevated temperatures. One innovative approach is the creation of solar-powered smart clothing, which scientists say can function as a personal air conditioner (or heater, if necessary).

Innovative technologies in the field of energy-saving clothing that use solar panels for thermoregulation are opening up new prospects for providing comfort in a changing climate. Systems developed by scientists that can regulate body temperature using solar energy provide an effective and convenient way to maintain biological safety in conditions of elevated temperatures. Further development and industrialization of such technologies could make them accessible to a wider range of consumers, reducing dependence on traditional temperature control methods and promoting resilience to climate change.

To ensure the comfort and safety of the human body, it is important to maintain a certain temperature regime. However, with the planet's rising temperatures and the cold regions at the poles, creating clothing that can regulate temperature has become essential. Scientists have developed an innovative thermoregulation system for clothing that combines an organic photovoltaic module and bidirectional electrocaloric devices to provide cooling or heating.

Both components are not only flexible and suitable for use in clothing, but are also powered by sunlight, eliminating the need for external power sources. The developed clothing is designed to expand the thermal comfort zone from 22° - 28°C to 12,5° - 37,6°C.

The efficiency of the device is sufficient to provide 24 hours of operation after 12 hours of charging in sunlight. In addition, it has a simple structure, compact design and can be integrated into existing clothing.

Perhaps the future will bring universal thermoregulation technologies that are not limited to just power supply, and can even support the operation of electronic devices in special conditions.

With the increase in temperature on the planet, clothing with cooling systems is becoming more and more in demand. Over the summer, reports emerged that global companies were providing cooling vests to their outdoor workers. New technologies also include vests with built-in water pumps, made from breathable fabrics, and even built-in fans.
