People with myopia sleep worse than people with normal vision

02.06.2021

Researchers from Flinders University (Adelaide, Australia) found that people with myopia (the medical term for nearsightedness) have worse sleep quality than people with normal vision due to delayed circadian rhythms and relatively low production of melatonin, a hormone responsible for regulating sleep. in nighttime.

The team analyzed circadian rhythms - 24-hour cycles that are part of the body's internal clock - and melatonin production in university students in their 20s, some of whom had myopia and others with normal vision. An analysis of the results showed that participants with myopia had significantly slowed circadian rhythms and low levels of melatonin in saliva and urine compared to participants with normal vision. At the same time, the question of what is the effect and what is the cause remains open. It is possible that it is the disruption of circadian sleep rhythms that causes a decrease in melatonin levels, and this, in turn, can trigger the mechanism of progressive myopia.

Circadian rhythm and sleep disturbances due to the advent of artificial light and the use of light-emitting electronic devices for reading and entertainment have become a recognized health problem in many parts of the world. However, their effects on eye health are still poorly understood.

The team now plans to follow up by further evaluating circadian timing and the consequences of disruption in young children, the main target group for myopia prevention. Such research will provide new insights into the biological and environmental factors that underlie myopia and help in its early diagnosis and treatment in children.

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, ... >>

Milk in A4 format 04.08.2023

German food manufacturer Veganz has unveiled a unique development, Mililk technology, which includes 2D printed sheets that turn into oat milk.

The product is a square sheet of sweet shade, A4 size, which makes it convenient to send them through mailboxes. Each leaf is capable of producing 500 ml of delicious oat milk, and the €17,99 package includes enough sheets to make 10 liters of milk.

It is enough for the consumer to tear off the required number of sheets and mix them with water for one and a half minutes to get fresh oat milk.

Mililk leaves include oat powder, some water, coconut oil, chickpea isolate, vanillin, and gellan gum.

The manufacturer emphasizes that the production of milk in sheet format has a low ecological impact on the environment, as it avoids a large amount of waste. In addition, the consumer can prepare exactly as much milk as he needs at a certain point in time.

This format of oat milk is highly convenient for transportation, since water makes up 90% of the product. The Mililk packaging only includes a recyclable envelope, unlike the many Tetra Pak (common plant-based milk packaging) or cartons that are simply thrown away.
