Diabetes is increasingly leading to blindness

09.09.2016

Scientists compared the statistics and came to the conclusion that diabetes is increasingly leading to blindness in people. Such consequences manifested themselves in every 39th person in the world. At the same time, statistics indicate that the number of sick and injured people's eyesight is increasing. The reason is that the onset of the disease has no symptoms. That is why people turn to doctors only when it is almost impossible to restore vision. Scientists are sounding the alarm. They believe that the state should take control of this problem.

Blindness begins to occur as a result of retinopathy, which is provoked by diabetes mellitus. It occurs gradually, eventually developing into complete blindness. It all starts with the destruction of the small vessels of the eye. This leads to hemorrhages, which ultimately reduce vision.

In addition, new blood vessels are formed at the same time. But they are not what they should be. Abnormal vessels with scars from hemorrhages are obtained. This, in turn, further reduces vision. In order not to lose the ability to see, scientists recommend that diabetics visit a doctor regularly.

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, ... >>

Bioenergy from grape shoots 20.01.2024

A research team from the University of Jaén in Spain and the University of Sao Paulo in Brazil has confirmed the possibility of extracting hydrogen from grapevine shoots using an environmentally friendly process that does not rely on fossil fuels. This work brings new meaning to waste from the wine industry, providing a solution to create clean energy.

The researchers' work not only confirms the effectiveness of the process of producing hydrogen from grape shoots, but also opens up new prospects for creating clean and sustainable energy using biomass from the wine industry.

Grape shoots, which make up a significant portion of winemaking waste, were previously used mainly for compost or as a source of fuel. However, scientists propose an alternative use for these wastes based on their biological treatment with enzymes.

The biological enzyme pretreatment process appeared to be the best option for industrial hydrogen production. Unlike chemical and physical methods, this process is not only more environmentally friendly, since it does not involve waste processing and does not emit toxic compounds, but also increases hydrogen production by almost 250%.

The researchers call for further techno-economic and environmental assessments of the process. They intend to analyze the environmental impact of large-scale use of fermentation plants and assess the economic feasibility of creating a biorefinery based on grape branches.
