Soda spoils the eyes and heart

17.04.2012

Scientists have already found many harmful effects on the human body associated with excessive consumption of carbonated drinks and carbohydrates. However, until now, the effect of soda on the children's body has remained an insufficiently studied issue.

Researchers from the University of Sydney studied the health of about 12 21-year-olds in XNUMX Sydney schools. Attention was paid to the consumption of soda and carbohydrates (in foods such as bread, rice and pasta). This was a continuation of a large-scale project to study the health of modern children. So, last year, a similar study was aimed at checking the health of children who watch too much TV.

In a new study, researchers found that 12-year-olds who drink one or more sodas a day experience narrowing of the arteries at the back of the eye. This anomaly does not affect vision, but is a sign of an increased risk of heart disease and high blood pressure later in life.

Retinal microvessel diameter is a well-known marker of future cardiovascular disease and high blood pressure in adults. Australian scientists have for the first time found a link between this symptom and the consumption of carbohydrates and carbonated drinks in childhood.

Thus, children with a high consumption of soft drinks and carbohydrates have a more unfavorable microvascular pattern compared to those who do not consume a lot of soda or carbohydrates. This means that in the future, children who love "delicious" may experience problems with the cardiovascular system, and these problems will seriously impair the quality of life.

Currently, scientists plan to continue studying the health status of 12-year-old patients. First of all, scientists are interested in whether damage to microvessels will persist in the future, when children turn 17 years old. Apparently, for this part of the children will have to give up excess soda and carbohydrates.

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, ... >>

Bioreactor for soldiers 19.03.2007

American engineers killed two birds with one stone: they learned to hide the traces of an army unit and provided it with a source of electricity.

The supply of fuel, and even more so electricity, without which, for example, an American soldier equipped with electronics cannot take a step, has long been a stumbling block for the modern army. But the source of fuel is located very close to the consumer - these are leftovers, disposable tableware, rags and other garbage, which is formed in considerable quantities at the place where the military contingent is located. Moreover, garbage still needs to be destroyed in order to deprive enemy intelligence of valuable data.

The garbage disposal plant was created by engineers from Purdue University (USA), headed by Professor Michael Ladish, and in case of successful tests, it will become part of the armaments of the American army.

Garbage is first divided into edible and inedible parts. The first is sent to the bioreactor, and the yeast makes alcohol out of it. The second is gasified at a low oxygen content, turning into combustible gases - methane and propane. Then these gases and alcohol are burned, and the generator generates electricity. After that, a pile of ash remains from the mountain of garbage.

"I think this installation will find application not only in the army," says Professor Ladish. "Restaurants, factories, and other enterprises that produce a lot of organic waste may well use it as an additional source of electricity."
