Mobile phones have been proven to be safe for health

19.12.2014

Electromagnetic radiation from mobile phones and power lines does not harm human health, scientists from the University of Manchester say.

The scientists sought to test the hypothesis that the electromagnetic fields of mobile devices cause infertility and cancer, as well as contribute to childhood leukemia. These fields are thought to target vital proteins in the human body. Doctors, just in case, are advised to refrain from long conversations on a mobile phone.

Manchester chemists have studied the effects of a weak magnetic field (WMF) on flavoproteins, proteins that play an important role in controlling the nervous system and repairing DNA. It turned out that the radiation does not affect their functioning.

"Flavoproteins transfer electrons from one place to another. Rapidly decaying structures - radical pairs - often appear along this path. Biochemical reactions with their participation are considered the most likely candidate for damage under the influence of electromagnetic radiation. However, the reaction conditions in the human body are such that the biochemical effect of SMP tends to to zero," said study co-author Alex Jones.

Of course, more research will be required, but this work allows us to state with sufficient certainty that power lines, mobile phones and similar devices are safe for humans, said another author of the article Nigel Scrutton (Nigel Scrutton).

Another study conducted by the British Public Health Protection Agency (an independent public organization whose responsibility is to protect the health of the country's citizens from infectious diseases, poisons and radiation) in 2010 also did not find convincing evidence of the harmful effects of mobile phones, base stations and Wi-Fi on human health. Nevertheless, many organizations are calling for further research, because too little time has passed to understand the long-term effects.

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, ... >>

The oceans are losing oxygen 10.12.2019

The International Union for the Conservation of Nature and Natural Resources (IUCN) has published a report according to which the level of oxygen in the world's oceans is declining at an unprecedented rate. Climate change is dangerously exacerbating the situation.

The new study involved 67 scientists from 17 countries. It turned out that since 1950, the level of oxygen in the oceans has decreased by 2%, and the volume of water completely deprived of oxygen has quadrupled since the 1960s.

60 years ago, only 45 regions of the ocean suffered from low oxygen concentrations, in 2011 their number reached 700. According to research, about 50% of oxygen loss in the upper layers of the ocean is caused by global warming.

According to scientists, if the current state of affairs is maintained, an increase in global temperature and an increase in nutrient consumption will lead to the fact that by 2100 the level of oxygen in the ocean will decrease by 3-4%. As a result, giant dead zones will grow, where, under conditions of severe hypoxia, able to survive marine organisms.

The researchers note that deoxygenation threatens large species, including tuna, marlin, swordfish and sharks. Their decline could affect the lives of hundreds of millions of people dependent on fisheries.
