Cats prevent asthma in children

17.11.2017

If a cat has lived near the child since birth, the chances that the child will develop asthma become much lower.

After examining data on the health of 377 children at risk for asthma, experts noticed that the TT genotype variation responsible for the development of the disease is deactivated in the presence of cats. At the same time, the presence of a dog at home does not affect the same genes in any way.

According to study lead author Jakob Stockholm, this could be due to cat fungi and bacteria, as well as viruses that pets bring home. Scientists do not yet have an exact answer to the question of how cats affect human genes.

"If we can explain these mechanisms, they can be used to prevent the development of the disease," the scientist said.

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 physical theory of superconductivity is called into question 20.11.2019

Scientists at Stanford University have discovered a phenomenon in superconducting metals that has not yet been explained. It questions the current physical theory of superconductivity and requires quantum computers to describe it.

The researchers studied the transition phase in the Bi-2212 (Bi2Sr2CaCu2O8+x) superconductor using angular resolution photoelectron spectroscopy (ARPES). Intense ultraviolet light knocks electrons out of the sample, and the behavior of electrons in the metal is determined by the energy and speed of the particles.

Superconductivity is caused by electrons which, below a certain critical temperature, form Cooper pairs and can pass through the crystal unhindered. Above this limit, a "strange" phase appears in high-temperature superconductors, in which electrons do not behave as independent particles, as in ordinary metals, but seem to gather in collectives.

In addition to temperature, the degree of doping, that is, the presence of impurities in the metal, affects the phase transition. At a relatively high temperature, the transition between normal and "strange" metal occurs at an impurity content of 19-20 percent. The researchers showed that in this case, the distribution of electron energy changes abruptly. If the temperature is lowered to the superconducting phase, then the jump is smoothed out, and the properties begin to change gradually.

According to a physical principle called a quantum phase transition, this should not happen: a jumplike character should also occur at low temperatures. According to scientists, the phenomenon can be explained by quantum entanglement, and the behavior of particles can only be satisfactorily described using a quantum computer.

Superconductors are materials that conduct electricity with zero resistance. This phenomenon was first discovered at very low temperatures (a few degrees above absolute zero), but then superconductivity was achieved at higher temperatures (92 kelvin).
