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, ... >>

Contraceptive gel for men 09.07.2012

The application of an experimental contraceptive gel containing a combination of two sex hormones (testosterone and progestin) to the skin reduces the sperm count in the ejaculate of 89% of men to very low values.

In the male body, progestins (synthetic analogues of the female sex hormone progesterone) enhance the contraceptive effect of testosterone. In combination, these two hormones suppress the production of other hormones that regulate sperm formation. Earlier versions of male hormonal contraceptive methods based on this hormonal combination involved the use of progestin-containing pills, implants, or injections.

The new contraceptive drug, developed by researchers at the Los Angeles Institute for Biomedical Research, is a gel applied to the skin that contains the male sex hormone testosterone and a newly developed progestin called nonsider. In addition to the ease of use of the gel, its serious advantage lies in the fact that Nestoron does not have androgenic (inherent in male sex hormones) activity, which can have side effects, such as the appearance of acne or changes in the levels of good and bad cholesterol in the blood.

As part of a primary clinical study, researchers randomly divided 99 healthy men into 3 groups, each of which used one of 6 unidentified gels daily for 3 months. The tested preparations were a gel containing 10 mg of testosterone, or the same gel in combination with a gel containing 8 or 12 mg of nestosterone.

56 men adhered to the study protocol for at least 20 weeks. However, only 23% of participants who used testosterone gel, the concentration of sperm dropped to 1 million per milliliter - a level considered to reduce the likelihood of conception to almost zero. The use of the combined gel provided a similar result in 88-89% of men, depending on the dose of progestin. At the same time, the complete absence of spermatozoa was observed in 78% and 69% of participants who used gels containing 8 and 12 mg of progestin, respectively. For the control group, which used only testosterone gel, this figure was only 23%.

The absence of undesirable side reactions when using the experimental gel indicates the advisability of its further testing in clinical trials.
