Cure for fingerprinting

08.09.2009

Doctors in Singapore have described a curious case of the disappearance of papillary lines on the fingers of a patient who was taking capecitabine, a common cancer chemotherapy drug.

An elderly Chinese man from Singapore was detained at the entrance to the United States, where everyone is fingerprinted at the border. His fingers turned out to be perfectly smooth, did not give any marks, and within four hours the police found out his identity.

Doctors believe that criminal elements are unlikely to take capecitabine into service, so as not to leave prints, the drug has unpleasant side effects and can only be used under medical supervision.

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, ... >>

A well-fed woman becomes more romantic 29.08.2015

Scientists at Drexel University investigated the relationship between food and romantic feelings in women. During the experiment, young girls were assessed the activity of different areas of the brain, and at the same time they were shown pictures of romantic content, and the young ladies themselves went to the experiment either hungry or well fed.

It turned out that the female brain reacts more vividly to romantic images just after eating - the neurons of the reward system responsible for the feeling of pleasure were activated more strongly on a full stomach.

Moreover, curiously, the response of the reinforcement system in this case was the same as for food. Some time ago, the same team of neuroscientists did similar experiments with girls who had been on a diet for a while, with those who were on a diet right now, and with those who had never been into diets.

It turned out that the brains of women who once restricted themselves in nutrition react to delicious food more strongly than those of the other two groups. That is, the pleasure centers worked more strongly on the image of a chocolate cake than on a picture with a carrot, and such a reaction occurred again in the participants who ate the experiment. Then it was concluded that the danger of becoming overweight most of all threatens those who have already quit the diet: even after eating a lot, they are more likely to eat something else "delicious".

But since the reward system responds not only to food, but also to other potentially pleasant stimuli, it was decided to repeat the same thing, only this time with sexually romantic images. Among the participants in the experiment were again those who were fond of diets, and those who lived without diets - and the brain activity in response to romantic signs in the former even more closely resembled the reaction of pleasure centers to food.

On the whole, the general conclusion is this: anticipation of pleasure from "relationships" and from food is processed in many ways by the same neural structures; the increased response to “romance” after eating may indicate that the neurons previously engaged in eating have now been freed up for a new source of pleasure. True, whether this manifests itself in communication with a potential partner will become clear only after additional psychological research.
