Cotton against cancer

20.08.2007

Chinese doctors, after analyzing a data bank on the health of tens of thousands of workers in Shanghai cotton gins and weaving factories, came to the conclusion that cotton dust in the air protects against lung cancer.

Women who are exposed to high concentrations of cotton dust in the workplace are 40% less likely to develop cancer than those who do not breathe such dust. On average, out of 100 textile workers, lung cancer is found in 7 to 8 people, and among the entire population of Shanghai - in 19. The reasons for this phenomenon are unclear.

However, Canadian specialist George Astrakianakis, who got acquainted with the results of the study, believes that certain substances contained in bacteria that develop on cotton fiber can play a protective role.

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, ... >>

Return of Odysseus 02.04.2009

In Homer's "Odyssey" various astronomical events are repeatedly mentioned.

So, in sailing from Troy to Ithaca, Odysseus focuses on the constellations Pleiades and Bootes (and they are visible in the sky at the same time only in March and September). On the morning of arrival at Ithaca, Venus is visible before sunrise. The phase of the moon is approaching the new moon. Homer also writes that the god Hermes flew to the western island of Ogygia and immediately flew back to the east.

This is associated with the movement of Mercury (the Roman name of Hermes) through the sky. The planet changes its apparent direction of motion from west to east every 116 days. And most importantly, in Canto XX, the soothsayer Theoclymenes, predicting the death of Penelope's suitors, speaks of a "terrible shadow" that "rises on the heavenly sun" and "under it the whole earth is covered with darkness" - a clear description of a solar eclipse.

Comparing all these indications, employees of the Rockefeller University (USA) Marcello Magnasco and Constantino Baykuzis calculated the day when Odysseus returned from a long voyage. Dates of past solar eclipses are known with great accuracy.

The astronomical phenomena indicated by Homer during the eclipse in the region of the Ionian Islands coincide only once in 2000 years, and it turns out that the eclipse mentioned in the poem fell on April 16, 1178 BC.
