The rain can dry

10.11.2001

Until now, in order to prevent rain, the clouds were seeded with silver iodide or dry ice. This made it possible to cause the condensation of the smallest drops in them into larger ones, unable to stay in the air and falling out on the way to the object that needs to be protected from precipitation.

Now there is another way: the clouds can be dried. The American firm Dyn-O-Mat has developed a polymer powder, each grain of which absorbs 2000 times more water than it weighs.

Having scattered 4 tons of this powder from an airplane over a thundercloud measuring 4000 by 1600 meters, the company's specialists made it disappear right before our eyes. Soaked with water, polymer particles fall to the ground and gradually decompose without causing harm to people and the environment.

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, ... >>

DNA and French cooking 03.05.2004

Real delicacy truffles (and in France truffles from Perigord are considered the best) now cost up to 1000 euros per kilogram.

The rarest white Italian truffles from Piedmont - even up to five thousand. But in recent years, they have been competing on the European market with much cheaper low-quality Chinese truffles, outwardly indistinguishable from real ones even for a specialist. The difference is felt only in the cooked dish.

Chinese mushrooms lend themselves to mass cultivation and cost up to 20 euros per kilogram. Often they are sold under the guise of French. In addition, Chinese truffles pose a danger of ecological aggression: they grow much faster than European ones, and if their spores get into the forest soil, the Chinese species can displace the European one.

The Institute for Agricultural Research in Clermont-Ferrand (France) has developed a simple mushroom DNA test method that can reliably distinguish cheap Chinese from noble truffles. The analysis is recommended for wholesalers when purchasing large quantities of mushrooms.
