What birds can sleep on the fly?

Storks during flights can periodically fall asleep without falling to the ground for up to ten minutes. A tired stork moves to the center of the school, closes its eyes and takes a nap, and at this time it is helped to maintain the direction and altitude of the flight by its heightened hearing. The ability to sleep during flight has also been noted by ornithologists in black swifts and sooty terns.

What requirements must a Formula 1 racing car meet?

Formula 1 cars must be equipped with a four-stroke engine with a cylinder capacity of not more than 3000 cm³. There should be no more than 12 such cylinders. Each cylinder should have no more than five valves. The minimum weight of the car with driver is 600 kg. It is prescribed to have a multiple starter, a duplicated brake system (one for all four wheels) and an emergency one for the front wheels, an open driver's seat with a seat belt. Wheels should not have additional lining. However, the rules in this form are constantly changing, this applies to engines and tires.

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, ... >>

Cheap water treatment 20.06.2018

Bob Tilton and Todd Pshibizen, two professors of biomedical engineering and chemical engineering at Carnegie Mellon University, have come up with an interesting way to filter water. It is based on the seeds of the Indian oil tree.

Experts suggested to use the seeds of moringa oilseed. The tree grows well in tropical and subtropical regions and is cultivated for food products and oils. Its seeds have previously purified some types of water, but it has been observed that such water can only remain pure for 24 hours.

The scientists decided to combine the method of sand filtration and the method of isolating protein from moringa seeds. So, by isolating proteins and adsorbing them on the surface of particles of silicon dioxide, the main component of sand, they created "f-sand" ("f-sand"). It is noteworthy that this method of stonecrop is not only cheap, but also universal, since it is suitable for water of any hardness. In addition, the water that has undergone such purification is enriched with useful microelements and "charged".
