What rodents squeak at the moon like wolves?

In Mexico and the southern United States, the grasshopper hamster lives - a nocturnal predator that is very different in behavior from most rodents. He preys on grasshoppers, scorpions and snakes, to the poison of which he has developed immunity, and even other mice. To mark its territory, the hamster periodically stands on its hind legs, throws its head back and makes a long squeak, which is very similar to a wolf howling at the moon.

Why don't we fall off the bike?

Pedaling a bicycle, we never think about what forces keep us in a level position, why we do not fall. Two things keep us on the bike. The first is the rotating force, which is also called gyroscopic.

A gyroscope is a top mounted in such a way that its center of gravity remains in the same place, no matter how the gyroscope rotates. When the gyroscope wheel begins to spin, it maintains its position in space until external forces act on it. The same thing happens to a bicycle wheel when it starts spinning. The wheels remain balanced until they encounter forces that can change their direction.

The second force that helps us stay on the bike is the force of inertia. An example of this force can be observed when you are thrown to the side in a car if it turns sharply. If you start to fall off your bike, you turn the front wheel in the direction of the fall. The force of inertia aligns your position. In order not to fall, you turn the steering wheel slightly to the right, then to the left. In other words, you turn the steering wheel without thinking about it, in such a way that the force of inertia constantly keeps you in balance.

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, ... >>
