What animals can't recognize familiar food away from their trees?

The koala has a large head, but the ratio of brain to body weight is one of the lowest among mammals, and the surface of the brain is almost smooth. Because of this, koalas are not capable of complex mental activity. For example, if the eucalyptus leaves that they eat all the time are plucked and placed on a surface away from the tree, the koala will not eat them.

Why do animals love salt?

The passion for salty foods in both humans and animals is one of the most interesting mysteries of wildlife. We know that for thousands of years man has valued salt and used it for cooking. In ancient Mexico, salt was considered such an important product that every year a beautiful girl was sacrificed to the salt god.

Today, examples are known when a prisoner in prison, who was brought food without a grain of salt in it, began to go crazy from its lack. The fluid circulating in our body is a salt solution. Since our body releases a certain amount of moisture from itself in various ways, with which the body loses salt, these losses must be compensated.

Salt reserves on Earth are distributed in such a way that a huge amount of it is contained in ocean water, while on land its reserves are relatively small.

Plants contain a small amount of salt, and it is washed out of the soil by rains into rivers and further into the seas and oceans. Animals - inhabitants of the land, however, once descended from marine inhabitants. The composition of their body juices is the same as that of their ancestors, and similar to sea water!

And since neither the plants nor the soil can provide them with enough salt, they pounce on any salty food with such greed. Only carnivores, that is, those that eat other animals, do not have a special craving for salty food: they get salt along with the meat of their victims. In contrast, most herbivores are very fond of salt.

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, ... >>

Skin profilometry 11.02.2000

Employees of the Laboratory of Friction and System Dynamics from Lyon (France) have created a laser device that allows cosmetologists to accurately track the effect of creams, masks, lotions and other products that eliminate wrinkles.

The thinnest laser beam glides over the surface of the skin, its reflection is captured by four photodiodes. The result is a three-dimensional map of the skin area with relief lines every 10 micrometers.

By repeating such measurements, one can evaluate the effectiveness of a cosmetic product not by eye, as has been done so far, but in exact numbers.
