What insects tend to compensate for love failures with alcohol?

American biologists, studying the mating behavior of male fruit flies, offered them a choice of two feeders - one contained ordinary sugar syrup, the other had the same, but diluted with alcohol. Those males whose courtship was rejected by the females drank from the trough with alcohol much more often. The reason for this was a reduced concentration in their body of a protein called neuropeptide F, which acts on the pleasure center of the insect - not receiving it due to lack of mating, the flies tried to fill the gap with alcohol consumption.

Random interesting fact from the Great Encyclopedia:

Does your hair turn gray from fear?

Yes, they sit. But it is rather unclear how and why this happens. We still cannot even fully explain why older people turn gray! But let's think about it anyway.

Hair is a skin formation. Their roots are in the skin, letting out, like an onion, "sprouts" upwards. As soon as the hair cells appear above the skin as they grow, they change and become horny. From the outer end of the cells are constantly multiplying, on top of some others appear.

Among the cells of the hair roots there are those that contain pigment. They also multiply and appear higher and higher. As the hair shaft grows, they eventually die, and the pigment granules are destroyed.

The horny substance of the hair is yellow, while the pigment granules are from red to black-brown. This explains the various shades of hair that we know, from white to black.

One of the explanations for the appearance of gray hair is that with age, due to illness, anxiety, a strong fright, the pigment becomes less and the hair color turns gray. Another explanation is that air bubbles begin to replace pigment granules due to nervous stress and negative emotions. But the mechanism of this phenomenon is still unknown to us.

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, ... >>

sensitive road 02.03.2000

If carbon fibers are mixed into concrete, such a road surface will change its electrical conductivity under the influence of the weight of cars passing on it.

Deborah Chang from the University of Buffalo (USA), who discovered this effect, suggests using it to make roads sensitive to the movement of cars and even bicycles.

It will be possible to measure the weight of heavy vehicles on the move (and charge them a fare corresponding to the weight), determine the location and speed of individual vehicles, use their signals to switch traffic lights.
