What claimed more lives during the First World War than the hostilities themselves?

In the First World War, 14 million people died, and during the same period, at least 20 million died from the Spanish flu epidemic. The exact number of victims of the Spaniard is unknown - according to modern estimates, she claimed the lives of 50 to 100 million.

How does a snake inject its venom?

In poisonous snakes, one of the salivary glands produces a substance that is dangerous to the victim. This substance is snake venom. The venom of some snakes is so dangerous that it can kill an elephant. In others, this substance is not so toxic. They can only kill a small lizard. Only two hundred venomous snakes out of 412 known species are considered dangerous to humans. Two of them are African snakes: rattlesnake and flying. They have fangs in their mouths.

Fangs are two or three teeth, greatly enlarged and having a groove on one side. Just above the fangs there is an opening leading to a poison-producing gland. When a venomous snake bites, the venom enters the trough and flows through it into the wound made by the fang. The cobra has fangs at the front of its mouth, one on each side. In most cobras, the canine groove is covered, forming a tube. The venom gland is surrounded by muscles. When the snake bites, the muscles press on the gland. This entails the flow of poison into the gutter, and then through the fang into the victim.

A cobra can inject venom from a fang, just like a liquid from a syringe. It's a spitting cobra. She aims directly at the victim's eyes. Its jet reaches almost 2,5 meters and almost always causes blindness. Poisonous snakes have a very perfect venom delivery system. Their fangs are very long, but can fit into the mouth so that the mouth can close. When the mouth opens to bite, the jaw moves forward, carrying the fangs at the correct angle to the throat.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>
