What animals are able to defend themselves against predators by shooting them with their blood?

Some species of toad-like lizards, in case of extreme danger from a predator, use a unique protective mechanism: they shoot at it with their blood from the corners of their eyes at a distance of up to one and a half meters.

How many stars are there in the universe?

In 2004, Australian astronomers counted all the stars in the visible universe.

To do this, they chose a random square of the sky, measured its brightness, recalculated it from the brightness of the average star to the number of stars, and extended the result to the entire celestial sphere. There are 70 sextillion (7 with 22 zeros) stars in total.

This is 10 times more than the number of grains of sand in all the deserts and on all the beaches of the Earth.

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 ... >>

Environmental and medical harm from crab sticks 05.01.2024

New research from experts from the University of California, USA, has revealed serious consequences of the production of crab and fish sticks for the environment and human health.

The results of the scientific work highlight not only the need for urgent measures to reduce the environmental impact of fish and crab stick production, but also the importance of protecting public health from the negative consequences of this process.

The production of these delicacies is accompanied by air pollution caused by container ships transporting fish to processing sites. Factories that produce fish sticks, crab sticks, and artificial surimi crabmeat use cheap, low-grade fuel, emitting large amounts of sulfur dioxide into the atmosphere.

Environmentalists believe that shipping makes a serious contribution to environmental issues. However, scientists express hope for a reduction in atmospheric emissions after the introduction of new shipping regulations.

However, the impact of this problem is felt not only at the ecosystem level, but also at human health. High concentrations of harmful substances can cause cardiovascular diseases and cancer in the population.
