Males of what animals actively help females to eat themselves during mating?

In many spider species, the female may eat the male after, during, or instead of mating. In the vast majority of cases, he tries to avoid such a fate, but in the species of Australian widows, males actively help the act of sexual cannibalism. Having inserted the pedipalp into the female's genital opening, the male performs a somersault and places his stomach opposite her mouth. Self-sacrifice serves two purposes: eating increases mating time, which leads to the fertilization of more eggs, and a well-fed female is more likely to reject other suitors. According to studies, less than 20% of male Australian widows, in principle, find a partner for themselves during their lives, so leaving their genes to their descendants, albeit with a foregone conclusion, is a great success for them.

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 ... >>

Limited information motivates children to learn 04.07.2021

Researchers at Rutgers University found that limited information motivates young children to learn. According to the study, preschool children are sensitive to the difference between how much they know and how much they still have to learn.

Preschool children tend to choose to gather more information about something if it interests them. This ability creates the perfect combination of insecurity and curiosity in children and motivates them to learn more.

The study focused on how the level of knowledge of children affects what information they are interested in. The data obtained indicate that children are attracted not only by the novelty of information. Children are naturally curious, scientists say, but the tricky question is how to harness that natural curiosity.

In a series of experiments, the authors developed personal and online storybooks to measure how many 3- to 5-year-old preschoolers knew about different "knowledge areas". The experiment also assessed their ability to understand a specific topic, such as contagion, and asked how the children's current level of knowledge predicted their interest in learning about the subject, including whether someone would get sick after playing with a sneezing friend.

Intuitively, curiosity seems to belong to those who know the most, like scientists, and those who know the least, like babies. But what the authors of the study found is rather surprising: it was children of this age who showed the greatest interest in studying the topic of infection, compared with children who knew too little or too much. The results of the study will help parents and educators better support children as they actively explore and experience the world.
