Random interesting fact from the Great Encyclopedia:

How do lemmings die?

No, they don't commit mass suicide - if that's what you're thinking.

Apparently, we owe the idea of suicide to the scientific work of naturalists of the XNUMXth century, who observed (but never understood) the four-year "boom-bust" population cycle of the Norwegian lemming (Lemmus lemmus).

Lemmings have a phenomenal ability to reproduce. One female can give up to eighty offspring annually. Sudden bursts of lemmings even led the Scandinavians to believe that they spontaneously breed when the weather is favorable. What actually happens is that mild winters lead to overpopulation, which in turn leads to overgrazing. In search of food, lemmings go to explore uncharted territories and go until they stumble upon a natural obstacle like an abyss, lake or sea. And the rears are pushing. There is panic and confusion. There are also accidents. But it's not suicide.

There is another, side myth: that the whole idea of mass suicide was invented in the Disney film The White Wasteland (1958). The truth here is that the film was an absolute fake. It was filmed in the Canadian province of Alberta, surrounded by land and never seen lemmings, the animal actors had to be transported as far as Manitoba, several hundred miles away. The "mass migration" footage was taken with a dozen lemmings on a snow-strewn turntable. And the famous final scene (where the lemmings throw themselves into the sea under the tragic voice-over of Winston Hibbler, filled with hopelessness: “The last chance to turn, but you can’t stop them one more step - and their bodies break into a bottomless abyss”) was filmed without any special ideas at all: the creators films simply threw the poor fellows into the river.

However, Disney is only guilty of trying to recreate a story already ingrained in our brains. Here is how it is described in the most influential children's textbook of the early 1908th century, Arthur Mee's Children's Encyclopedia, published in XNUMX: water and causing typhus ... forward and forward, to the sea, and further - into the water, to their own death ... It's terrible and sad, but if it weren't for such a sad outcome, lemmings would have swallowed up all of Europe long ago.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The oceans are rapidly cooling 06.01.2019

After some study of the oceans, scientists from Woods Hole Oceanic and Harvard universities came to the conclusion that at the moment the weather on the planet is the same as in 1870.

The Pacific Ocean, the waters of which were studied, is characterized by a weak current, so the upper layers of water there sink down only after 200 years. Therefore, the temperature of the water at a depth of about two kilometers allows us to find out how cold it was two centuries ago - at the time when the Little Ice Age ended.

At the moment, the World Ocean is cooling down again: the temperature of the upper layer in the Pacific Ocean has decreased by 0,08 ° C. This process began at the end of the last century. When it will stop, it is impossible to say.
