Why was the pager invented?

When about half a century ago, the American radio engineer Al Gross invented the pager, he intended this device to urgently call hospital doctors to patients.

But it turned out that the doctors did not want to be called to intensive care at any time. One doctor bluntly said to the inventor: "There is a golf course next to the hospital, do you really think that I would like to be constantly torn off the club?"

In 2001, there were approximately 300 million pagers in operation worldwide.

What famous Russian painting was inspired by bullfighting?

Ilya Repin was inspired to create the painting "Ivan the Terrible and his son Ivan on November 16, 1581" by several events. The first is the assassination of Tsar Alexander II from a bomb explosion, the second is Repin's visit to the concert of Rimsky-Korsakov in the same year, where he was impressed by the music of the Antar symphonic suite and wanted to convey this mood on canvas. And the final stimulus for the artist was a visit to a bullfight in Spain, after which he wrote in his diary: “Misfortunes, living death, murders and blood make up an attracting force ... And I, having probably become infected with this bloodiness, upon arrival home, now started the bloody scene."

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. ... >>

Dangers of Early Antibiotic Use 08.04.2017

Prescribing antibiotic drugs to children can be an extremely dangerous medical practice. A group of scientists from Belgium, Israel and Canada found that early use of antibiotics can lead to a range of serious consequences.

The use of antibiotics negatively affects the composition of the intestinal microflora, as well as the neurochemical activity of brain regions associated with the activity of the immune system. Also, the use of these drugs reduces social activity and anxiety, but increases aggressiveness.

"The early use of antibiotics deals a complex blow to the intestinal microflora - and this, as you know, is an extremely important biological mechanism for the body that controls the immune system. As a result, it suffers to a particularly pronounced degree also because antibiotics, getting into a fragile organism, affect the brain, in particular, those parts of it that regulate immunity," say the authors of the study, employees of Canada's McMaster University.

Scientists confirm their words with the results of experimental studies carried out on laboratory rodents.

Baby mice were injected with penicillin, and then the effects of its use were recorded. The conclusions obtained as a result are also valid for humans, experts say.
