Why did Elvis Presley's manager distribute I hate Elvis badges?

American producer Tom Parker recognized the extraordinary talent of Elvis Presley when he was still little known and underage, and in many ways contributed to his promotion and gaining superstar status. To maximize Elvis' income, Parker used many unorthodox methods. For example, he released large-scale badges with the words "I hate Elvis" ("I hate Elvis") to extract money from those who would never buy his records.

Which birds have learned to protect themselves from cuckoos with a password trill?

Australian painted malura birds have developed a defense mechanism against cuckoos. Even above the clutch, they teach future chicks a unique trill, a kind of password, which the chicks then reproduce in order to get food. But other people's chicks, which were thrown by cuckoos, do not have time to learn the trill, as they hatch a few days earlier. However, if one species of cuckoos parasitizing on malyars is completely vulnerable to such protection, then another species has developed response measures in the course of mutual evolution: in most cases, the chicks of this species successfully select the desired trill after several attempts and also get food.

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 ... >>

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.
