When were wheeled bags invented?

The first patent for a bag with wheels was issued in the US only in 1972. The idea to connect them instead of using carts came from Bernard Sadow, vice president of a bag manufacturing company in Massachusetts. In his version, the product was supplied with four wheels, and it was necessary to pull it by a leather loop. And only in 1987, the pilot Robert Plath invented and patented the bag we are used to with a retractable handle.

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. ... >>

Ultrasound Influences Decision Making 05.11.2019

A new experiment by scientists at the University of Plymouth in the UK has shown for the first time that the frontal region of the brain, known as the anterior cingulate gyrus, can regulate counterfeit thinking.

Counterfeit thinking is a type of decision making that involves considering options that are not currently available but may be available in the future. An example of counterfeit thinking is a person working indoors on a sunny day and at the same time saying to himself: "I could be outside enjoying the sun."

Scientists altered counterfeit thinking in monkeys by targeting neurons in their anterior cingulate gyrus with non-invasive, low-intensity ultrasound.

As part of the experiment, experts observed macaques who chose a delicacy from a number of options. The monkeys were quick to make a choice, but when it came to making it, it was out of their reach. However, they kept this choice in mind when it became available the next time.

Using fMRI scans of the monkeys' brains, the researchers found that activity in the cingulate cortex predicted whether the monkeys' perceptions of future choices would be translated into actual behavioral changes in the animals. And stimulating a region of the brain with non-invasive, low-intensity focused ultrasound disrupted the monkeys' counterfeit thinking, changing their choices.

The scientists conclude that brain stimulation with non-invasive, low-intensity focused ultrasound could improve the lives of millions of mentally ill patients. Some brain stimulation techniques are already helping people with Parkinson's disease and depression.
