Where did the classic men's suit come from?

Around 1860, a fashion appeared - to sew a man's frock coat, waistcoat and trousers from the same material. This "walking suit" was first worn only while riding, so a slit was made on the back of the jackets - a slot. It has survived to this day, although now it has lost its meaning.

What reptiles can run on the surface of the water?

Basilisk lizards are able to run on the surface of the water, holding on due to the rapid rearrangement of their hind legs. The film of water does not have time to break through the weight of the body due to the horizontal position of the leg and the contact time, which does not exceed 0,1 seconds.

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 Benefits of Vibrations 20.03.2017

Scientists from Augusta University, USA conducted an analysis of the results of using a less common type of body exercise - "vibration of the whole body" (BVT). It turned out that in mice, bones and muscles react in much the same way as regular exercise. This observation can be useful to quite a few who cannot go to the gym.

Such vibration looks like this: a person sits, stands or lies on a machine with a vibrating platform, and when it vibrates, it transfers energy to the body, so that the muscles contract and relax several times per second.

The researchers took two groups of male mice, five weeks old. They put normal mice in one group, and genetically modified mice in the other so as not to respond to the hormone leptin (which contributes to the feeling of fullness after eating). Mice from both groups were subjected to different exercises.

After a week had passed, as the mice became accustomed to the equipment, both groups began a 12-week exercise program. Mice in the IWT group "worked out" for 20 minutes a day, vibrating at a frequency of 32 Hz, with an acceleration of 0.5g. In another group, the mice walked on a slightly incline treadmill for 45 minutes a day. Finally, mice in the control group were not exercised at all. all mice were weighed monthly.

Mice genetically destined to be obese received similar metabolic benefits from the treadmill and IWT, and gained less weight than mice not exercising at all, although they remained heavier than normal and exercised mice. In addition, both types of exercise increased muscle mass and insulin sensitivity in genetically engineered mice.

All this together leads to the conclusion that therapy with IWT can be very useful for people with morbid obesity. And in general, many find it difficult, for various reasons, to exercise regularly, which only contributes to the spread of obesity and diabetes, which, in turn, weaken the bones.
