Who invented the broom?

A broom and a brush are somewhat similar to each other. Of course, the broom is only used for sweeping. Many brushes are also used for this purpose, although they were invented many thousands of years before the broom.

The caveman used brushes made from bundles of animal hair tied to the end of a stick. A kitchen whisk was a bundle of branches, reeds or wood bast tied to a long handle. In colonial times in America, just such brooms were used. And in many countries of today's Europe one can see how streets and floors in houses are swept with such brooms.

The broom known to us today is made of millet stalks. It was first made in America. Either true or not, but there is a legend about its origin. According to legend, a friend of Benjamin Franklin sent one of the clothes brushes made in that country from India. The brush was very similar to a small whisk. Several grains got stuck in the brush, and Franklin planted them in the ground. They took over, and within a few years the crop had spread throughout America.

One day, an old bachelor from Hadley, Massachusetts, needed a new broom. He cut millet stalks, tied them together, and swept the floors in his house. After that, he never used a birch broom again. He began to make these panicles and sold them to his neighbors. When he died in 1843, broom making was already an important industry. About a thousand acres of this plant were grown in Hadley every year. Until now, the main work in the manufacture of panicles is done manually.

What is temperature inversion?

Generally, the air near the surface of the Earth is warmer than at high altitudes above it. The reverse picture is called temperature inversion. It happens when dust, smoke, soot and combustion products rise into the air, forming smog, which is very harmful to human health.

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 risk of the American diet 24.07.2015

It is well known that many Americans do not consume the healthiest foods. For example, it has few plant fibers, but a lot of animal fats and proteins. One of the consequences is a high level of bowel cancer, 65 cases per 100 inhabitants. But where they eat rough, low-fat foods with a lot of fiber, for example, in rural areas of South Africa, the incidence rate is only 5 people per hundred (100) thousand.

Researchers from the University of Pittsburgh, led by Professor Stephen O'Keefe, together with colleagues from King's College London, conducted an experiment involving twenty black volunteers from the United States and South Africa. During the examination, every second American found polyps in the intestines, which may well develop into malignant tumors. Africans didn't have that. Then the participants in both groups changed their diet.

The result amazed the researchers: in the first, inflammatory processes began to decline, and biomarkers of the risk of developing cancer, which is determined by the composition of intestinal mucus, decreased sharply. The latter, on the contrary, grew sharply. And all this in just two weeks! By itself, the effect of changing the diet has long been known - for example, in Japanese who moved to live in Hawaii and became addicted to American food, in just one generation, a low incidence of bowel cancer changes to a high one.

"The rapid westernization of African lifestyles in response to these data is alarming," says Prof O'Keeffe. "On the other hand, the fact that a traditional African diet high in fiber reduces risk in just two weeks may be a good sign that never will." It's not too late to reverse the process."

The reason is considered to be a significant increase in the production of butyric acid and its derivatives by intestinal microbes during the assimilation of dietary fiber: these substances inhibit tumor cells and promote the development of normal epithelial cells.

Dietary fiber - cellulose, lignin, pectin and other polysaccharides that are not digestible, but good for health - this is what bran, dried apples, apricots and raisins, black bread, fried mushrooms and other plant products are rich in primarily.
