Hey everyone! How many times did mothers tell us in childhood that when we went out into the cold we would dress warmly - otherwise we would catch a cold. For quite some time, scientists were able to determine that human colds begin because of rhinoviruses, which cause inflammation of the upper respiratory tract. So who is right - science or our mothers? Research For a long time it was known that rhinoviruses reproduce most successfully in the human body if they are in a cold place. For example, in the respiratory nasal passages, which do not warm well in the cold...

Hello friends! Boomerang is still haunted by many generations of scientists. To explain his flight proved to be far from simple. What makes this simple device make an intricate flight? Only aerodynamics can give an answer: after all, a boomerang launched in a vacuum would fly like an ordinary stone, obeying only gravity. They throw a boomerang, giving it a high speed (up to 100 kilometers per hour), keeping it strictly upright and reporting fast rotation (about 10 revolutions per second). First,...

Hello! In the 17-18 centuries, marked by the rapid development of archeology, scientists first suggested that once a large part of the planet was under ice cover. They were prompted by the idea of studying the huge boulders scattered not far from the mountains - whole pieces of rocks, it is not clear how they ended up there. It became obvious that these rocks could be brought in the only way - together with glaciers slowly creeping from the mountains. Period Definition Subsequently, detailed studies of this issue confirmed the assumptions of scientists...

Greetings friends! Nothing portended danger. The spacecraft was the most reliable of all that has ever been made on Earth. A special system protected him from meteorite and radiation hazards. The crew consisted of the most experienced astronauts. The flight safety guarantee seemed to be complete. But the misfortune did not come from where they could have expected him ... In the second month of the star expedition, one of the crew members fell ill. A week later, went to bed another. The doctor took a sample of air and grabbed his head in horror...

Hello everyone, friends! Laughter is a person's reaction, which is accompanied by involuntary contractions of the muscles of the face, as well as the respiratory apparatus, by involuntary sounds. These reductions can be caused by humor, tickling, sincere joy. Why do you need laughter? What purpose does such an unusual state of the body serve, and why did nature give it to man? We will talk about this in this article. Way of communication It is believed that laughter developed at the very dawn of becoming a rational person...

Hi! Neanderthals are representatives of the hominid family from the genus of humans, extinct about 40,000 years ago. For a long time, Neanderthals were considered the ancestors of modern people, but genetic studies have shown that Neanderthals are a separate evolutionary branch that lived in the same time interval with homo sapience. But a reasonable man could survive to this day and inhabit the entire planet, but the Neanderthal man did not. Scientists still can not come to a consensus on what caused this species to disappear...
