A hundred years ago in Soviet stores you could see unusual bottles in the form of a triangular prism. In this form, pure acetic acid was sold, which is a very dangerous chemical element for human health. Manufacturers of acid, taking care of consumer safety, poured it into containers significantly different from other glass bottles — even in the dark, a person could determine the unusual shape of the glass container and accidentally not drink its contents or add acid to where it was not needed.

Why do wine bottles have a concave bottom? Four reasons. Firstly, transportation: bottles of this shape were more convenient to transport on bad roads, because the bottom of one can hold the neck of the other. Secondly, the sediment: with this shape of the bottom, it rolls down and is visually not so noticeable. Thirdly, it was much more difficult for glassblowers to make the bottom perfectly smooth with manual labor. And, fourthly, the concave bottom has less contact with the surface, which makes the bottle more durable, and it also creates a «stiffening edge» from the bottom of the glass container.

British biologists studied a group of bottlenose dolphins living off the coast of Scotland. They recorded that animals «pronounce» certain sounds when relatives approach, and everyone in the family has a name by which others address him. When the recordings of the «speech» of relatives were turned on, dolphins willingly swam up to the team of scientists and «answered» to the «words» of relatives, while the voices of mammals from other flocks were apprehensive and did not enter into a «dialogue». In addition to names, dolphins use more than 14,000 sound signals in communication.
A naked digger is not afraid of pain, does not get cancer and does not age. Scientists are trying to unravel the secret of its genome in order to use it to fight cancer and prolong human youth. He was irradiated, watered with acid and created all kinds of negative living conditions, but only two cases of malignant tumors have been recorded in the entire history of research. The life span of a digger can reach 30 years — although rodents usually live no longer than 4-5 years. They are even able to go without oxygen for a long time.

Everyone knows about the unique medicinal properties of honey, but the fact that honey is the only food product that never spoils makes it truly special. Sugar, lack of moisture and an ideal level of acidity is a formula that protects honey from harmful bacteria, which cause the rest of the products to disappear.
