Which angel originates from the devil?

The world's highest waterfall Angel (meaning "angel") falls down from the top of Auyantepui. This name is translated from the language of local Indians as "mountain of the devil."

Authors: Jimmy Wales, Larry Sanger

 Random interesting fact from the Great Encyclopedia:

What is the most dangerous animal that has ever lived on our planet?

A good half of the people who have died in the history of mankind - something like 45 billion - were killed by female mosquitoes (males only bite plants).

The mosquito (or mosquito) carries over a hundred potentially deadly diseases, including malaria, yellow fever, dengue, encephalitis, filariasis, and elephantiasis (elephantiasis). Even today, every twelve seconds, this insect kills one of us.

Amazingly, until the end of the 1877th century, no one could have thought that mosquitoes were so dangerous. It wasn't until XNUMX that Dr. Sir Patrick Manson - also known as "Mosquito" Manson - proved that elephantiasis was caused by mosquito bites.

Seventeen years later, in 1894, Manson had the idea that mosquitoes might also be the cause of malaria. He invites his student Ronaldo Ross - at that time still a young doctor practicing in India - to test this hypothesis.

Ross was the first to show how a female malaria mosquito transmits the Plasmodium parasite through her own saliva. He tested his theory on birds. Manson outdid the student. To demonstrate the work of the theory, he infected his own son - using malarial mosquitoes, which he brought from Rome in diplomatic luggage. (Fortunately, after an immediate dose of quinine, the boy recovered.)

In 1902, Ross received the Nobel Prize in Medicine. Manson is elected a Fellow of the Royal Society and knighted. He also becomes the founder of the London School of Tropical Medicine.

To date, 2500 species of mosquitoes are known, 400 of which are members of the Anopheles family, and 40 of them are capable of transmitting malaria.

Females lay their eggs in water and use the sucked blood to mature them. The eggs hatch into aquatic larvae, or pupae. Unlike most insects, mosquito pupae, also known as "twitchers", are very active and can glide through the water quickly.

Male mosquitoes buzz in a higher tone than females and can be tempted by a common tuning fork that produces a si note.

Female mosquitoes are attracted to moisture, milk, carbon dioxide, body heat, and movement. Sweaty people and pregnant women are much more likely to be bitten.

In Spanish and Portuguese, the word mosquito means "small fly".

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

The pants of the emperor are being studied 01.05.2006

Swiss surgeon Alessandro Lugli, who works at the University Hospital of Basel, is interested in the history of Napoleon.

As you know, the self-proclaimed Emperor of France died in exile on the island of Saint Helena at the age of 52. The autopsy performed by his personal physician was done at a level quite worthy of modern doctors.

The cause of death was stomach cancer. Nevertheless, for almost two centuries, various other assumptions have been put forward about Napoleon's fatal illness. Lugli decided to confirm the conclusion of the emperor's personal doctor. Gastric cancer is characterized by rapid weight loss shortly before death. Data on Napoleon's weight does not exist, but Lugli measured the waistband of 12 pairs of Napoleon's trousers, including the last one. Knowing the height of a person, by the volume of the waist, you can calculate the weight.

The results of the study showed that while in exile, Napoleon put on weight, but in the last six months he began to lose a lot of weight. The waist has shrunk nearly five inches, which equates to a 20-30 pound weight loss.

"We can't say that these data are enough to make a diagnosis of stomach cancer," Lully says, "but they strongly support the autopsy results." Of course, it would be interesting to follow the changes in the waist of Napoleon during the Russian campaign, but, apparently, these studies are still ahead.
