What is a sleep disorder?

Sleep disorder is a very serious disease. It is distributed mainly in Africa among people and animals. The infection is caused by parasites called trypanosomes. Their peddler is the tsetse fly, well known in many parts of central Africa.

Tsetse carries parasites when it bites a sick person or animal. Trypanosomes enter the insect's stomach and begin to multiply. Then, through the salivary glands, they enter the mouth of the insect. Here microbes develop to such forms that they can infect a person.

At the moment of an insect bite, parasites get under the skin of a person. A tiny sore appears. For the next three weeks, trypanosomes circulate in the blood. At this time, the infected person begins bouts of fever, often the skin becomes covered with a rash. The brain is slightly swollen.

In some parts of Africa, the infection ends and the patient recovers. But in Zimbabwe and Malawi, the disease is more serious. Within a year, the patient develops symptoms of brain damage. The patient experiences a severe headache, becomes excitable, uncontrollable actions appear.

Then comes the next stage. The patient becomes very calm and falls asleep. He has been unconscious for a long time. The patient is still feverish. Finally, paralysis sets in, the body is extremely exhausted, and death occurs. The cause of unconsciousness is the penetration of infection into the cerebral cortex. There may be other causes of brain inflammation.

The described disease is called "encephalitis". African sleep disease is just a severe form of encephalitis. It should be noted that the microbes that cause sleeping sickness are not transmitted by tsetse to offspring. Thus, death by bite occurs only if the tsetse fly has previously bitten a sick person or sick animal.

 Random interesting fact from the Great Encyclopedia:

How could so many samurai be forced to kill themselves at the same time?

According to bushido - the code of honor of the samurai - his life belonged entirely to the owner. In medieval wars, it was enough to kill the owner for all his samurai to commit "suicide after" ("junshi").

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Drones can smell 05.12.2020

University of Washington engineers connected a live moth's antenna to an electronics suite and used it to point the drone at specific smells. They call the created machine Smellicopter.

"Nature is head and shoulders above our artificial odor sensors. By using the olfactory antenna of a real moth on a Smellicopter drone, we can get the best of both worlds: the sensitivity of a biological organism on a robotic platform that can be controlled," says Melanie Anderson, lead author of the study.

The hollow tubular antenna is borrowed from the tobacco hawk moth (manduca sexta). Small electrodes are inserted into each end of the antenna, which pick up the signal from its receptors. The antenna remains biologically and chemically active for up to four hours after removal, but its shelf life can be extended if the component is refrigerated.

To test the resulting cyborg's sense of smell, the team placed the sensor in a wind tunnel, where it had to compete with a standard artificial smell sensor. Tests have shown that the moth's antenna reacts to the smell of flowers or ethanol much faster than any other sensor.

In the following experiments, the researchers mounted the sensor on a small quadcopter equipped with two plastic fins that allow the car to navigate with the wind and four infrared obstacle detection sensors.

The Smellicopter is powered by an algorithm that mimics the flight of a butterfly. The drone starts flying by drifting to the left for the specified distance. If it doesn't detect a strong enough odor, it changes course and moves to the right. Having detected the smell, the drone flies to its source. If at any time the infrared sensors detect an obstacle within 20cm, the Smellicopter will change direction.

The device can be used to detect explosives or the breath of people stuck under rubble at disaster sites.
