Where and when did the epidemic of laughter break out, engulfing about 1000 children?

In 1962, an epidemic of laughter broke out in Tanganyika (present-day Tanzania), which eventually affected about 1000 people. It began at a girls' school in the village of Kashasha - at first three students laughed, and soon most of the girls were infected with laughter.

Attacks of laughter in each lasted from several hours to several days in a row.

The school was soon temporarily closed, but the epidemic spread to other children and teenagers in 14 schools in nearby villages. The phenomenon finally disappeared 18 months after the first recorded cases.

Random interesting fact from the Great Encyclopedia:

How are icebergs born and how high can they reach?

Icebergs are large blocks (mountains) of glacial ice that float or sit aground in the ocean, sea or glacial lake.

Icebergs are formed as a result of breaking off (under the influence of hydrostatic water pressure, tides, currents and wind) the ends of glaciers descending into the water. The main "suppliers" of icebergs, and the largest ones, are the ice shelves of Antarctica and the northern islands of the Canadian Arctic Archipelago, as well as the Greenland ice cap.

Depending on the density of ice and water, 1/10 to 1/6 of the volume of an iceberg is on the surface. But even this above-water part has an average height of 70 meters (Arctic) to 100 meters (Antarctic). Under the influence of uneven melting, icebergs capsize from time to time.

Greenland icebergs are carried by currents up to 40-50 degrees north latitude, and in some cases even further south. Antarctic icebergs reach 45-60 degrees south latitude, in 1894 they were observed even in the tropical zone.

Collision with icebergs has been the cause of the death of many ships, the most famous of which is the passenger liner Titanic, which sank in 1912.

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 ... >>

Third eye of the frog 07.08.2006

More than fifty three-eyed frogs live in the zoological laboratory of a college in the Indian town of Bikaner.

These strange amphibians confirm the long-standing hypothesis that the pineal gland (the pineal gland of the brain) is associated with the eyes in its origin, is able to respond to light, and under certain conditions can turn into an eye. According to the teachings of the Yogis, this third, "spiritual" eye can be developed by acquiring the ability to clairvoyance through it.

However, zoologist Umbrakash Jangir discovered that if you remove the eyes from tadpoles and add vitamin A to the water, then after ten days the pineal gland turns into an eye. By transplanting the pineal gland of tadpoles into adult frogs and injecting them with vitamin A, the zoologist, without any yoga, obtained three-eyed amphibians and proved the connection between the pineal gland and the eyes.
