Who lost the chance to become a head of state by wanting to visit Disneyland?

Kim Jong Nam, the eldest son of Kim Jong Il, was educated in Switzerland, then worked in high government positions and was considered the heir to the post of Great Leader. His relationship with his father soured in 2001 when Kim Jong Nam, accompanied by two women and a small boy (probably his son), tried to enter Japan on a fake Dominican passport. The alleged purpose of the visit was to visit Tokyo Disneyland. After that, the failed successor settled in China, and power in the DPRK since 2011 passed to his half-brother Kim Jong-un. In 2017, Kim Jong Nam was killed by a woman who threw a poisoned handkerchief over his head.

Random interesting fact from the Great Encyclopedia:

What weighs more - the food consumed by a person per day, or the air that he inhales over the same period of time?

The weight of air inhaled and exhaled by a person during the day is easy to calculate.

With each breath, a person introduces about half a liter of air into their lungs. This is done on average 16 times per minute. This means that in one minute about 8 liters of air manage to visit the body. This is approximately 480 liters per hour, and 11 liters per day. This volume of air at normal pressure weighs about 500 kilograms.

Thus, per day, a person passes through his body much more air than food: on average, during this time, the body consumes about 3 kilograms of food (solid and liquid). However, if we take into account that the inhaled air consists of 4/5 nitrogen, which is useless for breathing, it turns out that the daily weight of its remaining components is approximately equal to the daily weight of the food consumed.

The given estimates are a convincing argument in favor of the need for fairly frequent air renewal in a residential area.

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 ... >>

Artificial uterus for premature babies 07.05.2017

A plastic container that completely imitates the internal organs of the mother is now being successfully tested on lambs, and they plan to test it on humans within 3–5 years.

The statistics, alas, are sad: among premature babies born at 22-24 weeks of pregnancy, only 10% survive. In addition, these babies have poorly developed vital organs, many of them may develop deafness, blindness or cerebral palsy at first.

Dr. Alan Flake of the Children's Hospital of Philadelphia in the United States, along with his colleagues, has created an artificial womb that will help "carry" a child.

The device reproduces the uterine environment as closely as possible and replaces the function of the placenta. It is a plastic container that is filled with a liquid that mimics amniotic fluid in composition. The baby's umbilical cord is connected to the gas exchange system - it replaces the mother's placenta and supports the baby with oxygen. Unlike incubators, an artificial uterus protects the newborn from infections.

During the experiments, Flake's team placed lambs born at 15-17 weeks (roughly equivalent to human newborns at 21-24 weeks) in an artificial womb. The animals stayed there for 4 weeks, after which they were carefully examined. Test results showed that the lambs had well-formed lungs and brains and were generally healthy.

Alan Flake's British colleagues note that the device he developed can already be called a breakthrough: doctors have been trying to create an artificial uterus for years. However, it is too early to put it into practice - there are several years of laboratory tests ahead. Flake needs to make sure the device is safe for babies. Also, the author of the project wants to slightly modify the device: reduce the size, add several functions and install a camera so that parents can watch how their child develops and feels.
