How long can a person go without food?

Most of us experience discomfort after skipping at least one meal, and if we try to go without food for 12 hours, we will feel completely out of our element. But there are people who seem to be able to "fast" for a very long time.

There are reports of numerous records of prolonged fasting, but in most cases there is no medical evidence, and therefore these records are in doubt. One South African woman even claimed to have taken nothing but water for 102 days.

In terms of the ability to live for some time without food, there are great differences between living beings. For example, a tick that lives on animals can live without food for a whole year. Warm-blooded animals use up their body reserves much faster. The smaller and the more active the animal, the faster it uses up its reserves. A small bird can starve to death in about five days, and a dog in twenty days.

In general, we can say that a warm-blooded animal dies when it loses about half of its normal weight. The weight itself matters a lot. Humans and other living beings live in a state of metabolic equilibrium, which means the need to regain body weight once a certain minimum is reached.

Body weight is regulated by thirst, hunger, appetite. When you lack any nutrients in your blood, this is noted in one of the areas of the brain, and you feel hungry. The body requires any fuel (food). And our appetite makes sure that we choose a diet that meets the needs of our body.

What American president lost the code to open the nuclear suitcase for a long time?

The morning after the Monica Lewinsky scandal became international news, Bill Clinton had an on-duty meeting with the military man responsible for the constant escort of the nuclear briefcase. The officer asked the president for a card with a code to open the briefcase in order to exchange it for a new one, to which Clinton admitted that he had lost this card somewhere. Moreover, he could not remember how long ago he had lost her - perhaps weeks or months had passed since that moment.

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 ... >>

Scientists have discovered diamonds from a dead protoplanet in a meteorite 27.04.2018

A small asteroid 2008 TC3 fell into the Nubian Desert in northern Sudan on October 7, 2008. It was named Almahata Sitta, which means "Sixth Station" in Arabic (this is the name of the railway station, which is located near the place where the meteorite fell). This is the first case in history when a collision of a celestial body with the Earth was predicted: an asteroid was discovered at the Mount Lemmon Observatory (USA, Arizona) the day before the fall. The mass of all its fragments scattered across the desert reaches about three kilograms.

This asteroid is also unique in that it belongs to a rare type of stone meteorites - ureilite, which has a unique mineralogical composition. Ureylite contains a high percentage of carbon, which is contained in the stone in the form of graphite and nanodiamonds - a structure that has a crystal lattice structure similar to diamonds. For a long time it was not known exactly what is the origin of the diamonds found in the asteroid - and, accordingly, the origin of the celestial body itself. The discovery of scientists from the Federal Polytechnic School in Lausanne (Switzerland) sheds light on this event.

In total, three theories of the formation of diamond crystals are known. The first is "shock": inclusions of these precious crystals can form during the collision of celestial bodies. Another says that they are formed due to the chemical deposition of carbon vapor. The third claims that diamonds appeared in the bowels of protoplanets.

Analysis of meteorite fragments found in Sudan shows that the size of some diamond inclusions reaches up to 100 microns. Scientists say that the pressure required to form such large crystals cannot be lower than 20 gigapascals (about 200 thousand atmospheres). Such conditions could only be created on a large planet comparable to Mars or Mercury. Thus, scientists confirmed the third theory and proved that the asteroid is a fragment of an ancient protoplanet.

This find allows us to get closer to understanding how our solar system formed. The researchers suggest that all ureilitic asteroids may be the remnants of the same protoplanet that existed long before the formation of the planets known to us.
