What is laughing gas?

It's nitrous oxide20, discovered by the English chemist G. Davy back in 1799. At one time it was used in dentistry to relieve patients' fear of the dentist. In 2002, the Pentagon ordered ammunition in the form of capsules with this gas. When it hits a person, the capsule is destroyed and he is covered with uncontrollable laughter for a period of several seconds to three minutes.

What is heredity?

Every organism, be it a plant, a fish, an animal, or a human being, resembles its parents, but is nevertheless different from them. For example, children may resemble one parent or the other, but they usually share some of the traits of each parent. The thing is that parents pass on certain properties to children, and children "inherit" them. So, heredity is the study of how offspring acquire resemblance to their parents. The unit of heredity is called a "gene".

Genes are large molecules found in the nuclei of both sperm and egg cells. Inside the nucleus of each cell are long thin spirals or threads. They are called chromosomes and carry genes. Since chromosomes occur in pairs, their genes are also paired. A cell's chromosomes can contain hundreds of thousands of pairs of genes. Each gene pair controls one or more characteristics of an organism, such as hair color, nose shape, body size, etc.

There are many laws of heredity, which means that the process occurs in certain directions. For example, each trait that is inherited depends on a simple "factor", and each factor behaves independently. Because certain traits are inherited from parents, this does not mean that every other trait will inevitably be inherited as well.

In other words, factors or genes are not related to each other. Some genes are dominant while others are recessive. For example, the genes for curly hair are dominant over the genes for straight hair. When both parents are curly, they usually have curly children as well. But if every parent carries the recessive gene for straight hair, some children may have straight hair. Scientists have studied human traits such as eye, hair, and skin color, so they can usually tell how such traits are inherited by people whose family histories have been known for generations.

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 ... >>

Pocket Particle Accelerator 16.08.2020

Researchers have developed a compact particle accelerator that uses a laser to accelerate electron beams up to 99,99% of the speed of light.

To achieve this result, scientists from the University of Manchester have developed a special metal structure coated with layers of quartz thinner than a human hair, as well as light pulses in the terahertz range. The generated radiation exists in an ideal millimeter-scale wavelength mode, which is well suited for accelerating highly charged particles.

The main problem was to match the speed of the accelerating THz field with the speed of the electron beam at almost the speed of light, and also to prevent the initially lower speed of the terahertz pulse propagating through the structure. Scientists have solved this problem by developing a unique radiation source that generates longer pulses containing only a narrow range of frequencies.

Experts are already working on increasing the energy of the radiation source while maintaining the quality of the beam. The new technology will replace billion-dollar kilometer-long accelerators with devices that are only a few meters long.
