Focus Description:

The match dances right in your hands!

Focus secret:

You will need 2 matches. We take one with two fingers - forefinger and thumb - and squeeze it tightly. We put the middle of the match on the nail of the middle finger (fingers pointing up) and also firmly press it to the nail. We put the second match on top of the first, lightly support it with the fingers of the second hand and begin to slightly push the first match up along the nail (the stronger the match is pressed, the less noticeable its movement).

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 ... >>

Raised mice with human cells 13.02.2019

In China, a team of scientists has grown mice that have human immune cells working inside. They took this step in order to more carefully analyze all the consequences of hepatitis B.

Up to this point, researchers have not been able to adequately model hepatitis B infection in mice, as the disease almost exclusively affects humans. However, they were able to establish that human stem cells can divide into hapatocyte-like cells, continue to live and perform liver functions even after transplantation into a mouse liver. During the experiment, hepatocytes occupied 70-80% of the liver mass.

Chinese scientists infected these humanized rodents with the hepatitis B virus. As a result, they developed special reactions very similar to those of humans. Symptoms of chronic cirrhosis and hepatitis were also observed.

In the future, with the help of humanized animals, the research team plans to further understand the pathophysiology of the virus, as well as test antiviral drugs.
