Focus Description:

Twist the paper napkin into a rope as tight as you can. Invite someone to break it (if by chance the viewer manages to cope with such a task, twist the new tourniquet thicker).

While he tries, offer your help. Lightly touch the middle of the napkin and it will tear.

Focus secret:

You need to dip your fingers in a glass of water before touching the napkin, the effect of a drop of water is amazing!

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 ... >>

Harmless bacteria become deadly 24.02.2016

For the first time, scientists have compared all known species of Leptospira bacteria: some representatives of this genus cause deadly diseases in humans and domestic animals. Microbiologists have figured out what makes bacteria harmful.

Some species of Leptospira do not cause infections and feed on the decay products of living things. In rats and mice, they live in the kidneys. In cows, sheep, pigs, and horses, leptospira sometimes causes kidney failure and cardiac arrest, as well as miscarriages. In humans, leptospirosis (a disease of swineherds) results in flu-like symptoms. In more severe cases, microbes infect the kidneys, liver, and central nervous system. Up to 60 people die from this disease every year.

Scientists have identified unique proteins characteristic of pathogenic Leptospira species. This discovery will help develop a vaccine against leptospirosis. In addition, a unique mechanism for protecting the microbe was discovered: it synthesizes sialic acid, which allows you to hide inside the body from cells of the immune system. Further, dangerous species of bacteria in the course of evolution have learned to synthesize vitamin B12 from a single precursor (amino acids).

Finally, the CRISPR-Cas genetic mechanism was found in pathogenic species, which has recently been actively used for genome editing. CRISPR-Cas gave leptospiras increased resistance to invasion by foreign genetic elements.
