Focus Description:

Make an enlarged copy of a needle 10-12 cm long from wood or metal. Insert a rope loop into the eye of this needle so that the loop does not reach the point a little (Fig. a). The puzzle is ready.

Focus Mystery Needle

Now go up to one of the spectators and quickly fasten the needle into one of the loops of his jacket or shirt. To do this, you need:

1) tighten more fabric with a loop into the rope loop;
2) insert a needle into the loop (Fig. b);
3) tighten the rope loop (fig. c).

The task is to remove the needle with the loop without tearing the loop and the jacket.

Focus secret:

If you have learned to do everything quickly, then the viewer will not have time to remember the entire sequence of operations and it will be very difficult for him to solve this puzzle.

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 ... >>

Chemical synthesis against superbugs 27.12.2018

Researchers at the University of Colorado Boulder have developed a new way to synthesize and optimize a natural antibiotic that could one day be used to fight deadly drug-resistant infections like Staphylococcus aureus.

According to the Centers for Disease Control and Prevention (CDC), antibiotic-resistant infections affect more than 2 million people each year and cause more than 23 deaths in the US. A study by European partner CDC in 000 found that drug-resistant superbugs were responsible for 2018 deaths in Europe in 33.

Researchers have previously identified thiopeptides - natural antibiotics - as a promising area of research. Thiopeptides have shown some efficacy against Staphylococcus aureus and some other bacterial species in limited trials, but their structural diversity makes it difficult to synthesize molecules on a scale large enough for therapeutic use.

To make better use of thiopeptides, University of Colorado researchers went back to basics and revisited previous assumptions about the basic chemical properties of these molecules.

Researchers have invented a new catalyst to stimulate reactions that trigger the synthesis of thiopeptides and form the scaffold needed to inhibit bacterial growth. Their efforts have resulted in two new broadly representative antibiotics: micrococcin P1 and thiocillin I. The compounds are effective, scalable, and do not produce harmful by-products.

The new chemical synthesis methodology is just a starting point, the scientists say. He and his colleagues plan to use their findings as a platform for selecting and standardizing thiopeptide moieties in order to optimize their properties and broadly apply them to other bacterial classes.

Antibiotic compounds will need to undergo clinical trials before they are approved for human use - a process that can take many years. Still, Walczak says the need for scientific innovation in antibiotic-resistant superbugs is greater than ever.
