Why did director John Ford lose the services of a weather forecaster?

Director John Ford often attracted Indians not only as actors for his westerns, but also for other work. When filming Fort Apache, many scenes required certain weather conditions, and Ford began to pay a Navajo doctor to give him forecasts. For several days they definitely came true, but one day the doctor said that he could no longer predict. When asked why, he replied that one actor had taken his radio.

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 ... >>

An artificial analogue of the cells of the immune system has been developed 24.12.2018

Scientists have created an almost perfect synthetic analogue of human T-lymphocytes, which play a key role in the immune system - protect the body from infections and cancer.

The complex structure of T-lymphocytes, until recently, did not allow bioengineers to mimic the similarity of T-cells, which play a major role in the immune system. They are activated when an infection enters the body or malignant cells form. A characteristic feature of cells is elasticity: they can shrink, deform to one quarter of their normal size, or grow several times to protect the immune system, which complicated the task for scientists.

Researchers from the University of California solved the problem almost flawlessly - they were able to reproduce the shape, size and flexibility of T cells. The team fabricated T cells using a microfluidic system by combining two fluids - mineral oil and an alginate biopolymer. As a result, alginate microparticles copied the shape and structure of natural T cells, and elasticity was created by changing the concentration of calcium ions. In order for the cells to behave like real ones and perform all the protection functions assigned to them, they were coated with phospholipids so that their appearance mimics human cell membranes.

"We have been able to create a new class of artificial T cells that can stimulate the immune system. This should be another tool to fight cancer cells and other carcinogens," says researcher Mohammed Mahdi Hasani-Sadrabadi.

Using the same algorithm, other scientists could create new types of artificial cells, the developers say, which could help better investigate specific diseases or help develop new treatments. In the future, this approach should help create a database of synthetic cells that mimic human cells.
