Brain without immunity

02.11.2015

Disease or damage to the brain is the subject of much modern research and invention. One of the latest is a flexible sensor that senses touch and, like skin, sends electrical impulses to the brain. Moreover, the stronger the pressure on the "digital skin", the greater the speed of the pulses becomes.

The difference between this device and its predecessors is its ability to transmit electrical impulses directly to the brain in a format understandable to our gray matter. Existing sensors embedded in artificial or "digital" skin have already demonstrated their impressive capabilities in working with the brain. However, a computer or processor was required to translate their touch signal into the desired format. The new device dispenses with an external processor by using a built-in printed electronic circuit that processes the signal at the moment of touching the "skin" and immediately sends it to the brain in the desired format.

However, the secrets of the brain have not been revealed, not only to the end, but also to any significant extent. For example, the concept of a cure for schizophrenia remains a subject of controversy because there is no generally accepted definition of the concept. What can we say about prevention! However, thanks to the efforts of scientists from the Clinical Sciences Center of the UK Medical Research Council, there is hope in patients suffering from this disease. Studies have found overactive immune systems in such patients, and in addition, increased activity was observed in patients at high risk of schizophrenia.

Suspicions fell on microglia, a specialized class of glial cells in the central nervous system that are phagocytes that destroy infectious agents and destroy nerve cells. This last property of microglia, more precisely, its ability to destroy connections between brain cells for the general protection of the body, leads, according to scientists, to the formation of incorrect connections in the brain, which causes schizophrenia. The researchers plan to test weak anti-inflammatory drugs on patients that would help the immune system cope with its functions more easily without destroying nerve connections.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Homemade submarine 14.11.2007

A shipbuilding engineer from Kiel (Germany) Michael Schmelter built a two-seater submarine. The case, made of 32 mm thick fiberglass-reinforced plastic, can theoretically withstand diving up to 450 meters, but for safety reasons, the diver does not go deeper than a hundred meters.

The air supply lasts for 12 hours. The boat weighs two tons, of which almost a ton is the weight of the lead ballast. Ballast tanks take 250 liters of water, for ascent it is pushed out by compressed air. The movement is provided by four electric motors. The batteries have enough energy for five hours of constant swimming. The engineer has already made more than a hundred dives in the Kiel Bay on his boat.

The construction took 2000 working hours and cost 40 euros.
