Human crises

25.02.2019

American scientists have named the most depressive age in a person's life, when the feeling of loneliness is especially developed.

Researchers at the University of California conducted an experiment in which they observed volunteers. They managed to find out that almost every person goes through a period when life is not sweet. It is during this period that the feeling of loneliness and mood swings are especially pronounced.

After a series of observations, they accurately determined that the age of 25 to 30 is considered the most critical age. It is during this period that many people think about the correctness of their choice and the future in general.

The second crisis period is 50 years. Here, too, it is easy to explain why a person falls into depression. He has grown children and started families of his own. At the age of 50, a person begins to feel the bitterness of disappointment and regret - unfulfilled dreams, unjustified hopes, fear of old age, concern about health.

And finally, scientists call 80 years the third depressive age. No longer old age, but decrepitude, poor health, loss of loved ones. A constantly depressed state simply hits the body and greatly depletes the immune system.

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 ... >>

Robots can read your mind 06.07.2018

With the help of a new robot control system, a human can prevent a machine error and redirect it using brainwaves and simple gestures. People who control robots in factories, homes or hospitals will be able to use the installation.

MIT AI specialist Daniela Rus and her colleagues tested the system with seven volunteers. Each user controlled a robot that moved the drill to one of three possible targets, indicated by an LED light on the model aircraft's fuselage. Whenever the robot started moving towards the wrong target, the error signal from the user would stop it. And when the user turned their wrist left or right to redirect the robot, the machine moved towards the corresponding target. Out of more than 1000 trials, the robot initially selected the correct target about 70% of the time, and after human intervention, more than 97% of the time.

The team plans to create a system version that recognizes a wider range of human movements. In this way, "you can show how the robot should move, and your movement can be interpreted more quickly," says study co-author Joseph Del Preto, also an artificial intelligence specialist at the Massachusetts Institute of Technology.

Commands through the brain and muscle activity can work particularly well in noisy or poorly lit environments, such as factories or outdoor venues. In such areas, other means to manually control robots, such as visual cues or verbal instructions, may not work, says Alexander Barachant, a researcher at New York-based startup CTRL-Labs. This method can also be used by people who cannot speak or move, such as patients with amyotrophic lateral sclerosis.

Moreover, the system is able to correct robot errors almost instantly. The potentials associated with errors in the brain are noticeable several hundred milliseconds after a person notices an error, and muscle electrical signals can be detected even before the actual movement, Barachant explained. This feature can be useful in situations where responsiveness is very important for the safety of the robot and other people - both for unmanned vehicles and production machines.

For this system to be widely used, equipment that tracks users' brain activity needs to be more widely available than it is now. This mind control device can cost thousands of dollars, and electrode caps are hardly the most comfortable headgear. But if researchers could measure the brain signals with cheaper and more comfortable headsets, the system could provide a relatively quick and easy way for regular users to get the robot to fulfill their requirements.
