Computer mouse will evaluate health

17.04.2000

The latest innovation from Almaden Research Center is the Emotion Mouse. The device is an ordinary mouse with a copper coating on the buttons and an IR source.

Thanks to these "additions", the mouse allows you to determine the heart rate, temperature and electrical conductivity of the skin, as well as register the micro-movements of the user's fingers, whose psycho-emotional state is determined by a special program.

To obtain the final result, the user must solve puzzles and view computer comics for half an hour.

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 ... >>

Flies help alcoholics 11.10.2019

Everyone knows the effect of alcohol on the human body - however, even the most experienced and qualified neuroscientists cannot fully unravel the mystery of what exactly happens to the brain during intoxication. Traditionally, ethanol molecules were thought to directly affect nerve cells in the brain, but a new study from the Scripps Institute has shown that several other molecules are also involved in this process, making the process of intoxication and subsequent hangover more complex from a neurobiological point of view. In particular, experts conducted several experiments on fruit flies, inducing ethanol to them.

By observing flies, experts have found that they also go through the same phases of intoxication as humans - however, along with this, experts also noticed a new molecular mechanism. At the moment when the ethanol molecules reach the nerve cells of the brain, an enzyme called phospholipase D2 comes into play, which connects the ethanol molecules and lipids to each other, creating an alcoholic lipid metabolite called phosphatidiletanol PEtOH.

Reviewing this enzyme, experts came to the conclusion that its construction and “piling up” in nerve cells in large quantities leads to the subsequent process of their activation and movement, which is expressed in the hyperactive phase - however, after it comes the phase of anesthesia, so named because it is very similar to the action of medical anesthesia.Thus, experts were able to reveal in more detail the features of the process of intoxication, which in theory will deepen the understanding of this process.

And this, in turn, can help develop more effective anti-hangover drugs and therapies - after all, scientists say that such an indirect process in its deployment probably hides many more sides and interesting aspects that they can only guess about. Be that as it may, the preliminary experiments on the first batch of flies will soon be over, and the experts will begin a more detailed analysis of what they managed to collect during the experiments.
