Focus Description:

You have a top hat on your head. Remove it and place it on the stand in a horizontal position. Then take out a faucet (of course, its imitation) from your pocket and attach it to the base of the cylinder.

After that, bring an empty glass to the tap. With the other hand, open this faucet - real water will begin to pour into the glass from it.

Focus secret:

In the hand that opens the faucet, there is a rubber bulb filled with water. Squeezing this pear, you pour water from it directly into a glass.

Focus Water from Cylinder

The faucet is attached to the base of the cylinder with a small hook on the faucet and a loop on the cylinder, or with a pin attached to the faucet and bent slightly to the side.

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 ... >>

Habits change the brain 03.02.2016

A habit is a deeply rooted type of behavior that works independently of our consciousness. We automatically find the way to the kitchen in the morning, automatically find, for example, a kettle, automatically enter the transport (or get into the car), and do not really think about what we are doing.

It is believed that habitual actions help unload the brain from routine, allowing it to do something more important. That is, from the point of view of neurophysiology, the resources of the prefrontal cortex, our main analytical center responsible for, let's say, conscious life, are unloaded. The habit itself goes into subcortical structures called the basal ganglia, or basal ganglia. (Let's clarify that now we are talking about harmless behavioral rituals, and not about addictions to alcohol, nicotine, etc.) ganglia, and the formation of a habit is accompanied by changes in electrical rhythms: gamma waves that occur during the development of new information are replaced by beta waves when the material is consolidated.

But what happens in the brain, in its basal ganglia, after the habit has already been formed? Neuroscientists from Duke University tried to answer this question: laboratory mice were taught that if they press the lever of a device, they will get something sweet; as a result, some animals continued to press the lever even after the treat was removed from the device. Further, the work of the brain of mice with the habit of pressing the lever was compared with the work of the brain of mice, which understood that there was nothing to wait for and ceased to be interested in the lever.

The basal ganglia control motor activity and literally control our desires, addictions, etc., that is, if we smelled a cake from somewhere that we are crazy about, then it is the basal ganglia that will command us to go where it smells and try do whatever it takes to get food. However, the ganglia generate not only stimulating impulses, but also suppressing, prohibiting ones; that is, the fulfillment of desire ultimately depends on the balance between opposing signals in the basal ganglia. For example, if it’s too dangerous ahead, then, no matter how delicious it smells, you shouldn’t go there, and the neural stop signal is just right here.

So, in mice with a habit of pressing the lever, both signals of the basal ganglia, both inciting and forbidding, increased, however, compared with normal mice, in these mice, the inducing signal became the first by default. That is, if in ordinary animals the basal ganglia “understood” that there was nothing to wait for in this situation and brought to the fore the suppressive impulse that forced them to ignore the lever on the distribution of treats, then in mice with the habit, the stimulating signal in the subcortical structures continued to stimulate attempts to receive treats. .

Changes in brain function persisted for quite a long time, and it was possible simply by the behavior of neurons to predict what this or that mouse would do. The researchers also specifically note that such a rearrangement of signals in places did not occur in any particular group of neurons, but throughout all the basal ganglia (this probably explains why craving for one thing is the reason for a whole bunch of not always healthy habits).
