Focus Description:

The magician takes a small plastic bottle, hits the bottom three times and drives a coin through the bottle!

Focus secret:

We take two identical coins. We put one coin into a hole on the side, which must be cut in advance with a knife, and put the other in our hand. When you hit the bottle, the coin that is in your hand, click on the coin that is put in the bottle, and it will fall, and hide the other coin.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Identification by electronic activity of the brain 24.04.2016

American scientists have described a method for identifying people by their "brain imprint" - a unique response to certain stimuli. The CEREBRE method has shown 100% accuracy in determining the identity and in the future can be used to create reliable protection systems.

During the experiments, the researchers developed a Cognitive Event-RElated Biometric REcognition (CEREBRE) protocol. He involved the processing of brain signals associated with the activity of several systems: for example, the primary visual response, face recognition and response to taste stimuli. The study involved 50 volunteers, each of whom was shown 500 images from a specially prepared set, which included images of food, faces, neutral objects, or cards with words. The response of the brain of each of the subjects during the demonstration of pictures was recorded by an electroencephalorophic headset ("helmet", which the subjects had to put on).

The results of the analysis showed that the responses of the brains of different people were unique, and CEREBRE was able to uniquely (with 100% certainty) identify each of the fifty subjects.

Previously, another group of researchers turned to the idea of a "brain imprint", but their study recorded the neural activity of the brain during the performance of certain tasks. Using this approach, it was possible to achieve an accuracy of 80-90%, and the previous best result of the authors was 97% using only words (without images). The researchers emphasize the importance of 100 percent certainty when using "brain prints" to gain access to classified information.
