Blinking of the magician and his audience

19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience.

Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick.

The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences.

Additional research has shown that magicians blink more frequently during complex tricks, which may be a strategic technique to keep audiences' attention. Ultimately, these findings highlight the importance of nonverbal interactions between magicians and their audiences, expanding our understanding of the processes that occur during magical performances.

Improving the efficiency of PbS quantum dot solar cells 14.06.2024

The latest solar technology research represents a significant breakthrough in improving the efficiency of PbS quantum dot solar cells. This method, based on the use of pulsed light, offers promise for simplifying the production and expanding the applications of these cells. A research team from the Daegu Gyeongbuk Institute of Science and Technology has developed an innovative method that uses pulsed light to improve the electrical conductivity of PbS solar cells. This method can significantly reduce the processing time required to achieve similar results. PbS quantum dot solar cells have significant potential in solar technology due to their photovoltaic properties. However, the formation of defects on their surface can reduce their performance. The new method helps suppress defect formation and improve electrical conductivity. Using strong light to complete the process ... >>

Magnetic Power Bank 5000mAh 14.06.2024

Huawei introduces a convenient and multifunctional charger to the market - Huawei SuperCharge All-in-One Magnetic Power Bank. This magnetic battery allows you to quickly and conveniently charge your Huawei phone anywhere, anytime.

The power bank is also compatible with Huawei phones that support wireless charging. ... >>

Changes in a father's brain after the birth of a child 13.06.2024

A recent study conducted by scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences found interesting changes in the brains of men after becoming fathers. These changes were associated with involvement in child care, sleep problems, and mental health symptoms. Scientists found that men who became fathers experienced a loss of brain volume after giving birth. This volume loss was associated with greater involvement in parenting, sleep problems, and mental health symptoms. Researchers have found significant changes in men's brains between the prenatal and postnatal periods. In particular, there was a loss of gray matter volume, especially in parts of the brain responsible for higher functions such as language, memory, problem solving and decision making. Men who paid more attention to their children and spent more time with them lost more gray matter in their brains. This also affected their mental health ... >>

Smartwatch that analyzes the composition of sweat 13.06.2024

Scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences presented an innovative smartwatch that can analyze the composition of sweat. This device can be a valuable tool for athletes, allowing them to monitor changes in the body during training and competition. The device is equipped with various sensors that can process sweat from the human body and analyze the chemicals in its composition. Using sensors, you can accurately determine the levels of potassium, sodium and calcium ions. Sweat composition indicators can be monitored both in real time and over a period of six months. This allows athletes to receive continuous feedback on the state of their body during training and recovery. Smartwatch sensors are based on electrochemical methods and use a microfluidic chip that can process very small volumes of liquid. This makes it possible to study the composition of even 0,01 ml of sweat. Stability of sensors is a key aspect ... >>

Wine is safer than beer 12.06.2024

A University of Adelaide study has found that drinking alcohol in moderation may be less harmful to heart health than previously thought. Researchers have studied the effects of different types of alcohol on the risk of developing atrial fibrillation (AF), one of the most common forms of arrhythmia that can lead to serious heart complications. Atrial fibrillation is an irregular and rapid heartbeat that increases the risk of stroke, heart failure and other serious heart problems. Symptoms may include rapid heartbeat, shortness of breath, and weakness. Excessive alcohol consumption is known to increase the risk of developing AF, but the effect of small doses of alcohol remains unclear. The study was based on data from the UK Biobank, a large-scale database containing health information on half a million British volunteers. The study's lead author, Samuel Tu from the University of Adelaide's Center for Heart Rhythm Disorders, reports ... >>

Chocolate in the morning helps women lose weight 09.04.2022

Chocolate is a product that has millions of fans around the world. The composition of sweets loved by many includes cocoa butter and grated cocoa, on which both health benefits and harms depend.

It is difficult to count all the useful properties of chocolate. Among the main ones - it is able to increase the level of emotional state, reduce the risk of cardiovascular diseases and the amount of harmful free radicals in human blood.

However, we must not forget that the uncontrolled eating of cocoa sweets will have the opposite effect on health. The result can be a rash, and in other cases, a favorite treat can cause tachycardia and increase blood pressure. Of course, the dosage is of great importance: if you consume chocolate in large portions (more than 100 g per day), then all the beneficial properties of sweets can disappear in an instant, causing great harm to the human body.

Postmenopausal women who eat a small amount of chocolate at breakfast every day find it easier and faster to lose weight, according to a study from Harvard Medical School and the Spanish University of Murcia.

The experiment lasted exactly two weeks. Voluntary participants in the study were three groups of 19 postmenopausal women. Women from the first group ate foods typical for many in Spain, representatives of the second group received approximately 100 grams of milk chocolate within an hour after waking up, and participants in the experiment from the third group ate chocolate in the same dosage, only an hour before bedtime.

In women who ate chocolate in the morning, the weight did not change, but the composition of the intestinal microbiota and other indicators improved. They also recorded a decrease in waist and glucose levels. And the number of calories consumed decreased by 16%.

For the better, the indicators of those who ate chocolate in the afternoon also changed. The women in this group had an average increase in physical activity the next day by 6,9%, as well as a decrease in their appetite and cravings for sweets.

The main conclusion reached by scientists during the experiment was that women who ate a 100-gram chocolate bar every day did not gain weight. This debunks the main myth that chocolate is the enemy of a beautiful figure.
