Focus Description:

The focus finger burns without causing harm.

Focus secret:

To demonstrate the focus, you need a flesh-colored cap on the upper phalanx of the index finger. It can be made from bone or other suitable material. On one side, at the base of the cap, there is a tiny movable wheel with flint from a lighter (Fig. a).

Focus Fireproof Finger

Such a cap on the finger will be completely invisible. The incendiary device, of course, should be on the opposite side from the audience.

Lightly moisten the outside of the cap with clean gasoline before showing the focus. If we now stretch the index finger up, while imperceptibly spinning the wheel with the thumb, then the gasoline will ignite and the audience will see a "fireproof" finger (Fig. b).

To put out the fire, you should either blow it out or close it with a handkerchief, and along with the handkerchief, get rid of the cap.

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. With a thickness of just 11,26 mm and a weight of 141 grams, this portable power bank fits easily into a pocket or bag, making it ideal for travel and everyday use.

The new product supports wired charging with a power of 25 W and wireless charging up to 15 W (and up to 30 W when connected to an adapter), providing fast charging for both the power bank itself and other devices. The battery is compatible with various fast charging protocols such as SCP, UFCS and PD, making it ideal for a wide range of devices. 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 ... >>

Skin rejuvenation for 30 years 14.04.2022

The researchers rejuvenated the skin cells of a 53-year-old woman, making them the same as those of a 23-year-old.

Scientists from the University of Cambridge have achieved incredible results: they were able to make human skin cells look younger by as much as 30 years. Scientists believe that they can do the same with other tissues of the human body. Thus, it is possible to develop treatment for diseases that occur in older people.

The origins of the method used by scientists in the new study date back to the creation of the cloned sheep Dolly in the 90s of the last century. Then scientists wanted to create the so-called human embryonic stem cells. They hoped that in this way they could be grown into certain tissues, such as muscles, cartilage, and nerve cells, to replace worn-out body parts.

In 2006, Japanese scientists came up with a new method they called IPS. With it, scientists added chemicals to the cells of an adult organism for about 50 days. This led to genetic changes that turned adult cells into stem cells. But then it was necessary to grow these stem cells into cells and tissues that a person needs. But after so many years, this has not yet yielded the desired results.

Wolf Reik and colleagues used the IPS method on the skin cells of a 53-year-old woman. But now, in the lab, scientists have added chemicals to cells not for 50 days, but for 12. These cells did not turn into embryonic stem cells, but rejuvenated and began to look and behave like they belonged to a 23-year-old girl. But this method cannot be immediately transferred from the laboratory stage of research to the clinical stage, because the IPS method increases the risk of developing cancer.

Now that it is known that cells can be rejuvenated, an alternative, safer method can be found to create the necessary human tissues to improve health, not life expectancy.

"At a minimum, we can start by developing drugs to rejuvenate the skin of older people where this skin has been damaged. And then we will check whether our new method can be applied to other human tissues," says Reik.

Scientists say that it will be possible to try to rejuvenate immune cells so that with age a person can better cope with diseases. The question of creating an anti-aging drug is not yet on the table. But perhaps new research will lead to the fact that it will be possible to achieve regeneration of the entire body, and not of its individual sections.
