Focus Description:

There is a seemingly ordinary candle on the table. “Now I will light it with one touch of the magic wand,” you say addressing the audience, make magical passes, and touch the candle with the magic wand. To the amazement of the spectators, the candle immediately lights up!

Focus secret:

The candle is unusual. It is done like this: pour paraffin on the outside of a glass test tube so that it looks like a candle. Close the test tube with a metal cap with a hole. through which the wick will pass. Pour some alcohol into the test tube so that it saturates the wick. After this, also fill the cap with paraffin so that only the wick peeks out. The "candle" is ready.

An ordinary glass rod will serve as a magic wand, on the end of which you will collect a very small mixture of potassium permanganate and sulfuric acid. Prepare the mixture in very small quantities, necessary only for one experiment. Do not touch the mixture with your hands. Touch the wick with a stick and a flame will immediately flare up at the end.

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 ... >>

To predict a heart attack, droplets of blood stop 08.04.2012

Scientists from the Institute of Translational Medicine. E. Scripps began testing a new test that can detect an imminent heart attack. A simple test predicts a possible heart attack using a sample of blood and cells that slough off damaged blood vessel walls.

This invention closes a major gap in the diagnosis of cardiac diseases. Today, doctors can detect a heart attack only when it has already happened. Yet each year, tens of thousands of patients, even after stress tests in the doctor's office, face the devastating effects of a life-threatening heart attack a few weeks later.

A heart attack occurs after an atherosclerotic plaque ruptures in an artery. The result is a clot that blocks blood flow to the heart. Thus, damage to the tissues of the heart occurs, often life-threatening for the patient, especially when it comes to rupture of cholesterol plaques. In the latter case, the disease is often asymptomatic, and a heart attack occurs unexpectedly. The new test solves this problem, i.e. know in advance about the increased risk of damage to heart tissue. Now the doctor will be able to find out about damage to the endothelium (a layer of cells on the inner surface of blood vessels) even before the formation of a dangerous blood clot and prevent a heart attack or stroke.

Unfortunately, the new test does not yet allow you to accurately determine when exactly an attack will occur: in a day, two or a week. Therefore, people at high risk will have to be tested regularly. Currently, scientists are discussing the possibility of creating a portable device that can quickly detect circulating endothelial cells that indicate damage to blood vessels.
