Focus Description:

Insert a cigarette into your mouth. However, it turns out that you took it with the filter forward. Turn it over, but the cigarette will again be the filter forward (Fig. a). And do this several times.

Focus secret:

The secret of the trick is in a fake cigarette made from a white paper tube. At both ends, half of the filter is glued to it (Fig. b).

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 ... >>

The electronic patch will inform about the health of the patient 25.08.2017

Until recently, medical system sensors placed on a patient's body to collect health data were bulky and uncomfortable to wear. The use of new technologies has allowed scientists to create sensors the size of a coin and as thick as adhesive tape.

The smart patch, created by Kyung-In Jang, Professor of Robotics at the Korea Institute of Science and Technology (DGIST) and John A. Rogers from Northwestern University (USA), consists of a silicone body containing " 50 components connected by a network of 250 tiny wire spools." The silicone adheres tightly to the body and the sensor transmits data on "movement and breathing, as well as the electrical activity of the heart, muscles, eyes and brain."

Unlike flat gauges, tiny wire coils can stretch and compress like a spring without breaking their integrity. Coils and sensor components are configured in a web-like system that provides "uniform and extreme levels of stretch and flexibility in any direction". This also provides a more compact arrangement of components, minimizing the size of the device.

The sensor can be connected to a wireless network, which means that it can be placed almost anywhere on the body. In the future, it is planned to use this system in robots when a more flexible connector is required.

Dong said he intends to continue further research into the development of electronic patches that will provide access to interactive treatment systems and telemedicine services for patients in areas that are difficult to access medical services, such as villages in the mountains.
