The smell of a partner improves sleep

04.03.2020

The scent of a romantic partner may improve sleep, a new study from the University of British Columbia suggests. Researchers found that study participants who were exposed to their partner's body odor throughout the night had better sleep quality, even if their partner wasn't physically present.

"We saw an effect commensurate with taking supplements of melatonin, the 'sleep hormone' often used as a mild sleep aid," says Marlies Hofer, lead author of the study. The researchers analyzed data from 155 participants who were given two identical T-shirts to use as pillowcases. One of them was previously worn by their romantic partner.

To capture body odor on T-shirts, participants' partners were given a clean T-shirt to wear for 24 hours. They were required to refrain from using deodorants and scented body products, smoking, exercising, and eating certain foods that can affect body odor. The T-shirts were then frozen to preserve the flavor.

The researchers measured participants' sleep quality with a sleep watch that tracked their movements throughout the night. Volunteers reported feeling more rested that night when they slept with their partner's scent. Objective sleep data showed that their sleep actually improved. "One of the most surprising findings is that the scent of a romantic partner improves the quality of sleep on a subconscious level," says Francis Chen, senior author of the study. The researchers highlight that the physical presence of a partner is associated with positive health outcomes, which in turn leads to better sleep. The scent of a partner may have similar benefits.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 ... >>

A new way to repel ice 20.03.2020

Ice is one of the most problematic factors in many industrial, service and transportation segments, causing disasters and problems of various kinds and complexity. The development of new materials for ice rejection is becoming a real hot topic for many research teams, and the chemical engineering team at the University of Virginia is no exception. Today, scientists presented their new experimental material, which has a very high degree of ice repulsion, due to which it has the potential to be used in a variety of directions and segments.

The specialists managed to create this material on the basis of a rather effective and popular theory in physics called "disaster localization". According to this theory, changing the physical and chemical properties of certain areas of the material is a much more efficient and useful approach than creating the entire material with the desired properties. The result of the research was a special film made of silicone polymer, which demonstrates a high degree of ice repulsion due to the formation of localized areas of so-called "cracks" on the surface.

These cracks are not permanent and do not lead to degradation of the material, but on the contrary, enhance its properties in certain areas, creating irregularities, due to the exfoliation of ice layers - as a result, the material repels the vast majority of ice and ice cover, thereby effectively protecting others. materials. And thanks to its easy application to other materials, it can be used in almost any suitable case.

At the moment, specialists continue to work on improving and stabilizing their material - as they are interested in applying this material on a longer-term basis in more complex aspects and directions. It remains to wait for new news regarding the material, which will surely occupy its niche.
