How are virgins and virgins different from their peers?

It turned out that adolescent virgins, both boys and girls, as a rule, turn out to be either much smarter or much dumber than their peers. The largest number of young people of both sexes lose their virginity at the age of 19.

 Random interesting fact from the Great Encyclopedia:

Why is deodorant so much less popular in East Asia than in Europe?

There are two versions of the ABCC11 gene that are common in the human population. Those of us who have at least one of two copies of the dominant version of the gene produce liquid earwax, while those of us with two copies of the recessive variant have solid earwax. Also, this gene is responsible for the production of proteins that remove sweat from the pores in the armpits, attracting odor-causing bacteria. People with hard earwax don't sweat like that, so they don't have odor problems and don't need to use deodorant. This category includes the majority of the population of East Asia, but very few Europeans.

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 ... >>

Microphones inspired by insects 09.05.2023

What can an insect hear? Oddly enough, quite a lot. Although they are small and simple, their auditory systems are very effective. For example, with a membrane only 2 millimeters across, the Desert Locust can decompose frequencies comparable to human capabilities. By understanding how insects perceive sound and using 3D printing technology to create special materials, miniature microphones inspired by biotechnology can be designed.

Andrew Reid from the University of Strathclyde in the UK presented his work on microphones that can autonomously collect acoustic data with low power consumption. His presentation "Unnatural Hearing - 3D Printing of Functional Polymers as a Pathway to Biotechnology-Inspired Microphone Design" took place on Wednesday, May 10, as part of the 184th Acoustic Society of America meeting.

"Insect ears are ideal templates for reducing energy and data costs, reducing the size of sensors and eliminating data processing," Reid said.

Reid's team draws inspiration from insect ears in a variety of ways. At the chemical and structural levels, researchers are using 3D printing technology to fabricate special materials that mimic insect membranes. These synthetic membranes are highly sensitive and effective as acoustic sensors. Without 3D printing, traditional silicon microphones lack flexibility and customization.

"In the images, our microphone looks like any other microphone. The mechanical element is a simple diaphragm, perhaps a slightly unusual ellipsoid or rectangular shape," said Reid. "Interesting details occur at the microscale with small variations in thickness and porosity, and at the nanoscale with variations in material properties such as ductility and material density."

More than just material, the entire data collection process is inspired by biological systems. Unlike traditional microphones that collect a range of information, these microphones are designed to detect a specific signal. This simplified process is similar to how nerve endings detect and transmit signals. The specialization of the sensor allows it to quickly recognize triggers without consuming much power or requiring supervision.

Bio-based sensors, with their small size, self-contained function, and low power consumption, are ideal for hazardous or hard-to-reach applications, including locations embedded in structures or inside the human body.
