What famous child character first looked like a white dog?

Murzilka was not always a yellow creature in a beret and scarf. Back in the late 19th century, the writer Anna Khvolson released a series of stories about little forest men based on the poems of the Canadian Palmer Hawks. The main character was named Murzilka, and in the illustrations he was depicted in a tailcoat, with a cane and a monocle. When the Murzilka magazine was founded in 1924, our hero became a small white dog with the owner, the boy Petya. But neither the readers nor the authors of the magazine particularly liked this dog, and in 1937 the artist Kanevsky came up with the classic image of Murzilka, familiar to us.

Random interesting fact from the Great Encyclopedia:

Why is it warmer in summer than in winter?

Isn't it strange: when winter reigns in the northern hemisphere, the Earth is closer to the Sun by 4 km than when it is summer there. The fact is that in this case, the weather is determined not by the distance from our planet to the Sun, but by the tilt of the earth's axis in relation to the plane of the earth's orbit. The angle of this inclination is 500 degrees.

The earth revolves around the sun in such a way that its axis is always directed towards the North Star. Therefore, for one half of the year, the North Pole of the earth leans towards the Sun, and for the rest it deviates from it. In the first case, summer reigns in the Northern Hemisphere, in the second - winter. In the South, of course, the opposite is true.

The weather in a particular region of the earth depends on the angle at which the sun's rays fall on a given area of the earth's surface. In winter, the low sun illuminates the earth with gliding rays, and in summer they fall vertically. Glancing rays heat the Earth's surface less for two reasons.

First, because the same amount of heat is distributed over a larger area in winter than in summer. Secondly, in this case, the rays pass through a thicker layer of air in the Earth's atmosphere, which leads to large losses of their thermal energy. The climate is determined not only by the amount of heat entering a particular part of the Earth's surface from the Sun, but also by other factors.

For example, in the expanses of the seas and in the areas adjacent to them, temperature changes with the change of seasons are not so great. On the contrary, in the depths of the continents, the difference between the temperature in winter and summer is much more significant. This is due to the fact that the earth cools and heats up much faster than water.

Another factor that affects the weather is the difference in altitude above sea level. As altitude increases, air density decreases, and hence its ability to retain heat. As a result, the climate in the mountainous regions is much colder than in the plains.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Living synthetic cells created 24.09.2022

Researchers at the University of Bristol in the UK have taken a big step forward in the field of synthetic biology. Scientists have developed a system that performs several key functions of a living cell, including energy generation and gene expression.

Scientists have previously focused on getting artificial cells to perform a single function, such as gene expression, enzyme catalysis, or ribozyme activity. If scientists unlock the secret to individually creating and programming artificial cells that can more closely mimic life, it could open up a myriad of possibilities in everything from manufacturing to medicine.

While some engineers are focusing on redesigning the cells themselves, others are looking for ways to cut existing cells down to fragments that can then be redesigned into something relatively new.

To accomplish this latest bottom-up bioengineering feat, the researchers used two bacterial colonies, Escherichia coli and Pseudomonas aeruginosa. These two bacteria were mixed with empty microdroplets in a viscous liquid. One population was captured inside the drops, and the other was captured on the surface of the drops.

The scientists then cut open the membranes of the bacteria by immersing the colonies in lysozyme (an enzyme) and melittin (a polypeptide derived from bee venom). The bacteria spit out their contents, which were captured by the droplets to create membrane-covered protocells.

Scientists have demonstrated that cells are capable of complex processing, such as the production of the energy storage molecule ATP through glycolysis, and the transcription and translation of genes.

"Our approach to the assembly of living material makes it possible to create symbiotic living / synthetic cell constructs from the bottom up. For example, using engineered bacteria, it will be possible to produce complex modules for development in the diagnostic and therapeutic areas of synthetic biology, as well as in biomanufacturing and biotechnology in general," - noted the first author, chemist Can Xu.

In the future, this kind of synthetic cell technology could be used to improve the production of ethanol for the biofuel and food industries. In addition, such artificial cells can be programmed for photosynthesis, like purple bacteria, or for generating energy from chemicals, like sulfate-reducing bacteria do.
