Why was Chewbacca accompanied in the forests of California by assistants in brightly colored suits?

Scenes from the sixth episode of Star Wars were filmed on the moon Endor in the forests of California. When filming shots where Chewbacca acts alone, Peter Mayhew, who plays him, was accompanied by several assistants in brightly colored costumes. Otherwise, according to the director's fears, local hunters could mistake Chewbacca for Bigfoot and shoot him.

What is the nitrogen cycle?

All life on earth requires nitrogen in a usable form. It is just as important for plants and animals as it is for humans. Nitrogen is a component of protein, which is a building material for the human body. Without this substance, no one would be able to grow or repair damaged tissue.

While oxygen makes up 21% of the air we breathe, it contains 78% nitrogen. Over one square kilometer of the earth's surface is approximately 7 tons of nitrogen. It is a colorless, odorless, tasteless gas that is slightly soluble in water. It may seem that since nitrogen is everywhere in the surrounding air, it is very easy for a living being to obtain it. But man cannot consume pure nitrogen. When inhaled, it absorbs oxygen. Therefore, nitrogen is useful only when, in combination with other substances, it forms compounds.

In nature, there are only a few plants that can absorb pure nitrogen from the air. These include legumes: beans, peas and clover. But all plants are able to use simple nitrogen compounds from the soil in which they grow. Therefore, in nature, there is a nitrogen cycle that allows you to support the life of plants and animals. Plants take simple nitrogen compounds from the soil and combine them with carbon to make protein. Animals get nitrogen by eating plants.

Nitrogen returns to the earth in the waste guide. Certain bacteria convert these wastes back into simple nitrogen compounds, and plants can use them again. Thus the cycle ends. Nitrogen reserves are also replenished by bacteria, which take nitrogen from the air and accumulate it in the soil.

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. ... >>

A new protein that controls the red color of strawberries identified 12.05.2023

A research team from the University of Córdoba has described a new transcription factor that regulates the production of anthocyanins when strawberries ripen, responsible for giving them a red hue.

Strawberry is a fruit that stands out for its color, aroma, flavor and texture. These aspects, known as organoleptic properties that determine their quality and the benefits of potential consumers, as well as insects that disperse seeds, contributing to the further growth of future plants, appear during the ripening of strawberries.

The Plant Biotechnology and Pharmacognosy Research Group at the University of Córdoba, led by Juan Muñoz Blanca, has been studying the genetic regulation of strawberry ripening for several years and has now gone one step further in their understanding of this key process by discovering a new protein involved in controlling the red color of the fruit. It is known as a transcription factor protein (FaMYB123) responsible for activating or inhibiting the expression of other genes.

This transcription factor is mainly responsible for the production of anthocyanins, the pigments that, in the case of strawberries, give them their characteristic red color.

To test this, they created a transgenic strawberry plant in which they downregulated the expression of the transcription factor FaMYB123, and they saw that the amount of anthocyanins was suppressed in these transgenic plants more than compared to normal fruit. That is, without the described transcription factor, strawberries do not show all their red color.

However, this is not done by a single protein, since transcription factors do not work in isolation, but rather in combination. In this case, the research team found that FaMYB123 is associated with another previously known factor (FabHLH3) also associated with strawberry pigmentation. The interaction between them contributes to an increase in the production of anthocyanins during their maturation.

In short, the study provides new knowledge about strawberry ripening control. Knowing which piece of the puzzle controls each part of the maturation process - in this case the color red - allows us to genetically manipulate it or use it as a tool in the maturation process. Breeding programs in which different varieties are combined to create new ones.
