Of course it's attractive. Otherwise, the paper dancers in our theater would not have danced. You can do some more experiments with electric attraction.

The source of electricity for these experiments is a stick made of sealing wax, ebonite, and best of all of plexiglass, rubbed with a dry woolen cloth. By the way, rulers, squares, cigarette cases, pens (not self-writing, but simple), even ink devices are often made from transparent plexiglass (white or dyed in mass). All these things are well suited for our experiments.

Electricity attracts

Experience first. Place the egg in a glass and balance the ruler on it. Bring a rubbed stick to the end of the ruler. The ruler will follow the stick like a compass needle!

Second experience. Cut a sheet of tissue paper into strips, but not completely, but like a comb and wrap the whole side around the fountain pen. It will turn out like a brush. Insert the pen with the other end into some kind of stand - the brush will sag. Bring a rubbed stick - strips of tissue paper will stir and reach for it.

Electricity attracts

Experience the third. Let a thin stream of water out of the tap. Bring an electrified wand to it.

The trickle will deviate towards the stick! This will be more noticeable the farther from the body you hold the wand. With a good piece of plexiglass, you can even get water to flow past the sink!

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. ... >>

Non-bitter chicory bred 11.08.2021

Researchers at Wageningen University have used new breeding methods to develop a variety of chicory that no longer contains bitter compounds.

Chicory is a beautiful plant with blue flowers, but the interesting part of it is in the ground: chicory roots are a source of inulin, a natural sweetener used in bread and dairy products, and as dietary fiber for healthy bowel function.

"Inulin has a positive effect on the health of the digestive system. Usually, inulin needs to be separated from bitter compounds (which are also found in the root) as they cause a bitter taste. With new breeding methods such as CRISPR-Cas, we were able to develop a plant that is no longer contains bitterness. This will lead to less expensive, easier and more environmentally friendly processing, as well as a wider use of inulin. Now we know which genes are involved in the production of bitter compounds, so we can also change the level of bitterness in witloof, "the scientists said.

The new CRISPR-Cas method specifically targets chicory DNA, which is responsible for certain desirable or undesirable plant characteristics.

"A technique called genome editing makes small changes to the DNA. So the grown chicory contains only its own DNA. We turned off four genes responsible for bitter substances. To do this, we took cells from a leaf, processed them with technology, and then allowed them grow back (in the greenhouse). Using this method, breeding is much faster," explained KeyGene spokesman Paul Bundock.

Within the framework of the European CHIC project, researchers and enterprises are also working on the development of the specific bitter chicory compounds (terpenes) themselves. These compounds can serve as anti-inflammatory agents and/or cancer drugs.

"Bitter compounds protect plants from fungi and bacteria. In the project, we were able to demonstrate anti-inflammatory activity. Previous studies have shown that bitter compounds in chicory have antihelminthic effects in sheep," said Sensus corporate development manager Matthew de Roode.
