Where and when did the ribbon (package) appear on cigars?

A ribbon (package) on cigars appeared in Cuba during the colonization of the island by Spain, when cigar smoking became fashionable among noble ladies. In order not to stain their fingers with a yellow coating of nicotine, they began to hold a cigar, wrapping it with a narrow paper ribbon.

 Random interesting fact from the Great Encyclopedia:

What drug was originally marketed as a cough medicine for children?

Many well-known drugs were originally promoted as medicines. For example, heroin was introduced to the market in 1898 by the German company Bayer AG as a cough medicine for children. Although after 15 years its production in this status was stopped, even before 1971 heroin could be bought in German pharmacies. The medical history of cocaine is even richer: numerous experiments in the second half of the 19th century gave rise to scientists recommending it for anesthesia and increasing endurance. Sigmund Freud, after testing the properties of cocaine on himself, promoted it as a cure for depression, sexual disorders, syphilis, and alcoholism. Freud claimed that cocaine was not addictive, but this was subsequently refuted, and cocaine was gradually banned in all countries.

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. ... >>

Graphene and starch hydrogel coatings for brain implants 03.12.2018

Hydrogels are polymeric networks capable of holding large amounts of liquid when they are in water without changing their size. With the addition of new components, hydrogels can acquire certain properties: for example, electrical conductivity. Their application is diverse: from gardening to medicine.

In this case, we are talking about medical use. The hydrogel is coated with neural interfaces, the components responsible for the electrical connection in brain implants that interact with the nervous system by stimulating neurons with electrical impulses. The polymer network allows neural interfaces - usually rigid - to interact more gently with brain tissue.

To provide their hydrogel with electrical conductivity, scientists from the University of the Basque Country Krom used graphene. This material provides electrical properties that are very suitable for a hydrogel. He has one drawback: he is not easily stabilized in water. Therefore, scientists used sage extracts to make graphene stable in the aquatic environment. These extracts also make the hydrogel even more suitable for medical use, as they have antimicrobial and anti-inflammatory properties.

In addition, the researchers chose for another hydrogel a biopolymer that has not yet been used for such structures: starch. The development is also unique in that scientists used the click chemistry method to obtain a hydrogel. This is a strategy that has attracted the attention of the scientific community in recent years because, unlike other synthesis methods, click chemistry does not use catalysts in reactions. Chemical substances are obtained by connecting individual small elements together.

The method does not require a large amount of energy to create substances and does not leave by-products.
