How durable are atoms?

Atoms are practically eternal. According to some estimates, the duration of their existence, expressed in years, is represented by one followed by 35 zeros - one hundred trillion sextillions.

In which English city is every elected mayor publicly weighed, and why?

In the English town of High Wycombe, each elected mayor is weighed in on the town square. This tradition dates back to 1678, when the residents decided to put an end to the behavior of mayors who stole money from the treasury, after which they got fat from a satisfying life. After a year of service, the mayor is weighed again, and the herald shouts "More!" or "Not added!". In the old days, the townspeople, having heard about weight gain, could boo the mayor and throw rotten eggs, now this part of the tradition has been canceled.

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. ... >>

Created a biodegradable transistor based on proteins 24.03.2012

A team of scientists using advanced methods from various fields of science created a transistor based on proteins present in the human body. According to the calculations of developers from Tel Aviv University, the new technology can become the basis for various flexible electronic nanodevices with the ability to biodegrade.

One of the problems with using silicon as a semiconductor is that the silicon transistor must be built from the top down. Manufacturers take a sheet of silicon and actually "cut" a microchip out of it. This method limits the possibilities of transistors, especially in terms of miniaturization and flexibility. Thus, silicon is rapidly becoming obsolete, and recycling of obsolete electronics is expensive and pollutes the environment.

Scientists used the latest advances in chemistry and biology to create the perfect transistor. They studied various combinations of blood, milk and mucus proteins in order to create self-organizing molecules that form semiconductor films at the nanoscale. In the case of blood proteins, for example, it was possible to obtain films with a thickness of about 4 nanometers, which is 4,5 times thinner than using modern silicon technologies. With the help of three different types of proteins, you can create a complete electronic circuit with unique capabilities. For example, a blood protein has the ability to absorb oxygen, which allows the production of semiconductors from certain chemicals.

In turn, milk proteins form fibers that form the structure of transistors, while mucosal proteins have the ability to hold red, green, and blue fluorescent dyes. Thus, the circuit can emit the white light required for advanced optics. In general, the natural features of each protein give researchers the opportunity to control the properties of an organic transistor: change conductivity, memory, fluorescence, etc.

Protein-based transistors could revolutionize electronics. They are ideal for small, flexible devices because, unlike silicon, they do not break. This will make it possible to launch a new generation of flexible screens, mobile phones, biosensors, microprocessors, and so on. At the same time, this electronics will be biodegradable and will not harm the environment.
