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. ... >>

Random news from the Archive When boarding a flight, show a working gadget 08.07.2014 Those who regularly travel around the world should familiarize themselves with the new order of the American Transportation Security Administration (TSA). Now, in order to get on board an aircraft bound for the United States, you will have to demonstrate the functionality of your tablet, smartphone, laptop, or any other mobile device. According to them, the TSA leadership took forced measures when passengers passed control for subsequent boarding the plane. Now one of the prerequisites for getting on the flight will be a demonstration of the possibility of switching on and operating electronics. If the battery is accidentally discharged and the device does not turn on in any way, then serious troubles can await you, up to and including removal from the flight. This wording of the new requirements for passengers, at first glance, although it sounds rather strange, but has real reasons. The rules introduced by the TSA are designed to help detect potentially dangerous electronics, in the case of which a terrorist passenger could build an explosive device to carry out a terrorist attack. U.S. national security intelligence has revealed that radical terrorist groups from Yemen and Syria may use the practice of disguising miniature bombs as conventional mobile devices, allowing them to be carried on planes without undue suspicion. Checking for inclusion will make it possible to make sure that at least the main part of the original components is present inside the smartphone / tablet / laptop, and not explosives. The rule should include international airports that provide air transportation to the United States. True, at this stage, representatives of the American intelligence services did not specify in which countries and for how long additional precautionary measures will be introduced. In the event that your device turned out to be faulty and you cannot demonstrate its operability, it will be seized for storage by the airport staff. You, as the owner of a potentially dangerous device, the security service has every right to refuse to board the plane.
