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 ... >>
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 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. ... >>

Aerosol with nanobots
03.08.2018
Scientists from the Massachusetts Institute of Technology have created the world's first aerosol containing nanobots. The discovery could radically change the development of robotics. These nanobots can do almost everything from detecting dangerous leaks in pipes to diagnosing health problems.
Each sensor in an aerosol spray consists of two parts. The first is a colloid, a tiny insoluble particle or molecule. Colloids are so small that they can float in air or water forever - the force of the particles colliding around them is greater than the force of gravity.
The second part is a complex circuit consisting of a chemical detector built from a two-dimensional material like graphene. When this sensor encounters a certain chemical in the environment, its ability to conduct electricity is enhanced. The circuit also features a photodiode, a device capable of converting light around it into electrical current. It provides the system with the energy needed to collect data and the nanobot's memory.
The researchers grafted the circuit onto colloids, thus giving the latter the ability to travel in unique environments. After combining, the scientists gave the nanobots the form of a spray, that is, they can now be sprayed. This delivery method would not be possible without colloids. "The circuits couldn't exist without a substrate," says study lead author Michael Strano. "We had to embed the circuits into the particles to give the system strength and also make it big enough for the bots to travel with the flow."
What are these nanobots for? Scientists have demonstrated several ways to use them. For example, they designed sensors to detect poisonous ammonia and tested this ability in a section of pipe. They sprayed the sensors from one end and collected them from the other with gauze. By analyzing the information in the diagrams, they were able to tell if the sensors had come into contact with ammonia.
In the real world, the technology could save inspectors the trouble of inspecting the entire pipe from the outside by simply spraying nanobot aerosols down there.
The same technology can help diagnose diseases in the human body by traveling through the digestive tract, collecting information and delivering it to doctors.
