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 Thought controls the genes
20.11.2014
Imagine that you have a cold: you sneeze, cough, measure the temperature every minute. And now you think that it would be good to increase the activity of the immune system so that it quickly expels the infection from you. And suddenly, in response to such thoughts, your immunity really activates: the synthesis of interferon increases, immune cells begin to actively hunt for the pathogen, etc.
Sounds fantastic, but that's exactly what Martin Fussenegger and his colleagues at the ETH Zurich (Switzerland) managed to do - the researchers created a device that turns brain impulses into genetic regulatory signals. Moreover, the transfer of thoughts was carried out between a person and a mouse, that is, a person thought about something, and physiological changes occurred in an animal.
However, if you disassemble the device described in Nature Communications into its component parts, it turns out that there is nothing super-fantastic in it - the authors of the work in their experiments simply combined well-known and well-developed biotechnological discoveries. Firstly, it is a brain-computer interface (BCI), and secondly, optogenetic methods. With the help of a brain-computer interface, it was possible to turn the EEG rhythms of the brain into some kind of signal directed outward, intended for an external device. An EEG sensor was attached to a person's forehead, and the person was asked to complete one of three tasks: play a computer game for ten minutes; try to turn on the LED implanted in the mouse by force of will; finally, he could just rest, daydream about anything, or meditate.
In all three cases, the brain produced rather special signals that were transmitted via Bluetooth to a device implanted in the mouse. The animal ran freely on the surface generating an electromagnetic field, and depending on the human mental state, a certain impulse went from the surface to the implant-receiver.
The implant itself was a cell with cells synthesizing a certain protein that could come out of the implant and activate the synthesis of interferon. The cells were optogenetically modified, that is, they carried a photoprotein that reacts to a light pulse of a certain wavelength. The light pulse turned on the photoreceptor, and it already gave a signal to the synthesis of a protein, including the synthesis of interferon in mice.
That is, the mental signal literally turned on the light in the implant, equipped with a special LED. Moreover, in one of the variants of the experiment, as mentioned above, a person could monitor the state of the implant himself and purposefully turn it on with a neuropsychological effort.
I must say that neurocomputer interfaces that transmit brain signals to various devices are actively used in a variety of projects (and most actively, of course, in the development of prostheses that can be controlled by the power of thought). However, to send a signal from them to the cellular-molecular apparatus in order to activate some genes and affect physiology - there have been no such precedents so far.
It is easy to imagine such a device that, for example, would relieve a person from chronic pain in response to incipient pain signals, or stop an epileptic seizure at its first signs. True, before that, many experiments still have to be done to make the technology compatible with the human body.
