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. ... >>

Creation of new plants without DNA insertion 29.12.2015

The brilliant idea of ​​gene transplantation has run into so much resistance from society that breeders are forced to look for workarounds to quickly create plants with improved properties. One of them is genome editing without the use of foreign DNA. Researchers from the South Korean Institute of Basic Science, led by Jin-Soo Kim, tested this method on lettuce, tobacco, and rice cells.

Edited with CRISPR/Cas9 molecular scissors. Such a design cuts the plant's DNA in a precisely chosen place, and then the cell closes the damage on its own, thus withdrawing the marked gene from circulation. That is, nothing is inserted into the genome - they only turn off the plant's own gene.

According to the authors of the work, the procedure practically does not differ from the usual mutagenesis that occurs in nature, except that it is not a random gene that is damaged, but a pre-selected one. Experiments with edited cells showed that the operation was successful: there was no mosaic of genes in the samples of proliferating cells.

From the seeds obtained, it was possible to grow edited plants in almost half of the cases and in the second generation. Since they do not contain foreign DNA, they are not subject to EU restrictions. Moreover, the technique is relatively simple, and it can be used in small seed farms, which removes a serious problem - dependence on a monopoly producer of transgenic seeds.

True, genome editing may not be so harmless and without any foreign DNA. For example, in potatoes, poisonous berries accompany completely edible tubers. They have one genome, it's all about the regulation of gene activity. And if you inaccurately edit this very regulator, then ...
