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. ... >>

Worms against aging 06.01.2020

Scientists from the MDI Laboratory, together with scientists from the Buck Institute for Research on Aging and the University of Nanjing, have discovered synergistic cellular mechanisms that increase lifespan by six times in C. elegans nematodes, which are often used as model organisms in aging research.

Such a life expectancy in worms corresponds to a human life expectancy of 400-500 years.

The study is based on the discovery of two major pathways that drive aging C. elegans, which are popular model organisms in aging research due to their many genes in common with humans, and because of their short lifespan of three to four weeks, allowing researchers to quickly assess the impact of both genetic and environmental factors on life expectancy.

The study used organisms with a double mutation: the insulin signaling pathways and TOR complexes were changed. Altering insulin signaling alone gives a 100% increase in lifespan in nematodes. A separate change to TOR is 30 percent. It was logical to assume that their combined change would give a 130% increase, but instead life expectancy increased by 500%.

The discovery of a synergistic effect in the future will allow the use of combination therapy to prolong life in the same way that various combination therapies are currently used to treat cancer or AIDS. It could also explain why scientists couldn't find a single gene responsible for longevity.
