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. ... >>

Heat controlled microbe 25.04.2012

Scientists at the University of Georgia have created a temperature-controlled microbe. The new microorganism could be an efficient means of producing complex chemicals from simple starting materials.

Initially, scientists took the microbe Pyrococcus furiosus, which lives in hot marine sediments and actively reproduces at temperatures around 100 degrees Celsius. This microorganism is an archaea, a single-celled prokaryote that is similar to a bacterium, but has significant differences at the molecular level and is able to perform processes that bacteria cannot.

Nowadays, many manufacturing processes depend on microorganisms. However, the production activity of bacteria is very difficult to control, especially to switch them from one activity to another.

American scientists have found a way to control heat-loving microbes using a temperature switch. Simply put, at high temperatures, the microbe produces one product, and at low temperatures, another or not at all. This greatly simplifies the use of microorganisms as miniature plants for the production of useful substances such as biofuels. Also, for the first time, scientists have managed to make changes to the genome of a hyperthermophilic bacterium, which opens up new opportunities in the creation of genetically modified microorganisms with unique functions.

Like other hyperthermophilic bacteria, Pyrococcus furiosus can function at high temperatures, which is very useful in many industrial processes in the chemical industry. However, not all substances can be produced under such conditions - some enzymes can only work at low temperatures.

To solve this problem, scientists took a specific gene from the bacterium Caldicellulosiruptor bescii, which lives in cooler conditions (72 degrees Celsius), and placed it in the genome of Pyrococcus furiosus. As a result, at high temperatures, Pyrococcus furiosus functions as usual, and when the temperature drops, it begins to produce another, unusual product, lactate dehydrogenase.
