Poultices for David

02.08.2005

Michelangelo di Lodovico di Lionardo di Buonarroti Simoni, better known by his first name, created his famous statue of David by order of Florence in 1504.

More than 500 years ago, a marble figure 516 centimeters high and weighing 5,5 tons appeared on Signoria Square. In subsequent centuries, David often suffered from the forces of the elements and human aggression: lightning struck the statue, in 1527, during a popular uprising, her left arm was broken, hooligans broke off her toes “for memory”. In 1873, the masterpiece was transferred to the gallery of the Academy, and a copy was placed on the square.

The original from time to time was subjected to "cleaning" and polishing with acid solutions, which did not do him any good. In 2003, they decided to clean David from centuries of dust and dirt, which continued to accumulate in the gallery.

As a result of long disputes, it was decided to abandon the chemicals and, after vacuuming, wash the statue with distilled water and wipe it with paper towels. On the most polluted places, "poultices" of cellulose with white clay were applied for 15 minutes, which absorbed the dirt. Along the way, they made accurate measurements of the statue and made an x-ray of the ankles. Cracks were found in them, so that David could collapse in an earthquake.

From now on, the surface of the marble is free from contamination, and from now on, dust will be collected from it every one and a half months.

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Playing Tetris will get rid of painful memories 11.05.2012

For a long time, post-traumatic stress disorder (PTSD) was only a problem for survivors of violence, car accidents, natural disasters, trauma, and so on. However, during the wars in Iraq and Afghanistan, there were so many patients with PTSD (at least 25% of returned soldiers) that the Pentagon had to pay attention to this and allocate a lot of money to solve this problem.

Unfortunately, behavioral changes caused by severe stress have proven difficult to treat. It is especially difficult to find a simple and effective therapy immediately after a psychological trauma. However, the study, conducted by Oxford researchers, offers a completely new approach to treating the symptoms of post-traumatic stress.

It turns out that the old Tetris game can help. Scientists have found that playing Tetris in a specific way loads the brain and prevents it from fixing traumatic memories. Thus, if you immediately sit down to play Tetris after a hard experience or a terrible incident, then the game will prevent the recent experience from turning into vivid lasting memories.

During the experiment, psychologists invited 60 volunteers to watch videos with scenes of injury or death. After 30 minutes of watching, the group was divided into three parts: the first sat down to play Tetris, the second took part in a small 10-minute quiz, and the third just sat and did nothing. The participants were then allowed to go home and asked to record all their memories of the scary video for a week.

As a result, it turned out that people who played Tetris had an average of 2 memories of a scary video, while others had 4-5.

Of course, weeks of monitoring and video cannot be compared to a full recovery after a horrific experience of combat or other events directly related to the death and injury of people. However, the results of 'Tetris-therapy' are encouraging, and scientists are going to continue research in the field - directly in the field of combat operations. Apparently, the experiments will be carried out with soldiers who have just returned from a serious alteration.
