Did you know?

Are there seas on the Moon?

Yes, at least in name. These are relatively flat flat areas of the lunar surface, on which, of course, there is no water. Astronomers of the Middle Ages believed that large dark areas on the Moon were seas similar to those on Earth, and gave them the appropriate names (Sea of ​​Tranquility, Ocean of Storms, etc.), which have survived to this day.

Why doesn't Spielberg come to film the last scenes of the films he directs?

Steven Spielberg didn't show up to the director's chair when the final scene of Jaws where the shark explodes was being filmed - he was sure the crew had conspired and were planning to throw him into the water after the "cut" command. Since then, Spielberg has made it a tradition not to show up for the final scene of every movie he directs.

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 ... >>

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. ... >>

Nanoparticles will stop old age 19.10.2012

A team of Spanish scientists have developed "smart" nanoparticles that could potentially be used to combat the symptoms of aging.
Specially designed nanoparticles can selectively release drugs in old human cells. The potential of this technology is very large: it can cope with such ailments as cancer, cell degeneration, Alzheimer's, Parkinson's, etc.

"Smart" mesoporous silicon nanoparticles contain galactooligosaccharides that prevent drug release in young healthy cells and release it in aging cells. In other words, for the first time, scientists have been able to create a "guidance system" that directs the drug precisely to the degenerative cells that cause various diseases.

During the experiments, the researchers have already evaluated the effectiveness of new nanoparticles. In particular, it was possible to influence old cells that secrete beta-galactosidase, an enzyme that is characteristic of aging cells. Scientists have developed special nanoparticles that "target" this enzyme, thus detecting old cells and destroying them, opening the way for self-rejuvenation of the body.

Cellular aging is a physiological process that eliminates too old and damaged cells that do more harm than good to the body. When a person is young, the mechanisms of aging prevent many diseases, such as the development of tumors. The problem is that with age, there are more and more aging cells - they accumulate in organs and tissues, disrupting the normal functioning of the body. The discovery of Spanish scientists shows that medicine can use a targeted effect on old cells: treat them or destroy them.
