Did you know?

A drop of water in a very hot frying pan "floats" on a layer of steam, which serves as a kind of heat-insulating layer.

In addition, the drop at the same time, under the action of surface tension forces, rolls up into a ball, the zone of its contact (and hence the heat exchange) with the hot metal is greatly reduced.

Where is the center of mass of the Earth-Moon system?

The center of mass of the Earth-Moon system, the so-called barycenter, is located at a distance of 4672 kilometers from the center of the Earth towards the Moon, that is, at a depth of approximately 1700 kilometers below the Earth's surface.

Strictly speaking, it is not the Earth that moves in an elliptical orbit around the Sun, but the barycenter, while the Earth and the Moon rotate relative to the barycenter, making a complete revolution per lunar month.

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.

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. ... >>

Heavy-duty shell helmet material 11.06.2017

Mollusk shells are extremely durable shells that allow animals to withstand the "blows" of tides and storms, as well as fend off predators. Researchers from the Massachusetts Institute of Technology decided to study the structure of the shell of mollusks in more detail, and as a result they created a super-strong material that can be used in industry in the future.

A team of researchers developed 3D printing technology that allowed them to mimic the structure of a shell so they could study it more closely in the lab. They took the shells of molluscs of the strombid family as a basis. It turned out that they have a complex three-level structure with a zigzag matrix. Due to this, even if a small crack forms on the shell of the mollusk, it does not grow, as it has to "go through the labyrinth" of layers.

To better understand the formation of cracks in the shells, the researchers 3D-printed samples that resemble the shell of mollusks in structure and conducted a series of tests.

The results obtained during the tests showed that the structure of the shell prevents cracks by 85% better than most durable materials, such as those made of fiber composite.

The researchers believe their technology could be used to make helmets, protective clothing, and even self-defense gear.
