What is a fossil?

The study of fossil plants and animals helps in the study of our past and allows you to find out what animals lived millions of years ago. This is the science of paleontology.

Some people think that fossils are the remains of animals that lived a very long time ago. There are actually three types of fossils. The first type includes parts of organisms that have escaped decomposition and have survived to this day in their original form. Fossils can be in the form of a cast or impression that repeats the shape of the body of an animal or plant after the animal or plant itself has disappeared. Fossils can also be traces of animals left by them on a soft surface of mud or clay.

If they find a fossil consisting of some part of the body, then these are mostly dense parts - the skeleton, the shell, which have survived to this day. Soft tissues are decomposed. But in some cases, even animals such as jellyfish, which are 99% water, leave beautiful prints on the rocks. Some fossils found in the ice have preserved not only the skeleton, but also the tissues on their bone formations.

The quality of a fossil does not depend on its size. For example, a small ant that lived many millions of years ago is perfectly preserved in a piece of amber. The degree of preservation of an animal or plant depends on the region of their residence. The most numerous are fossil marine animals - after their death, their bodies are quickly covered with bottom sediments and thus protected from decomposition. Terrestrial animals and plants are subject to the destructive effects of air and the environment.

It is mainly through the study of fossils that we know what the animal world was like hundreds of millions of years ago. For example, fossils found in rock told us that millions of years ago there was an age of reptiles, during which there were monsters 24 meters long and weighing 56 tons. They were dinosaurs. We also learned about the very first bird, called "Archaeopteryx", from two casts found.

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. ... >>

Washing people with ultrasound 29.10.2022

If bubbles, rose petals, and scented candles aren't enough to soothe you after a long day, your dream bath might be just around the corner. Scientists in Japan are developing a "human washing machine" that cleanses your body as it plays a relaxing video selected for you by artificial intelligence.

An ultrasonic bath blows users with high-speed water containing very fine air bubbles that remove dirt from the pores.

This is the development of Science, a technology company in Osaka that creates shower heads and bathtubs using this bubble technology.

The product, dubbed "Project Usoyaro", is expected to be completed by 2024 and then showcased at Osaka in 2025. Its goal is to "wash the mind" as well as the body, creating the most comfortable experience for the user.
