Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Fish in outer space 23.07.2023

China is preparing to send zebrafish to the Tiangong space station to study their interactions and effects on other organisms in a limited, closed ecosystem. The main focus of the study will be on the study of the possible loss of bone density in astronauts during prolonged stay in a microgravity environment.

The new study aims to study the loss of bone density that astronauts can experience during prolonged exposure to zero gravity. This issue could have a significant impact on future space missions.

This is not the first time fish have been sent into space. In 1973, a group of fundulus fish were sent into Earth orbit to the first Skylab science laboratory to study their response to weightless conditions.

The fish managed to successfully incubate dozens of eggs, from which newborn fish fundulus emerged, able to adapt to weightlessness.

Also, the Japanese space agency conducted a study of the effects of microgravity on a small group of medaka fish aboard the International Space Station.

The results of the study showed that the fish experienced a significant deterioration in well-being and, almost immediately after arriving at the ISS, began to lose bone density. Typically, such effects are observed in astronauts after about 20 days of stay in the space environment.
