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 ... >>

Wireless speaker Samsung Music Frame HW-LS60D 06.05.2024

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 ... >>

Random news from the Archive Charging electric vehicles while driving 19.05.2021 The problem of battery charging is one of the reasons preventing the widespread use of electric vehicles. Perhaps the development of researchers from Cornell University in the USA, who have created a technology for charging batteries while an electric car is in motion, will help solve it. The development was led by Khurram Afridi University, Associate Professor of Electrical and Computer Engineering, who has been working on a project for the past seven years to introduce infrastructure for wireless car charging on American roads. In their work, the researchers used the achievements of Nikola Tesla, who 100 years ago used alternating electric fields to power flashlights that were not connected to the network. The new technology involves embedding special metal plates in the roadway connected to a power line and a high-frequency inverter. These plates will create alternating electric fields that attract and repel pairs of plates attached to the bottom of the electric vehicle, generating power. Researchers have already made some progress. With their technology, electric vehicles with a ground clearance of up to 18 cm can be propelled. In addition, charging continues even if the electric vehicle is driven on a road with plates that are several meters apart and not completely aligned. The new technology can now fully charge the battery of a small electric vehicle such as the Nissan Leaf in 4-5 hours. The main difficulties during the development process were related to the selection of suitable components that could withstand high voltage, as well as suitable for use in different weather conditions. To integrate the new technology, major repairs of public roads will have to be carried out, which requires the allocation of huge funds. According to scientists, electrification should begin with busy highways and main roads in large American cities.
