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 ... >>

Random news from the Archive Updated EU requirements for power consumption of appliances in sleep mode 18.04.2023 The European Commission has adopted new rules to reduce the energy consumption of such electrical appliances when they are in "standby" mode. The EU regulation establishing standby and off-state power consumption requirements for electrical and electronic household and office equipment was first approved in 2008. It was last updated ten years ago. The European Commission has not changed the energy consumption limits, but has expanded the list of devices to which they must apply. For example, ecodesign requirements now apply to appliances with an external low-voltage power source, such as small network equipment (including Wi-Fi routers and modems) or wireless speakers. The limits are set to 0,5W in idle or off mode, or 1W if they continue to display information in idle mode. For devices connected to the Internet in standby mode, the limit is set at 2 to 8 watts. The European Commission expects that the requirements for reduced electricity consumption by 2030 will save 4 TWh per year (twice as much as the annual electricity consumption in Malta) and reduce harmful emissions by 1,36 million tons of CO2-equivalent. Ecodesign requirements are mandatory for all manufacturers and suppliers who want to sell appliances that consume electricity in standby and off mode in the EU. Manufacturers have a transitional period of two years until these new rules come into effect.
