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 Drones and Coronavirus 12.06.2021 Malaysian police use drones that can measure temperatures up to 20 meters above the ground. This is another measure to combat the spread of coronavirus. Drones alert regulators to people with high temperatures. Malaysian police have previously warned they will use drones to enforce previously imposed travel restrictions, and officers in some areas have also said they will be making surprise home visits to make sure people are following the rules. Previously, reports have already appeared about how the authorities of various countries used unmanned aerial vehicles to monitor compliance with COVID-19 rules. The Spanish authorities have used drones to make sure people visiting beaches are following social distancing rules. In Brussels, Belgium, police used drones with loudspeakers to urge people to "stay at home". In Australia, drones have been used to catch people without masks, as well as to scan cars parked more than 5km from their owners' homes. In the UK, authorities have come under fire for using drones to monitor dog owners to see if they stray too far from home.
