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 Robots milk cows
10.02.2013
Despite the fact that modern robots are still primitive machines, they have already become an indispensable tool for solving a variety of tasks. First of all, repetitive actions are implied, robots are good because they do not need rest, they do not arrange protests and do not organize labor unions to demand higher wages. And robots are constantly improving and mastering new skills.
American Kevin Kueker, a third-generation dairy farmer, spoke about a technical innovation at his enterprise. He installed a robotic milking system on his farm as part of an overall equipment upgrade program, and this happened about a year ago. The principle of operation of the machine is relatively simple, when the cow is ready for milking, she goes to a specially equipped stall.
A scanner connected to a computer identifies the animal by an electronic chip, and a 3D camera determines where the cow's udder is. When all the necessary data are collected, the milking procedure begins, and at the end of it the animal receives a treat. The robotic system is not cheap, its cost is 150 thousand dollars, which means that at the current stage it is appropriate only for the largest enterprises.
