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 SHARP Announces Millionth Contrast LCD Display
25.12.2005
Sharp has announced the development of an LCD display that it calls "mega-contrast". It has an absolutely incredible contrast ratio of 1000000:1 (a million to one).
Recall that in modern LCD monitors that can be bought in a store, the contrast ratio is about 1000:1 (sometimes less - 700:1), and the highest contrast display, which belongs to the professional category, has a ratio of 3000:1. True, SED, which is a joint venture between Canon and Toshiba, recently launched an LCD TV with a contrast ratio of 100000:1. The contrast of the "mega-contrast" display exceeds the theoretical limits for CRT, plasma and organic electroluminescent displays.
According to Sharp, this was achieved through the use of a combination of "unique" technologies developed by Sharp over the past few years. Moreover, Sharp emphasizes that the extremely high contrast ratio did not affect the power consumption of the display. It is as low as it should be for conventional LCD displays.
At first, Sharp is going to use its "mega-contrast" display in professional monitors for video engineers, who usually work in darkened rooms (where you can appreciate the "million" contrast). They will be released under the name Advanced Super View Premium LCD. But Sharp also has plans to enter the consumer market (when prices for "mega-contrast" monitors drop to an acceptable level).
Other technical characteristics of these LCD displays: diagonal - 37 inches, resolution - 1920x1080 pixels, brightness - 500 cd/m2.
