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 ... >>

Australian rock art 10.05.2011

In the north of Australia, in the area where people who sailed from Indonesia are believed to have landed for the first time 50-60 thousand years ago, archaeologists have found thousands of drawings made on the rocks with red and orange mineral paints. Moreover, so far the expedition has studied only ten square kilometers of the vast rocky desert, where the drawings are found.

Apparently, over the centuries and millennia, the style and content of the drawings changed: over the elongated figures of people, often armed with boomerangs and darts, images of local animals were later applied with a brighter pigment. It is not yet possible to determine the age of this art gallery in the desert. Carbon-14 dating requires organic matter, which ancient paints do not have.

Only on one "fresco" was found a long-dried nest of wasps - it is 17 years old (this coincides with the age of the drawings of a prehistoric man in the French cave of Lascaux). So the drawing is older than the hornet's nest. But for a more accurate determination, it is necessary to analyze the paints using X-rays, and for this it is necessary to deliver an X-ray spectrometer to the desert.
