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 ... >>

The smallest magnifying glass sees bonds between atoms 21.11.2016

Scientists from the British University of Cambridge and the Spanish University of the Basque Country have presented a model of the world's smallest magnifying glass that can see the processes inside the molecule.

The scientists used highly conductive gold nanoparticles to create a subminiature cavity as a cavity, allowing light to be trapped at less than one billionth of a meter. A laser was also used to create the cavities, and the instrument required extreme cooling to operate. "We had to cool the samples to minus 260 degrees Celsius to freeze the rushing gold atoms," said Felix Benz of the University of Cambridge, lead author of the work.

"Even individual gold atoms in our experiments behave like tiny metal ball bearings conducting electrons, which is very different from their quantum life, where electrons are tied to nuclei," said Jeremy Baumberg, another participant in the study from the University of Cambridge. .

The system made it possible to observe processes at the level of individual atoms, which opens up new possibilities both in research projects. In addition, scientists believe that the study can be used as the basis for creating new sources of information storage - in the form of molecular vibrations that can be read and written using light.
