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 ... >>

Technology at the tip of a golden hair 23.10.2006

Scientists from the USA figured out how to add a single molecule of a substance to the reactor, and at a strictly defined moment.

"Chemists have known for a long time that it is technically possible to control the release of individual molecules of drugs or reagents, but no one has tried to implement this idea. We have brought it to the end," says Professor Peter Searson from Johns Hopkins University. He and his colleagues specialize in growing nanowires from various metals using photolithography methods.

In this case, two pure gold electrode wires were needed. A long hydrocarbon molecule was attached to one of them using a gold-sulfur bond. A biomolecule was attached to the other end of the molecule, which needed to be introduced into the reactor at the right time.

When this moment came, a short current pulse was passed through the electrodes, the bond between gold and sulfur was broken and the molecule set off to float freely. After that, you can attach a new molecule to the electrode and repeat everything from the beginning.

"Our system is quite suitable for implantable chips, which ensure the timely release of drugs into the human body," says Professor Searson. "It will also help to carry out chemical reactions with extremely small amounts of a substance."
