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 ... >>

Silicone film smoothes wrinkles 30.05.2016

For most of us, aging is associated not with mutations, not with chromosomal telomeres, not with wear and tear of mitochondria, but with wrinkles.

Indeed, the skin ages quickly and begins to look unimportant - but the problem here is not only in poor appearance: losing elasticity and strength, the skin ceases to protect us from bacteria, toxins, heat and cold, radioactive radiation; finally, she does not regenerate well when injured. And how good it would be if spoiled, aged, unusable skin could be replaced with an artificial analogue.

Scientists at the Massachusetts Institute of Technology, led by Daniel Anderson (Daniel Anderson) have created a polymer film that has the elasticity and strength of real skin.

The skin-like film was made from filaments of siloxane, the so-called variety of organic compounds whose molecules are built on the basis of a skeleton of silicon and oxygen atoms. The researchers tested about a hundred siloxane polymers cross-linked via chemical bonds; as a result, we managed to find one that best suited real human skin.

The "synthetic coating" is more stretchable (the siloxane film could be stretched 250 times, after which it returned to its original state, while the skin can only be stretched 180 times), in addition, the authors of the work claim that their material is better suited for wound dressing. than conventional silicone and polyurethane hydrogels.

The process of applying the film to the skin takes place in two stages and is similar to a conventional cosmetic procedure: first, a polysiloxane raw material is applied, and then a catalyst is added, which triggers the formation of additional chemical crosslinks between the siloxane molecules.

The most important thing is that the whole procedure has already been tested on volunteers: the film itself cannot be seen in any way, but at the same time it improves the appearance of the skin itself - for example, with the help of a new product, it was possible to reduce wrinkles and bags under the eyes. In other words, the siloxane film returned to the aged skin the lost firmness and elasticity.
