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 ... >>

Plastic skin feels the force of touch 22.10.2015

Stanford University engineers have created a plastic "skin" that detects the force of touch and generates an electrical signal that conveys this information to living brain cells.

Seventeen specialists led by Professor Zhenan Bao, who has been working on this direction for ten years, have developed a material that mimics such properties of human skin as plasticity and healing ability. In addition, the invention includes a network of sensors that sense and send information about touch, temperature, and pain to the brain. Ultimately, this development should find application in prosthetic limbs.

According to Ms. Bao, for the first time, it was possible to obtain such a material capable of detecting pressure and transmitting signals to the nervous system. The top layer creates a sensitive mechanism. At the same time, the sensitivity of the sensors is the same as that of human skin. That is, artificial skin is able to easily distinguish between a light touch of a finger and a handshake, for example. The underlying layer transports electrical signals and converts them into biochemical stimuli compatible with nerve cells.

Artificial skin has billions of carbon nanotubes embedded in it. When pressure is applied to the plastic, the nanotubes "squeeze" closer together, allowing them to conduct electricity (the more pressure, the higher the current value).

Flexible electronic components were developed by engineers from PARC. When developing the interface for the interaction of electronics with neurons, the technique of Karl Deisseroth, a well-known specialist in the field of optogenetics, was used.
