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 ... >>

Viable artificial lungs created for the first time 07.08.2018

Scientists at the University of Texas at Galveston have grown lungs for the first time and successfully transplanted them into pigs, which survived for several weeks after the operation.

Healthy blood vessels developed in the tissues of the transplanted lungs, as a result of which the organs were able to engraft. In previous experiments, lungs transplanted into rodents stopped functioning within hours. In addition, the organs are grown from the recipient's own cells, which reduces the risk of rejection due to the immune system.

During the experiment, scientists using a mixture of detergents and sugar separated cells from the lungs of donor pigs, resulting in a 3D scaffold of intercellular proteins. In it, scientists began to grow a culture of cells isolated from recipient animals. The lungs grew for 30 days in a bioreactor tank filled with nutrient solutions. Ready organs were transplanted to four pigs to replace the left lung.

Animals were sacrificed 10 hours, two weeks, one month and two months after the operation. They underwent an autopsy to assess how well the organs took root. During the entire experiment, the pigs did not receive immunosuppressants, but the scientists did not reveal signs of rejection of the transplanted organ in any of the cases. At the same time, the researchers note that the artificial organs were not functional because they did not connect to the pulmonary arteries.

Scientists hope that in the future they will be able to improve the method and get full-fledged organs. In the case of transplanting an artificial lung to a human, 3D printing can be used to create a framework.
