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 ... >>

Mathematical regular distribution of neurons in the human brain 04.01.2024

Scientists from the Jülich Research Center and the University of Cologne in Germany, participating in the Human Brain Project, have discovered a surprising mathematical rule governing the distribution of neurons in the brain. It has been confirmed that the number of neurons in the outer layer of nervous tissue in various mammalian species follows a lognormal distribution.

The discovery of a lognormal distribution of neurons in the outer layer of the cerebral cortex across mammalian species has important implications for understanding brain function and evolution. This information can serve as the basis for the creation of accurate models that facilitate research into neurological mechanisms, and can provide impetus for the development of innovative treatments for various neurological diseases, alerting us to potential problems and improving quality of life.

The findings provide scientists with the key to creating precise models that will help unlock the mysteries of brain function and develop new treatments for neurological diseases.

The lognormal distribution, familiar in the world of statistics, becomes a striking revelation when analyzing neurons. This mathematical concept appears in nature, similar to the normal distribution, but with skewness and a pronounced right-sided tail. It is important to note that this distribution is also found in population, where large cities are combined with many smaller settlements.

Brain structure and function are closely related to the number and distribution of neurons. The diversity of neuronal densities in different parts of the cerebral cortex varies significantly.

The study used data from seven different mammal species, including humans. A comparative analysis of the density of neurons in different areas of the cerebral cortex revealed a general pattern of lognormal distribution.

The lognormal distribution becomes a natural result of various processes in a developing organism, just as the normal distribution is associated with the summation of independent variables.

The new study not only expands our understanding of brain structure, but also provides a basis for future research into treating neurological disorders. Attention to the mathematical patterns of neuron distribution opens up prospects for creating more effective methods of treating and combating brain diseases.
