Robots work inside people

04.06.2023

US scientists have developed miniature robots capable of delivering medicines directly to the affected organ. Biological "fins" - bacteria and spermatozoa with a non-linear nature of movement were taken as the basis.

Microrobots made from biocompatible polymers have a spherical cavity inside. Devices vibrate and move. The works also have asymmetrical fins, causing them to orbit. The mechanism has already been tested on the bladder of a laboratory mouse.

A group of microrobots was able to attach to the wall of the bladder and transfer more than 90% of the drugs to the organ in 2 days. It is believed that this will allow more effective treatment of various diseases and reduce side effects.

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 ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Growing meat from mushrooms 25.09.2022

Singapore scientists have used button mushrooms to create an alternative meat.

The researchers grew mushrooms on food waste, which allowed them to saturate them with important ingredients and make them more nutritious. I must say that earlier legumes, wheat gluten, soy and even brewer's yeast were used for vegetable analogues of meat.

Scientists assure that their new meat will taste almost the same as the usual one. This is due to the higher content of amino acids, as well as aspartic and glutamic acids. The latter are usually found in animals and give the meat the necessary flavor.

Another new method will allow the reuse of common food waste from agricultural production - wheat stalks, brewer's grains or soybean husks. These wastes, according to experts, are emitted annually 39 and 14 million tons, respectively.

The lead author of the project, William Chen, believes that the use of these products for growing mushrooms allows us to offer a healthier alternative to meat.

Officially, the new technology will work in 2024. Researchers are currently improving the nutritional quality of the new meat and are working to further reduce food waste during its creation.
