Invented fabric that mosquitoes won't bite through

25.05.2023

American scientists have developed a thin fabric through which mosquitoes cannot advance their proboscis. This is a fabric with a special weave, quite light, so that in summer clothes made from such material will not be hot.

The publication writes that Auburn University professor John Beckman during a hiking trip decided to figure out which fabrics are inaccessible to mosquito punctures. He put on sleeves made of different fabrics and held out his hand to a container filled with mosquitoes to check which fabric was easily bitten by bloodsuckers. Mosquitoes coped with most fabrics without difficulty.

The most inaccessible to mosquitoes were knitted fabrics formed not due to interlaced threads, but loops. Scientists took advantage of this opportunity and tested the effectiveness of the protection provided by different weaving options.

Initially, scientists noticed that the interlock fabric, consisting of two layers of loops, proved to be the best. An additional increase in the thickness of the threads and a decrease in the size of the loops increased protection. Polyester and spandex threads also showed themselves better than others - they often blocked mosquito bites.

It is noted that Auburn University is preparing to patent the best options for protection against bites in order to then license them to clothing manufacturers.

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. ... >>

Interchangeable optics for smartphone 12.07.2020

Huawei continues to work on methods to improve the quality of shooting in smartphone cameras. The next patent received in the European Intellectual Property Office (EUIPO, European Union Intellectual Property Office) describes the use of interchangeable optics for a smartphone.

Huawei now has the flagship Huawei P40 Pro + with a 10x optical zoom in its assortment. Such parameters are achieved using the periscope module of the main camera. At the same time, the Huawei P40 Pro consistently ranks first in the DxOMark ranking, and the Huawei P40 Pro + has not yet been tested by the specialists of this laboratory.

However, with all its advantages, periscope modules also have disadvantages. Huawei has found a way around them in a new patent. It describes a smartphone with a triple main camera, where two sensors are relatively small and a larger third sensor can be used with interchangeable lenses.

Motorola has already tried to implement a similar development with Moto Mod modules, but has not been successful. As is usually the case with patents, it is currently impossible to say with certainty whether the project will be brought to a commercial stage and whether its implementation will appear on store shelves.
