Tesla Rodster will bring terrestrial bacteria to Mars

24.02.2018

Scientists from the American Purdue University fear that the legendary car Elon Musk Tesla Rodster in the event of a collision with Mars will bring terrestrial bacteria onto it.

Such an assumption of scientists arose not simply. So, NASA spacecraft before being sent into space undergo a thorough treatment of bacteria in order to avoid getting earthly "inhabitants" to other planets. Elon Musk's company did not carry out such a procedure.

“If there is biological life on Mars, then it risks mixing with organisms from Earth. Will the terrestrial representatives be more adaptable and conquer Mars in such a way that we do not know what kind of biosphere it had? Or they will not be able to adapt better Martian organisms? We don't know," the scientists said.

Experts also recalled that radiation, low temperatures and pressure, of course, affect bacteria very badly, but do not kill them completely.

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. ... >>

Wireless solar powered hair dryer 15.11.2021

Chinese startup Zuvi is launching its light-powered wireless hair dryer.

The device uses light energy to quickly dry hair like wind. The maximum rated power is 290W. The hair dryer can be charged up to 90% in 19 minutes and weighs only 630g.

Zuvi drying technology is to accelerate the evaporation of moisture from the hair due to heat. Radiation is the most efficient method of heat transfer.

In addition, the technology does not damage the hair. The principle of light-force heat transfer is that water molecules selectively absorb certain wavelengths of infrared light. Most of the energy is absorbed by the water molecules outside the hair.

Since the temperature of the surrounding air, hair and scalp does not rise, the hair retains its natural moisture and has a lower electrical charge. This reduces hair damage.

The Zuvi hair dryer has 15 built-in sensors that collect a range of data including hair moisture content, light and wind energy efficiency and drying time. Light and wind power are optimized depending on the temperature and humidity of the air during the use of the dryer.
