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 ... >>

Sensorwake Trio wakes you up with smell, light and sound 16.06.2018

The KickStarter website raised funds for the release of an unusual alarm clock. The Sensorwake Trio wakes you up with smell, light and sound.

In order for the alarm clock to wake up with a smell, special cartridges are inserted into it. The developers emphasize that the cartridges are dry and easy to handle. One is enough for 30 days (subject to one wake-up call per day). It will be possible to choose the smell of coffee, the sea coast, mint, cookies, fresh grass and other aromas. A minute after the activation of the evaporator, the backlight turns on, and a minute later - a "motivating melody" (five pieces are offered to choose from).

Sensorwake Trio dimensions are approximately 10 x 10 x 12,5 cm. The device is powered by an AC adapter. In the event of a power outage, a backup battery provides operation.

For one device with two cartridges, fundraisers are asked for $79. Six cartridges cost $15, half the suggested retail price. Other lots available. Shipping should start in November of this year.
