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 ... >>

Electric car Polestar 2 23.02.2019

Polestar, a subsidiary of Volvo Car Group and Zhejiang Geely Holding, has unveiled its second vehicle, the Polestar 2. Unlike the hybrid first-born Polestar 1, the Polestar 2 is a purebred battery-electric vehicle and the brand's first mass-produced model.

The five-door fastback model (in this case a sedan with a sloping roof and a miniature trunk lid) shares the same boldly angular design as its predecessor. The Polestar 2 is built on Volvo Car Group's proprietary Compact Modular Architecture platform (CMA).

A pair of electric motors with 300 kW (408 hp) and 660 Nm of torque provides all-wheel drive and acceleration from 0 to 100 km/h in less than 5 seconds. The 78 kWh (72 kWh in China) floor-integrated battery consists of 27 modules and is designed for a range of 500 km (WLTP/NEDC) or 275 miles (EPA).

The 11-inch touchscreen infotainment system is built on the Android platform, including Google Assistant services, Google Maps and other applications from the Google Play Store. You can control the settings and modes of the electric vehicle using a smartphone using it in Phone-as-Key mode.

The Polestar 2 will only be available through online pre-order, starting at €59,900 in Europe and $63,000 in the US.
