BMW car will catch the green wave

04.08.2015

BMW and American startup Connected Signals have launched an app for Apple iPhone smartphones that provides real-time traffic information.

The program is called EnLighten and can be downloaded from the App Store website. After connecting the smartphone to the on-board media center, the owner of the BMW car will be able to see on the central display information about traffic signals in the direction of travel. In particular, the current traffic light mode at the nearest intersection and the time before switching are displayed.

The system allows you to determine the optimal speed for driving in the "green wave" based on data from the navigator and information about the current route. It is assumed that this will save fuel, as well as avoid unnecessary acceleration and braking, and therefore save the life of the car.
It is also noted that in the case of intersections with traffic lights equipped with separate sections of the turn signal, the EnLighten application can show the timer only "arrows" when the driver turns on the corresponding turn signal.

The system is currently in operation in Portland and Eugene, Oregon, and Salt Lake City, Utah, where traffic lights are connected to a dedicated communications network. In the future, the geography of the service is planned to expand.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Underground passages of old Europe 28.04.2012

The soil of Europe, from Hungary to Spain, is riddled with underground tunnels and adits of unknown purpose. Only in Bavaria (Germany) there are about 700 of them, in Austria - 500 and it is believed that 90% have not yet been discovered. There are many of them in Scotland and Ireland.

Often such a tunnel is only 20-50 meters long, the longest in Germany is 125 meters. They go down to a depth of 10 meters. On some you can go to your full height, on others - only by crouching, and there are also passages with a diameter of less than half a meter. They are found both under ancient cities and villages, and among untouched forests, where there has never been human habitation.

There are passages stretching under the cemeteries. There are those starting in the kitchens of old houses of medieval construction. But, although locals often consider tunnels as a means of rescuing the owners of castles during a siege, this is doubtful: the passages end in a dead end. A dead end may be a small cave with several niches in the wall, supposedly intended for sitting. In the walls of the passages there are smaller niches, where, apparently, the tunnellers, who worked with a pick, put a candle or an oil lamp. In some places in the catacombs, the remains of wooden doors with bolts were found. They, as well as coals found in some catacombs (apparently from torches) date back to the XNUMXth-XNUMXth centuries. None of the written sources of those times mention such structures.

The purpose of the tunnels remains mysterious. These could be places of detention of criminals. Or pre-prepared shelters from wars that shook the continent, or from roving gangs of robbers (but for this they are already very uncomfortable and lack an emergency exit). Or they are places for solitary religious meditation. And it is possible that the last adherents of the Druid religion, supplanted by Christianity, were hiding underground.
