Alaska is melting

17.09.2011

Almost the entire coast of the Arctic rests on permafrost. Parts of the Alaskan coastline along the Beaufort Sea are over 70% ice. Global warming weakens the permafrost, and during severe storms, pieces of the coast fall off into the ocean, up to 10 meters wide and several meters thick.

In addition, many meters of ocean ice recedes from the shore, protecting the earth from wave erosion. Along the entire coast of Alaska (taking into account the winding coastline, its length is 60 thousand kilometers), the coast is melting at a rate of half a meter per year. 178 towns and villages are under threat.

True, according to calculations, the coastal houses of most of these settlements will fall into the ocean only after 350 years, but three settlements will last no more than 10-15 years. Among them, for example, the village of Shishmarev, where a school, leather workshops and other buildings built many years ago, far from the water, were built directly by the sea.

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 ... >>

CC3200+CC2650 Wireless Gateway Connects BLE Sensors to the Internet 26.09.2015

Texas Instruments is offering a reference design for a miniaturized Internet>Bluetooth Low Energy Gateway that is based on two new CC3200 (WiFi) and CC2650 (BLE) chips.

Considering that the CC2650 chip also supports other standards in the 2.4 GHz band and that it is almost completely compatible with the CC1350 (Sub1GHz + BLE 2.4 GHz), the board developed by TI can be the basis for a universal bridge (gateway, hub) between the Internet and almost all other wireless devices of different standards.

The gateway can even support proprietary protocols in the 433/868 MHz bands, whose packets can be received / transmitted using the CC1350 multi-band radio.

Development Features:

Connecting BLE devices to the Internet of things;
USB powered;
Configuration via UART terminal (USB);
HTTP server and configuration pages;
Single board WiFi-BLuetooth solution;
Support for the MQTT protocol for IoT;
Firmware update over the air.
