Where is the Eastern Garbage Continent located?

There is an area in the North Pacific called the Great Pacific Garbage Patch or the Eastern Garbage Continent. Under the influence of ocean currents, a large amount of plastic waste from Asia and America has accumulated in the upper water layers, probably more than 100 million tons of garbage.

Unlike biodegradable waste, plastic only breaks down into small particles under the influence of light, while maintaining the polymer structure. This suspension resembles zooplankton, and jellyfish or fish mistake plastic for food.

Why is a 660-ton steel ball installed in a Taiwanese skyscraper?

Usually giant pendulums are installed in large clock towers. But the 660-ton steel pendulum in Taiwan's Taipei 101 skyscraper performs a different role - an inertial vibration damper. It is located between the 87th and 91st floors of a 101-storey building with a total height of more than 500 meters and serves to reduce the risk of collapse during an earthquake or hurricane.

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 ... >>

Hot Springs of Mars 02.12.2012

Hydrothermal crevices around Martian craters may have once been a habitat for microbes. A new joint study by the University of Leicester and the Open University, published this week in the journal Earth and Planetary Science Letters, proves that the water on Mars was warm enough to support life. The study establishes that the range of water temperatures on the planet was from 50 to 150 degrees Celsius. Microbes on Earth are able to live in such water, for example, in the volcanic hot springs of Yellowstone Park.

The work of scientists was based on a detailed study of meteorites from Mars using powerful microscopes at the Department of Physics and Astronomy at the University of Leicester. This was followed by work on computer modeling carried out at the Open University.

Lead study author Dr. John Bridges said: Earth has meteorites from Mars.The most interesting of them are nakhlites - named after a Martian meteorite found near the Egyptian city of Nakhla.Meteorites from this group are penetrated by small "veins" filled with minerals.And these minerals were formed by the action of water near the surface of Mars ".

Dr. Bridges and his group studied the Nakhlite in detail. Only eight of them are known, and all of them have, albeit small, but significant differences in the composition of minerals. The Lafayette meteorite gave scientists the most information - the most complete and informative selection of minerals was found in its cavities. Careful study showed that the earliest material to form along the walls of meteorite "veins" was iron carbonate. It forms in CO2 enriched water at a temperature of about 150 degrees. When the water was cooled to 50, then clay minerals began to form, which passed from the crystalline to the amorphous phase and had the same composition as clay.

By combining data from both universities, the researchers determined the properties of water on Mars. Initially, it was about 150 degrees and contained carbon dioxide, forming carbonates, and then cooled to 50, forming clays. Despite the fact that clays were also detected by orbiters on the surface of the Red Planet, the spatial resolution of the images was insufficient to draw definite conclusions. Until scientists studied nakhlites in detail, it was not known that carbonates form first, and only after them clay when water cools.
