Why does the sky turn red in the morning and evening dawn?

The red color of the sky at sunrise and sunset, as well as when the luminary hangs low above the horizon, is due to the fact that in these cases its rays pass through a thicker layer of atmospheric air, which scatters blue and violet rays more strongly, and red and yellow rays are weakened less.

What artist, inspired by the work of another, completely remade his fresco?

One day, Raphael agreed with the key keeper of the Sistine Chapel and entered it to look at the process of Michelangelo's work on the ceiling painting. Being greatly impressed, Raphael returned to his fresco of the prophet Isaiah in the Church of St. Augustine, scraped it off and painted it again in a different manner, imitating Michelangelo.

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 ... >>

Record Density DDR5 Chips 24Gbps 19.12.2021

South Korean memory chip manufacturer SK Hynix announced the successful development of DDR5 DRAM chips with an industry-leading 24Gb chip density.

SK Hynix released the first DDR5 DRAM chip with a density of 16 Gb in October 2020. And now the South Korean manufacturer is increasing the density to 24 Gb (the DDR5 standard provides for a peak density of 64 Gb).

The new memory is based on improved 1anm technology using hard ultraviolet (EUV) lithography. Manufacturer claims up to 33% higher yield and speed with 25% lower energy consumption than current products

The new chips will form the basis of future 5 and 48 GB DDR96 modules, which will first find use in data centers, and then probably get to consumer PCs.

SK Hynix has already shipped the first samples of the new memory to customers, and large-scale shipments will begin next year. In a press release, among the partners, Intel is indicated, which is preparing to release 4th generation Xeon Scalable server processors (Sapphire Rapids) with DDR5 and PCIe 5.0 - they will be based on the current Golden Cove architecture (Core 12th generation).
