Why is one of the whites of the human eye named after Pikachu?

In 2008, Japanese scientists at the Osaka Institute of Biological Sciences discovered a protein that plays an important role in signaling between the ribbon synapses of the human eye's photoreceptors and dendrites. They named this protein "Pikachurin" - in honor of the movement at lightning speed and the electrical abilities of the Pokémon Pikachu.

What is radio astronomy?

In 1931, a communications engineer at Bell Laboratories was investigating atmospheric radio interference that could affect transoceanic telephone communications. He caught some noises, clearly not coming from a thundercloud, but from somewhere in space. He discovered that it is possible to receive radiation from the galaxy. Thus was born a new branch of astronomy - radio astronomy.

Radio astronomy is developing in two directions. With the help of special antennas, it is possible to capture the radiation of space objects. This may be thermal radiation (radiation of radio waves emitted by any hot body). But there are also noises, or static interference of cosmic origin, also picked up from space, but not at all thermal in origin. Another branch of radio astronomy is sending signals to objects such as meteors and the Moon and picking up their reflections. This is how radar works.

Radio astronomy is most useful for studying the Sun, meteors, the Moon, and the planets of the solar system. By capturing the reflection of rays from meteors, we learn a lot about their orbits. Exploring the moon using radio astronomy techniques, we learn a lot about its surface. So, even before people set foot on the moon, thanks to radio astronomy data, scientists already knew that its surface is a rock crushed into dust. Probably one of the most exciting areas of radio astronomy is the search for signals from other worlds.

Now radio telescopes have been improved to the point where they can pick up signals coming from a distance of almost eighty trillion kilometers. What signals are scientists hoping to pick up? It is believed that if somewhere in deep space there is a civilization other than ours, and it wants to make its presence known, then our brothers in mind will probably send some very simple signal, such as a series of numbers.

It is also believed that these signals are likely to be received at a purity of 1420 MHz - the frequency at which simple hydrogen emits radiation waves in outer space.

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 ... >>

300 GB freeze-ray optical disk storage system 16.03.2016

Panasonic unveiled an optimized 300GB freeze-ray optical disc storage system at the OCP Summit held on March 9 and 10 in San Jose, California, USA. The new product is expected to hit the market in the second half of 2016 and will be used in the next generation of high-performance data centers, where it will complement traditional hard disk and tape storage tools.

The Panasonic optical disc system is already being used by corporations and government agencies whose activities require long-term data storage. The announcement of the freeze-ray system, which was developed and tested in the data centers of a cloud service provider in the United States, took place at CES 2016 in Las Vegas, USA. The first generation of the system used 100 GB Blu-ray discs.

To increase storage capacity, the optimized freeze-ray system uses 300 GB Archival Discs, which provide 1,9 PB (1 petabyte = 1 terabytes) of storage in a standard 000-inch rack.

As noted in Panasonic, data centers need tools for secure data storage for many decades. Non-rewritable Archival Discs meet these requirements. Being WORM-carriers (Write Once Read Many), they ensure the impossibility of overwriting or falsifying existing data and the estimated shelf life of over 100 years, the company says. Drives can be used at room temperature, which reduces data center power costs.

Going forward, Panasonic plans to expand the capacity of the Archival Disc to 500 GB and 1 TB to create even larger storage systems totaling several petabytes. The use of freeze-ray will contribute to the further evolution of data centers and reduce the cost of data processing and storage.
