How did the commander of the second lunar mission joke about Neil Armstrong?

At 169 cm tall, Charles Pete Conrad was one of the shortest astronauts in history. As the commander of the second lunar mission "Apollo 12", he was the first of the team to descend to the surface of the satellite. Sneering at his height and Neil Armstrong's famous words about a small step for him and a giant leap for all mankind, Conrad said his first phrase: "Wow! He may be small for Neil, but big for me."

What football player can be called the antipode of the legendary ghost ship?

The nickname in honor of the legendary ghost ship "Flying Dutchman" was given to many Dutch aircraft designers, athletes, and musicians. But the "non-flying Dutchman" is also known - this is how football player Dennis Bergkamp was nicknamed because of his aerophobia. Speaking for Arsenal, he flatly refused to fly on planes, which is why he was forced to miss important European Cup matches in continental Europe.

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 ... >>

DNA of things 28.11.2019

Researchers from Switzerland and Israel are developing a way to store large amounts of information in almost any facility. So, they created glass nanoballs - "DNA molecules" - with "instructions" for printing an object on a 3D printer, and "sewn" them into the object itself.

This development was preceded by two discoveries of the last few years. One is Robert Grass's method for labeling foods with a DNA barcode embedded in tiny glass beads. Such nanoballs are used, for example, as indicators for geological tests or as markers by which a high-quality food product can be distinguished from a counterfeit one. A barcode is a 100-bit code (a combination of "0" and "1" in one hundred characters).

At the same time, it became possible to store huge amounts of data in DNA. Grass' colleague Yaniv Erlich, an Israeli scientist, has developed a method that could theoretically store 215 terabytes of data in one gram of DNA molecules. And Grass was able to store an entire music album in DNA, which is 000 megabytes of data.

Now scientists, having combined their inventions, are creating a new way of storing data - the "DNA of things". As an example, the researchers 3D printed a plastic figurine of a rabbit, which contains instructions (about 100 kilobytes of data) for printing an object. The researchers achieved this by adding tiny glass beads to the plastic containing information about how and what the object is made of.

And just like in biology, this new technological method preserves information for several generations. By extracting the "instruction" from a small part of the figurine and using it to print a new piece, the scientists were able to repeat the printing five times, creating a "great-great-great-grandson" of the original rabbit.

The technology can be used to label drugs or building materials such as adhesives or paints. Scientists explain that quality information can be stored directly in the preparation or material itself. This means that health authorities can read product quality control test results directly from the product. And workers who renovate a building can find out which manufacturer's products were used in the building's original structure.
