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 ... >>

quantum flute 26.07.2022

American scientists have created a "quantum flute" that can make photons move in sync and interact with each other, something they almost never do in nature. The device could help improve future quantum computer designs.

Like the musical instrument of the same name, the team's "quantum flute" is a piece of metal with a long cavity in the middle, accessed by a series of holes from the surface. But this device is designed not for sound waves, but for light.

"Just like with a musical instrument, you can send one or more wavelengths of photons through it all, and each wavelength creates a 'note' that can be used to encode quantum information," said David Schuster, lead author of the study.

In their experiments with the device, the researchers were able to control the interaction of up to five notes, or qubits, at the same time, using a superconducting electrical circuit as the master qubit. This shows that if the system is scaled up, it can greatly simplify the management of future quantum computers.

"If you wanted to build a quantum computer with 1 bits and could control them all with a single bit, that would be incredibly valuable," Schuster said.

A "quantum flute" is a piece of metal with holes drilled into it that can capture and manipulate photons of different wavelengths to encode quantum information. But perhaps the strangest thing about this "quantum flute" is that it works by manipulating photons to do things they rarely do in nature.

These light particles usually do not interact with each other, that is, they pass by or even through each other. Under certain conditions, they can sometimes be made to interact in pairs, but in the new device, the team was able to get all the photons to interact with each other at the same time, after the energy in the system reaches a critical point.

Usually, most particle interactions are one-on-one—two particles bounce off or are attracted to each other. If you add a third, they tend to still interact consistently with each other. But in this system they all interact simultaneously.
