Is it possible to speak with a whistle?

Can. On one of the Canary Islands, the island of Gomera, the whistling language, "El Silbo", is still widespread. The words and sentences of this language differ in pitch and are heard at a distance. This language is under the protection of UNESCO. But in everyday life, the inhabitants of the island communicate in Spanish.

How did navigators find water in the Galapagos Islands?

The Galapagos Islands in the Pacific Ocean were discovered by the Spaniards over 300 years ago. Sailors were struck by the abundance of giant tortoises, thousands and hundreds of thousands grazing along the shores and on the slopes of the mountains. They were the only large herbivores on the islands, and despite their very high numbers, they somehow managed not to deplete pastures and trample them. This turtle is called elephant or Galapagos.

Most of the Galapagos Islands do not have fresh water sources, and turtles feed on succulent cacti there. But where there are springs, they gladly eat leaves from the lower branches of trees, eat lichens, grass, fruits of trees and shrubs. They also go to water every day.

Since there are few sources, turtles from all over the island go to the spring, sometimes for several kilometers, trampling wide paths that run to it from all sides. It was on them that the first sailors found fresh water.

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 ... >>

Medical sensor on the nail 30.12.2018

IBM specialists have developed a prototype of a new medical device that allows you to monitor the state of human health and the course of diseases.

A wearable device with a wireless interface is attached to the end of the finger and continuously measures the movement and deformation of the nail - according to these data, artificial intelligence can tell a lot about the state of the body.

Initially, researchers set themselves the task of tracking the progress of Parkinson's disease and evaluating the effectiveness of drugs. To do this, you can use indicators of the integumentary system, including the skin, but in the case of older people, fixing the sensors on the skin is difficult and can cause not only discomfort, but even infection. This prompted the project participants to turn their attention to the nails. It turned out that the analysis of movements and deformations of the nail during the interaction of a person with the external environment makes it possible to judge the state of health and the course of the disease.

The deformations in question are extremely small - on the order of a few micrometers, but the nail is much stronger than the skin, so that the sensors can simply be glued to its surface. Then artificial intelligence algorithms came into play, filtering out that part of movements and deformations that is directly related to mechanical influences during typical actions - opening doors, using a key or screwdriver, writing.

By the way, with regard to writing, the neural network is able to accurately recognize what is written by the deformation of the nails in the process of writing. With the same success, it reveals bradykinesia, tremor and dyskinesia, which are symptoms of Parkinson's disease. One promising application for nail sensors, researchers see systems for communicating with completely paralyzed patients.
