What makes animals see red?

The myth that red makes the bull angry has been around the world since at least 1580. It was then that the well-known novelist and playwright John Lily wrote: "He who appears before the Elephant should not be dressed in bright colors, just like the one who appears before the Bull, in red."

Whether we like it or not, the fact remains that, like rats, hippos, owls, and anteaters, bulls are color blind. The bull does not rush to the red - the menacing movements of the matador's cloak infuriate him, but the color only serves to please the crowd.

Dogs can distinguish between yellow and blue, but cannot distinguish between red and green. At traffic lights, guide dogs decide if they can cross the street by listening to the traffic noise. Hence the beeping signals at modern pedestrian crossings.

Chicken is a completely different matter.

Chicken workers know all too well what happens when a chick "sees red." As soon as a drop of blood appears on one of them, the rest immediately rush to the poor fellow and begin to peck as if possessed.

Such cannibalistic behavior - if left to chance - can lead to mass murder and a rapid decline in the number of poultry on a poultry farm.

The traditional solution to this problem is to cut chicken beaks with a hot knife: a blunt beak causes much less damage. However, in 1989, Animalence proposed a radically different way out of the situation: they launched red contact lenses for laying hens. The first results of the experiment seemed promising: as everything turned red, the hens fought less and, as soon as their activity dropped significantly, they ate less, continuing to carry the same number of eggs.

The egg-producing industry gives a very small percentage of profit - 1,6%. In total, there were 250 million laying hens in the United States at that time, of which 150 million were kept on fifty poultry farms. Red contact lenses promised a triple increase in profits.

Unfortunately, the process of "putting on" contact lenses turned out to be too time-consuming and troublesome. Deprived of oxygen, chicken eyes quickly degraded, causing suffering and pain to the birds. Under pressure from animal rights activists, Animalence had to abandon the production of its products.

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 ... >>

SteelSeries Prime Mini and Prime Mini Wireless mice 23.09.2021

SteelSeries introduced the Prime Mini and Prime Mini Wireless mice. The new mice have found application technology Prestige OM.

Under this name lie the magneto-optical switches previously tested in Prime mice, from which the new devices differ in smaller size and weight. More specifically, the Prime Mini is 12% lighter and the Prime Mini Wireless is 9% more powerful than the base model.

The benefits of Prestige OM switches are five times longer "than the competition" and "lightning fast response time". Unlike mechanical switches, magneto-optical switches do not wear out during operation, that is, their characteristics remain unchanged.

The Prime Mini weighs 61g and uses the TrueMove Pro sensor.

The Prime Mini Wireless weighs 73g but is wireless. Without recharging, this mouse can work for more than 100 hours. It uses the TrueMove Air sensor.

The SteelSeries Prime Mini gaming mouse is priced at $60 and the Prime Mini Wireless is $130.
