What benefit did farmer Seth Wright gain by noticing a mutation in his flock of sheep?

In 1871, a lamb with unusually short legs was born on the farm of Seth Wright (Massachusetts, USA).

The astute American decided that such a sheep would not be able to jump over the low stone fence of the farm and, taking advantage of the opportunity, deliberately brought out a line of short-legged sheep.

 Random interesting fact from the Great Encyclopedia:

What is a sticky shell?

If you have ever been to the sea and walked near breakwaters, boulders, protective walls, then you probably saw shells that stuck. That "crust" that you probably noticed on breakwaters and boulders consists of many millions of shells stuck.

A sticky shell is just a small mollusk. When they are born, they are free-floating. But, having reached the adult state, they no longer move, but attach themselves to any suitable surface and completely lose their ability to move. Since they tend to cling not one by one, but in millions, they are a serious hindrance to a person.

For example, when these shells form a crust on a ship's hull, they can cut its speed in half! In the old days, when the ships were very small, shells were a real danger, made it difficult to control the ship and could even delay it and not allow it to arrive at the port at the appointed time. Pirates who sailed in the Caribbean were forced to capsize their ships on the shore and clean off shells.

Whalers of old times had great difficulty returning home after a two-year voyage because of the huge quantities of shells stuck to the hull of the ship. Even in our time of modern, powerful ships, shipping throughout the world suffers huge losses due to shells, which cause loss of time and increase wear on propulsion systems.

There are many varieties of sticky shells, among which there are shells that prefer to live on rocks rather than on wood and metal. As we have already said, only when they are born, they resemble small crabs or lobsters and can move around. But as soon as the shell attaches to any surface, it already remains there for life!

At the attached shell, the shell continues to grow, which completely covers its body. In this case, her tentacles or antennae remain the only movable organ. She has six pairs of these tentacles, with which she is able to move in order to reach out to some small marine organisms and draw them to her.

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 ... >>

Wireless charging from Intel 21.08.2012

Intel, the world's largest semiconductor supplier, plans to integrate support for wireless mobile charging into chips it makes for laptops. The company plans to do so in the second half of 2013 and use technology it has developed itself, according to DigiTimes, citing supply chains.

Intel wireless charging technology is planned to equip ultrabooks and smartphones with Intel processors. The technology will use an ultrabook as a power source, complete with appropriate software and a "transmitter" that will charge the smartphone "over the air".
According to Intel's specifications, the technology will have low power consumption, while the smartphone can be placed near the laptop in any position, and not some special one, specifies DigiTimes.

In addition to the technology itself, Intel offers options for placing the necessary components in a laptop and smartphone. The company offers streamlined design solutions that will allow third-party manufacturers to add support for wireless charging at a minimal cost.

Wireless charging technology is already in some products. For example, in some models of Sharp smartphones for the Japanese operator NTT DoCoMo, as well as in the Palm Pre smartphone. Samsung Electronics planned to release a wireless charger in June, but the project was postponed until the end of this year or early next year due to the need for improvement.

As early as 2008, Intel Corporation demonstrated its interest in wireless power transmission. As part of the Intel Developer Forum conference, scientists showed an installation that transmitted energy at a distance of 60-90 cm, sufficient to power a 60 W lamp. Once again, the company staged a demonstration at the Computex exhibition in June 2012. And this time, Intel showed an almost ready-made solution integrated into a laptop. The power of the system was 3 W, which is quite enough to charge a mobile phone. An example of a tandem was shown based on an Acer Aspire ultrabook and an Android smartphone.
