Is it possible for mammals to be born from the genetic material of two males without the mother's genes?

In 2010, a group of American scientists used stem cells to grow offspring from the genetic material of two male mice. Female mice were also involved in the experiment, but only as surrogate mothers and intermediate links, and the resulting mice had an X chromosome from one male and a Y chromosome from another. Even earlier, they learned to grow mice from maternal genes without the participation of the father.

Such research, in particular, may help same-sex couples to genetically have their own children in the future.

What is the difference between an airship and a hot air balloon?

69 years after the beginning of the era of aeronautics, in 1852, the Frenchman Henri Giffard designed the first controlled balloon - an airship. He installed a steam engine, a screw and a primitive steering wheel on a balloon. His airship could rise to a height of about two kilometers and reach speeds of up to 10 kilometers per hour. From now on, aeronauts got the opportunity to fly not where the wind blows, but where they needed to.

The design of airships was gradually improved: spherical airships gave way to cigar-shaped ones, the shell became metallic - it was made of lightweight aluminum. The steam engine was replaced by a gasoline engine, and warm air was replaced by hydrogen, which was now filled with the already rigid shell of airships. True, hydrogen is an explosive gas, which caused major disasters.

The peak of airship building was 1900, when the German general, Count Ferdinand Zeppelin, began mass production of airships. They were named after their creator - zeppelins. These were giants with a large carrying capacity. In 1910, the world's first airship was built specifically designed to carry passengers.

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 ... >>

Fresh water from the seabed 03.03.2004

In the Mediterranean Sea near the French city of Menton, 800 meters from the coast, at a depth of 36 meters, a source of fresh water was found gushing from the seabed.

The existence of such underwater keys was reported by ancient authors. Now there are more than a thousand such sources all over the world. But the source near Menton is interesting in that it was first exploited to supply the city with drinking water.

For fear of disturbing the source, they did not drill it and turn it into a well, they simply put an anchored metal cap with a diameter of two meters and a height of ten, connected with a flexible hose to the surface, above it. Fresh water, as lighter, rises into the cap.

The water pressure at depth is so great that pumps are not needed. Above the surface of the sea, it beats like a fountain, one hundred liters per second. But under the cap, sea water seeps in a small amount, so a weakly mineralized drink is obtained (less than a gram of sea salts per liter). Such water is suitable for irrigating plants, but it will still be desalinated for drinking.

Meanwhile, a thousand times more powerful freshwater source was found underwater off the coast of Syria. The issue of its arrangement with the same system is being considered.
