From whom did the Tibetans inherit the genes that make life easier in the highlands?

The Tibetan genome contains an allele of the EPAS1 gene, which increases the presence of hemoglobin in the blood, which explains their adaptability to life in high mountain conditions. No other nation has this adaptation, but exactly the same allele was found in the genome of Denisovans - people who do not belong to either Neanderthals or Homo Sapiens. Of all the hypotheses, the most probable is that many thousands of years ago the Denisovans interbred with the common ancestors of the Chinese and Tibetans. Subsequently, the Chinese living on the plains lost this allele as unnecessary, while the Tibetans retained it.

Random interesting fact from the Great Encyclopedia:

Why is Antarctica the highest continent on Earth?

The average height of the indigenous (subglacial) surface of Antarctica is only 410 meters, while the average height of the surface of all other continents is 730 meters.

Nevertheless, it is Antarctica that is considered the highest continent on Earth. But the fact is that Antarctica is covered with an ice shell, the average height of which is 2040 meters (2,8 times the average height of the surface of all other continents).

Near the South Pole, the thickness of the ice shell reaches 3800 meters. The total mass of frozen water concentrated in Antarctica is 30 million cubic kilometers. Under its weight, the earth's crust on this continent sagged up to 950 meters.

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 ... >>

New digital potentiometers 24.06.2005

INTERSIL announces the launch of the new ISL90460, ISL90461 and ISL90462 digital potentiometer family, the world's smallest 32-pin potentiometers.

They are designed to adjust contrast and brightness in mobile phones, personal digital assistants and GPS receivers. The resistance range of the new potentiometers is from 10 kΩ (available in a 5-pin SC-70 package) to 100 kΩ (available in a 6-pin SOT-23 package).

The supply voltage of the new potentiometers is from 2,7 to 5,5 V. Microcircuits are produced using lead-free technology.
