What explains the prevalence of blondes among the population of the Solomon Islands?

Approximately 10% of the black inhabitants of the Solomon Islands, which are located northeast of Australia, are blond. Previously, there were several hypotheses regarding the cause of this phenomenon, including the interbreeding of aborigines with European navigators. However, genetic analysis of the islanders showed that their blond hair is due only to a special form of the TRP1 gene. This mutation arose in the population many millennia ago and is in no way connected with the prevalence of blondes among Europeans, which is explained by the influence of other genes.

Why did the drivers of the first trucks need an assistant?

The first trucks with internal combustion engines appeared at the end of the 10th century. Of course, they were very clumsy and developed a speed of no more than XNUMX kilometers per hour. The biggest problem in designing heavy vehicles was their braking system.

Imperfect brake pads often failed, and if at the same time a not very reliable motor stopped working, then the seemingly harmless transportation of some cabinet or chest of drawers could turn into a real disaster with human casualties.

The driver needed an assistant who was sitting ... behind! The fact is that in the event of a brake failure when climbing uphill, the assistant had to stick the so-called “mountain stop”, that is, a steel stake, into the road so that the car would not roll back. It was a dangerous business to drive trucks.

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 ... >>

Chlamydomonas as a draft force 04.12.2005

Biologists from Harvard University (USA) made the single-celled alga Chlamydomonas carry heavy loads.

Algae, moving with the help of two flagella, swim towards the light. Near the light source, the experimenters placed polystyrene beads coated with a special adhesive that decomposes under ultraviolet light.

When the chlamydomonas touches the ball, it sticks to the algae. The light is turned off and a new beacon is lit at the other end of the aquarium. When chlamydomonas with a load, the mass of which can reach the mass of the cell itself, swims up to the light, they give a flash of ultraviolet light. The load is peeling off. The light is turned on again at the other end of the path, and the empty seaweed is sent for a new load.

So far, this is just an interesting experiment, but in the future, chlamydomonas may serve as assemblers of nanotechnological devices.
