What behavior is typical for a drowning person just before the final dive?

A drowning person does not always actively resist and call for help. Often, in the last 20-60 seconds before the final dive, the sinker obeys instincts that cause him to assume an upright position, spread his arms to the sides and try to keep his mouth above the surface of the water in order to breathe. At this time, a person physically cannot scream and consciously move his arms and legs. An unprepared observer, even if he is near such a bather, does not notice anything strange.

What are the mutant genes of fruit flies called kenny and barbie responsible for?

Drosophila biologists like to give their mutant genes names that evoke popular culture. For example, a mutant gene whose owner invariably dies within two days of being infected with a particular bacterium is named "Kenny" after the character from the South Park cartoon. And a pair of genes that lead to the absence of external genitalia in males and females has been named "ken" and "barbie".

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 ... >>

The use of hands-free systems does not affect driving safety 03.01.2017

Using hands-free systems to receive calls while driving is completely legal, while holding a phone to your ear while driving is illegal in many countries. This should lead to the conclusion that various types of Bluetooth headsets are much safer, but according to a study by the Queensland University of Technology, this is not entirely true.

As part of the study, Dr. Shimul Haque measured the reaction time of drivers using hands-free technology, holding a phone in their hand and not talking on a mobile phone while driving. The test was carried out in a simulator in which each driver found himself in the same situation: a person crossing the street at a pedestrian crossing fell into the field of peripheral vision of a motorist.
As it turned out, the reaction time of drivers with and without a headset was about the same - 40% lower than those who did not have a phone at all. “In real-life conditions, this is comparable to a 11-meter late reaction for a vehicle moving at a speed of 40 km / h,” said Haq. What's more, distracted drivers were more likely to brake hard, which created concern among nearby motorists.

According to Hack, it is the cognitive load required to carry on a conversation that distracts a person, not whether he is holding a phone or not. "In other words, the human brain compensates for receiving more complete information from a mobile phone by not sending some visual information to working memory," the doctor explained. Simply put, the distracted driver looks at objects but does not see them.
