How are hedgehogs used to count ticks?

Hedgehogs collect more ticks for their quills than any other animal. The same spiny cover prevents hedgehogs from getting rid of ticks. Specialists-parasitologists even began to use hedgehogs for quantitative accounting of ticks in natural foci of encephalitis and introduced a special unit of account "hour-hour", meaning the number of ticks collected by a hedgehog on itself in one hour of running through the forest.

How many horsepower can one horse develop power?

When James Watt marketed his steam engine, he needed to visualize its superiority over conventional energy sources. He calculated how much, on average, per minute an ordinary horse lifts by driving a water pump, and designated this unit of power as horsepower. Then the power of steam engines, expressed in horsepower, immediately began to indicate how many times the machine is more efficient than a horse. By the way, according to the calculations of scientists, for a short time a horse can work with a maximum load of almost 15 horsepower.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Grazing robot 30.11.2015

Water bugs are little known to the masses. They are mainly herbivorous and live in ponds or slow-moving rivers, where they swim with paddle-like hind legs covered with hairs. This feature gave rowers in the United States the name "river boatmen" (water boatmen).

However, for scientists at the University of Bristol (Great Britain), rowers served as a source of inspiration for the creation of a new type of device for water purification from microorganisms. A prototype robot called Row-bot (a play on words from the English row - “row”) moves along the surface of polluted ponds and lakes, collects microbes, “eats” them and “digests” them in an artificial stomach, thereby generating energy to ensure its life.

The Row-bot consists of two main components: a paddle-shaped propulsor driven by a miniature 0,75 W DC brushed motor, and a "stomach" containing microbial fuel cells that generate electricity. When it enters a body of water, the robot absorbs a certain amount of liquid with microbes, and the elements generate electricity sufficient for several strokes. The robot starts moving, "drinks" more water, and the process repeats. In this, Row-bot differs from similar miniature floating robots, as it is completely powered by the environment in which it floats. For example, the "Robo-bee" (Robobee), invented by the staff of Harvard University, which we recently wrote about, provides itself with power through piezoelectric actuators.

As for the rower, the developers borrowed legs from it, covered with hairs to increase the surface area during the traction phase of the stroke. The legs then fold in to reduce water resistance. Each paddle paddle is 3D printed from composite materials and is a rigid frame supporting an elastic membrane. A loop is built into the membrane, which changes the angle of attack of the part of the oar that is under water, and thereby further reduces the resistance of the water.
