What animal does the third eye help to navigate in space?

The third eye, or parietal eye, is a common photosensitive organ in some jawless animals, fish, amphibians, and reptiles. It is located between the main eyes and is much smaller than them in size, and is also tightened with skin, albeit more transparent. It has a retina, a nerve, and an analogue of the lens, which allows you to perceive the direction of sunlight, the polarization of light from the sky, and, according to some hypotheses, the lines of the Earth's magnetic field. For many species, the need for a parietal eye for normal orientation in space has been experimentally confirmed. In birds and mammals, only the pineal organ remained from the third eye - the so-called pineal body, which is part of the endocrine system.

Which waterway in the US connects two oceans?

The Panama Canal is not the only waterway connecting the Atlantic and Pacific Oceans. There is a stream in Wyoming that splits into two streams. The first goes west to the Pacific Ocean through the Snake and Columbia Rivers, and the second goes east to the Atlantic through Yellowstone, Missouri and Mississippi. The ship will not pass through this stream, but the fish may well migrate.

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, ... >>

Water purification with brewer's yeast 18.08.2019

Brewer's yeast and other beer waste can reduce nitrate levels in Spanish waters by up to 40%. This conclusion was made by scientists from the Spanish Center for Advanced Studies Blanes (CEAB-CSIC).

Beer production waste contains microorganisms that process nitrates into molecular nitrogen.

Nitrates are a serious pollutant of European rivers: because of them, the level of oxygen in the water decreases, which affects the underwater flora and fauna. So far, there is no technology that would allow removing nitrates from water at water treatment plants.

Scientists are already testing the effectiveness of their method in several ponds and dams in Barcelona. If this cleaning method proves effective, it will be used in other regions of Spain, especially where agriculture is developed - the main source of nitrates.
