Birds can see magnetic fields

05.09.2018

Scientists have put forward an unexpected hypothesis that explains why birds do not go astray during migrations. Perhaps they have the ability to see the Earth's magnetic fields.

Ornithologists have concluded that birds provide supervision with a special protein. The protein is called Cry4 and belongs to the class of cryptochromes, which are responsible for the ability to recognize blue and ultraviolet colors and affect the regulation of circadian rhythms. They are found not only in animals and birds, but also in plants.

Swedish scientists from Lund University have found that this protein may be associated with the ability to feel and see the planet's magnetic field.

The scientists also found that migratory birds have much more of this protein than those who live in the same region all year round.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

31" monitor LG 31MU95 with a resolution of 4096x2160 pixels 20.12.2013

LG has announced that at CES 2014 in early January in Las Vegas, the new UM21 and UB9 series ultra-wide (65:65 aspect ratio) monitors will be showcased. The first series is aimed at home users, while the design and equipment features of the second series (for example, height adjustment and support for the pivot function) make them suitable for office use.

Both series will be represented by models with a diagonal of 25, 29 and 34 inches. They will use IPS-type LCD panels with a resolution of 3440 x 1440 pixels.

Among the new products will be the UM95 series monitors, represented by two models: 34-inch and 29-inch. Their feature is the support of Thunderbolt 2 and DisplayPort 1.2 interfaces. It is also reported that the UM95 line of monitors will cover 99% of the sRGB color space.

The real highlight of the new LG monitors will be the 31MU95 model with a 31-inch IPS LCD panel with a resolution of 4096 x 2160 pixels and an aspect ratio of 16:10.
