Kite received a bionic prosthetic leg

22.06.2021

A team from the Medical University of Vienna, led by Professor Oskar Asmann, has made another breakthrough in the field of bionic devices. Experts managed to replace the lost paw of a lamb kite named Mia, a representative of the largest birds of prey in Europe. He became the first bird in the world with such a complex prosthesis.

Kite Mia arrived at the Austrian Owl and Birds of Prey Nature Reserve in Haringsee with a badly damaged leg that had to be amputated. The phenomenon is not so rare, and for small birds with a symbolic body weight it is not difficult to learn how to get by with one paw. In the case of Mia, everything is exactly the opposite - a huge and heavy bird will not even be able to land properly after a flight without having a reliable support on two paws.

Therefore, it was decided to conduct an experiment on osseointegration, when the prosthesis is mounted directly on the rest of the bone and subsequently grows into it. As a result, scientists went even further - Professor Asmann has already installed three biomechanical prostheses with the control of mental impulses in people, and decided to try to do the same with a kite. Everything turned out great, Mia began to walk three weeks after the operation, and by the sixth week she had already learned to fully transfer her body weight to the prosthesis.

Of course, such a simple prosthesis will not replace a real paw in every sense, but it is much more perfect than primitive models. Osteoporception technology assumes that the creature eventually develops a natural connection with the device, and begins to use it as if it were "native", without discomfort to itself.

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 ... >>

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, ... >>

Graphene will be used in a quantum computer 04.01.2014

The amazing material graphene is now the object of study in many laboratories around the world. Researchers at the Massachusetts Institute of Technology (MIT) have uncovered additional potential for using a single layer of carbon material, discovering unexpected properties it exhibits under certain conditions. According to experts, these properties can be used in quantum computing.

As it turned out, under the influence of a very strong magnetic field and a very low temperature, graphene filters electrons along the spin - the electronic devices we are used to are deprived of this quality.

If you apply voltage to a piece of graphene under normal conditions, a current will flow through it. However, as soon as a magnetic field is applied, the lines of force of which are perpendicular to the plane of graphene, its behavior changes: the current flows only along the edge of the piece, and the central part becomes a dielectric. Moreover, the current flows in only one direction, depending on the direction of the magnetic field lines. This effect is known as the quantum Hall effect.

The researchers took the next step by applying a second magnetic field parallel to the graphene sheet, and this again changed its behavior. Electrons were able to move in both directions, with positive spin electrons moving in one direction and negative spin electrons moving in the opposite direction.

Spin segregation of electrons is characteristic of topological insulators, but it is not observed in conventional conductors. According to the scientists, they managed to create a special kind of conductor by making one material behave like another. Moreover, by changing the magnetic field, it is possible to control the detected edge effect. As stated, this principle can be used to build transistors and more complex circuits that have not yet been possible to implement using existing materials.

In particular, scientists see the potential of graphene in relation to the creation of a quantum computer in the discovery. Of course, the effect is still far from practical application: it is observed at a magnetic field induction of 35 T, which is approximately an order of magnitude greater than in MRI, and at a temperature that is only 0,3°C above absolute zero.

However, scientists have already managed to detect a similar effect in a field with an induction of only 1 T and at higher temperatures.
