Nanobots to be launched into human veins

30.07.2016

Researchers at Drexel University have demonstrated how an electromagnetic field can be used to make tiny robots move faster in a liquid medium. Scientists plan to use these devices in the future to deliver drugs through blood vessels.

Nanobots are chains of tiny round particles. The magnetic field rotates the particles, like a screw, while the longer the chain, the greater the speed it can develop. The scientists tested various robots, starting with strings of three "beads". The longest device consisted of 13 particles and reached a speed of 17,85 micrometers per second.

In order for the robots to move, an external magnetic field was applied. The faster the rotation speed of the field, the faster the chains moved. At the same time, the high frequency led to the division of long devices into shorter ones. So, a robot of seven beads, upon reaching a certain speed, begins to deform and is divided into two chains of three and four particles. The direction of the magnetic forces can be changed so that the two robots move in opposite directions.

The chains can be modified to serve as a drug delivery system as well as perform various tasks during surgical procedures. For example, robots can clean veins and arteries blocked by clotted blood cells or cholesterol plaques.

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, ... >>

Neuromorphic chips for artificial intelligence 02.08.2013

Artificial intelligence excites the minds of mankind for more than half a century. Millions of works have been written on this topic and hundreds of films have been made. Modern philosophers, psychologists and sociologists are trying to predict, or even just give their opinion about how a machine will behave when it becomes fully conscious.

At the same time, most scientists are inclined to believe that at this level of technical development, using modern technologies and electronics based on silicon, it is impossible to create artificial intelligence. Hopes are pinned on quantum electronics, but it is still in its infancy.

Be that as it may, Swiss scientists from the University of Zurich, together with scientists from the Higher Technical School of Zurich, as well as colleagues from the USA and Europe, managed to create neuromorphic chips that, when connected to a network, are able to imitate some of the cognitive processes of the human brain. Scientists have succeeded in getting such AI to perform complex tasks that require context-sensitive decision-making and short-term memory, which, according to scientists, only primates are capable of besides humans.

Of course, this does not mean that in a few years humanity will learn how to create intelligent machines, but we have become one step closer to this.
