Brain implant for memory recovery

21.02.2014

DARPA (US Defense Advanced Research Agency) has begun developing new methods for analyzing and deciphering neural signals in order to understand how neuronal stimulation can be used in the process of recovering the memory of a person who has suffered a brain injury. For this, it is planned to develop an implant that will help in the treatment of memory disorders using neural stimulation. The project was called RAM (Restoring Active Memory - restoration of active memory).

According to the agency, between 2000 and mid-2012, there were 250000 cases of brain injuries in the US Army. Such damage often leads to memory impairment, which includes both the loss of memories formed before the injury (amnesia) and the inability to retain new ones in the head. In other words, we are talking about post-traumatic memory impairment.

DARPA is going to create a brain implant that can stimulate neurons to reduce or even completely cure these memory disorders.

The neural stimulation method involves the use of devices that send electrical discharges to the brain. It is already used in the treatment of disorders such as epilepsy and Parkinson's disease. Another way to use this device could be to stimulate certain areas of the brain during the training of soldiers. This can help them learn new skills faster, sharpen their reflexes, and better control their emotions. Recent advances in neuroscience have shed light on the mechanisms that are involved in the process of learning and applying existing knowledge and skills.

The program includes the development of complex memory models and consideration of the neurobiological and behavioral differences between implant-assisted memory and natural learning. Among the candidates for a partnership with DARPA is Medtronic, which is known for creating a deep brain stimulation implant that almost magically reverses the effects of Parkinson's disease.

It is not known how soldiers will react to DARPA innovations, but they can have very interesting results in medicine, for example, in the treatment of Alzheimer's disease.

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, ... >>

Robotic chemist of the future 06.02.2024

Specialists from the University of Amsterdam presented RoboChem, an artificially intelligent robot that opens a new era in chemical synthesis, surpassing the speed, accuracy and innovation of even experienced chemists. RoboChem uses machine learning technologies to transform chemical synthesis processes, unlocking new molecular capabilities and replicating existing research.

RoboChem opens new perspectives in chemical synthesis, providing more efficient and innovative methods for studying molecular structures and developing new materials. Its ability to learn and analyze data will make it a valuable tool in research and industry, contributing to the future of chemical science and technology.

The principle of "flow chemistry" allows RoboChem to replace traditional laboratory glassware with a compact network of small test tubes. It precisely doses reagents, which are then processed in a reactor illuminated by LEDs to catalyze molecular transformations. The results are analyzed using automated NMR spectrometers, and the data is processed in an artificial intelligence system for in-depth analysis.

RoboChem has demonstrated consistently better results than traditional chemical synthesis methods, achieving successful yields in 80% of cases. It identifies reactions with minimal expenditure of resources, sometimes exceeding the expectations of human chemists. In addition, the robot collects extensive data, including both successes and failures, providing a valuable source of information for future AI-driven chemistry research.
