In Ukraine, a functional electronic hand prosthesis was developed.
This is reported by Facts.
Anna Belevantseva from Kiev, a member of the Ukrainian startup team that created her own bionic prosthesis, said: “The need for such prostheses is great. Two years ago, we set ourselves the goal of creating a modern bionic prosthesis that would be much cheaper than foreign ones and surpass them in its characteristics. And now the prototype is fully ready for clinical trials. Based on their results, in about a month we plan to present a prosthesis ready for use. It was created by a team of five people. "
About what happened, Anna said this: “The team of our engineers had a chance to create a more advanced prosthesis - using the most advanced technical innovations. They coped with this task. They achieved, for example, that each finger of the prosthesis can move independently (this is not the case in competitors' models). At the same time, the cost of our product is from six to twelve thousand dollars. That is, more than four times cheaper than competitors.
It is important to note that we regularly consult via Skype or phone with prosthetists from the USA, Canada, Poland. And also with their Ukrainian colleagues and doctors with experience working with patients who have bionic prostheses. In Ukraine, they provided approximately 15 ATO veterans. ”

The American corporation Boeing has successfully completed the first test flight of the unmanned aerial tanker MQ-25 Stingray. This was reported by the press service of the aircraft company.
The MQ-25 test facility, known as the T1, performed an autonomous two-hour flight under the supervision of Boeing test pilots flying from a ground control post at MidAmerica St. Louis Airport in Muscat, Illinois, where the test program is based. The aircraft completed autonomous taxiing and take-off, and then flew along a predetermined route to verify the basic functions of the flight and operations with the ground control station.
The MQ-25 will provide the Navy with much-needed unmanned aerial refueling capabilities on the basis of an aircraft carrier. This will expand the flight range of the air carrier wing.
T1 received its FAA pilot certificate of airworthiness in September, certifying that the aircraft meets Agency requirements for a safe flight. Testing will continue with T1 for further early exploration and discovery, which promotes core systems and software development.

Japanese scientists introduced the first probabilistic computer.
Engineers from Tohoku University of Japan and Purdue University of America introduced the first device that works on a probabilistic computer circuit. About it writes Science Daily.
Modern computers usually store information in a sequence of zeros and ones. It is believed that in the coming years a computer of the future may appear that will use quantum bits - qubits. They can simultaneously be both zeros and ones: this approach can increase the power of computers many times.
A probabilistic computer is considered the gap between classical and quantum. The device works with probability bits - "p-bits", which can be either zero or one, at any time.
At the same time, pi-bits work at ordinary room temperature, like any classical electronics.
The first device of a probabilistic computer was the version of magnetoresistive random access memory (MRAM), which is used in some types of computers to store information. It was connected to a transistor to create a three-terminal device, the fluctuations of which can be controlled.

Chinese engineers have created technology for remote recognition of a person by drawing veins on his arm.
Engineers from the Chinese company Melux have developed a technology for remote recognition of people by a unique pattern of veins on his hands. Researchers believe that in the future, the system will replace facial identifications and QR codes, writes Zhongguo Xinwenwang.
The technology is called AirWave. At the beginning of the work, artificial intelligence using a camera captures the pattern of veins and capillaries on the user's hand. Researchers claim that the pattern of veins is unique to each person, and remotely read it easier than a fingerprint.
To pass the identification, the user just needs to wave his hand - while the system is able to determine the pattern of the hand and compare it with the person’s personality in a few seconds, the developers say.

Magnets are a fairly common type of material with special magnetic and electrical properties - and regardless of the shape of the magnet, they are all one way or another made of solid material. However, a team of chemical engineering specialists from the University of California was able to create an unusual liquid magnet based on unique 3D printing technology and an equally unique approach to creating liquid nanoparticles based on ferrofluids. As a result, scientists turned out to be a real liquid magnet with similar properties of magnets.
More precisely, the properties of the new liquid magnet are such that they can be easily changed by applying any traditional magnet made of solid material to the new type of magnet - thus changing the properties of one magnetic field using another. As for the development itself, the scientists first conducted an experiment with ferro-fluids - a special type of fluid-solutions containing iron oxide particles, and managed to create an improved solution in which iron nanoparticles were placed.
After completing the additional stabilization step, they also conducted additional studies and found out that to create liquid magnetic droplets they need to ensure strong bonding of the nanoparticles to each other even at the smallest possible size indicator. This resulted in the development of a conceptually new 3D printing technology, which offered the possibility of organizing liquid magnetic droplets of less than 1 nm in size, which is really an impressive indicator, given that the ferro-liquid solution has an unstable character in one way or another.
As a result, scientists have proposed a conceptually new approach to the creation of a liquid magnet, which can change the degree of its magnetic properties and shape depending on what needs to be done in a given time interval. In addition, the new magnetic design clearly demonstrates that printing has some additional features that can be further improved and brought into line with additional materials.
