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.

Microsoft is known not only as a Windows developer - the company has been releasing a series of branded Surface devices for years. Soon the assortment of the company’s line can be replenished with another gadget - according to the new patent application, this time the corporation will try its hand at the market of smart acoustics.
Patent documentation describes a device that is positioned as a “portable speaker.” Judging by the attached images, its body is made of plastic, and the upper part is covered with fabric. In many ways, the gadget repeats the functionality of Amazon and Google solutions - as for the voice assistant version, the corporation will probably use its own development of Cortana.
The patent indicates the presence of built-in muteable microphones, as well as volume buttons and answer calls. It is assumed that one of the functions of the device will be a speakerphone when paired with a smartphone. Separately, the removable base of the gadget's body is mentioned in the document - this design is probably intended for the convenience of attaching the column to the wall.
It is possible that the company will promote such a speaker as an addition to the equipment necessary for arranging conference rooms. The commercial name, announcement date and price of the mysterious new items have not been announced.

Dr. Eric Campert presented groundbreaking work at the British Science Festival, where he spoke in detail about the tests that were conducted in the simulator lab and on the road using 5G communications capabilities, Sky News reports.
As the researcher explained, 5G is crucial for cars driving without a driver, complementing them with a variety of sensors, providing additional information that can increase the safety of vehicles and pedestrians.
“Using this technology will allow the transfer of external information. Pedestrians do not behave like vehicles. Where there are vulnerable road users such as pedestrians, cyclists and motorbikes, the additional information provided by our technology can help, ”he told Sky News.
Thanks to the new 5G communication speeds, a team from the University of Warwick was able to transfer potentially vital data to a car without a driver almost 40 times faster than fixed-line broadband speeds allow. In practice, this means that a detailed UK satellite navigation map can be sent within one second.
