A group of researchers from Imperial College London and Samsung have created a neural network that can “liven up” a photo of a person by putting a recording of his or someone else’s voice on it.
According to The Verge, the algorithm developed by scientists is still far from perfect, since the mimicry of people on the videos it generates is not entirely natural. However, the results of the neural network are still impressive, considering how little data the program needs to create such fakes. To demonstrate the operation of the algorithm, its creators put a recording of Albert Einstein’s voice on his photograph.
Less fortunate is Grigory Rasputin, who in the processed video performs the song Beyonce.
Development confirms that fake video technologies are rapidly developing. It is safe to assume that in the foreseeable future, users will have access to simple programs that generate similar or more sophisticated fakes that can be used to promote or discredit specific people.

Researchers at the University of Texas at Austin have created an “electronic tattoo” that attaches to the patient’s chest, which can replace traditional ECG devices (electrocardiography).
This is the portal Eurek Alert.
According to the National Center for Health Statistics, the main cause of death in Texas is heart disease, which in 2017 accounted for more than 45,000 deaths across the state.
A new wearable device is created from graphene and piezoelectric polymer of polyvinylidene fluoride, which generates electricity in response to mechanical stress. This technology can make monitoring heart health easier and more accurate than existing electrocardiographs, which have changed little in almost a century.
The research team reported on their newest electronic tattoo in a recent issue of Advanced Science.
The device is so light and stretchable that it can be fixed in the area of the heart for long periods, almost without feeling discomfort. It measures the work of the heart in two ways, simultaneously reading the indications of the electrocardiograph and the seismic cardiograph.

Most of us are familiar with the electrocardiogram (ECG), a method that records the levels of electrical activity that occurs with each heartbeat. Seismic cardiography (SCG) is a method that measures chest vibrations associated with heartbeat. "Electronic tattoo" is remotely controlled by a smartphone, is the first ultra-thin and flexible technology that allows to measure ECG and SKG.
"We can get a much deeper understanding of heart health through the simultaneous collection of data from both sources," said the head of the research group Lou, an associate professor at the department of aerospace engineering and mechanical engineering and biomedical engineering.

Amazon has patented a system for using drones-suppliers of goods as surveillance cameras for security.
About it on Friday, June 21, writes the edition The Verge.
The company filed a patent application in June 2015, but received it only in 2019. The document states that users will be able to hire Amazon drones in particular to monitor their homes and inform, for example, about open doors, broken windows, graffiti and even fires.
Amazon says they are hoping to launch a commercial service for several months.
Customers will be able to order hourly, daily or weekly visits to drones. Unmanned vehicles can be equipped with night vision cameras and microphones.

Scientists from the National Laboratory of High Magnetic Fields (National High Magnetic Field Laboratory, MagLab) of the University of Florida set a new record for the strength of a permanent magnetic field generated by a new electromagnet with superconducting windings. In the same laboratory, there is also the previous owner of this record, an electromagnet that generates a field with a force of 45 Tesla, and a new electromagnet produces a field with a force of 45.5 Tesla. This is not like a huge breakthrough, however, this achievement opens the way to the creation of even more powerful magnets based on the use of the phenomenon of superconductivity.
Note that scientists have long been creating strong magnetic fields with the help of inductors, called solenoids. When an electric current passes through the coil windings, it creates a magnetic field. An increase in the strength of the current flowing through the windings leads to an increase in the generated magnetic field.
The electromagnet, producing a field of 45 Tesla, was the most powerful DC electromagnet for nearly two decades. This device was the key one around which all activities of MagLab specialists were concentrated, but in this laboratory there is also another magnet with windings “having electrical resistance”, roughly speaking, a copper coil producing a magnetic field of 33.6 Tesla. The windings of this magnet transmit a power of 31 MW, and in order to divert the released heat from them, it requires the pumping of thousands of liters of pre-cooled water.
Created in the laboratory MagLab new electromagnet was named “Little Big Coil 3”, its size in the assembled state does not exceed the size of a beer glass. Its superconducting windings are made from a non-traditional alloy of tin and niobium, instead a new material REBCO (rare-earth-barium-copper-oxide) is used, which becomes superconducting at a higher temperature. The thickness of the tape of this material does not exceed the thickness of a human hair, which allows for very dense winding. In addition, scientists have replaced the insulating material with a new material that does not affect the superconductivity of the windings and does not distort the generated magnetic field. All this set of measures allowed to increase the current density in the windings and to obtain a record strength of the field generated by them.
Note that such strong magnetic fields are used in basic scientific research, such as the study of the properties of new materials. The real value of this achievement is not at all in the practical use of the new magnet, the new materials and technologies used in its creation can be used to create new reliable and powerful facilities that will allow for previously impossible experiments and research.

Samsung has patented the first laptop with sliding walls
Famous Korean manufacturer of equipment Samsung is preparing to release the first of its kind laptop, the screen of which will expand as needed, creating additional space for work or watching movies
So, a laptop with a non-permanent screen will be called Galaxy Fold and will repeat the latest features of the latest Samsung smartphone, which can “push” the walls of its screen. The design was patented on December 19 last year, and patent documents were published in June of this year, reports itech.
It is noted that in the folded state, the aspect ratio of the novelty is 16: 9, and its increase reaches 50%. At the same time, it is not known how exactly the aspect ratio changes after the inclusion of a special function. In the manufacturing company only indicated that it will be more. Than 21: 9, but a little less than 32: 9.
The super-wide screen is suitable for working behind a laptop, for playing games, and for watching movies. When the laptop screen is decomposed, it remains supported by a metal frame that moves with the screen parts to the side, that is, the screen is protected from damage.
Earlier it was reported that Samsung may soon release a smartphone with two screens. They have already received a patent for this gadget. It is reported that the second is located on the back of the smartphone. It can be used for selfies.
This arrangement gives manufacturers the opportunity to opt out of an anterior chamber or sliding mechanisms. At the same time, the main screen can occupy one hundred percent of the front panel area.
The patent was obtained quite recently, on June 11, 2019. Interestingly, the patent was issued by the US Patent Office, and not by the South Korean equivalent. Therefore, we can conclude that the smartphone will appear on the market very soon.
However, it is worth remembering that companies like Samsung annually register thousands of patents, and almost all of them do not get to mass production. So you can stake out a certain technology behind you, and if anyone else wants to use it, get a percentage of the technology license.
