Everything goes to the fact that in the near future in order to control any electronic device will not have to touch that device directly. This will be possible thanks to the many technology of recognition of movements and gestures, based on optical, acoustic and other methods. A contribution in this direction was made by Google in the project Soli, developing and making prototypes of miniature radar-on-chip, capable of very high accuracy to track the movement of the hands and fingers of a person.
When the surgeons are trying to reach the organs of the human body, which are located in remote places, they are forced to make numerous additional incisions and special instruments called retractors, in order to gain access to the area at different angles. However, a group of researchers from Italy, working in the framework of the European project STIFF-FLOP, has developed an alternative - a flexible tool, which is based on the structure of the tentacles of an octopus. With its high flexibility, mobility and ability to lock the tool can penetrate into the region of the operation, gently lift the bodies and hold them in position, freeing the surgeon to perform other complicated manipulations.
An international group of physicists, led by Hirosi Ooguri (Hirosi Ooguri) from the University Kavli, Tokyo, and mathematicians from the California Institute of technology made a significant step towards the unification into a single unit of General relativity and quantum mechanics. The work of scientists, which will soon be published in Physical Review Letters, brings a new fundamental basis for the so-called Theory of everything (the Theory of Everything, ToE), describing how the space-time continuum is formed on the basis of the phenomenon of quantum entanglement.
In recent years quite actively conducting research and development towards creating a flexible, wearable electronics, is able to transform into wearable digital device things people or everyday objects. But progress in this direction is still very mediocre for several reasons, and primarily due to the fact that the current electronic technology is quite cumbersome and inconvenient in order to integrate them into clothing, giving, thus, inconvenience to their owners.
American scientists involved in the development of various military equipment, has developed and manufactured a pilot batch of miniature unmanned aerial vehicles, each of which fits in the palm of the hand. The drone, called Cicada (Cicada), according to its developers, is something like "mobile phone with wings". Numerous swarm of these drones being fired at a higher elevation from the plane, will land on the surface exactly at the specified location, performing along the way and after landing tasks with the built-in electronic unit of the sensor types.
Recombination of electron shells of atoms of a single molecule, a process that takes several tens of attosecond (billionth of a billionth of a second), can be viewed "live" through the collaborative work of scientists from the Moscow Institute of physics and technology (MIPT) and their colleagues from Switzerland, Denmark and Japan. In recent years, scientists from different countries have made great strides in the study of ultrafast processes at the level of individual atoms and molecules, and further research in these areas can produce results that will have a huge impact on the further development of modern science and technology.
Quantum computers, which today is more a theoretical concept than a practical in the future will be able to calculate such a complex mathematical models that have very long would be too tough for even the most powerful modern supercomputers. Calculations of such models can bring to a qualitatively new level in many areas of science, including chemistry, biology, materials science, etc., But the development of quantum computing technology is hampered by the fact that scientists and engineers are simply unable to provide for manipulation of a large number of quantum bits, qubits, which is stored and processed quantum information.
A Group of researchers from the University of California (University of California) and the University stone brook (Stony Brook University) have produced the world's first chip-on-chip which created a neural network consisting solely of memristor. The memristor is the fourth basic electronic component, a kind of analog memory cell, which according to the principles of their work is the closest electronic analog of neurons and synapses. It is on these components, it becomes possible to create computers which imitates the work of the human brain and which, by their nature, will be able to quickly self-learn and to solve problems that are difficult to solve on conventional digital computers.
In this world there are many ways of creating holographic images, and each of these methods has its own advantages and disadvantages. In some methods, is able to create high quality images, used expensive materials and specialized devices, and cheaper ways to obtain images of poor quality. Trying to combine the impossible," researchers from National Taiwan University (National Taiwan University, Taipei, has developed another technology to create holographic images. The basis of this technology is a complex material, metamaterial-based aluminum nanostruc a certain height, which allows you to get a colorful image, which can have all the colors of the visible spectrum of light.
On 5 and 6 June 2015 the Office of advanced research programs of the Pentagon DARPA will conduct the finals of the famous competition Robotics Challenge (DRC). In this final, the prize Fund is $ 3.5 million U.S. dollars and which will be held at the Fairgrounds Fairplex in Pomona, California, 25 teams from different countries come together to fight for first place with the help of robots, focused on the implementation of various tasks in areas of natural disasters or man-made disasters.
The Magnetic field permeating the Earth and the entire Solar system, quite easily penetrate through matter. Therefore, the creation of an area of space completely devoid of a magnetic field, is quite a challenge. Nevertheless, the international group of physicists have managed to develop a magnetic barrier, which is more than a million times weakens even the most low-frequency magnetic fields. Using this technology, scientists have created a region of space in which there is a magnetic field, whereby it is impossible to measure even the most high-precision instruments. And in this space will be conducted scientific experiments and measurements which require the absence of any extraneous fields.
Specialists known defence company BAE Systems, in collaboration with scientists from the University of Birmingham (Birmingham University), are working on a prototype of a new information system, which will be brought to fully operational status over the next few years. Taking advantage of this virtual reality systems, the command of the armed forces will be able to manage the conduct of military operations in real time in a whole new way that is very reminiscent of futuristic technology, familiar to us on the famous sci-Fi film "minority report /Minority Report".
Friday, 8 may 2015, the European Space Agency (ESA) started a new phase of the attempt to establish communication with the module Philae, which made an unsuccessful landing on the surface of comet 67P and "fell asleep", completely exhausted charge their batteries. Currently the core of comet 67P, which is known under the name of comet Churyumov-Gerasimenko continues to approach the Sun and is at a distance of 360 million kilometers from Earth. As it approaches our sun, the temperature on the surface of the comet's nucleus steadily increases and increases the intensity of sunlight, which increases the chance that the solar cell module will be able to produce energy in sufficient quantity for "awakening" of the device.
In severe cases, where the vein or artery as a result of any disease blocks the flow, the only solution is to replace the affected part of a blood vessel another part of the vessel is withdrawn from the patient's body in another, less important, or withdrawn from the body of a suitable donor. However, now as a substitute can be a part of the artificial blood vessel made using the technology of three-dimensional printing of a special polymer material, developed by scientists from the Vienna University of technology (Vienna University of Technology) and medical University of Vienna (Medical University Vienna). Moreover, synthetic polymer made from artificial blood vessel, begins to turn into living tissue immediately after its introduction into the patient.
Physicists at mit have developed and manufactured a new portable sensor that fits on a standard desktop that is able to identify individual electrons, the cloud which exists in the environment radioactive gas. When the atoms of a gas, krypton, decompose, they emit electrons, beta radiation, and it is available in the sensor strong magnets luring these electrons in the "bottle" trap, where they are very weak radio emission is detected by a highly sensitive antenna, is amplified and converted into digital form. The collected data sets that are processed by specialized algorithms that allow to get a full picture of the processes at the level of individual electrons within a few milliseconds of time.
