The new precision record for atomic clocks belongs to a team of scientists at the Massachusetts Institute of Technology working on the phenomenon of Quantum entanglement based method to have used a to create super accurate device. The performance and work is described in an article published in Nature.
Structures that are generated by gravitational interactions in the solar system enable objects to move quickly in space - scientists inform. The newly discovered route network can be used for your own space exploration.
Scientists have discovered a previously unknown network of cosmic "highways" that allow us to travel through the solar system much faster. Such routes could allow comets and asteroids near Jupiter to reach Neptune in less than a decade. You can have up to 100 astronomical units travel in less than a century. Newly discovered routes can be used to send spacecraft relatively quickly into the most remote corners of our planetary system and to observe and understand objects that could collide with our planet.
At present, work is being carried out on several tracks to improve the efficiency of many different techniques for generating solar energy. The researchers have succeeded in the novel Perovskite silicon tandem solar cells to achieve an efficiency of almost 30, more precisely 29,15%. This is another record in the category.
A Spanish working group has found a way to generate a spatially limited magnetic field at some distance from the source. The team around Rosa Mach-Batlle from the Universitat Autònoma de Barcelona uses cylindrical arranged, current-carrying wires that form a magnetic metamaterial. The control of magnetism, which is essential to a wide variety of technologies, is compromised by the impossibility of achieving the maximum Magnetic field to generate in free space. Here the researchers propose a strategy based on negative permeability is based to overcome this severe limitation. They demonstrate experimentally that an active magnetic material can emulate the field of a straight electric wire at a distance. Their strategy leads to an unprecedented focusing of magnetic fields in empty space and enables the remote erasure of magnetic sources, which opens a way to manipulate magnetic fields in inaccessible regions.

A team of Chinese scientists has one quantum computers which, according to its authors, demonstrates the superiority of quanta. The advantage of the Jiuzhang calculator manifests itself in the computing speed. According to the Chinese research team, it took their quantum computer just 200 seconds to perform calculations that would take the fastest conventional computer millions of years to do.
Last October, Google officials confirmed an earlier media report on achieving quantum supremacy. The Sycamore computer they created seemed a long-awaited breakthrough in the Quantum computing to be. Google engineers reported that their quantum computer solved a problem in just over three minutes that would take even the best conventional machines thousands of years to solve.
Quantum computers can far outperform conventional machines. The goal is the so-called "Quantum SupremacyThe Sycamore computer only achieved this advantage in one very specific case. The experiment by Google engineers consisted in performing random operations on qubits and reading the result. The resulting sentence of digits encoded in a binary system has been checked to ensure that their distribution is really random.These calculations are not particularly useful, but they have a major impact on the computing power of the device.
A new material can help build quantum computers. Superconductors are materials in which electricity flows without encountering resistance. Usually its path is one-way, but a material has been discovered in which current can flow in two directions at the same time. Science (https://science.sciencemag.org/content/366/6462/238)
This unusual superconductor is the so-called b-Bi2Pdwhich is made up of crystalline bismuth and palladium. If we form a ring from a thin layer of material, it turns out that the current in it will flow clockwise and counterclockwise at the same time. The discoverers of the phenomenon predict that it will be used in the next generation of quantum computers, thanks to the direct use of the laws of quantum physics will be able to perform calculations much faster than their modern counterparts.

An astrophysicist from the University of Bologna and a neurosurgeon from the University of Verona compared the network of nerve cells in the human brain with the cosmic network of galaxies. These analyzes show that the structures of the observable universe are surprisingly similar to the neural networks in the human brain. Research suggests that the laws governing the development of the brain and the cosmos could be the same. One of the fascinating peculiarities of the world around us is that different shapes and patterns appear in very different contexts. For example, the golden spiral (the Fibonacci spiral) is found in a snail shell and in the shape of a spiral galaxy, and the vein pattern echoes in a branch of lightning.
Today again out of line: Star Trek sends its regards. Some of you will remember Star Trek episodes in which the term "weather control station" was used. Australian physicists have developed technology that might be able to control lightning to some extent. Scientists have used the laser beam to change the lightning path in the laboratory, but believe their work can be successfully applied in natural conditions. This could allow them to change the point of impact on the ground, reducing the risk of catastrophic bushfires. While weather control technology seems torn straight out of science fiction books and films, scientists are looking for similar solutions. Research has already produced tangible results in the form of a laser beam that can prevent lightning, which can lead to catastrophic fires and destruction.

Lightning strikes are the number one natural cause of bush fires in Australia and an increasing number of fires in the United States. For example, a laser that can influence the lightning path has the potential to save lives, protect wild animals and large areas of the natural ecosystem.
Scientists have developed a white color that reflects so much of the sun's rays that it can cool the walls of buildings below the ambient temperature in full sunshine. The new invention is cheap and can be produced with common technologies. Researchers are already finding dozens of uses for this remarkable color, though it will take some time to get to market. The new super white color reflects 95,5 percent of the sunlight. The technologies used so far made it possible to obtain a color that reflects about 80-90 percent of sunlight. So far, however, no paint has been able to bring the temperature of a building below the ambient temperature.
