A new stage in the development of artificial neurons and synapses has just been crossed. European and British researchers have in fact managed to connect biological and artificial neurons and have them communicate via the Internet. An important advance As advanced as the supercomputers are, they are still far from competing with the human brain. The latter is in fact made up of neurons which communicate with each other by pulses of electrical signals, passing…

– andrey_l / Shutterstock.com Some theories confirm that time passes more slowly in space rather than on Earth. It seems that space itself makes time slow when you take a special trip at a very high speed. The notion of time and space obeys several often inexplicable physical laws which require observation, reflection, analysis and demonstration. Einstein, Newton and Maxwell, the great physicists sought to understand space-time by exposing each of the analogical theories. But…

American scientists have developed a prototype DSL-based system that could theoretically provide a speed of 10 terabits per second, when the optical fiber peaks at “only” 10 gigabits per second. Explanations. A DSL-based system with phenomenal speed This radical leap would be made possible by switching to an extremely high frequency for data transfer, which would compress a greater bandwidth, therefore a larger volume of data, within the same space, and thus increase the overall…

– lev radin / Shutterstock.com Physicist and entrepreneur Stephen Wolfram has just launched a major challenge: finding a new fundamental theory of physics. To this end, he created a project that calls on scientists or anyone with knowledge of physics to develop the theory. A physics project of all splendor Stephen Wolfram, physicist, computer scientist and entrepreneur, believes that the Universe is a vast network of growing relationships that makes up space and everything it…

Considered one of the hardest materials found on Earth, diamonds serve as a reference for many researches aimed at creating structures that surpass its solidity. Recently, researchers from the University of California at Irvine (UCI) managed to create a nanoscale carbon structure with a much higher strength / density ratio. Leave the cylindrical arrangement in favor of a plate arrangement Featured in the review Nature Communications, this innovative design is based on porous structures composed…

– PhotoStock10 / Shutterstock.com High carbon steel is no longer relevant. Now, the physical properties of steel have evolved thanks to research carried out by an international team led by Hao Chen of Tsinghua University. The researchers used chemical engineering of the limits or CBE to make the steel lighter, more flexible, and yet ultra resistant. Lighter but stronger steel, what for? Steel has many uses, but it is mainly used in the field of…

This is a major advance in the field of IT. American researchers have recently succeeded in developing electronic components capable of functioning at the same voltage level as the human brain. “It is the first time that a component can function at the same level of tension as a human brain” In the context of work on protein nanowires, presented in the review Nature Communications, a team from the University of Massachusetts to Amherst identified…

– Olga Miltsova / Shutterstock.com The increasingly small size of electronic components means that the technology that powers them adopts a similar scale. One of the main challenges for scientists, therefore, is to identify materials that prove to be both ultra-thin and efficient. A major advance in the field of ferroelectricity A team of researchers fromuniversity of berkeley, in California, designed a ferroelectric material ultra-thin that she applied to silicon. The conclusions of their work…

Australian researchers have just made a strange and exciting discovery. According to their work, the electromagnetic force could vary in certain parts of the Universe. Explanations. The Universe would have a partially dipolar structure With gravity, the weak nuclear force and the strong nuclear force, theelectromagnetism is one of the four fundamental interactions ofUniverse. To calculate the intensity of the electromagnetic interaction between electrons and the photons, scientists rely on the fine structure constant, whose…

Japanese researchers have discovered a neural circuit driving physical responses to emotional stress. This is located in the deep areas of the brain, called the dorsal peduncle cortex and dorsal tecta tenor (DP / DTT), which send stress signals to the hypothalamus, a small region of the brain that controls the vital functions of the body. Understanding the neural mechanism underlying physical reactions to stress The stress emotional activates the sympathetic nervous system, which causes…

Physicists have recently developed a working “quantum radar” prototype that uses the phenomenon of quantum entanglement to detect objects. A system that could ultimately surpass conventional radar in certain circumstances. A complex phenomenon Thequantum entanglement describes the strange state in which two particles can become so closely linked that they seem to communicate instantly, no matter how far apart. Measuring the state of one particle instantly changes the state of the other, even if it…

An algorithm dedicated to the study of stars to probe the bowels of the Earth The limit of earth core located some 2,900 kilometers below the surface of the…
