The invisibility cloak is actually 4 and other new technologies – Bergamo Post

 

Researchers around the world are constantly working to create inventions that improve our quality of life. We have compiled the most interesting news announced in recent days. Some are truly amazing.

1) Giraffe, artificial intelligence in three days
has learned to beat anyone chess

The development of computers has been an ongoing process since the invention of the first computer. In the nineties, for the first time, a system called Deep Blue and programmed by IBM defeated chess champion Garry Kasparov, world famous, decreeing a further leap in technology, now able to think more quickly than a human brain.

The last system put to the test in this respect is dated 2015, is called Giraffe, and is a system of machine learning, neural networks consisting of, or mathematical models composed of artificial neurons, that somehow simulates the ‘activities to those of humans. Imitating the functioning of our brain, this machine is able, in 72 hours to learn to play chess at a higher level than the greatest masters. Giraffe played against itself, using a huge database of real games in which he was able to study the operation of the game and moves more suitable in any situation, creating a potential of 175 million different variables.

its creator is called Matthew Lai, a computer scientist who presented this project as a thesis for his master’s degree at University College London. Its hope is to be able to exploit the experiment of Giraffe to be able to teach the computer to complete certain tasks alone, without necessarily possible to program each variable, but letting the machine itself to construct a kind of experience. The possibilities are many, from the control of drones to cars that drive themselves, not to mention the medical field.



2) The invisibility cloak really exists

Cloak -1991

The power of invisibility has always sparked the imagination of writers and directors, so that you do not count the characters in books and films exploit similar powers, donated mostly by clothing or magic items (the most famous of recent years: Harry Potter). In the past there have been many experiments, especially in the military, where it can become totally invisible to enemies could definitely become a weapon more powerful than the bombs themselves, but the results were always partial and unsatisfactory.

Today, for the first time, a team Research managed to really get rid of a fully three-dimensional object, surpassing any magic trick or science fiction book. The object has been coated with a thin mantle, a thick skin only 80 nanometers, composed of a material that is capable of reflecting light. The creators are part of a research team consisting of scientists from California and Saudis, led by Zhang Xhian. The invention has attracted the attention of the prestigious journal Science , that amazement celebrated this extraordinary success.

The developers explained that the mantle is composed of nanoantennas d ‘ gold, positioned one beside the other, which, when activated, are able to channel the light in a special way, making the object covering totally invisible. The size of the coat is minimal, so far has been able to hide only two cells, but it had never happened that a project of this type riscuotesse a success so clear. Xhian Zhang and his team are confident in the potential of this patent also of larger objects and promise amazing results in the coming years.



3) Here comes the rubber repairs itself, a
revolution for tires

Some car manufacturers offering some years already tires capable of resisting puncture milder, with an emergency system that supports the wheel in the event of minor damage, at least until you are not able to reach a tire. Researchers in Germany and Finland, however, were not satisfied, creating a type of rubber that can repair itself completely, even after sustaining considerable damage as cuts or punctures.

The secret lies in the composition of the rubber itself, which it has not yet been fully revealed. The tests are very encouraging and show that the structure of the rubber is really able to restore any damage, even re-establishing the same conditions of elasticity and resistance originally present. The giants of the tires are already on alert, although for now the market is still far away and it will take more years of work to see a product ready for market. Meanwhile, however, we can only dream of a future where punctures and tire changes will be only a distant memory, with consequent savings in economic, environmental and practical.



4) Razor laser has blades and does not irritate the skin

Shaving in the morning is still a ritual for many men, at least for those who still was not convinced by the growing fashion the long beard. Even when the sun is rising and our brain is still struggling to reactivate all the basic functions, however, it can happen that the hand gets out or that we are forced to take more steps than expected on the skin, causing cuts and irritation. Arrive at the office with his face shredded or red neck but can be embarrassing and that’s why you created the razor laser without blades.

The project started on the famous deck of crowdfunding Kickstarter and has currently reached a financing of more than 650 thousand dollars, compared with a target set at only $ 160 thousand. Its creator, Morgan Gustavsson, promises that by 2016 it will be possible to shave with this device, which do not have metal blades will be able to shave beard and hair exactly like a regular razor. The radius laser is output in the same area where it usually is placed the blade and activate the contact with the hair, cutting cleanly without touching the skin and thus avoiding any kind of irritation.



5) Farewell to pesticides comes electrolyzed water


The fruits and vegetables that end up on our tables are always look nice and not They have any kind of imperfection, thanks to treatments using pesticides that farmers play in the growing crop. It is no secret that the chemicals, while keeping out insects and pests, are certainly not a panacea for our body, so that a good part of the Italian ventured into the growing organic market.

Researchers in Tasmania, however, they have successfully experimented with an alternative treatment, based on electrolyzed water, able to act as a disinfectant instead of the chemical agents. The current is passed from one machine through the salt water, creating sodium hypochlorite, ingredient also present in the bleach, which becomes a real natural herbicide. In the past electrolyzed water it has also been used in hospitals to kill germs, but for the first time this technique has been successfully tested also in agriculture. Over the past two years, researchers have used in fields affected by the fungus of onions, which usually destroys about 90 percent of the grass, instead successfully managing to keep more than 90 percent of the field.
