On Friday, a group of British scientists from the University of Cambridge published an article in Science Advances magazine about the development of promising technology for the production of relatively inexpensive screens of almost unlimited size. Do not be confused by the mention of a Friday and British scientists who have scolded the mouthwash. Everything is honest and serious. The study is based on the study and use of the long-known plasmon quasiparticles within the framework of the physical phenomena of plasmonics. In short, plasmons represent a cloud of electrons on the surface of a material. They possess certain collective properties and, depending on a number of factors, can emit light in the visible range with a given wavelength (color).
Scientists from Cambridge have developed a technology for mass production of plasmon-based screens. The smallest particles of gold were covered with conductive plastic polyaniline and evenly sprayed on the plastic surface with a mirror coating previously applied on it. Each granule of gold on the surface is the basis for a miniature pixel, the dimensions of which are a million times smaller than that of the screens of modern smartphones. The technology is very simple for mass production, as the developers insist. Such screens with billions of pixels per meter can be released with continuous tape at high speed. We are talking about the production of flexible displays literally the size of the wall of a multistory building.
Light falling on such a screen falls into a trap between plastic-coated gold nanoparticles. Conductive plastic coating under the influence of the control voltage in a given way changes the chemical properties and causes a change in the wavelength of the reflected light in a wide spectrum (the wavelength can be reduced to 100 nm or less). The pixel begins to glow in a given color and, importantly, such a bistable state that it does not require power to hold the selected color.

Prospects for such screens are huge - from information to camouflage. The highest resolution will allow to hide the fighter even in open areas, and the use of the architecture will open the way to new and unusual solutions. Displays for electronics will also receive an impetus to development. They will be well read in bright sunlight and will cease to be the most active battery charge eaters. But before that there is still a long way to go, improving and developing technology. In particular, the team of scientists began to work on expanding the color range of displays based on the technology presented. Read more about the development in the article in Science Advances.

Japan began testing its Alfa-X bullet train for the Shinkansen lines, which can reach speeds of up to 400 km / h.
This is reported by the American broadcaster CNN.
The first tests of the composition of 10 cars began on Friday, May 10th. The tests will be carried out twice a week, after midnight, between the cities of Sendai and Aomori.
It is expected that the train will be commissioned by 2030 - then it will travel at a speed of up to 360 km / h, which will make it the fastest passenger express in the world.

Before the competition of robots, comedians still far.
An ambitious task recently set by American programmers. The goal is to make a firm out of the "corporal." Chinese scientist and developer of heuristic computer systems Hee Hee from Stanford University plans to instill a sense of humor in artificial intelligence, writes Wired.
According to the developers, the most difficult thing is to teach artificial intelligence to improvisation and sarcasm. Since the intellect works according to a certain algorithm, and this excludes creative initiative and resourcefulness.
Hee Hee is sure that artificial intelligence cannot be made ridiculous, even if you load all the jokes and anecdotes of the world into a neural network.
During training, Hee Hee and his team decided to test the theory of wordplay and let the neural networks memorize several homonyms so that the intellect could generate funny sentences by replacing concepts with them. So that after replacing the joke does not lose its meaning, the neural network adds a couple of new words to the sentence. And although the results are not yet encouraging, computer heuristics experts intend to continue research.

Microsoft may release a controller for its Xbox gaming consoles, in Braille. At least, the manufacturer filed a patent application as early as October 2018.

The accessory will provide an opportunity to play with visually impaired users as comfortably as possible, however strange it may sound. The design resembles a controller for the Xbox One, on the reverse side there is a mount for a Braille display with six petals protruding on the sides. The braille display can display text or audio through braille. This can be used to read instructions, menus or chats. Plus, the controller will be able to recognize the user's voice commands and convert them to Braille.
Whether this development will see the light, time will tell.

Novelty called Xiaomi Ninestars Smart Trash Can. You can purchase this device for $ 19, Belnovosti reports.
It is known that the trash bin received an intelligent mechanism. Thanks to him, it can silently open and close. However, this is not all the features of the device. The developers have equipped the novelty with a sealing mechanism that prevents the spread of odor. Also, the infrared recognition system opens the bucket automatically, you only need to bring your hand up to 30 cm. The bucket capacity is 10 liters. The wonder device works on batteries.
Overall, the performance is pretty good. Representatives of the company are confident that the new product will make it easier for the kitchen and will not disturb the interior of the room.
