A bracelet against sunburn Created in Scotland, the bracelet changes color when ultraviolet exposure exceeds the recommended limits   Researchers at the University of Strathclyde, in Glasgow, have developed a simple and economical system to prevent the risks of excessive exposure to the sun: a water-resistant bracelet. The Smartsun device changes color according to the amount of exposure that the user receives from UV rays. The bracelet is originally yellow, but turns pink as the exposure increases, warning its users to put themselves in the shade. The sensitivity of this material to ultraviolet light makes it possible to warn of danger even before the skin is damaged. How does it work? The Smartsun bracelet monitor works by changing the color, a purely chemical process created by an acid-releasing agent that detects ultraviolet light and a contrast that responds to the pH levels in the indicator. The release agent is broken down by sunlight, which leads to a rapid ...

Science reveals the secrets of art Infrared, x-ray radiographs or exposure to ultraviolet light are essential techniques for historians and restorers to decipher the true story after the works    In a precise intersection between science and the arts, in the Department of Technical Studies of the Prado Museum, researchers apply the methods of the first to the second. They try to extract from the works all the possible empirical information to put it in the hands of conservators and restorers. In recent years, technical reports have helped them to discover, for example, the copy of La Gioconda made in the study of Leonardo da Vinci himself. His analysis included infrared reflectography, X-ray scanning, ultraviolet fluorescence induction, stratigraphic analysis and solubility tests. "Normally I do two infrared of each frame, one before and one after the restoration. In La Gioconda I made five, but of course, they are special paintings that demand another way of actin...

Disney can turn any toy into a speaker The company's R & D department has developed a technology that allows printing objects capable of emitting sounds, whatever they may be.    A group of researchers from the Disney Research Labs, the high-tech division of the multinational, has found a way to print objects that are, in addition, a speaker capable of playing music or complex sounds. This technology, they hope, will allow them to create all kinds of toys with which they can interact through the ear.    The technique developed by these scientists allows them to convert almost any object into an electrostatic speaker. They do not incorporate a sound emitter inside the structure, but it is capable of playing music. In any direction, and from everywhere. Even if the pileup is held in your hands. All thanks to a 3D printer, a paint with high electrical conductivity and electricity. These objects, half toy half speaker, are created in two phases. On the ...

The heat of the spacecraft will be used until the last drop They create a device that allows generating electricity with the residual heat that is generated inside the spacecraft, which until now was wasted    A group of students from Rice University (USA) has developed a device that transforms waste heat from spacecraft into electricity. They believe that the invention, created with the advice of NASA, could work only with the excesses of temperature suffered by the electronics of the International Space Station.    When discovering the waste of energy that happens in the space, the students of this American institution decided to start up a work that facilitated a remedy. The team has used thermoelectric generators that transfer heat from cooling tubes, such as those used to radiate into space, and that can fulfill various functions. Specifically, they can develop their primary task of generating electricity, while the cooling of the station and its ...

The driverless car from Google can now move around the city For about a year, the 24 Lexus RX450h equipped with Google sensors have been circulating the streets of Mountain View   Google is moving forward on its project to create a car that drives itself, and has just revealed that during the last year several prototypes have circulated in urban areas, something that, according to the company, is much more difficult than doing it by motorway.
