Social Mask, the mask that detects asymptomatic patients | Digital Trends Spanish

It is very difficult to know the percentage of people infected by the coronavirus without showing symptoms, but inventions like Social Mask want to help reduce this problem. This smart mask is equipped with a removable and replaceable module loaded with technology with which it performs multiple functions. In addition to a ventilation system with a filter, a temperature sensor allows real-time monitoring of this parameter, so the user could know at any time if he has a fever. A biosensor integrated in the front of this module is capable of detecting particles expelled by asymptomatic people and, thanks to bluetooth, the user receives a message on his mobile informing him of this. This app for the phone also shows a map with all the users in the environment within a radius of 300 m...

An AI model listens to your cough and detects if you have COVID-19 | Digital Trends Spanish

It is very difficult to distinguish between healthy people and those who are infected with COVID-19, but who do not experience physical symptoms. However, researchers from the Massachusetts Institute of Technology (MIT) assure that it is possible to discover asymptomatic patients through the way they cough. A difference that is not decipherable by human senses, but that can be detected by artificial intelligence, reported the office of press from MIT. In an article recently published in the IEEE Journal of Engineering in Medicine and Biology, researchers unveil an artificial intelligence model that distinguishes asymptomatic people from healthy people through cough recordings. Interested parties voluntarily submit these recordings via web browsers and devices such as cell phones an...

MIT Designs Mask That Inactivates Coronavirus With Heat | Digital Trends Spanish

The use of masks has been proven to be one of the most effective ways to avoid coronavirus infections. Aware of this, a group of researchers from the Massachusetts Institute of Technology (MIT) has designed a mask that inactivates the virus using heat. The researchers hope to develop this mask incorporating a heated copper mesh that runs on a battery and is surrounded by insulating neoprene. Thus, as the person wearing the mask breathes, the air flows through this mesh and the viral particles in the air are slowed down and inactivated due to this device and the high temperatures. MIT. This mask is expected to be of great use to healthcare professionals or the general public, especially when social distance cannot be respected. “This is a completely new mask concept in that it does ...

Astronomers discover a pi Earth, with an orbit of 3.14 days | Digital Trends Spanish

A team of astronomers from the Massachusetts Institute of Technology (MIT) has discovered an exoplanet with a unique characteristic, according to what was published by the news agency Europa Press. It is a planet the size of the Earth that orbits its star every 3.14 days, which is reminiscent of the universal mathematical constant called pi and that measures the relationship between the circumference and the radius of a circle. Because of this, researchers have christened the exoplanet Earth Pi, although it has the less glamorous name K2-315b, due to the K2 mission of NASA's Kepler telescope through which it was detected. MIT News. The relevant finding of this group of scientists has been published in the journal Astronomical journal. Hardly habitable This terrestrial e...

Check the updated table of COVID-19 risks | Digital Trends Spanish

A post in the British Medical Journal gives an account of a table made by Oxford and MIT that establishes the COVID-19 danger scale. This scheme marks different variables such as: the use or not of masks, the physical space of a meeting, if one is speaking or even singing and the degree of optimal physical distance. One of the things that these researchers propose is that the distance of 1 to 2 meters that are considered necessary, should not be taken rigidly, especially considering that they must be combined with all the factors mentioned above. For scientists these rules “they are based on an outdated and dichotomous notion of the size of respiratory droplets. This bypasses the physics of respiratory emissions, where droplets of all sizes are trapped and moved by the...

MIT professor: time is running out for the human race | Digital Trends Spanish

The coronavirus pandemic is just one of the concerns that humanity should have to survive on planet Earth, since the acceleration of climate change is perhaps the biggest problem ignored by the political authorities. So a MIT professor made an urgent call to try to save in part this outcome that is leading the inhabitants of the globe to extinction. According to Henry, Robert N. Noyce Associate Professor of Professional Development in the Department of Mechanical Engineering at MIT, he commented that there are five fundamental challenges in trying to stop the end of humanity. “Our mission here is to save humanity from extinction due to climate change. The mission is clear. And this is a subset of five problems that will get us most of the way there, if we can solve them...

Why razor blades wear out so fast | Digital Trends Spanish

The razors, scalpels, and blades are generally made of stainless steel, feature a sharp edge, and are coated with even harder materials, such as diamond carbon. However, unlike blades, razors wear out quickly after a few uses, despite cutting materials such as facial hair, a material that is 50 times softer than the blade. The same question was asked by MIT engineers, who looked closely at how a razor blade can be damaged by cutting human hair. And the initial observations were striking: They found that shaving hair deforms a blade in a more complex way than simply abrading the edge. In fact, a single strand of hair can cause the edge to chip under certain conditions. Initial cracks Unsplash But it was not the only thing. When an initial crack forms, the blade becomes...
