The Masks With Sensors: Detect Covid-19 in Record Time

A team from MIT and Harvard Universities have been working toward it for weeks. They are still in the testing phase, but they assure that the results are very promising and that they could be distributed in late summer.

“Evidence, evidence, and evidence,” I told the director-general of WHO, Adhanom Ghebreyesus in March. All countries should carry out tests to detect coronavirus cases and thus have greater control over the disease.

Masks With Sensors

It may not be an easy task and many countries have not done it for this reason. Current detection systems are slow and expensive, like PCR, or do not always detect the virus, such as serology. They are better than nothing, without a doubt; but to improve them other faster methods are being investigated. Scanners, drones, or the newer ones that use sensors in police helmets or clothing are some of them.

We now know the case of masks that detect Covid-19. Now that its use is increasingly widespread, and that in some countries such as Spain it is mandatory, your news is more interesting and useful than ever. Can you imagine that your mask, the one you carry with you everywhere, tells you if you have been infected?

Well, it is not a fantasy, but it is closer than you think to become a reality. A scientific team from MIT and Harvard universities have been working on it for weeks. It is still in the testing phase but says the results are promising and could be distributed to the public in late summer.

“We’d love it to be sooner, but our team is relatively small,” says Jim Collins, who leads the research, to Business Insider. “We work as hard as we can.”

How can they recognize him?

The key is in sensors that are incorporated. These sensors are designed to recognize the virus when an infected person breathes, coughs, or sneezes. The emitted particles come into contact with the sensors, where they have previously recorded the genetic sequence of the virus.

This detection could last several weeks at room temperature. To achieve this, they engrave the genetic material on the cloth or the mask material using a machine, the lyophilizer, which is also used, for example, in food preservation.

And after detecting the virus?

The masks detect Covid-19 and then turn on. At the moment, yes, the signal they emit is very slight and is barely visible to the naked eye, so in the experiments carried out in the laboratory they use a device that helps in the task, the fluorimeter. We understand that part of the work that lies ahead involves perfecting this aspect.

However, the horizon is positive. In another similar investigation in 2018, also led by Jim Collins at MIT, they managed to detect several viruses and that the laboratory sensors illuminated in different colours, from yellow to purple. Will they achieve the same in masks?

Your main advantages: fast and affordable

It would certainly be very comfortable. Above all, because unlike other detection methods, this one is almost instantaneous in its diagnosis. According to the estimates of the team that develops it, in two or three hours, it can already confirm the presence of the virus; considerably less time than PCR, which can take 24 hours to diagnose, even longer, in addition to having to send samples to a laboratory for analysis.

If we look for faster methods than PCR, there are, yes; but they are less reliable, because they do not evaluate the virus, but its symptoms. Serology allows us to know if a person has developed antibodies against this disease, but these do not arise immediately after being infected but take about a week. In the case of systems that measure body temperature, they detect fever, which usually occurs when sick with coronavirus. But we know that there are people who are infected and who do not have it. Does a system serve to detect most, but not all, cases?

New App Reveals Sugar Counts in Food

At this point in the film, we are all aware that we eat too much sugar. We like it and that is why we consume it, But we also do it without realizing it: the vast majority of processed foods carry a good load.

Why? The explanation is not simple, in fact, there is no single answer. We can point out, first, that it is cheap; If it were expensive, the food industry probably wouldn’t add it with such enthusiasm. But what good is it cheap if it doesn’t convince consumers?

Sugar Counts in Food

The question, of course, is that it does convince, and a lot. It can be said, without exaggeration, that we are addicted to sugar and that we need the products to be very sweet to be more palatable.

He is the creator and director of the sinazucar.org project, which precisely aims to make visible how much sugar the foods we consume to have. It does it in the most graphic way possible: by means of very simple photographs, in which it shows a product next to its weight of sugar, represented in lumps. The result is very direct, very easy to understand with a single glance.

If we say, for example, that a Coca Cola has about 37 grams of sugar per 100, the amount seems high, but is it? The figures do not tell us much; are difficult to understand. On the other hand, if we look at Coca Cola with its equivalence in sugar cubes, the understanding is much clearer.

How Much Sugar Do Everyday Foods and Products Have?

Or what about ice creams, for example, that now in summer are so much in the mood? A Double Chocolate Magnum contains about six cubes of sugar, about 23 grams per 100, while a small tub of Ben & Jerry’s Chocolate fudge brownie, 30 grams, about seven and a half cubes.

However, from sinazucar.org they do not only include clearly sugary products, such as chocolates, soft drinks or cookies. In the vast catalogue that they have analyzed and that they share on social networks, such as Facebook, Instagram or Twitter, and that they are expanding at the initiative or request of third parties, they also report the high content in less suspicious products, such as fried tomato, juices from fruits or yoghurts to drink.

Antonio tells us that a little over three years ago, a nutritionist recommended that he decrease his sugar intake to improve his sports performance. Then, he began to look at the labels of commercial products and realized that even those products that he considered healthy contained a large amount of sugar. Furthermore, few people, very few really, were aware of it.

He did not hesitate and began to share this discovery with the rest of the world, using his experience as a photographer. Very soon, his shocking images went viral and a large number of the media became interested in his project, increasing his notoriety. Such has been his success in these three years that more than 10 million people have seen his photographs and his book, with the same name as his page, sinazucar.org, has become one of the best-selling online of recent times, reaching number one in January 2019.

However, as he himself indicates on Twitter, it is not a question of panicking: sugar is not poison. What happens is that we take it in excess and that itself is harmful to health. There are plenty of illnesses and associated damages: from cavities to being overweight, obesity, and an increased risk of Type II diabetes and some cardiovascular diseases. Of course, a more balanced and conscious consumption will improve your health.

The key? According to her, “the greatest effort to reduce it begins in the supermarket. If you have an insane product at home, sooner or later, you will eat it; if you don’t buy it, you don’t eat it ”.

Why Millennials Don’t Like to Make Phone Calls

The millennials are the generation of text messages and rarely hear about them by phone. Is it because they feel it as a thing of the past? Or is it because of the need to be multitasking?

Many will say that calling by phone is overrated, that a message on WhatsApp or a direct message on Instagram is more than enough to keep in touch. But, coincidentally, all who claim this are the same age, known as Generation Y. That is, those who were born between 1981 and 1993. Why is it the generation that least tends to talk on the phone?

Millennials

It seems that they have many reasons, among which stand out: being highly productive or thinking before speaking. These characteristics, among many others, are common in the youth of this generation, which many classify as the most prepared and, also, as the most frustrated. Below, we discover its main reasons.

Because They Require Immediate Attention

A message can be answered at any time, while if they call you you have to spend time at that moment.

Also, by calling it is much easier to answer something that you can later regret. Either because you answer with little desire, and it shows, or because you are one of those who do not have a filter and lose the first thing that goes through your head.

Do the Words are gone With the Wnd

In a hyperconnected world, we can’t blame millennials for being paranoid when they prefer to have it all in writing. It never hurts, both so that you don’t forget anything, and to use it if necessary.

In the work environment it is a key strategy, since, for both good and bad, it will always be better if there is a written record of everything.

Calls Are For Serious Issues

It is usual to see the following scene: a millennial’s cell phone rings, he is amazed and sees who is calling him. He hesitates and answers with “Has something happened?” This means that phone calls are related to important or urgent issues.

So, if when they respond they realize that it really wasn’t anything interesting, their usual response is a: “And that’s what you’re calling me for?” or “Ah ok, I was scared to see that you were calling me.”

For all this, this generation prefers to spend their time writing via WhatsApp, Telegram or Instagram. So if millennial calls you do not panic, but be very attentive, because it will surely be important.
