That's MeowTalk application capable translating cat Meow thanks to artificial intelligence: If you have pets you have surely thought more than once what your cat or dog was trying to tell you with its meows or barks.

However, that now will not be a problem, at least in the case of cats, thanks to a new application that translates their meows.

This tool developed by an engineer involved in the process of creating Alexa could mean a great leap in terms of human communication with the animal world.

“I think this is especially important now because with all the situation of social distancing there are people who are confined at home with their cats,” Javier Sánchez, the group's technical program manager at app developer Akvelon, has explained in a webinar.

The MeowTalk app, available for free for Android and Apple, Records the sound of the animal and tries to identify its meaning thanks to artificial intelligence in the form of a human voice.

The creation of this system has been tremendously complicated because research suggests that these animals do not share a common language, but that each cat's Meow is different from the rest.

At the moment, it is only able to detect 13 phrases, such as: "feed me" or "I'm angry", although the system is designed so that the cat owner can also tag the sounds and thus expand the individualized database of AI.

With an average rating of 4.3 on the Google Play Store and still under development, the application has had all kinds of reviews, from some positive that find it quite fun and promising, to others that express failures or concerns.

Specifically, users are concerned about the privacy of the application in terms of storage and use of the data of the recordings, since in their privacy policy they point out that at the moment they do not fully comply with the EU GDPR privacy law because it is not finished.

Although at the moment many translations may lack accuracy, the ultimate goal of this project is to develop a smart collar, where a human voice would instantly translate the cat's Meow through the accessory.

However, experts point out that there is a possibility that the sounds that cats emit are an indecipherable unknown.

"We'll probably never be able to turn a cat's Meow into human words," explains cat behaviorist Anita Kelsey. "All we can do is have fun thinking about what they might be saying from our own human perspective."

NASA is developing new spacesuits for the first time in 40 years-these are the rigorous tests you have to go through before you go into space

Narrator: the truth is that this is not your usual swimsuit. It is actually NASA'S 'exploration Extravehicular Mobility Unit', or XEMU, the first flight spacesuit newly created and developed by the agency in more than 40 years. And that's what future astronauts will wear when we finally return to the moon in 2025. But before your boots touch the Lunar surface, the suit should be rigorously tried on.

Amy Ross: we know that if we don't do our job right, we can kill someone.

Narrator: the test is not just to make sure it works. It's about making sure that the astronauts who use it return home safely.

Ross: We are a life support system. And that's something we all know and keep in mind every day as we do our job, because Rule Number One is for crew members to come home.

Narrator: This Is Amy. And Amy has to make sure that the suit will be able with everything. The Artemis program plans to take crews to the South Pole of the moon for months, in gloomy regions that could drop below 370 degrees Fahrenheit or even higher. And astronauts will have to act as geologists, especially after NASA's discovery of ice on the moon, something that could help fuel the Rockets, turning the moon into a gas station on its way to Mars. So the xemu testing process has been long and exhausting, with some testing done twice the recommended amount just to feel safe.

Everything has been divided into three phases. Development, design verification and qualification. The first phase is about finalizing a design. Amy and her team test a bunch of different low-quality components before deciding which design they are going to build.

Ross: it's like a car. Is the direction good? Well, until you put it in a car it's very hard to say. We can put different backs and see, Will this one work better than the other?

Narrator: once all this is resolved, the costume goes to the design verification stage.

Ross: the idea is that we're going to stay on the moon for months. And that means it has to be very flexible and capable, and it has to be durable.

Narrator: we have been on the Moon before, but not for so long, not at that point and not with the knowledge we have now.

Ross: they ask us to go to permanently shaded regions because there are gases in those places that remain very, very cold. And I'm softening from a cold minus 370 degrees Fahrenheit.

Narrator: they won't work in temperatures as cold, but the suit has to withstand temperatures as high as 250 degrees Fahrenheit and as low as -250 degrees Fahrenheit, a wider range than ever before. To ensure endurance, NASA tests the suit in what is basically a large vacuum-sealed oven/freezer, with or without crew.

Ross: camera B, one that's here at Johnson Space Center, will be the one vacuum thermal camera for humans that we're going to use. We will go in there with a portable life support system on the back, and then test the suit in its different phases of operation to make sure that it is maintained and functioning in the vacuum and in the thermal environments we will face.

Narrator: along with the temperature controlled, the suit should be durable. When we first went to the moon, scientists were concerned that the lunar surface covered with regolith would not bear the weight of people and machines. But the real problem with regolith is that it is sharp and very dusty, something that could resent the operation of a special suit. So what is the perfect place to test for dust resistance?

Ross: in a dusty, rocky environment.

Narrator: this is what durability testing is like in the Arizona desert.

Ross: and that tells you which parts of your suit are affected by dust, does it give so many problems with dust? Is your mobility system really capable of walking on this rugged terrain? That kind of stuff.

Narrator: but the desert simulates the terrain of the Moon and not much else. To test mobility in Lunar gravity, engineers have to move to a more humid place.

Ross: just like the Neutral Buoyancy Lab, our big pool.

Narrator: in this giant, 40-foot-deep pool, astronauts can see what it feels like to be on the Moon, to a certain extent.

Ross: it's not like the gravity of the moon, because when you try to walk you have to push yourself through the water. But as a reasonable analogy for doing some activities, okay.

Narrator: activities such as climbing stairs, using tools, and ceremoniously planting the American flag. These tests allow engineers to collect objective data on the life support system and mobility of the suit, but also subjective data on the experience of the crew when using it

Ross: our suit isn't ready until they say it's ready and they like it, and they think they can wear it to do their job.

Narrator: now, qualification tests include many of the same things as the design verification itself, but there are some key differences.

Ross: part of it is the paperwork.

Narrator: things get a little tighter at the qualification stage.

Ross: we're very careful to make sure we understand everything that's done with flight hardware. If you change a screw, there is a piece of paperwork, which says this new screw has been put on this date in this particular place.

Narrator: since this is the stage where low-quality test hardware is swapped for state-of-the-art flight-ready material, testing can go a little slower. But in the end…

Ross: when you do qualification tests, you really use that as a test for everyone to put in front of everyone who says that suit is good for flying in space.

Narrator: and once they have the green light...

Ross: it's when you put it in the vehicle, take it into space and use it on a mission.

Narrator: NASA plans to send the xEMU for use on the International Space Station in 2023 to collect flight data and confirm the overall performance of the suit. It is important to note that this is not really considered a test.

Ross: at NASA, we have to feel that we are very confident that that hardware is going to work the way it was required before we flew it. We don't usually get on the flight calling it a test.

Narrator: instead, it's a flight data Mission. And it will be one of the last major milestones before the xEMU is ready to land on the Moon. Spacesuit testing can take years, thousands of elbows, and even more testing than we can teach here. P
