We are going to explain to you how to mark all emails you have in Gmail as read, something that can help you a lot to speed things up since you do not mind the indicator of unread emails. This is more useful the more emails you have accumulated, since from 50, it is as if there were other pages and it is not so easy to select them all.

This procedure will help you in those cases in which you have more than 50 accumulated unread emails, maybe several hundred or 2000, and you simply want to be able to select them all at once to mark them as read without having to turn pages to do it. It is something much simpler than it seems, and you can do it both in the Received as in any other.

We have not set foot on Mars yet, but the fact that the different rovers that have been sent there have done so allows us to imagine a bit the day-to-day there. Not so much doing a Matt Damon in ‘The Martian’ anymore, but for example to be able to see dust storms, craters, ice or even sunsets on mars.

Of course, when we have been able to see it in the images that NASA gave us they have always shown a blue sunset, with especially cold tones in the case of what we know as the Red Planet. Although it was about subsequent interpretations and treatments, everything has an explanation, so let’s see why we have reddish sunsets on the Blue Planet and they have bluish sunsets on the Red Planet.

Perhaps running away from a tyrannosaurus would not have been as risky as it was painted in ‘Jurassic Park’. Well, it would not have been a pleasant situation with teeth of about 14 centimeters catching him hungry, but the fact is that now a scientific study suggests that the Tyrannosaurus rex they walked slower than we weighed, probably even at our speed.

Taking out of 3D renderings and taking into account your anatomyApparently the king of the Cretaceous carnivores moved on average with a rather low speed. This is something that perhaps changes a little the preconceived image that many of us had of it, assuming that, although without being a velociraptor, the tyranosur reached considerable speeds. Although we will see that this does not mean that when he had to run, perhaps he was running.
