Perseverance lets us know what it sounds like to roll on Mars for the first time in history


Ever since Perseverance landed and got underway, we’ve been keeping a close eye on what NASA’s rover can tell us. We have already seen the first high-resolution photos and now what it shows us is what it sounds like to move around Mars.

A curiosity that, although it does not represent any kind of scientific milestone, is still the first time that we can hear a vehicle moving around the Red Planet. And it’s certainly not the quad-like or, shall we say, terrestrial sound we would expect, starting with the metal wheels and ending with the rocky terrain the rover has been traversing.

In addition to carrying the same processor as the 1998 iMac, Perseverance also integrates a high-sensitivity microphone with which it has captured its time on Mars. NASA is now making public the approximately 16 minutes of the rover’s driving on the Martian surface.

It’s a 27.3-metre walk through the Jezero crater on 7 March. The truth is that it is nothing like what our car does on rocky terrain.

It is an almost eerie sound, not very pleasant, but according to the agency it is normal. What we hear is the interaction of the rover’s mobility system (the wheels and suspension) against the surface alternating with this tearing sound (less pleasant and high-pitched), the origin of which is still being studied. It seems that this could be due to electromagnetic interference from one of Perseverance’s electronic circuits, or from the same interactions with the surface as the other sounds.

These sounds are in addition to those already captured by Perseverance from the Martian winds, with another microphone that is part of the SuperCam, which is used to study the structure and composition of rocks (partly looking for traces of life). In addition to all this, the rover has been looking for a landing site for the accompanying helicopter and according to NASA it is already located, so flight tests will soon begin.

With all this we know the rover a little better and we can say that we are hearing something about 56 million kilometres away. It is not Vivaldi’s Spring, but these are curiosities that have their technological value.

Brazil registers new record with more than 90,000 cases of COVID-19 in one day


Brazil recorded 90,303 Covid-19 infections on Wednesday, a new daily record, bringing the country’s total to 11,693,3838 cases and confirming it as the current global epicentre of the pandemic.

The death toll was also high in the last 24 hours, with 2,648 deaths from the virus, the second highest after the record 2,841 deaths recorded on Tuesday, bringing Brazil’s death toll to 285,000, according to a bulletin released by the health ministry on Wednesday.

The more than 90,000 confirmed infections on Wednesday surpassed the 87,840 reported on 7 January and the 85,660 cases of covid-19 reported on 12 March, the highest ever for a single day.

The average number of deaths in the last week reached 2,017 deaths per day on Wednesday and the number of infections reached 70,219 cases in a single day, figures never before seen in the South American giant since the beginning of the pandemic.

According to the ministry’s balance sheet, the covid-19 case fatality rate remained at 2.4 per cent of the population, the mortality rate rose to 135.5 deaths per 100,000 inhabitants and the incidence rate stood at 5,564.6 infected in the same proportion of the population.

The high averages in recent days confirm Brazil as the nation with the second highest number of deaths and infections from covid-19 in the world, only surpassed by the United States.

The increase in fatalities was expected in Brazil, where the lack of beds in intensive care units (ICU) has caused the country to experience the greatest health and hospital collapse in its history, according to official data.

In 25 of the country’s 27 states, ICU occupancy rates are equal to or higher than 80%, and in 19 capital cities, which are the most populated, these specialised units have exceeded 90% of their capacity.

This situation has accelerated deaths from covid-19, especially in the states of the southern region, where so far in March a record number of deaths have been recorded (Paraná with 2,245 victims, Santa Catarina with 1,600 deaths and Rio Grande do Sul with 3,214 deaths).

The situation is alarming in Porto Alegre, the capital of Rio Grande do Sul, which has the largest number of inhabitants in the region, as the demand for ICUs in hospitals today exceeded capacity by 114%.

What are leads in marketing and how to generate them?


If you are very interested in digital marketing, and taking into account that it is becoming more and more trendy and more people are turning their businesses in that direction, you should know what leads are and why they are so important nowadays.

Phrases like “generate leads” or “convert leads into customers” are often heard (and read), but what is a lead? What are they for? How to work with them? We would like to talk to you about all of this and much more below.

What is a lead?

This strange term, which can get many people’s heads spinning, has a very easy to understand meaning. If we analyse what it refers to, we realise that a lead is actually a person. A user. But not just any user.

Imagine that you enter a website because you are looking for a product. That is, you still don’t know if you are going to buy it or not, if you are interested or not. Well, all this turns you into a lead, or in other words, a potential customer. The mere fact of entering the online shop means that you are already in the initial phase of a purchase cycle.

A lead can be defined as a user who is considered a potential customer or a person who could complete the whole purchasing process of a specific product

Therefore, a lead can be defined as a user who is considered a potential customer or a person who could complete the whole purchasing process of a specific product (or service).

That is why the phrases that we mentioned before that you hear (and read) have a lot to do with potential customers, or just customers, not only for online shops, but for any website on the Internet. For example, a newspaper will be looking for a lot of readers; a blog the same, a gaming website will be looking for a lot of gamers playing games…

Why leads are important?

Although this is more than answered in everything we have said before, the truth is that, nowadays, it is more and more important to get leads. Bear in mind that we are increasingly saturated with information, shops… The ease of creating websites, as well as the rise of e-commerce has meant that more and more entrepreneurs are turning to Internet networks to invest in their businesses. And that means reaching potential users, or leads.

According to the experts, the Internet is going to change our shopping habits, and it is already doing so. More and more people are buying online because they prefer to save money and have it delivered to their homes (even if it is more expensive, the fact that it is delivered to their homes is a plus). This is why leads, or potential customers, will determine the success or failure of a website. Because, if you don’t have an audience, how are you going to go ahead offering something that nobody is interested in?

Types of leads

Some marketing experts determine that there are three types of leads to consider. They can move from one level to another, but almost all leads that come to a website can be categorised into them. They are.

Cold leads

These are those users who arrive but do not have a stimulus to buy. In other words, they are simply curious to see what they see. It’s like when you go to a shop to “look”. If you end up buying something, it is because you go from being a cold lead to a warm lead and from there to a warm lead. But if you leave with nothing, or just information, then you will still be cold.

Warm leads

These are users who are somewhere between cold and warm. They know what they need or want, but they have not yet taken the final step to purchase and are still evaluating whether it is really what they want or if something else is better.

Warm leads

These are those users who are ready to buy, who have researched and know what they want to buy, so they will do it or, if they can’t do it by themselves, they will look for you to help them complete the purchase process.

How to generate leads?

Can you generate leads and is it possible to create them? Yes. And no…

In order to generate leads it is necessary, first of all, to know who you are targeting. In other words, we are talking about knowing who the product or service you are offering is for. Because, in that way, you will be able to establish a marketing strategy to reach those people and, then, yes, generate leads.

And how do you do that? We give you the keys:

All of this will help you reach potential users who, if they enter your website, will start the process of converting them into leads. Of course, not everyone who enters will convert from potential customers to customers, so keep this in mind.

Engaging content

And how do you get them to convert? By making them fall in love with what you offer. Both the design and the texts must be focused to generate a reaction, if possible positive, in them. That’s why you should take good care of what you give them so that they follow the conversion process.

A personalised treatment

This is becoming increasingly important. The fact that Internet businesses are booming means that there is more competition. But if you manage to give them something that others don’t offer, they will prefer you over others.

Actress in ‘Avatar’ and ‘Avengers: Endgame’ explains what it means to be in the two highest-grossing films in history


Zoe Saldana seems to be a guarantee of huge success in Hollywood. She has a starring role in Avatar as Neytiri and plays Gamora in the Marvel Cinematic Universe. She appeared in Guardians of the Galaxy 1 and 2, Avengers: Infinity War and Avengers: Endgame.

Thanks to her participation in three of the five highest-grossing films in history, she is the second highest-grossing actress in history. Combined, the films in which she has starred have grossed more than $11 billion.

Zoe Saldana has a starring role in Avatar and plays in Avengers: Endgame

But it was Avatar that changed everything for the actress. Her starring role and the fact that the film became, for ten years, the highest grossing film in history has been decisive.

In 2019 Avengers: Endgame finally overtook Avatar at the box office, but thanks to a re-release in China, the latter returned to the throne, although it may only be temporarily, provided Marvel decides to do the same.

Zoe Saldana is also the only actress to have starred in two films that have broken the $2 billion box office record. The actress knows how important this is and has posted on social media about it.

Saldana will continue to be active in both franchises. She will reprise her role as Neytiri in all Avatar sequels and will appear as Gamora in Guardians of the Galaxy 3. We assume she will be in more Marvel Cinematic Universe films, as the character became important in the events of Avengers: Endgame.

Avatar 2 will be released on December 16, 2022, but it will be one of four sequels the film will have, which James Cameron is working on and Zaldana aims to be in all of them. She has certainly made the right choice of film projects to be involved in.

St. Patrick’s Day 2021: Why is it celebrated on 17 March and what does the colour green have to do with it?


St. Patrick’s Day is here. Every year the arrival of March 17th is awaited to celebrate one of the most international holidays of all those celebrated around the world. Saint Patrick’s Day originated as a holiday in honour of Patrick in Ireland and was initially only celebrated in that country. But over time, it has spread to every corner of the globe.

The origins of St. Patrick’s Day

We all know that St. Patrick’s Day is celebrated on 17 March, but do we know why? Because this is the date on which the patron saint of Ireland died. Curiously enough, he was not Irish but came from England. Legend has it that his original name was Maewyn and that he was sold into slavery as a teenager when he arrived in Ireland. He later escaped and was ordained a priest, adapting the name Patrick.

St Patrick Day
Happy St. Patrick’s Day 2021! The 17th of March has become a day of celebration around the world to celebrate the patron saint of Ireland. We discover the origins of this celebration and why you can’t miss the beer on St. Patrick’s Day.

When he returned to Ireland, he devoted himself to converting pagans to Christianity. Tradition has it that he was responsible for driving the snakes off the island and for making the three-leaf clover the symbol of the country. He died in 461 in Saul, County Down. St. Patrick has been the patron saint of Ireland since 1780.

St. Patrick and his traditions

Many Irish people had to leave their country of origin and emigrate to different places. It was thanks to them that the celebration of St. Patrick’s Day began to gain momentum in different countries. In fact, the first St. Patrick’s Day parade was held not in Ireland itself but in Boston in 1737. Nowadays, New York held (in pre-covid times) the largest parade of all, with an average attendance of some two million people, and others such as Chicago even dyed its river green in honour of the saint. In addition, various monuments around the world turn green in honour of the saint.

Because the colour green is another of the traditions linked to Saint Patrick. And it seems that originally it was blue, but in the 19th century it changed to green. Shamrocks come to life on this day and people often wear green clothes and even brew green beer.

St. Patrick’s Day is also a time when tradition invites people to get together with friends and drink a few pints of beer. In fact, it is the day of the year when most Guinness beer is consumed. It is estimated that the number of pints of beer served on a normal day doubles and up to 13 million pints can be consumed. And you, how are you going to celebrate this St. Patrick’s Day?

Apple to discontinue original HomePod to focus on next-generation HomePod mini


The original HomePod, launched at the end of 2018, will not have a new model. After several months of speculation about the release of a new version, Apple has confirmed that they will stop manufacturing it. They will focus on the evolution and next generations of the HomePod mini, which takes the baton as an evolution of the technology with which the company inaugurated its family of smart speakers.

Apple will continue to provide support and software updates for the original HomePod, which will be sold while supplies last to focus on HomePod mini technology.

For all customers who already have their HomePods at home, Apple will continue to provide support and software updates, and they will continue to be available while supplies last.

HomePod HomePod MIni
Apple has confirmed that they will stop manufacturing the original HomePod

The original HomePod was Cupertino’s first major entry into the smart speaker segment. It was the first inclusion of its own technology for great sound and a spectacular Siri listening system that was the result of years of research and development. With HomePod mini, they wanted to evolve the concept.

HomePod mini and its goal of taking HomePod technology further

Apple’s announcement means that the range of smart speakers will continue to improve: the arrival of the HomePod mini was a departure from what we knew with the original model, in a smaller, cheaper format and with features that are anything but “mini”. The company’s research will continue with them to improve the audio experience on these devices.

Here the experience Apple has taken in recent years is essential: the AirPods inaugurated the path towards miniaturisation while maintaining quality sound, which has been refined with the AirPods Pro and more currently, with the AirPods Max: no doubt the roadmap goes through offering a more powerful sound in a more compact space, which will be part of this next step in the life of computational sound and the research they have started with the tremendous success of the HomePod mini.
The experience in miniaturising components and the advances in research and development over the last few years, to achieve better sound experiences, will be the key to the next generations of HomePod mini.

We can almost consider this success of the “mini” models as part of Apple’s history: it happened with the iPod mini, which managed to become the best-selling model of the family, or with the Mac mini, which the company has evolved over the years to become one of the flagships of the new generation, including the Apple Silicon M1 chips. And while not strictly the same surname, the MacBook Air was also born from that concept and ended up laying the foundations in portability and key points for the visual language of today’s MacBooks.

Global arms trade stagnates


The global arms trade has remained at the same level over the past five years after years of increases, due to falling exports from Russia and China, according to a report released today by the Stockholm International Peace Research Institute (SIPRI). Total volume fell by 0.5 per cent between 2011-2015 and 2016-2020 for the first time in nearly two decades, despite “remarkable” increases by three of the biggest sellers, led by the United States, which increased its share from 32 per cent to 37 per cent. “It is too early to say whether the period of rapid growth of the last two decades is over. The economic impact of covid-19 may cause some countries to firm up their arms imports in the coming years,” says the report, which hints at the signing of large contracts during 2020.

The United States, which sold arms to 96 states (almost half of them to the Middle East), increased its sales by 15 % and widened the gap with Russia, which suffered a 22 % drop due to a decline in its operations with India, although it maintains its status as the second largest seller with 20 % of the total. The study notes that despite the recent signing of new contracts with several countries, which augurs well for an upcoming rise in exports, Russia faces “strong competition” from the United States in all regions. It is followed by France and Germany, up 44 % and 21 % respectively, ahead of China, with 5.2 % overall and a decline of almost 8 %. The five largest sellers accounted for three quarters of total world arms exports.

Saudi Arabia, the largest importer

With an increase of 61% compared to 2011-2015 and a global share of 11%, Saudi Arabia has established itself as the leader in global arms imports. India, Egypt, Australia and China complete the list of the top five global arms buyers, accounting for 36% of the total. India’s imports fell by 33% over the past five years, partly due to its attempt to reduce its dependence on Russia.

By region, Asia-Oceania was the largest recipient of arms over the past five years, accounting for 42 per cent of the total, followed by the Middle East (33 per cent), Europe (12 per cent), Africa (7.3 per cent) and the Americas (5.4 per cent). “For many countries in Asia and Oceania, a growing perception of China as a threat is the main driver of their arms imports. More large imports are planned and several states in the region are looking to produce their own weapons,” the report writes.

Facebook to multiply ads in videos and stories


If you find advertising on Facebook too much, now you’ll have a reason to get even angrier. Mark Zuckerberg’s company announced new tools for content creators to make more money, which means more ads on videos and stories within the platform.

Until now, advertising on videos was limited to those lasting three minutes or longer. The new adjustment means that ads can now be inserted into videos as short as one minute. According to Facebook, this will be “advertising with minimal interruptions” that can be activated after 30 seconds.

As for Stories, in the coming weeks some content creators will be able to monetise their Facebook Stories through sticker ads. The option will be limited to a small group of people with a view to expanding to more users. Later, sticker ads will be rolled out to short-form videos.

According to Facebook, content creators are generating “millions of dollars” in revenue. The growth in 2020 compared to the previous year is 55%, meaning the tech also pocketed an indiscriminate amount of money from advertising.
Facebook to allow more people to insert ads into its videos

Facebook’s plans are to open up monetisation to more people. The eligibility criteria for adding in-stream ads has changed and now requires a minimum of 5 videos or livestreams posted and 600,000 total minutes viewed in any combination. In addition, videos must be posted from a page with at least 10,000 followers.

Finally, Facebook announced that paid events will expand to 20 countries in Latin America, Europe and Asia. This initiative was announced in August 2020 as a recovery mechanism for small businesses hit by the pandemic. The events have generated thousands of dollars for both content creators and Facebook, so they will expand to more regions.

Facebook will continue to sail under the banner of a company that supports the community in difficult times, a far cry from reality. Behind every implementation – ads, stickers, subscriptions – there is millions of dollars in revenue for the company thanks to the high percentage of operations that are integrated into its products.

In 2020 alone, Facebook made $84.2 billion from advertising.

The keys to Joe Biden’s fight against the pandemic


President Joe Biden, one year into the year since the Covid-19 pandemic swept across the country, delivered his first prime-time address: a speech that mixed hard numbers on vaccine distribution with calls for unity and a deep-seated belief in America’s power to overcome any challenge. Here are the keys to his fight against the pandemic:

1- 4 July, Independence Day…from the virus

Biden on Thursday ordered states to begin vaccinating all adults against EVD-19 by 1 May, so that by Independence Day, 4 July, “there’s a good chance” that families can be reunited. “After this long, hard year, this will make Independence Day something really special where we not only mark our independence as a nation, but we begin to mark our independence from this virus,” the president said of his intention to reach the 4th of July in a better position thanks to vaccination, although he pointed out that “the fight is far from over”.

2- 100 million doses of vaccine

Biden announced that his administration is on track to meet its commitment to deliver 100 million doses of the COVID-19 vaccine in the first 60 days of his term, when the goal was to do so in 100 days, as he assumed when he took office. “We are on track to reach the target of 100 million shots on my 60th day in office. No other country has done this,” he said.

3- Reversing the damage caused by Trump

The US president recalled that the country experienced “denials for days, weeks and then months”. “That caused more deaths, more contagions, more stress and more loneliness”, he lamented, while pointing out that it has been a period of suffering and “collective” sacrifice. The leader also pointed out that the total number of deaths caused by the pandemic in the country, more than 527,000 people, is already more than “in the First World War, the Second World War, the Vietnam War and 9/11 combined”.

4- Call for national unity

Biden used his speech to condemn those who have used the pandemic for hatred “instead of working together”. In particular, he referred to hate crimes against Asian-Americans who, in his words, “have been targeted, harassed, blamed and scapegoated”, to which he demanded that the hatred “must stop”. “We’ve lost faith in whether our government and our democracy can deliver on really difficult things for the American people,” he also acknowledged. In this sense, he called for “national unity”. “After all we’ve been through, we will come together as a people (…). We will come out stronger, with a renewed faith in ourselves”.

5- Let everyone do their part

In his speech, Biden also called on the American people to help him achieve his goals: “I need all Americans to do their part. Biden urged Americans to get vaccinated when it is their turn.

6- More places to get the vaccine

According to the White House, the number of places where Americans can receive the immuniser will be increased to reach hard-to-reach and hard-hit populations. The number of people involved in the vaccination process will also be increased, with a total of 6,000 troops deployed and an increase in the number of professionals trained to administer the injection.

7- Reopening of schools

Further steps will also be taken to reopen schools, with the issuance of Rescue Plan funds for the adaptation of schools to coronavirus containment measures. In addition, it will expand screening in schools, support school staff in vaccination and offer advice to educational establishments, among others.

8- Combating new strains

The United States will also continue efforts to combat new variants and spread in any space by further testing and strengthening the identification of new variants.

Why is illegal abortion so dangerous?


According to the latest research of the World Health Organization, about 45% of all abortions are unsafe. Along with this worrying fact comes the information that up to 13% of maternal deaths every year result from this procedure.

Now, you probably think that this isn’t happening in your country, but somewhere far away. Well, you’re mistaken. In fact, there is a large percentage of illegal and unsafe abortions within developed countries. First of all, let us clarify what do we really mean by illegal abortion.

What Is An Illegal Abortion?

Most illegal abortions are performed under unsafe and unhygienic circumstances. A procedure like this needs to be completed in professional abortion clinic. Not to mention that your doctor needs to own special medical equipment like the table, ultrasound, and other medical instruments. The procedure itself must be done under completely sterile conditions.

There is a large percentage of illegal and unsafe abortions within developed countries

Why Do Women Choose This Option?

Unfortunately, illegal or unsafe abortion can be the only acceptable solution for young women. It’s probably hard to understand that we do not all have the same opportunities even today, and we are not entirely equal, mostly if we talk about money. Without money, it’s impossible to do this procedure at the clinic, so women need to find another way. Also, have in mind that somewhere else, abortion can be illegal, for example, in Africa. In most of the US, this is not the case.

There is the social influence that makes women insecure or even ashamed because of unwanted pregnancy. To solve this problem without going to the doctor and talking about it openly, women usually decide to deal with it alone. They find a place for illegal and unsafe surgical abortion or buy medications. Those medications from the black market are suspicious, less effective, and they can be dangerous. Going to the doctor is always the best option.

Complications of Unsafe Abortion

There are many severe consequences after these procedures, like serious infections or injuries. One of the most common results of unsafe abortion is multiple infections. Unsterilized conditions and medical instruments can cause serious illnesses, which can even cause death if left untreated. Following unsafe abortion, women usually experience injuries to the genital tract and other organs. Unfortunately, such injuries can affect fertility and reproductive health in the future. Also, if the procedure is performed by someone who is not an expert, there is a possibility of having an incomplete abortion. This means that there is still a piece of pregnancy tissue inside your uterus, and it’s followed by heavy bleeding.

Prevention And Control

Illegal and unsafe abortion can be prevented through sexual education in school, especially for teenagers. It’s necessary to mention all the contraceptive methods, including emergency contraception. If we apply this principle, the number of unintended pregnancies and abortions could be much lower. But, the most important thing is that going to the doctor is always the best solution.
