Scientists say they have found the cleanest air on earth

Aerosol filter samplers probe the air over the Southern Ocean on the Australian Marine National Facility's R/V Investigator ship.
In the first study of its kind on the composition of bioaerosols in the Southern Ocean, researchers from Colorado State University identified regions of the atmosphere that remained unchanged by human activity.
Weather and climate are closely interrelated, connecting every part of the world with other regions. As climate change quickly due to human activity, scientists and researchers struggle to find corners of the earth that are not affected by humans.

However, Professor Sonia Kreidenweis and her team suspected that the air above the Southern Ocean was least affected by humans and dust from the continents of the world.

The researchers found that the boundary layer of air, which feeds the lower clouds above the Southern Ocean, is free of aerosol particles produced by human activity. – including burning fossil fuels, growing certain crops, producing fertilizer, and disposal of wastewater – or transported from other countries around the world.

Air pollution caused by aerosols, which are particles and solid and liquid gases that are suspended in the air.

The researchers decided to study what is in the air, and where it came from, using bacteria in the air as a diagnostic tool to deduce the properties of the lower atmosphere.

Research scientist and research co-author Thomas Hill explains that “the aerosols that control the properties of SO (Southern Ocean) clouds are strongly linked to ocean biological processes, and Antarctica appears to be isolated from the spread of microorganisms to the south and the deposition of nutrients from the southern continent,” he said in a statement.

“Overall, this shows that SO is one of the few places on Earth that has been slightly affected by anthropogenic activities,” he added.

The scientists tasted air at sea level – part of the atmosphere that has direct contact with the sea – while boarding a research ship traveling south to the Antarctic ice bank from Tasmania, Australia. The scientists then examined the composition of microbes in the air, which were found in the atmosphere and were often scattered thousands of kilometers by wind.

Using DNA sequencing, source tracking, and wind back trajectory scientist and first author Jun Uetake found that the origin of microbes came from the sea.

From the composition of microbial bacteria, the researchers concluded that aerosols from distant soil masses and human activities, such as pollution or soil emissions caused by land use changes, do not move south and into the air.

Scientists say that the results show a marked difference with all other research from the oceans in both the northern and subtropical hemisphere, which found that most microbes originated in the windward continent.

In the study, published Monday at Proceedings of the National Academy of Sciences journals, scientists describe the area as “truly pure.”

Air pollution has become a global public health crisis, and kills seven million people each year, according to the World Health Organization (WHO).

Research has shown that air pollution increases risk heart disease, stroke and lung cancer.

More than 80% of people living in urban areas who monitor air pollution are exposed to air quality levels that exceed WHO guidelines, the health organization said, and low and middle income countries suffer the highest exposure.

However, as research shows, air pollution can cross geographical boundaries, and affecting people hundreds of miles away from the place of origin.

The Last Lobo, an eight-episode co-production between SPi and Caracol Studios and written by Bruno Gascon, is “a crime drama that tells the story of Lobo, one of Europe’s biggest drug dealers.”

“Code 632”, a co-production of RTP and Globoplay, is a six-episode series based on the book “O Code 632” by José Rodrigues dos Santos.

Recording for this series will begin in July and will be split between Lisbon and Rio de Janeiro. According to RTP, in a statement released this week, the book adaptation for the series is being handled by Pedro López and directed by Sergio Graciano.

“Based on authentic historical documents, Codex 632 focuses on a cryptic message found among the papers the old historian left behind in Rio de Janeiro before he died,” recalls RTP.

The cast included Portuguese and Brazilian actors and starred Paulo Pires and Deborah Secco.

SPi, part of the SP Televisão group, produced the Netflix series Gloria and co-produced Auga Seca for HBO Portugal, among others.

Portuguese rider Miguel Oliveira in 16th place after the first free practice in Assen – DNOTICIAS.PT

Portuguese rider Miguel Oliveira (KTM) finished the first two free practices of the MotoGP Grand Prix in Assen in 16th place.

Oliveira finished the day with a time of 1.34.676 minutes, 1.402 seconds behind the best rider of the day, Italy’s Francesco Banagia (Ducati). Spaniard Aleix Espargaro (April) was second with 0.178 seconds and French champion Fabio Quartararo (Yamaha) was third with 0.305 seconds.

After the first session in the rain, in which the rider from Almada was sixth fastest, the rain stopped before the start of the second session.

The riders started with intermediate tires, but as the track in Assen in the Netherlands, considered the “cathedral” of motorsport, dried up, they installed dry tires (slicks).

Under these conditions, Miguel Oliveira was losing ground in the table, ending the day in 16th place, despite an improvement of about nine seconds from the morning’s record, in rain, in which Australian Jack Miller (Ducati) was the fastest. , fifth in the afternoon.

On Saturday there will be two more free practices and qualifications.

The 10 fastest in the set of the first three sessions go directly to the second stage of qualification (Q2), and the remaining 14 “brawl” in Q1, resulting in the two fastest qualifying to the next stage.

Portuguese MNEs defend that Mercosur is a "natural partner" of the European Union at the moment - Observer

This Thursday, Portugal’s foreign minister said that at a time when the European Union (EU) seeks to diversify suppliers and markets, MERCOSUR is a natural partner whose importance cannot be “underestimated”.

For Portugal, “the current delicate context makes us appreciate even more the mutual advantages of the Agreement between the EU and MERCOSUR,” João Gomes Cravinho said, without directly referring to the conflict between Russia and Ukraine.

“At a time when the EU is seeking to diversify suppliers and markets in order to ensure greater strategic autonomy, MERCOSUR is a natural partner, whose importance we cannot underestimate“, the minister added at a conference entitled “Brazil and Portugal: perspectives for the future”, which takes place from Thursday to Friday at the Gulbenkian Foundation in Lisbon.

The Southern Common Market (MERCOSUR) is a South American economic bloc created in 1991, whose founding members are Brazil, Argentina, Paraguay and Uruguay.

But still, within the framework of the European Union, Joao Gomes Cravinho believed that EU strategic partnership with Brazil left ‘untapped’.

The Minister stressed that in the context of the EU, Portugal “always knew how to use its position in favor of strengthening relations with Brazil.”

Therefore, it was during the Portuguese presidency, in 2007, that a “strategic partnership with Brazil” was established, he stressed.

However, according to the head of Portuguese diplomacy, this is “a partnership that has clearly not been used for a variety of reasons and which still retains the ability to position Brazil as Europe’s great interlocutor for South America.”

With regard to bilateral relations between the two countries, the minister emphasized that “in this context of global turmoil, the wisdom of the central characteristic common to the foreign policy of Brazil and Portugal, which is active participation in many multilateral structures, in recognition of the indispensability of multilateralism, international cooperation and global rules based order.

Portugal meets with Brazil in all areas of Portuguese foreign policy. We are Atlantic, we are Ibero-American and Portuguese-speaking,” he said.

In the Atlantic dimension, “Portugal and Brazil are united by an ocean, which we recognize as growing in importance in the context of new, complex and truly existential issues,” he said.

According to João Gomes Cravinho, “Some of these problems can be answered in the Atlantic Center, co-founded by Portugal and Brazil”, and “the other part of the huge ocean problems will be addressed in detail at the great Summit.” Oceans”, which will be held in Lisbon next week.

“In any of the areas, new prospects are opening up for Portuguese-Brazilian relations,” he stressed.

With regard to Ibero-America, the minister believes that Portugal and Brazil share “an enormous strategic space with the Castilian-speaking countries, where a joint Portuguese-Brazilian reflection is undoubtedly recommended on the potential to exploit opportunities and create synergies”.

“Value of CPLP [Comunidade de Países de Língua Portuguesa] is gaining more and more recognition at the international level – and the evidence of this is the growing number of states that become associate observers” of the organization, he believes.

“Because they want to engage with us and reinforce the value of the linguistic, cultural and historical ties that unify lusophony and create a unique dynamic for relationships with third parties,” he stressed.

But even at this level, he argued that there was an urgent need to find a “convergence of visions and desires” that “allows us to enhance” our “separate realities.”

The minister also mentioned that “despite the break caused by the pandemic”, Portugal has a “real air bridge” with Brazil, consisting of more than 74 weekly TAP flights, which is a cause and effect of “a dynamic that is being updated and reinvented”. relations between the two countries.

This dynamic, according to Gomes Cravinho, is also reflected in economic and commercial relations.

Thus, “Brazil is the first Latin American export market for Portuguese merchandise and is already the fourth largest merchandise export destination (outside the EU).

“However, the conviction remains that the potential is far from being realized, and that nostalgia for the future entails a vision of a different profile of our exchanges, a technological, creative profile that corresponds to global geo-economic transformations,” he defended. .

At this stage, João Gomes Cravinho also underlined the potential of the port of Sines, “whose strategic importance, which has long been noted, takes on new importance in the troubled times that we are going through.”
